Reproducing the large-scale Universe

Reproducing the large-scale Universe

by Kerstin Mork last modified Feb 19, 2016 11:10 AM

16 February 2016. The BOSS survey has scanned the sky measuring the redshifts of more than 1 million galaxies, yielding a three dimensional picture of luminous sources in our Universe covering about 4.5 billion years. An international team of astronomers has now reproduced the observed galaxy clustering and determined the uncertainties in the measurement of observed quantities by generating thousands of simulated galaxy catalogues. For the first time, the separation between pairs of galaxies, and the separation between triplets of galaxies has been explicitly constrained to reproduce the observations. Hence, the cosmic web in particular the empty regions between galaxies are described.

Leibniz Institute for Astrophysics Potsdam (AIP) validated by excellent evaluation result

by Kerstin Mork last modified Mar 07, 2016 02:19 PM

30 November 2015. The Leibniz Institute for Astrophysics Potsdam (AIP) was given excellent marks in the independent evaluation process by the Leibniz Association, which takes place every seven years. The development of the institute over the past years was described to be extremely successful. AIP has taken important and clever strategic decisions in continually developing and extending its instrumentation and computer-aided infrastructure. The senate of the Leibniz Association has now confirmed the results of the evaluation, recommending continued funding by the federal government and the federal states.

First movie of stellar-surface evolution beyond our Solar System

First movie of stellar-surface evolution beyond our Solar System

by Kerstin Mork last modified Oct 21, 2015 09:05 AM

20 October 2015. Astronomers from the Leibniz Institute for Astrophysics Potsdam (AIP), present for the first time a movie that shows the evolution of stellar spots on a star other than our Sun. The long-term, highly-sampled, phase-resolved spectroscopic data were made possible with the STELLA robotic telescopes on Tenerife. Over a period of 6 years the growth and fade of giant stellar spots on the star XX Tri are seen. The spots reveal an underlying magnetic cycle that has a period comparable to our Sun’s but is much stronger.

Starry surprise in the bulge: encounter of a halo passerby

21 July 2015. A team led by Andrea Kunder from the Leibniz Institute for Astrophysics Potsdam (AIP) measured the velocity of a sample of 100 old RR Lyrae stars* thought to reside in the Galactic bulge, the central group of stars found in most Galaxies.

A Dark Matter bridge in our cosmic neighborhood

A Dark Matter bridge in our cosmic neighborhood

by Kerstin Mork last modified Jul 14, 2015 09:13 AM

14. Juli 2015. By using the best available data to monitor galactic traffic in our neighborhood, Noam Libeskind from the Leibniz Institute for Astrophysics Potsdam (AIP) and his collaborators have built a detailed map of how nearby galaxies move. In it they have discovered a bridge of Dark Matter stretching from our Local Group all the way to the Virgo cluster - a huge mass of some 2,000 galaxies roughly 50 million light years away, that is bound on either side by vast bubbles completely devoid of galaxies. This bridge and these voids help us understand a 40 year old problem regarding the curious distribution of dwarf galaxies.

5 May 2015. The Leibniz Institute for Astrophysics Potsdam (AIP), in collaboration with Hamburger Sternwarte and Dr. Remeis-Sternwarte Bamberg, is digitizing an archive of astronomical photographic plates as a means to preserve cultural heritage. These photographic plates contain observations spanning nearly 100 years. They provide precious longterm information which can be mined by modern data extraction techniques. The project is supported by a DFG grant (German Research Funding Organisation).

Largest catalogue of  X-ray detected astrophysical objects published

Largest catalogue of X-ray detected astrophysical objects published

by Kerstin Mork last modified Oct 20, 2015 03:36 PM

28 April 2015. A systematic analysis of all observations performed so far by the X-ray satellite XMM-Newton resulted in the worlds most comprehensive catalogue of X-ray detected celestial objects. It was compiled and published by a science consortium, the XMM-Newton Survey Science Centre, the AIP being one of its members. The catalogue, called 3XMM-DR5, lists 565 962 X-ray detections, ranging from nearby objects in our Solar System to supermassive black holes at the edge of the Universe. For each detection, a wealth of information is provided to help understand the nature of the object and as a result, many new and extreme astrophysical objects will be discovered.

To flare or not to flare: The riddle of galactic thin–thick disk solved

To flare or not to flare: The riddle of galactic thin–thick disk solved

by Kerstin Mork last modified Mar 29, 2016 03:59 PM

24 April 2015. A long-standing puzzle regarding the nature of disk galaxies has finally been solved by a team of astronomers led by Ivan Minchev from the Leibniz Institute for Astrophysics Potsdam (AIP), using state-of-the-art theoretical models. The new study shows that groups of stars with the same age always flare as the result of massive galactic collisions. When taken all together, these flares, nested like the petals of a blooming rose, puff up the disk and constitute what astronomers call the “thick” disk.

First Light for PEPSI

First Light for PEPSI

by Kerstin Mork last modified Jul 02, 2015 08:51 AM

22 April 2015. The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) has received its first celestial light through the Large Binocular Telescope (LBT). Astronomers from the Leibniz Institute for Astrophysics Potsdam showed the instruments incredible capabilities at different wavelengths and resolving powers. Among the first targets were several of the bright Gaia-ESO benchmark stars, magnetically active stars, solar-like stars with planets, a solar twin in M67, Jupiter’s four Galilean moons, and the bright Nova Sgr 2015b.

Stars with the chemical clock on hold

Stars with the chemical clock on hold

by Kerstin Mork last modified Apr 07, 2016 01:49 PM

10 April 2015. An international team of astrophysicists, led by Cristina Chiappini from the Leibniz Institute for Astrophysics Potsdam, has discovered a group of red giant stars for which the ‘chemical clock’ does not work: according to their chemical signature, these stars should be old. Instead, they appear to be young when their ages are inferred using asteroseismology. Their existence cannot be explained by standard chemical evolution models of the Milky Way, suggesting that the chemical enrichment history of the Galactic disc is more complex than originally assumed.
