ALMA and JWST Identification of Faint Dusty Star-Forming Galaxies up to z~8
Jorge A. Zavala, Andreas L. Faisst, Manuel Aravena +44
We exploit a new sample of around 400 bright dusty galaxies from the ALMA CHAMPS Large Program, together with the rich JWST multi-band data products in the COSMOS field, to explore…
Little red dot variability over a century reveals black hole envelope via a giant Einstein cross
Zijian Zhang, Mingyu Li, Masamune Oguri +79
"Little red dots" (LRDs) represent a new population of astronomical objects uncovered by JWST whose nature remains debated. Although many LRDs are suspected as active galactic nucl…
A Deep Chandra X-ray Survey of a Luminous Quasar Sample at 7
Xiangyu Jin, Feige Wang, Jinyi Yang +11
We present new Chandra observations of seven luminous quasars at . Combined with archival Chandra observations of all other known quasars, they form nearly complete X-ray ob…
Discovery of two little red dots transitioning into quasars
Shuqi Fu, Zijian Zhang, Danyang Jiang +9
James Webb Space Telescope (JWST) has uncovered a new population of compact objects that show a unique V-shaped spectral energy distribution (SED) in the UV and optical wavelength…
COSMOS-3D: Dense Circumnuclear Gas across Black Hole Growth Phases at z ~ 3
Zi-Jian Li, Siwei Zou, Jianwei Lyu +25
We report the discovery of two broad-line X-ray AGNs (cid_414 and cid_947) at z ~ 3 identified in the JWST Cycle 3 COSMOS-3D program using NIRCam F444W grism spectroscopy. Both exh…
A Super-Eddington, Lensing-Magnified Quasar at observed with JWST
Katherine Panebianco, Minghao Yue, Anna-Christina Eilers +4
We present JWST/NIRCam F070W and F480M imaging for a quasar at , J0025-0145, which is magnified by a foreground lensing galaxy. Existing Hubble Space Telescope (HST) imag…
