Cosmic lenses support finding on faster than expected expansion of the Universe

January 26, 2017
By using galaxies as giant gravitational lenses, an international group of astronomers including researchers at the Max Planck Institute for Astrophysics have made an independent measurement of how fast the Universe is expanding. The newly measured expansion rate for the local Universe is consistent with earlier findings. These are, however, in intriguing disagreement with measurements of the early Universe. This hints at a fundamental problem at the very heart of our understanding of the cosmos. [more]

Obituary to Heinz Billing

January 10, 2017
A pioneer in the development of electronic computing machines in Germany and one of the founders of gravitational wave astronomy is gone: on 4 January 2017, the astrophysicist Heinz Billing died at the age of 102. Billing was scientific member at the Max Planck Institute for Astrophysics in Garching from 1961 to '82. [more]

Fluctuations in extragalactic gamma rays reveal two source classes but no dark matter

December 19, 2016
Researchers from the Max Planck Institute for Astrophysics and the University of Amsterdam GRAPPA Center of Excellence just published the most precise analysis so far of the fluctuations in the gamma-ray background. They used more than six years of data gathered by the Fermi Large Area Telescope and found two different source classes contributing to the gamma-ray background. No traces of a contribution of dark matter particles were found in the analysis. The study was performed with an international collaboration of researchers and is published in the journal Physical Review D. [more]

The Sky's Ancient Eye

July 25, 2016
An international team of researchers have discovered an extremely rare “double source plane” gravitational lensing system, in which two distant galaxies are simultaneously lensed by a foreground galaxy, as part of the on-going Subaru Strategic Survey with Hyper Suprime-Cam. The team dubbed the system ‘Eye of Horus’ as the system resembles this ancient Egyptian symbol.  Such a rare system is a unique probe of the fundamental physics of galaxies as well as cosmology.

1.2 Million Galaxies in 3D

July 14, 2016
What are the properties of Dark Energy? This question is one of the most intriguing ones in astronomy and scientists are one step closer in answering this question with the largest three-dimensional map of the universe so far: This map contains 1.2 million galaxies in a volume spanning 650 cubic billion light years. Hundreds of scientists from the Sloan Digital Sky Survey III (SDSS-III) – including researchers at the Max Planck Institutes for Extraterrestrial Physics and for Astrophyics - used this map to make one of the most precise measurements yet of dark energy. They found excellent agreement with the standard cosmological model and confirmed that dark energy is highly consistent with a cosmological constant. [more]
