NASA News:
X-ray Satellite XMM-Newton Sees ‘Space Clover’ in a New Light

Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies.

MPE News:
Cosmic dance of the ‘Space Clover’

A groundbreaking discovery by the team led by Dr. Bulbul unveiled the origin of the ORC as a cosmic dance of two galaxy groups, leveraging the advanced capabilities of the XMM-Newton telescope.


eROSITA relaxes cosmological tension

Results from the first X-ray sky survey resolve the previous inconsistency between competing measurements of the structure of the Universe

X-ray survey bolsters prevailing theory of universe’s expansion


eROSITA telescope shows galaxies’ “clumpiness” matches predicted effect of dark energy, dark matter prevailing theory of universe’s expansion


Nature News:
This new map of the Universe suggests dark matter shaped the cosmos

The eROSITA telescope’s detailed pictures are among the most precise cosmological measurements ever made.


Sky & Telescope:
Largest-ever Catalog of X-ray Sources Tests Cosmology 

Results from a brand-new high-energy observatory are rocking the field of cosmology. In particular, a study of more than 5,000 galaxy clusters relieves tension in the standard cosmological model.

eROSITA Cosmology Results will be announced on Feb 14

The X-ray sky opens to the world

The first All Sky observations of SRG/eROSITA in the Western Galactic Hemisphere are released to the public by the German eROSITA Consortium (eROSITA-DE) on Jan 31, 2024. 


2023 AG Poster Prize goes to Fabian Balzer

September, 2023

A heartfelt congratulations goes to the Ph.D. student in the eROSITA clusters and cosmology group, Fabian Balzer, for receiving the 2023 German Astronomical Society (AG) Poster Award. Fabian is a graduate student at MPE working on the optical follow-up of the clusters of galaxies detected by eROSITA.

A mini-survey called “eFEDS” (the eROSITA Final Equatorial Depth Survey). designed as a preview to the final all-sky survey, eFEDS covers uniformly a patch of about 140 square degrees of the sky (about 1/300th of the all-sky survey), providing a glimpse of what the whole extra-galactic sky will look like in X-rays after eROSITA completes its all-sky survey program in 2023. Astronomers led by Ang Liu discovered more than 477 clusters of galaxies and 19 super clusters in this field, demonstrating the potential of eROSITA of detecting clusters for cosmology.

Containing various structures with a range of masses, from massive and dense clusters of galaxies to low-density bridges, filaments and sheets of matter, superclusters are among the largest structures in the known universe. Finding and investigating superclusters in detail could be essential in order to improve our understanding of the formation and evolution of large cosmic filaments.A group of astronomers led by Vittorio Ghirardini of the Max Planck Institute for Extraterrestrial Physics in Garching, Germany, reports the discovery of a new supercluster. The structure was identified by the eFEDS survey during its Performance Verification (PV) phase.

The project "DarkQuest: Shedding Light on the Nature of Dark Matter and Dark Energy with Multi-Wavelength All-Sky Surveys" led by Esra Bulbul at MPE is being funded by an ERC Consolidator grant for the next five years. Taking advantage of the eROSITA survey data, she aims to constrain dark energy and dark matter models.
