Luminous Mid-IR Selected Obscured Quasars at Cosmic Noon in SDSS Stripe82 II: Spectroscopic Diversity and Broad H Emissions
Ben Wang, Yuzo Ishikawa, Joseph F. Hennawi +5
We present a multiwavelength spectroscopic survey of 23 luminous mid-infrared-selected Type-2 quasars at redshifts z = 0.88 to 3.49. The targets were selected in the SDSS Stripe 82…
JWST IFU observations uncover host galaxy continua in extremely red and obscured quasars
Yu-Ching Chen, Nadia L. Zakamska, Andrey Vayner +9
Uncovering bright quasars' host galaxies at cosmic noon is challenging because of the high contrast between the quasar and its host and redshifted light, making them primarily visi…
Galactic-scale Quasar Pairs from the Sloan Digital Sky Survey and Gaia DR3
Yuanzhe Jiang, Yue Shen, Xin Liu +6
We preform a systematic search for galactic-scale quasar pairs and small-scale (<3 arcsec) lenses using the SDSS DR16 quasar catalog and Gaia DR3. Candidate double quasars (both ar…
VODKA: Complex molecular gas dynamics in a kpc-separation z=2.17 dual quasar with ALMA
Yuzo Ishikawa, Nadia L. Zakamska, Yu-Ching Chen +6
In galaxy mergers, dual quasars - two actively accreting supermassive black holes (SMBHs) - provide a unique opportunity to study the interplay between galaxy dynamics and quasar a…
Luminous Mid-IR Selected Type-2 Quasars at Cosmic Noon in SDSS Stripe82 I: Selection, Composite Photometry, and Spectral Energy Distributions
Ben Wang, Joseph F. Hennawi, Zheng Cai +6
We analyze 23 spectroscopically confirmed Type-2 quasars (QSOs) selected from the WISE 22m band in the SDSS Stripe 82 region, focusing on their multi-band photometry and spe…
