Offset between X-ray and optical centers in clusters of galaxies: connecting eROSITA data and simulations
R. Seppi, J. Comparat, K. Nandra +6
The characterization of the dynamical state of clusters is key to study their evolution, their selection, and use them as a cosmological probe. The offsets between different defini…
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…
XMM-Newton and SRG/eROSITA observations of the isolated neutron star candidate 4XMM J022141.5-735632
Adriana M. Pires, Christian Motch, Jan Kurpas +11
We report the results of follow-up investigations of a possible new thermally emitting isolated neutron star (INS), 4XMM J022141.5-735632, using observations from XMM-Newton and Sp…
Detecting clusters of galaxies and active galactic nuclei in an eROSITA all-sky survey digital twin
R. Seppi, J. Comparat, E. Bulbul +15
The extended ROentgen Survey with an Imaging Telescope Array (eROSITA) onboard the Spectrum-Roentgen-Gamma (SRG) observatory is revolutionizing X-ray astronomy. It provides large s…
A study of 1000 galaxies with unusually young and massive stars in the SDSS: a search for hidden black holes
Guinevere Kauffmann, Claudia Maraston, Johan Comparat +1
We select 1076 galaxies with extinction-corrected Halpha equivalent widths too large to be explained with a Kroupa (2001) IMF, and compare these with a control sample of galaxies t…
The MaNGA FIREFLY Value-Added-Catalogue: resolved stellar populations of 10,010 nearby galaxies
Justus Neumann, Daniel Thomas, Claudia Maraston +14
We present the MaNGA FIREFLY Value-Added-Catalogue (VAC) - a catalogue of ~3.7 million spatially resolved stellar population properties across 10,010 nearby galaxies from the final…
The Seventeenth Data Release of the Sloan Digital Sky Surveys: Complete Release of MaNGA, MaStar and APOGEE-2 Data
Abdurro'uf, Katherine Accetta, Conny Aerts +337
This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the complete…
The eROSITA Final Equatorial Depth Survey (eFEDS): X-ray emission around star-forming and quiescent galaxies at
Johan Comparat, Nhut Truong, Andrea Merloni +21
We aim at characterizing the hot phase of the Circum-Galactic Medium in a large sample of galaxies. We stack X-ray events from the SRG/eROSITA eFEDS survey around central galaxies…
