What's Missing in AGN Feedback? Lessons learnt from Magneticum, IllustrisTNG and Simba
D. T. Mazengo, P. Popesso, I. Marini +20
Accurately balancing gas reservoirs, star formation, and feedback across cosmic time remains a central challenge for galaxy formation models in modern hydrodynamical simulations. W…
Spatially resolved optical and mid-infrared spectroscopy of SDSS1335+0728: implications for the origin of the Ansky event
P. Sánchez-Sáez, M. Masterson, L. Hernández-García +25
The galaxy SDSS1335+0728 brightened abruptly in December 2019 (the Ansky event) and has since been confirmed as the host of extreme X-ray quasi-periodic eruptions (QPEs) of debated…
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…
Discovery of Quasar Variability and Early Accretion Disk Signatures at Cosmic Dawn
Gene C. K. Leung, Anna-Christina Eilers, Christos Panagiotou +12
In the nearby universe, quasars are well known to exhibit variability in their brightness over time, offering a powerful tool to probe the physics of accretion onto the SMBH and di…
Robust AGN and host-galaxy decomposition in optical spectral fitting
C. Aydar, A. Merloni, G. Zeltyn +24
Unraveling the growth of supermassive black holes and their connection to host galaxies requires disentangling the Active Galactic Nuclei (AGN) emission from that of the stellar po…
Low-mass stars dominate the hot (0.7 keV) Galactic X-ray emission
G. Ponti, M. C. H. Yeung, G. Stel +12
The circumgalactic medium (CGM) of the Milky Way is composed of a tenuous atmosphere filled with multi-phase plasma, including a warm-hot virialised component. Recent studies sugge…
The Nineteenth Data Release of the Sloan Digital Sky Survey
SDSS Collaboration, Gautham Adamane Pallathadka, Mojgan Aghakhanloo +210
Mapping the local and distant Universe is key to our understanding of it. For decades, the Sloan Digital Sky Survey (SDSS) has made a concerted effort to map millions of celestial…
The eROSITA view on the halo mass-temperature relation: From low-mass groups to massive clusters
V. Toptun, P. Popesso, I. Marini +15
Galaxy groups and clusters are among the best probes of structure formation and growth in a cosmological context. Most of their baryonic component is dominated by the intracluster…
Cross-correlation between soft X-rays and galaxies A new benchmark for galaxy evolution models
Johan Comparat, Andrea Merloni, Gabriele Ponti +11
This article presents the construction and validation of complete stellar mass-selected, volume-limited galaxy samples using the Legacy Survey (data release 10) galaxy catalogs, co…
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…
The First SRG/eROSITA All-Sky Survey. Characterization of clusters of galaxies misclassified in the eRASS1 point source catalog
F. Balzer, E. Bulbul, M. Kluge +20
The detection of the extended X-ray-emission of the intracluster medium by the first SRG/eROSITA All-Sky Survey (eRASS1), combined with optical and near-infrared follow-up, resulte…
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 hot gas mass fraction in halos. From Milky Way-like groups to massive clusters
P. Popesso, A. Biviano, I. Marini +21
By using eROSITA data in the eFEDS area, we provide a measure of the hot gas fraction vs. halo mass relation over the largest halo mass range, from Milky Way-sized halos to massive…
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…
CircleZ: Reliable Photometric redshifts for AGN computed using only photometry from Legacy Survey Imaging for DESI
A. Saxena, M. Salvato, W. Roster +25
(abridged)Photometric redshifts for AGN (galaxies hosting an accreting supermassive black hole in their center) are notoriously challenging and currently better computed via SED fi…
SDSS1335+0728: The awakening of a black hole
P. Sánchez-Sáez, L. Hernández-García, S. Bernal +22
The galaxy SDSS1335+0728, which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Fa…
