Black hole jets on the scale of the Cosmic Web

Martijn S. S. L. Oei, Martin J. Hardcastle, Roland Timmerman +10

Jets launched by supermassive black holes transport relativistic leptons, magnetic fields, and atomic nuclei from the centres of galaxies to their outskirts and beyond. These outfl…

Cataclysmic Variables and AM CVn Binaries in SRG/eROSITA + Gaia: Volume Limited Samples, X-ray Luminosity Functions, and Space Densities

Antonio C. Rodriguez, Kareem El-Badry, Valery Suleimanov +22

We present volume-limited samples of cataclysmic variables (CVs) and AM CVn binaries jointly selected from SRG/eROSITA eRASS1 and \textit{Gaia} DR3 using an X-ray + optical color-c…

Searching for New Cataclysmic Variables in the Chandra Source Catalog

Ilkham Galiullin, Antonio C. Rodriguez, Kareem El-Badry +14

Cataclysmic variables (CVs) are compact binary systems in which a white dwarf accretes matter from a Roche-lobe-filling companion star. In this study, we searched for new CVs in th…

A Joint SRG/eROSITA + ZTF Search: Discovery of a 97-min Period Eclipsing Cataclysmic Variable with Evidence of a Brown Dwarf Secondary

Ilkham Galiullin, Antonio C. Rodriguez, Shrinivas R. Kulkarni +24

Cataclysmic variables (CVs) that have evolved past the period minimum during their lifetimes are predicted to be systems with a brown dwarf donor. While population synthesis models…

No X-Rays or Radio from the Nearest Black Holes and Implications for Future Searches

Antonio C. Rodriguez, Yvette Cendes, Kareem El-Badry +1

Astrometry from the Gaia mission was recently used to discover the two nearest known stellar-mass black holes (BHs), Gaia BH1 and Gaia BH2. Both systems contain …

SRGeJ045359.9+622444: A 55-min Period Eclipsing AM CVn Discovered from a Joint SRG/eROSITA + ZTF Search

Antonio C. Rodriguez, Ilkham Galiullin, Marat Gilfanov +24

AM CVn systems are ultra-compact binaries where a white dwarf accretes from a helium-rich degenerate or semi-degenerate donor. Some AM CVn systems will be among the loudest sources…

A very luminous jet from the disruption of a star by a massive black hole

Igor Andreoni, Michael W. Coughlin, Daniel A. Perley +78

Tidal disruption events (TDEs) are bursts of electromagnetic energy released when supermassive black holes (SMBHs) at the centers of galaxies violently disrupt a star that passes t…

Discovery of Two Polars from a Crossmatch of ZTF and the SRG/eFEDS X-ray Catalog

Antonio C. Rodriguez, Shrinivas R. Kulkarni, Thomas A. Prince +14

Magnetic CVs are luminous Galactic X-ray sources but have been difficult to find in purely optical surveys due to their lack of outburst behavior. The eROSITA telescope aboard the…

The Search for a Counterpart to NuSTAR J053449+2126.0

Antonio C. Rodriguez, Yuhan Yao, Kishalay De +1

Tumer et al. 2022, ATel #15171, have recently reported the discovery of an X-ray source, NuSTAR J053449+2126.0, during a calibration observation which took place on 25 April 2020.…
