Discovery of the Lyman- Forest in a Star-Forming Galaxy at : Implications for the Timing and Topology of Cosmic Reionization
Jakob M. Helton, Joris Witstok, Marta Laska +15
The escape of ionizing photons from galaxies during the Epoch of Reionization is often inferred indirectly because the intervening neutral hydrogen in the intergalactic medium (IGM…
Gone with the wind? Potential gas inflow in the broad-line region of a QSO at traced by time-varying Balmer absorption
Xihan Ji, Dominic J. Walton, Francesco D'Eugenio +6
We report spectroscopic observations of a remarkable QSO, J115724.80-000455.56 at from the Dark Energy Spectroscopic Instrument (DESI) survey. This QSO exhibits variabili…
The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
A Dusty Quenching-candidate AGN host at z=5.7: massive quiescent galaxies may quench already during the dust-obscured phase
Francesco D'Eugenio, Matilde Brazzini, Roberto Maiolino +12
We present a spectro-photometric analysis of RUBIES-EGS-9809, a broad-line AGN host at z=5.7 with a Balmer break and a dominant point source. The source is dust reddened (3 m…
Misaligned or chaotic? A strong break of axial symmetry in the local LRD J1025 revealed with VLT/FORS2 spectropolarimetry
Francesco D'Eugenio, Gabriele Pezzulli, Roberto Maiolino +18
Little Red Dots (LRDs) are compact active galactic nuclei (AGN) with unusual spectral energy distributions and broad Balmer emission, candidate signposts of rapid black-hole growth…
How to raise a supermassive black hole: interpreting early JWST AGN with the AESOPICA simulations
Sophie Koudmani, Jan Scholtz, Anthony J. Taylor +11
The active black holes uncovered by JWST in the early Universe are highly abundant and seemingly overmassive with respect to local scaling relations, challenging standard models of…
A quasar hatching from a buried red phase at z = 3.7
Zheng Ma, Yongda Zhu, Zhiyuan Ji +21
We present JADES-GS 209777, previously cataloged as CANDELS J033238.02-274626.2, hereafter "the Hatchling," a red quasar at . While the source has been reported in earlier…
An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN -- radiation-driven outflows in little red dots, quasars and variable stars
Ignas Juodžbalis, Xihan Ji, Francesco D'Eugenio +17
A notable achievement of the first generation of JWST surveys was the discovery of an abundance of faint high-redshift () broad-line active galactic nuclei (AGN) in the $L_{…
A Steep-Extinction Quasi-stellar Object at z=4.6: JWST Evidence for Abundant Small Dust Grains
Mingyu Li, Zheng Cai, Roberto Maiolino +9
The rapid accumulation of massive dust reservoirs in the early Universe remains a major challenge in astrophysics. While core-collapse supernovae can inject large dust grains ($a \…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +18
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
Undermassive Hosts of AGN from JWST/NIRCam Image Decomposition with CONGRESS, FRESCO, and JADES
Zheng Ma, Eichi Egami, Yongda Zhu +18
In the local Universe, supermassive black hole (SMBH) masses strongly correlate with their host-galaxies' stellar masses (), but galaxies hosting faint AGN recently found by…
