An Investigation Into The Selection and Colors of Little Red Dots and Active Galactic Nuclei
Kevin N. Hainline, Roberto Maiolino, Ignas Juodzbalis +25
Recently, a large number of compact sources at with blue UV slopes and extremely red rest-frame optical slopes have been found in James Webb Space Telescope (JWST) extragal…
Episodic super-Eddington accretion as a clue to Overmassive Black Holes in the early Universe
Alessandro Trinca, Rosa Valiante, Raffaella Schneider +7
Early JWST observations are providing growing evidence for a ubiquitous population of accreting supermassive black holes (BHs) at high redshift, many of which appear overmassive co…
EPOCHS I. The Discovery and Star Forming Properties of Galaxies in the Epoch of Reionization at with PEARLS and Public JWST data
Christopher J. Conselice, Nathan Adams, Thomas Harvey +32
We present in this paper the discovery, properties, and a catalog of 1165 high redshift galaxies found in deep JWST NIRCam imaging from the GTO PEARLS survey combine…
JADES: Spectroscopic Confirmation and Proper Motion for a T-Dwarf at 2 Kiloparsecs
Kevin N. Hainline, Francesco D'Eugenio, Fengwu Sun +15
Large area observations of extragalactic deep fields with the James Webb Space Telescope (JWST) have provided a wealth of candidate low-mass L- and T-class brown dwarfs. The existe…
JADES -- The Rosetta Stone of JWST-discovered AGN: deciphering the intriguing nature of early AGN
Ignas Juodžbalis, Xihan Ji, Roberto Maiolino +23
JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H), but are ext…
JWST meets Chandra: a large population of Compton thick, feedback-free, and intrinsically X-ray weak AGN, with a sprinkle of SNe
Roberto Maiolino, Guido Risaliti, Matilde Signorini +22
We investigate the X-ray properties of a sample of 71 broad line and narrow line AGN at 2z11 discovered by JWST in the GOODS fields, which have the deepest Chandra observatio…
The Host Galaxy of a Dormant, Overmassive Black Hole at May Be Restarting Star Formation
Fabio Pacucci, Abraham Loeb, Ignas Juodžbalis
JWST is discovering a large population of supermassive black holes (SMBHs) that are overmassive with respect to the stellar content of their hosts. A previous study developed…
EPOCHS III: Unbiased UV continuum slopes at 6.5<z<13 from combined PEARLS GTO and public JWST NIRCam imaging
Duncan Austin, Christopher J. Conselice, Nathan J. Adams +34
We present an analysis of rest-frame UV continuum slopes, , using a sample of 1011 galaxies at from the EPOCHS photometric sample collated from the GTO PEARLS and pub…
EPOCHS IV: SED Modelling Assumptions and their impact on the Stellar Mass Function at 6.5 < z < 13.5 using PEARLS and public JWST observations
Thomas Harvey, Christopher J. Conselice, Nathan J. Adams +31
We utilize deep JWST NIRCam observations for the first direct constraints on the Galaxy Stellar Mass Function (GSMF) at . Our EPOCHS v1 sample includes 1120 galaxy candidates…
A dormant, overmassive black hole in the early Universe
Ignas Juodžbalis, Roberto Maiolino, William M. Baker +25
Recent observations have found a large number of supermassive black holes already in place in the first few hundred million years after Big Bang. The channels of formation and grow…
