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…

Variability of Central Stars of Planetary Nebulae with the Zwicky Transient Facility. I. Methods, Short-Timescale Variables, Binary Candidates, and the Unusual Nucleus of WeSb 1

Soumyadeep Bhattacharjee, S. R. Kulkarni, Albert K. H. Kong +16

Over the past several decades, time-series photometry of CSPNe has yielded significant results including, but not limited to, discoveries of nearly 100 binary systems, insights int…

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…

The companion mass distribution of post common envelope hot subdwarf binaries: evidence for boosted and disrupted magnetic braking?

Lisa Blomberg, Kareem El-Badry, Katelyn Breivik +6

We measure the mass distribution of main-sequence (MS) companions to hot subdwarf B stars (sdBs) in post-common envelope binaries (PCEBs). We carried out a spectroscopic survey of…

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…
