Ultraluminous X-ray sources in the first eROSITA survey I. Candidate catalogs
P. Weber, T. P. Roberts, S. Hämmerich +28
Ultraluminous X-ray sources (ULXs) are luminous non-nuclear X-ray point sources embedded in galaxies. Their luminosities exceeding 10^39 erg/s potentially require sub-Eddington acc…

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…

Low-hard to high-soft spectral state transitions in the faintest early-X-ray-detected optical tidal disruption event TDE 2025aarm
Pietro Baldini, Arne Rau, Andrea Merloni +11
The paper presents X‑ray and optical spectroscopic observations of the nearby tidal disruption event TDE 2025aarm, revealing a low‑hard to high‑soft spectral state transition that…
