Unveiling the Hot Interstellar Medium in Nearby Galaxies with eROSITA

Roman Laktionov, Manami Sasaki, Elias Kyritsis +9

Diffuse X-ray emission in galaxies originates from stellar-feedback-heated gas and unresolved compact sources. We investigate its thermal component and the scaling of X-ray luminos…

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…

Tracking down the broadband polarimetric properties of PG 1553+113

Riccardo Middei, Svetlana G. Jorstad, Alan P. Marscher +78

We report on a nine-month monitoring campaign of the blazar PG 1553+113, relying on three observations carried out in 2025 with the Imaging X-ray Polarimetry Explorer (IXPE) and su…

A Changing-Look Seyfert Discovered by eROSITA Reveals a Two-Component Broad-Line Region

Alex Markowitz, Mirko Krumpe, David Homan +12

Extreme sudden changes in the flow of accreting gas onto SMBHs manifest themselves via large-amplitude continuum variability and changes to broad Balmer emission profiles, driving…

BLAZ4R and the eROSITA view of z>4 blazars

Tullia Sbarrato, Silvia Belladitta, Julien Wolf +8

We present BLAZ4R, the first living catalog of confirmed blazars, with a focus on the contribution of eROSITA, on board of the Spectrum Roentgen Gamma (SRG) spacecraft. Blaza…

Rapid jet ejection from PKS 0215+015 coincident with a high-energy neutrino event

F. Eppel, M. Kadler, E. Ros +19

Aims. We present a new neutrino-blazar multiwavelength flare coincidence observed in the blazar PKS 0215+015, which showed a strong multiwavelength outburst in coincidence with the…
