Key contributions from Max Planck and Leibniz Universität Hannover researchers to second gravitational-wave event found in LIGO data

On December 26, 2015 the LIGO instruments detected a second gravitational wave. The observed signal originated from a pair of merging black holes of about 14 and 8 solar masses – smaller than the ones detected on September 14, 2015. Researchers from the Max Planck Institute for Gravitational Physics in Potsdam and Hannover and the Leibniz Universität Hannover have contributed to the discovery in several key areas: the development of highly accurate gravitational-wave models, searches to detect faint signals, assessment of their statistical significance, determining their astrophysical parameters, and advanced detector technology. This second discovery proves that a new era of gravitational-wave astronomy has begun.

The Faculty Senate of Chalmers University of Technology will bestow the degree Doctor of Technology on Prof Dr Hermann Nicolai, director at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI). The ceremony for conferring the doctor's degree will take place on Saturday, May 14th 2016 in Gothenburg, Sweden.

May 9th 2016

Scientists at the Max Planck Institute for Gravitational Physics in Potsdam develop an accurate model for the detection and interpretation of gravitational waves emitted by neutron stars in binary systems. This model contains, for the first time, a realistic description of how neutron stars are deformed just before they collide. As the deformation depends on the exotic physics in neutron star interiors and directly influences the gravitational waves more detailed information about the science contained in the expected signals is now available. This will enable more robust measurements leading to an improved understanding of the properties of the densest objects in our universe.

Max Planck Scientists Find Evidence for Stellar Companion's Activity Cycles

Pulsars are rapidly rotating compact remnants born in the explosions of massive stars. They can be observed through their lighthouse-like beams of radio waves and gamma-rays. Scientists at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute, AEI) in Hannover, Germany, now have precisely measured the properties of a binary star system with a gamma-ray millisecond pulsar. Using new methods, the researchers analyzed archival data from the Fermi Gamma-ray Space Telescope more precisely than possible before. They discovered variations in the orbital period of the interacting binary system that can be explained by magnetic activity cycles of the companion star.

While the LISA Pathfinder (LPF) satellite is undergoing its last tests before shipping to the launch site and the launch in autumn, the LPF scientists prepare for the mission operations.

Next steps: Shipment to Kourou and launch in autumn

After more than 10 years of intense development, the highly sensitive science payload of the LISA Pathfinder Mission (LPF) has been completed and integrated into the satellite.  The science instruments are the core of the mission.
“LISA Pathfinder will test novel technologies in space whose function and performance cannot be tested on the ground at all or only in a limited fashion. LPF will pave the way for the gravitational wave observatory eLISA,” says Prof. Karsten Danzmann, Director at the AEI and professor at the Leibniz Universität Hannover. eLISA (evolved Laser Interferometer Space Antenna) is scheduled for launch in 2034.

The Advanced LIGO Project, a major upgrade that will increase the sensitivity of the Laser Interferometer Gravitational-wave Observatories instruments by a factor of 10 and provide a 1,000-fold increase in the number of astrophysical candidates for gravitational wave signals, will be officially dedicated in a ceremony to be held on Tuesday, May 19, at the LIGO Hanford facility in Richland, Washington.
LIGO was designed and is operated by Caltech and MIT, with funding from the National Science Foundation (NSF). Advanced LIGO, funded by the NSF with important contributions from the UK Science and Technology Facilities Council (STFC), the Max Planck Society of Germany, and the Australian Research Council (ARC), is now being brought online, with the first searches for gravitational waves planned for the fall of 2015.

A large step closer to the first direct detection of gravitational waves

On May 19, the LIGO Scientific Collaboration (LSC) will dedicate their second-generation gravitational-wave detectors (aLIGO) in a ceremony at the Hanford detector site.

For almost 20 years, Prof. Bernard F. Schutz has played a key role in the international success of the Max Planck Institute for Gravitational Physics. His tenure as a Director of the institute has now come to an end, but this certainly does not equate to retirement. He will remain associated with his Institute as an Emeritus Director, and at the same time take up a part-time professorship at Cardiff University.  “I will be able to dedicate myself completely to research, the Open Access movement and to the Data Innovation Institute, which has recently been founded at Cardiff University”, says Prof. Schutz, describing his plans for the future.

From the 5th issue

Major milestone: First full lock achieved!
After many years of planning, design, assembly and installation, Advanced LIGO is finally entering integrated testing, where all the subsystems have to be made to work together. This process can be separated into two phases: First, the systems that automatically bring the detector to its operating point and keep it there must be made to work – this is called “locking.” Secondly, we must achieve low noise readout of the differential arm strain, to allow “science mode” data collection.

ESA decides on next Large Mission Concepts

The Gravitational Universe will be one of the two science themes to be explored by ESA's next two Large (L-class) missions – this was decided today by ESA's Science Programme Committee (SPC).

The suggested mission to probe the Gravitational Universe is the evolved Laser Interferometer Space Antenna (eLISA). It will study the universe in a unique way – completely differently from any other space observatory – by detecting gravitational waves. Observations of gravitational waves in space will answer key scientific questions about the astrophysics of the cosmic dawn and the physics and evolution of the universe. According to ESA's decision, eLISA will be the third L-class mission, following JUICE and Athena+.

Einstein@Home volunteers find four cosmic lighthouses in data from NASA's Fermi Gamma-ray Space Telescope

The combination of globally distributed computing power and innovative analysis methods proves to be a recipe for success in the search for new pulsars. Scientists from the Max Planck Institutes for Gravitational Physics and Radio Astronomy together with international colleagues have now discovered four gamma-ray pulsars in data from the Fermi space telescope. The breakthrough came using the distributed computing project Einstein@Home, which connects more than 200,000 computers from 40,000 participants around the world to a global supercomputer.

A new approach to the unification of General Theory of Relativity and Quantum Theory

Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only an all-encompassing theory of quantum gravity which unifies these two fundamental pillars of physics could provide an insight into how the universe began. Scientists from the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Golm/Potsdam and the Perimeter Institute in Canada have made an important discovery along this route.

Physicists from the Max Planck Society and Leibniz Universität Hannover develop a new concept to improve the sensitivity of gravitational-wave detectors

Laser interferometers detect tiny distance changes with high precision. Stray light reduces and limits the measurement accuracy of these instruments. Researchers at the Albert Einstein Institute in Hannover have now shown for the first time how to discriminate between measurement signal and stray light using lasers with tailored quantum properties. The novel measurement concept circumvents the Heisenberg uncertainty principle and could enhance the precision of gravitational-wave detectors like GEO600 or the closely cooperating Advanced LIGO (aLIGO) detectors in the USA.

Max Planck scientists discover record-breaking millisecond pulsar with new analysis method

Pulsars are the compact remnants from explosions of massive stars. Some of them spin around their own axis hundreds of times per second, emitting beams of radiation into space. Until now, they could only be found through their pulsed radio emissions. Now, scientists at the Max Planck Institute for Gravitational Physics (Albert Einstein Institute/AEI) in Hanover assisted by the Max Planck Institute for Radio Astronomy have discovered a millisecond pulsar solely via its pulsed gamma radiation. A new data analysis method developed by the AEI was crucial for the success. The pulsar is accompanied by an unusual sub-stellar partner, which it is vaporizing, hence the name “black widow”.

Journalist Robin McKie from the UK newspaper The Observer has won the special award for excellence of the first European Journalism Prize for his piece "Hunting ripples in the fabric of space".

The article on British involvement in the search for gravitational waves was first published in the Discover Physics section of the printed version of The Observer.

European gravitational wave community strengthens its space collaboration

During the 9th international LISA Symposium, held May 21 – 25 in Paris, the international LISA* community analyzed the new situation after ESA´s decision to choose JUICE for Europe´s next large space science mission. As the eLISA** mission, despite not being selected, was reported to have been unanimously ranked first by ESA´s scientific review committee in terms of scientific interest, strategic value for science and strategic value for the projects in Europe, the community is in good spirits: this is the first time that any space agency committee has ranked a gravitational wave observatory as the agency´s highest scientific priority. In order to prepare a strongest possible bid for the next launch opportunity the community has decided to continue its collaboration as the self-funded and independent eLISA consortium.

eLISA/NGO is a new concept for observing gravitational waves in space.

eLISA/NGO (evolved Laser Interferometer Space Antenna/New Gravitational Wave Observatory) will add a new sense to our perception of the Universe - for the first time we will observe e.g. Black holes and Neutron stars directly and gain unique information about the behaviour, structure and early history of the Universe.

05. August 2011

Scientists operating Europe’s gravitational wave observatories have combined efforts this summer to search for gravitational waves.

This groundbreaking research is being taken forward in Europe while similar US-based detectors undergo major upgrade work.

Cataclysmic cosmic events such as supernovae, colliding neutron stars and black holes, as well as more familiar objects such as rotating neutron stars (pulsars) are expected to emit gravitational waves – oscillations in the fabric of space-time predicted by Einstein’s Theory of General Relativity. The detection of such waves would revolutionise our understanding of the Universe.

The neutron star and its companion could prove helpful in testing the general theory of relativity

Neutron stars are quite unique: the material they are made of is packed much more densely than conventional matter. They rotate extremely fast about their own axis, emitting radiation in the process, so they are often visible as pulsars in the radio spectrum. Researchers at the Max Planck Institute for Gravitational Physics in Hanover, working as part of the international PALFA Collaboration, and with the help of participants in the Einstein@Home project, have now discovered a pulsar accompanied by a white dwarf – a burnt-out star. The researchers want to weigh the pair, using what is known as the Shapiro effect. (Astrophysical Journal Letters, 732/1 L1)

Second discovery with Einstein@Home: J1952+2630 - a neutron star with a binary companion

Neutron stars are exotic objects. They consist of material that is much denser than normal matter; at similar densities the entire mass of the earth would form a ball about 260 m in diameter. Neutron stars spin quickly, sending out radiation like a lighthouse. They are most often visible as radio pulsars.

The test mission for the gravitational wave detector in space LISA has reached an important milestone after a rigorous review of the whole mission

Gravitational waves tell of star explosions, the collision of black holes and even the Big Bang itself. The space-based gravitational wave detector LISA (Laser Interferometer Space Antenna) will observe the gravitational waves from coalescing binary black holes among other sources, beginning its search for the elusive signals in 2020. Working in conjunction with other astronomical methods and gravitational wave observatories on Earth, we will then be able to observe the unknown and uncharted – the so-called "Dark Side of the Universe".
