SRG/eROSITA X-ray selected cataclysmic variable candidates observed in SDSS-V DR20
J. Brink, A. D. Schwope, K. G. Pradeep +35
The paper presents spectroscopic observations from SDSS‑V of cataclysmic variable candidates identified via X‑ray detections in the SRG/eROSITA eRASS1 and eRASS3 surveys, assemblin…
The eROSITA X-ray luminosity function of active galactic nuclei
W. Roster, J. Buchner, M. Salvato +23
The paper measures the soft X‑ray luminosity function of active galactic nuclei using eROSITA data across a wide luminosity and redshift range, introduces a redshift‑dependent brok…
The incidence of eROSITA X-ray AGN in the local Universe: from dwarf to massive galaxies
Z. Igo, A. Merloni, A. Georgakakis +22
Combining deep, wide-area X-ray surveys with multi-wavelength catalogues provides insights into rare, highly-accreting AGN and low-mass galaxies at low redshift, the latter potenti…
The Curious Case of PHL 1811: Heavy Obscuration Versus Intrinsic X-ray Weakness
B. Luo, Xiaolei Chen, Jian Huang +2
We present a systematic X-ray analysis of the narrow-line Type 1 quasar PHL 1811, which has long been regarded as the prototype of intrinsically X-ray weak quasars. A critical brea…
SDSS-V Black Hole Mapper: The Index Diagram as a tool to disentangle the influence of the Host Galaxy in Quasar spectra
C. A. Negrete, R. Sandoval-Orozco, H. Ibarra-Medel +32
We revisit the Quasar Main Sequence (QMS) by investigating the impact of the stellar component from the host galaxy (HG) on the emission line spectra of the active galactic nuclei…
The Compton-thick AGN Population and the Distribution of Low-mass AGN in our Cosmic Backyard
A. Annuar, D. M. Alexander, P. Gandhi +21
We present a census of the Compton-thick (CT) active galactic nucleus (AGN) population and the column density () distribution of AGN in our cosmic backyard using a mid-…
