Hidden Monsters with SPHEREx I: A goldmine for heavily reddened quasars at cosmic noon
Matthew Stepney, Manda Banerji, Franz E. Bauer +2
Heavily reddened quasars (HRQs) are luminous, dust-obscured broad-line quasars thought to represent a short-lived phase of intense black hole growth and feedback. Previous studies…
A Deep Study of the Spiral Galaxy W2246f
Evelyn J. Johnston, Sorya Lambert, Aparna Nair +10
In this era of large surveys and statistical studies of galaxies, the beauty in the details of individual galaxies is often lost. We present a deep study of the spiral galaxy W2246…
VAR-PZ: Constraining the Photometric Redshifts of Quasars using Variability
S. Satheesh-Sheeba, R. J. Assef, T. Anguita +33
The Vera C. Rubin Observatory LSST is expected to discover tens of millions of new Active Galactic Nuclei (AGNs). The survey's exceptional cadence and sensitivity will enable UV/op…
AGN Variability with Rubin Observatory in the 2030s
Swayamtrupta Panda, Francisco Pozo Nuñez, Hygor Benati Gonçalves +4
AGN variability offers a direct probe of accretion physics, disk structure, and black hole growth, but progress has been limited by sample size, cadence heterogeneity, and photomet…
Evidence of Gas Depletion in Quasars with Moderate Radio Emission
Yuhan Wen, Ran Wang, Luis C. Ho +4
The energy released by active galactic nuclei (AGNs) is considered to have a profound impact on the cold gas properties of their host galaxies, potentially heating or removing the…
Predicting Quasar Counts Detectable in the LSST Survey
Guodong Li, Roberto J. Assef, W. N. Brandt +11
The Legacy Survey of Space and Time (LSST), being conducted by the Vera C. Rubin Observatory, is a wide-field multi-band survey that will revolutionize our understanding of extraga…
