X-ray analysis of JWST's first galaxy cluster lens SMACS J0723.3-7327
A. Liu, E. Bulbul, M. E. Ramos-Ceja +10
SMACS~J0723.3-7327 is the first galaxy cluster lens observed by JWST. Based on the ERO data from JWST, several groups have reported the results on strong lensing analysis and mass…
The first look at Narrow-Line Seyfert 1 Galaxies with eROSITA
G. Grünwald, Th. Boller, S. Rakshit +6
We present the first look at the spectral and timing analysis of Narrow-Line Seyfert 1 Galaxies (NLS1s) with the extended ROentgen Survey with an Imaging Telescope Array (eROSITA)…
On the patchy appearance of the circum-Galactic medium and the influence of foreground absorption
G. Ponti, J. S. Sanders, N. Locatelli +10
Recent studies have demonstrated that the emission from the circumgalactic medium of the Milky Way displays a relatively high degree of patchiness on angular scales of $\sim10^\cir…
Abundance and temperature of the outer hot circum-Galactic medium: The SRG/eROSITA view of the soft X-ray background in the eFEDS field
G. Ponti, X. Zheng, N. Locatelli +14
Despite their vital importance to understand galaxy evolution and our own Galactic ecosystem, our knowledge of the physical properties of the hot phase of the Milky Way is still in…
A new X-ray tidal disruption event candidate with fast variability
J. Hampel, S. Komossa, J. Greiner +3
During a close encounter between a star and a supermassive black hole, the star can get disrupted by the black hole's tidal forces, resulting in a tidal disruption event (TDE). The…
The eROSITA extragalactic CalPV serendipitous catalog
Teng Liu, Andrea Merloni, Julien Wolf +21
The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory performed calibration and performance verification (CalPV) observations between September 2019 an…
