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…

Two Peas in a Pod: The First Confirmed Dual Active Galactic Nucleus within a Green Pea Galaxy System

Konstantinos Kouroumpatzakis, Peter G. Boorman, Jiří Svoboda +5

The growth of galaxies in the early Universe is thought to be dominated by compact, intensely star-forming systems, yet the corresponding growth of supermassive black holes (SMBHs)…

Spectroscopic redshifts of selected flat-spectrum radio sources I

Dmitry Blinov, Alberto Floris, Andreas Zezas +5

We present the first results of a spectroscopic campaign carried out as part of the Search for Milli-Lenses (SMILE) program, which aims to constrain the prevalence of gravitational…

Mid-Infrared diagnostics for identifying main sequence galaxies in the local Universe

C. Daoutis, A. Zezas, M. L. N. Ashby

A galaxy's mid-IR spectrum encodes key information on its radiation field, star formation, and dust properties. Characterizing this spectrum therefore offers strong constraints on…

From seagull to hummingbird: New diagnostic methods for resolving galaxy activity

C. Daoutis, A. Zezas, E. Kyritsis +2

Context. A major challenge in astrophysics is classifying galaxies by their activity. Current methods often require multiple diagnostics to capture the full range of galactic activ…

X-ray observations of Blueberry galaxies

B. Adamcová, J. Svoboda, E. Kyritsis +7

Compact star-forming galaxies were dominant galaxy types in the early Universe. Blueberry galaxies (BBs) represent their local analogues being very compact and having intensive sta…
