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”.

The evolution of Advanced LIGO
Starting in late 2007 and ending in 2015, the Advanced LIGO (aLIGO) Project will deliver detectors which will have locked for several hours and will be capable, after post-Project tuning, of a factor of 10 improvement in sensitivity over initial LIGO.

Monolithic Suspensions: From the Lab to Advanced LIGO
At the heart of each Advanced LIGO (aLIGO) detector are four large mirrors – test masses – made of fused silica, two in each arm of the interferometer.

Psychology can make this world a better place. This is one of the conclusions out of five days of meetings, talks, presentations and discussions of about 6000 participants at the International Congress of Psychology (ICP) 2012 in Cape Town South Africa. "To meet the challenges of the changes we are witnessing across the world, be it due to scientific advances, or financial catastrophes, to political transformation, or climate change and ecological fragility, we have to come together more than ever before." said Rainer K.

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 (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.

Professor Bernard Schutz has played a major part in developing fruitful collaborations between theoretical and experimental astrophysicists worldwide, particularly in the field of gravitational wave detection.

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)

How neutron stars merge - first accurate calculation of the last orbits of binary systems of neutron stars. AEI scientists described for the first time new numerical methods for the calculation of gravitational wave signals.

An article describing an important progress in modelling the last orbits of binary systems of neutron stars has been recently published in Physical Review Letters

HANNOVER/Germany & PASADENA, Calif. — The US National Research Council (NRC) has strongly recommended the Laser Interferometer Space Antenna (LISA) as one of NASA's next two major space missions, to start in 2016 in collaboration with the European Space Agency (ESA). LISA will study the universe in a manner different from any other space observatory, by observing gravitational waves. The recommendation was announced today in a press conference at the Keck Center of the National Academies in Washington, D.C.

The open access physics journal Living Reviews in Relativity, published by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) in Potsdam, has received its first impact factor of 10.600 in the 2009 Journal Citation Reports released by Thomson Reuters on June 17, 2010. The unique review journal already ranks second worldwide in the category Physics, Particles & Fields.
