The hot circumgalactic medium in the eROSITA All-Sky Survey III. Star-forming and quiescent galaxies
Yi Zhang, Johan Comparat, Gabriele Ponti +17
The circumgalactic medium (CGM), as the gas repository for star formation, might contain the answer to the mysterious galaxy quenching and bimodal galaxy population origin. We meas…
A magnetised Galactic halo from inner Galaxy outflows
He-Shou Zhang, Gabriele Ponti, Ettore Carretti +12
Magnetic halos of galaxies are crucial for understanding galaxy evolution, galactic-scale outflows, and feedback from star formation activity. Identifying the magnetised halo of th…
The SRG/eROSITA all-sky survey. X-ray emission from the warm-hot phase gas in long cosmic filaments
X. Zhang, E. Bulbul, N. Malavasi +24
The properties of the warm-hot intergalactic medium (WHIM) in cosmic filaments are among the least quantified units in modern astrophysics. The Spectrum Roentgen Gamma/eROSITA All…
Morphological Evidence for the eROSITA Bubbles Being Giant and Distant Structures
Teng Liu, Andrea Merloni, Jeremy Sanders +13
There are two contradictory views of the eROSITA bubbles: either a 10 kpc-scale pair of giant bubbles blown by the Galactic center (GC), or a 100 pc-scale local structure coinciden…
The SRG/eROSITA All-Sky Survey: Large-scale view of the Centaurus cluster
Angie Veronica, Thomas H. Reiprich, Florian Pacaud +9
Methods. We utilized the combined five SRG/eROSITA All-Sky Survey data (eRASS:5) to perform X-ray imaging and spectral analyses of the Centaurus cluster in various directions to la…
On the Evidence for Molecular Outflows in High-redshift Dusty Star-forming Galaxies
James Nianias, Jeremy Lim, Michael Yeung
Galactic-scale outflows of molecular gas from star-forming galaxies constitute the most direct evidence for regulation of star formation. In the early universe (), such ou…
Using SRG/eROSITA to estimate soft proton fluxes at the ATHENA detectors
E. Perinati, M. Freyberg, M. C. H. Yeung +5
Context: Environmental soft protons have affected the performance of the X-ray detectors on board Chandra and XMM-Newton, and they pose a threat for future high energy astrophysics…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
A. Merloni, G. Lamer, T. Liu +142
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…
eROSITA narrowband maps at the energies of soft X-ray emission lines
Xueying Zheng, Gabriele Ponti, Nicola Locatelli +10
[abridged] Hot plasma plays a crucial role in regulating the baryon cycle within the Milky Way, flowing from the energetic sources in the Galactic center and disc, to the corona an…
The hot circumgalactic medium in the eROSITA All-Sky Survey II. Scaling relations between X-ray luminosity and galaxies' mass
Yi Zhang, Johan Comparat, Gabriele Ponti +16
Understanding how the properties of galaxies relate to the properties of the hot circum-galactic medium (CGM) around them can constrain galaxy evolution models. We measured the X-r…
The hot circumgalactic medium in the eROSITA All-Sky Survey I. X-ray surface brightness profiles
Yi Zhang, Johan Comparat, Gabriele Ponti +17
The circumgalactic medium (CGM) provides the material needed for galaxy formation and influences galaxy evolution. The hot () CGM is poorly detected around galaxies with s…
