On the baryon budget in the X-ray-emitting circumgalactic medium of Milky Way-mass galaxies
Yi Zhang, Soumya Shreeram, Gabriele Ponti +6
Recent observations with SRG/eROSITA have revealed the average X-ray surface brightness profile of the X-ray-emitting circumgalactic medium (CGM) around Milky Way (MW)-mass galaxie…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Unveiling the soft X-ray source population towards the inner Galactic disk with XMM-Newton
Tong Bao, Gabriele Ponti, Frank Haberl +5
Across the Galactic disk lies a diverse population of X-ray sources, with the fainter end remaining poorly understood due to past survey sensitivity limits. We aim to classify and…
The X-ray luminosity function of stars observed with SRG/eROSITA
Nicola Locatelli, Gabriele Ponti, Enza Magaudda +1
Background diffuse X-ray emission is contributed in large part by the emission of point sources not individually resolved. While this is established since decades for the contribut…
Impact of the large-scale cosmic web on the X-ray emitting circumgalactic medium
Soumya Shreeram, Daniela Galárraga-Espinosa, Johan Comparat +9
The hot circumgalactic medium (CGM), probed by X-ray observations, plays a central role in understanding gas flows that drive a galaxy's evolution. While CGM properties have been w…
A sample of ionised Fe line-emitting X-ray sources in the inner Galactic disc
Samaresh Mondal, Gabriele Ponti, Tong Bao +4
Previous studies suggest that the Galactic diffuse X-ray emission is composed of unresolved point sources, primarily mCVs. However, nearby mCVs have a much lower 6.7 keV line equiv…
Disentangling the Galactic centre X-ray reflection signal using XMM-Newton data
K. Anastasopoulou, I. Khabibullin, E. Churazov +5
We investigate the X-ray emission from the Galactic Centre (GC) region, focusing on the 6.4 keV fluorescent line of neutral or weakly ionised iron, which is commonly attributed to…
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…
Retrieving the hot circumgalactic medium physics from the X-ray radial profile from eROSITA with an IlustrisTNG-based forward model
Soumya Shreeram, Johan Comparat, Andrea Merloni +9
Recent eROSITA measurements of the radial profiles of the hot CGM in the Milky-Way stellar mass (MW-mass) regime provide us with a new benchmark to constrain the hot gas around MW-…
Hunting for High-Mass X-ray Binaries in the Galactic Center with NuSTAR
Shifra Mandel, Julian Gerber, Kaya Mori +9
The central deg region of our Galaxy contains X-ray point sources that were detected by a series of Chandra observations over the last two decades. Ho…
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…
eROSITA X-ray Analysis of the PeVatron Candidate Westerlund 1
Konstantin Haubner, Manami Sasaki, Alison Mitchell +7
It is unclear which fraction of cosmic rays above an energy of 1 PeV is accelerated by the observed Galactic PeVatron population. These sources' gamma-ray data is typically degener…
