Investigating central star formation in local AGN host galaxies: is there tension between coeval growth and AGN feedback?

Q. Ni, K. Nandra, A. Merloni +3

It has been argued that supermassive black holes (BHs) coevolve with the central parts of galaxies, as a result of the common fuel for both the BH and star formation in the galaxy…

The impact of assembly history on the X-ray detectability of halos. From galaxy groups to galaxy clusters

I. Marini, P. Popesso, K. Dolag +15

Galaxy groups represent a significant fraction of the halo population, playing a crucial role in galaxy formation and evolution. However, their detection in X-rays remains challeng…

Average X-ray properties of galaxy groups. From Milky Way-like halos to massive clusters

P. Popesso, I. Marini, K. Dolag +20

This study examines the average X-ray properties of massive halos at z< 0.2, covering the largest halo mass range to date, from Milky Way-like halos to massive clusters. The analys…

The perils of stacking optically selected groups in eROSITA data. The Magneticum perspective

P. Popesso, I. Marini, K. Dolag +23

Hydrodynamical simulation predictions are often compared with observational data without fully accounting for systematics and biases specific to observational techniques. Using the…

O Corona, where art thou? eROSITA's view of UV-optical-IR variability-selected massive black holes in low-mass galaxies

R. Arcodia, A. Merloni, J. Comparat +16

Finding massive black holes (MBHs, ) in the nuclei of low-mass galaxies () is crucial to constrain seeding and…
