Kippenhahn Award for two junior MPA scientists

October 24, 2017
Two junior MPA scientists receive the Kippenhahn Award for the best MPA student publication in 2016. Titouan Lazeyras receives the prize for his paper "Large-scale assembly bias of dark matter halos" which presents high-precision measurements of halo assembly bias. Dijana Vrbanec was awarded for her paper "Predictions for the 21 cm-galaxy cross-power spectrum observable with LOFAR and Subaru"; finding that a clear anti-correlation should be seen on scales larger than the typical separation distance between galaxy clusters.

Gravitational waves and emitted light reveal merger of two neutron stars – and a kilonova

October 16, 2017
On 17 August 2017, two merging neutron stars were seen for the first time by their gravitational wave signal as well as high-energy gamma radiation. This simultaneous observation confirms that merging neutron stars are indeed the progenitors of short Gamma-Ray Bursts. Follow-up observations revealed light emission powered by the radioactive decay of heavy elements – a so-called kilonova, confirming theoretical predictions, also by scientists at the Max Planck Institute for Astrophysics, that these kinds of stellar collisions can be the cosmic origin of heavy elements such as gold and platinum.

Volker Springel appointed as new director at MPA

October 05, 2017
From 1st October 2017, Volker Springel is a new director at the Max Planck Institute for Astrophysics and head of the "Numerical Astrophysics" department, initially with a partial appointment and from 1st August 2018 full-time. The theoretical astrophysicist, whose main research focus is on structure formation in the Universe and the simulation of galaxies, returns to Garching and the institute where his scientific career began.

Rise and Shine: Type Ia supernova models at early times

October 01, 2017
Type Ia supernovae (SNe Ia) are spectacular explosions in white dwarf stars and play an essential role in astrophysics in general and in cosmological studies in particular. However, many puzzles about the nature and the inherent physical mechanisms in SNe Ia are still waiting to be answered. Robotic surveys of the next decade will provide an unprecedented wealth of observed Type Ia supernovae, detected shortly after explosion. Researchers at MPA examine here whether different explosion models are expected to leave clear imprints in such early observations that could be used in future photometric surveys to help shedding light on the progenitors and explosion mechanism of SNe Ia.

Progenitor for Tycho’s supernova was not hot and luminous

September 25, 2017
An international team of scientists from the Monash University (Melbourne, Australia), the Towson and Pittsburgh Universities (USA) and the Max Planck Institute for Astrophysics, has shed new light on the origins of the famous Tycho’s supernova. The research, published in Nature Astronomy, debunks the common view that Tycho’s supernova originated from a white dwarf, which had been slowly accreting matter from its companion in a binary system.

Rashid Sunyaev becomes 2017 Citation Laureate

September 20, 2017
Each year since 2002, analysts at Clarivate Analytics (formerly Thomson Reuters) mine millions of citations in the Web of Science to identify top-tier researchers in physiology, medicine, physics and chemistry as well as economics. MPA director Rashid Sunyaev is one of five 2017 physics laureates for his “profound contributions to our understanding of the Universe, including its origins, galactic formation processes, disk accretion of black holes, and many other cosmological phenomena.” [more]
