360. SDSS-V: Pioneering Panoptic Spectroscopy

Juna Kollmeier

Oral

The Sloan Digital Sky Survey V (SDSS-V) is pioneering panoptic spectroscopy. SDSS-V consists of three separate large-scale surveys: 1) Black Hole Mapper (BHM) will trace the growth physics of black holes across the Universe, 2) Milky Way Mapper (MWM) is designed to decode the chemo-dynamical history of the Galaxy and investigate fundamental issues in stellar physics, and 3) the Local Volume...

350. AGN X-ray / Multi-wavelength Surveys Review

Franz Bauer (Universidad Católica de Chile)

Oral

Over the past few decades, multi-wavelength surveys have revolutionized our understanding of active galactic nuclei (AGN) demography, structure, physics, host galaxies and host/AGN co-evolution. Wide-field and deep X-rays and mid-infrared constraints have been particularly essential in this regard as a means to peer through the substantial dust obscuration that surrounds most strongly...

320. X-ray beacons at late cosmic dawn

Oral

From extrapolations of contemporaneous X-ray active galactic nuclei (AGN) luminosity functions, the eROSITA all-Sky Survey (eRASS) is expected to contain ~100 X-ray ultra-luminous quasars, that emitted their light when the universe was less than a billion years old, at z>5.6. In the luminosity regime probed by eROSITA at these early times, the powerful X-ray output of these quasars is driven...

330. An X-Ray Census of Active Galactic Nuclei in the Virgo and Fornax Clusters of Galaxies with SRG/eROSITA

Meicun Hou (Kavli Institute for Astronomy and Astrophysics, Peking University)

9/16/24, 12:30 PM

Oral

We present a uniform and sensitive X-ray census of active galactic nuclei (AGNs) in the two nearest galaxy clusters, Virgo and Fornax, utilizing the newly released X-ray source catalogs from the first all-sky scan of Spectrum-Roentgen-Gamma/eROSITA. A total of 50 and 10 X-ray sources are found positionally coincident with the nuclei of member galaxies in Virgo and Fornax, respectively, down to...
