Astronomers at the Max Planck Institute for Astrophysics, using the Atacama Large Millimeter/submillimeter Array (ALMA), have revealed an extremely distant and therefore very young galaxy that looks surprisingly like our Milky Way. The galaxy is so far away its light has taken more than 12 billion years to reach us: we see it as it was when the Universe was just 1.4 billion years old. It is also surprisingly unchaotic, contradicting theories that all galaxies in the early Universe were turbulent and unstable. This unexpected discovery challenges our understanding of how galaxies form, giving new insights into the past of our Universe. more

When interstellar gas falls towards a supermassive black hole, it liberates vast amounts of energy - so vast as to be capable of ejecting much of a galaxy’s gaseous reservoir. Ultimately, supermassive black holes may thus deprive themselves of further fuel and bring about the end of their own growth and that of their host galaxies. A new model developed at MPA now makes it possible to simulate winds accelerated by accreting black holes in galaxy evolution simulations in a physically accurate and validated way. By blowing dense gas from the galactic nucleus, and by halting inward flows from the galactic halo, the winds play a vital role in shaping the evolution of the black hole host galaxy. more

Two teams of astronomers have made a compelling case in the 33-year-old mystery surrounding Supernova 1987A. Based on observations with ALMA and a theoretical follow-up study, the scientists provide new insight for the argument that a neutron star is hiding deep inside the remains of the exploded star. This would be the youngest neutron star in our cosmic neighbourhood known to date. more

Astrophysicist Sherry H. Suyu will receive the 2021 Lancelot M. Berkeley–New York Community Trust Prize for Meritorious Work in Astronomy. Bestowed annually since 2011 by the American Astronomical Society (AAS) and supported by a grant from the New York Community Trust, the Berkeley prize includes a monetary award and an invitation to give the closing plenary lecture at the AAS winter meeting, the “Super Bowl of Astronomy.” The 237th AAS meeting will be held virtually from 11 to 15 January 2021. more

Recently, in correspondence with the 10th birthday of LOFAR, a core group of researchers including MPA scientists published the most stringent upper limits on the reionization signal from the early Universe. These observations are able to exclude some reionization models and constrain the thermal and ionization state of the intergalactic medium when the Universe was still in its infancy. more

During its general meeting, the Max Planck Society announced that former MPA PhD student Jens Stücker receives one of the Otto Hahn Medals this year. The prize is awarded for numerical investigations of the dark matter phase-space structure in the smallest halos, thereby allowing to better distinguish between Warm and Cold Dark Matter. more
