Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations

Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121

Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…

A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ~ 12 Galaxy in Early JWST CEERS Imaging

Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +117

We report the discovery of a candidate galaxy with a photo-z of z~12 in the first epoch of the JWST Cosmic Evolution Early Release Science (CEERS) Survey. Following conservative se…

Hamilton's Object -- a clumpy galaxy straddling the gravitational caustic of a galaxy cluster : Constraints on dark matter clumping

Richard E. Griffiths, Mitchell Rudisel, Jenny Wagner +3

We report the discovery of a 'folded' gravitationally lensed image, 'Hamilton's Object', found in a HST image of the field near the AGN SDSS J223010.47-081017.8 (). The len…

Observations of the gamma-ray emitting narrow-line Seyfert 1, SBS 0846+513, and its host galaxy

Timothy S. Hamilton, Marco Berton, Sonia Antón +9

The gamma-ray emitting galaxy SBS 0846+513 has been classified as a Narrow-Line Seyfert 1 from its spectroscopy, and on that basis it was thought likely to have a small central bla…

The host galaxies of FeLoBAL quasars at z0.9 are not dominated by recent major mergers

C. Villforth, H. Herbst, F. Hamann +4

Theoretical models have suggested an evolutionary model for quasars, in which most of luminous quasars are triggered by major mergers. It is also postulated that reddening as well…

Host galaxies of luminous z0.6 quasars: Major mergers are not prevalent at the highest AGN luminosities

C. Villforth, T. Hamilton, M. M. Pawlik +10

Galaxy interactions are thought to be one of the main triggers of Active Galactic Nuclei (AGN), especially at high luminosities, where the accreted gas mass during the AGN lifetime…
