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…

Frequency and Abundance of Binary sUpermassive bLack holes from Optical Variability Surveys (FABULOVS): Hubble Space Telescope Imaging of Radial-Velocity Selected Binary Candidates
Liam Nolan, Ming-Yang Zhuang, Xin Liu +4
Sub-parsec (sub-pc) binary supermassive black holes (BSBHs) should be common from galaxy mergers, yet direct evidence has been elusive. We present HST/WFC3IR F160W imaging for a sa…

VODKA-JWST: A 3.8 kpc dual quasar at cosmic noon in a powerful starburst galaxy with JWST/MIRI IFU
Yu-Ching Chen, Yuzo Ishikawa, Nadia L. Zakamska +12
Dual quasars, two active supermassive black holes at galactic scales, represent crucial objects for studying the impact of galaxy mergers and quasar activity on the star formation…
