The eROSITA X-ray luminosity function of active galactic nuclei
W. Roster, J. Buchner, M. Salvato +23
The paper measures the soft X‑ray luminosity function of active galactic nuclei using eROSITA data across a wide luminosity and redshift range, introduces a redshift‑dependent brok…
Thermal or Non-thermal? Diffuse emission in the infall region of stacked galaxy groups
E. Bulbul, X. Zhang, Z. Ding +16
The authors stack eROSITA X‑ray data for 827 low‑mass galaxy groups to detect faint diffuse emission out to ~2 R200, measuring temperature, density, and metal abundance in the infa…
The SRG/eROSITA All-Sky Survey DR2: Cumulative X-ray catalogues from the first three surveys and multi-wavelength counterparts in the western Galactic hemisphere
M. E. Ramos-Ceja, G. Lamer, M. Salvato +111
The paper presents the second data release of the SRG/eROSITA all‑sky survey, providing catalogues of nearly two million X‑ray sources (point‑like and extended) from the first thre…
Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster
R. Habas, M. Cantiello, G. Riccio +169
Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…
The incidence of eROSITA X-ray AGN in the local Universe: from dwarf to massive galaxies
Z. Igo, A. Merloni, A. Georgakakis +22
Combining deep, wide-area X-ray surveys with multi-wavelength catalogues provides insights into rare, highly-accreting AGN and low-mass galaxies at low redshift, the latter potenti…
Simulation-Based Inference for Cluster Cosmology with Set-Based Neural Network Architectures
S. Zelmer, E. Bulbul, K. Lehman +18
The unprecedented statistical power of galaxy cluster catalogs from the SRG (Spectrum Roentgen Gamma)/eROSITA All-Sky Survey provides a unique opportunity to place stringent constr…
