O Corona, where art thou? eROSITA's view of UV-optical-IR variability-selected massive black holes in low-mass galaxies
R. Arcodia, A. Merloni, J. Comparat +16
Finding massive black holes (MBHs, ) in the nuclei of low-mass galaxies () is crucial to constrain seeding and…
A study of 1000 galaxies with unusually young and massive stars in the SDSS: a search for hidden black holes
Guinevere Kauffmann, Claudia Maraston, Johan Comparat +1
We select 1076 galaxies with extinction-corrected Halpha equivalent widths too large to be explained with a Kroupa (2001) IMF, and compare these with a control sample of galaxies t…
First constraints on the AGN X-ray luminosity function at from an eROSITA-detected quasar
Julien Wolf, Kirpal Nandra, Mara Salvato +19
We searched for high-z quasars within the X-ray source population detected in the contiguous eFEDS field observed by eROSITA during the performance verification phase.…
The Sloan Digital Sky Survey Quasar Catalog: Sixteenth Data Release
Brad W. Lyke, Alexandra N. Higley, J. N. McLane +34
We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog compris…
SPIDERS: overview of the X-ray galaxy cluster follow-up and the final spectroscopic data release
N. Clerc, C. C. Kirkpatrick, A. Finoguenov +19
SPIDERS (The SPectroscopic IDentification of eROSITA Sources) is a large spectroscopic programme for X-ray selected galaxy clusters as part of the Sloan Digital Sky Survey-IV (SDSS…
The final SDSS-IV/SPIDERS X-ray point source spectroscopic catalogue
J. Comparat, A. Merloni, T. Dwelly +15
We look to provide a detailed description of the SPectroscopic IDentification of ERosita Sources (SPIDERS) survey, an SDSS-IV programme aimed at obtaining spectroscopic classificat…
