Using the SRG/eROSITA all-sky survey data, scientists at the MPE have found two previously quiescent galaxies that now show quasi-periodic eruptions. The nuclei of these galaxies light up in X-rays every few hours, reaching peak luminosities comparable to that of an entire galaxy. The origin of this pulsating behaviour is unclear. A possible cause is a stellar object orbiting the central black hole.
Long-awaited review reveals journey of water from interstellar clouds to habitable worlds
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have identified a previously unknown supernova remnant, dubbed “Hoinga.” The finding was confirmed in archival radio data and marks the first discovery of a joint Australian-eROSITA partnership established to explore our galaxy by using multiple wavelengths.
The Max Planck Director is honored for his observations of the black hole in the Galactic Center
Gigantic hot-gas structures above and below the galactic disc are probably due to shock waves generated by past energetic activity in the center of our Galaxy.
Stellar systems like our own are formed inside interstellar clouds of gas and dust that collapse, producing young stars surrounded by protoplanetary disks. Planets form within these protoplanetary disks, and leave clear gaps. ALMA has now revealed an evolved protoplanetary disk with a large gap still being fed by the surrounding cloud via large accretion filaments. This shows that an accretion of material onto the protoplanetary disk has been continuing for longer than previously thought, affecting the evolution of the future planetary system.
