Black Hole Stars Across the Universe: Identifying Central Engine Dominated Little Red Dots at
Andrea Weibel, Rohan P. Naidu, Pascal A. Oesch +16
Photometric selections of Little Red Dots (LRDs) largely rely on identifying their ``V-shaped'' spectral energy distribution (SED). Recent work suggests this V-shape stems from a c…
DeepDive: Simultaneous Formation of Massive Quiescent Galaxies in High-Redshift Galaxy Overdensities
Takumi Kakimoto, Masayuki Tanaka, Kei Ito +20
We report on the spectroscopic confirmation of overdense regions of massive quiescent galaxies (QGs) in the early Universe with JWST/NIRSpec. Based on data from the DeepDive NIRSpe…
Winding Back the Clock: Recent Star Formation Histories of Massive Quiescent Galaxies Are Consistent With Their Rapid Number Density Evolution Since
Yunchong Zhang, Zhiyuan Ji, Rachel Bezanson +17
Massive quiescent galaxies have been identified out to in early JWST data in a substantial excess ( at ) of number densities from most theoretical…
PANORAMIC: The Dawn of Massive Quiescent Galaxies I. Number Density and Cosmic Variance from 1000 arcmin NIRCam Imaging
Zhiyuan Ji, Christina C. Williams, Peter Behroozi +13
We measure the number density and field-to-field variance of massive quiescent galaxies at - 8 using the JWST/NIRCam pure-parallel imaging survey PANORAMIC together with a…
A PANORAMIC of UV-optical morphologies of "Little Red Dots": Two groups of LRDs distinguished by UV half-light radius
Aidan P. Cloonan, Katherine E. Whitaker, Sinclaire M. Manning +13
Among the most remarkable results from JWST is the discovery of abundant, compact, and very red sources in the early Universe known as "Little Red Dots" (LRDs). The relative degree…
A Black Hole Star at Cosmic Noon: Extreme Balmer break, photospheric continuum, and broad absorption by thick winds in a Little Red Dot at z=1.7
Alberto Torralba, Jorryt Matthee, Andrea Weibel +12
Recent studies at high redshift have revealed an enigmatic class of Little Red Dots (LRDs) with extreme Balmer breaks, stronger than in any stellar atmosphere. However, it is uncle…
The ionised interstellar medium of DSFGs revealed by JWST/NIRSpec and ALMA: Super-solar metallicity, low ionisation parameters and, typical electron densities
Steven Gillman, Kei Ito, Francesco Valentino +25
We present a detailed study of near-infrared (2-4m) JWST/NIRSpec spectra of 48 high-redshift () galaxies detected with ALMA at . From a multi-wa…
DeepDive: Tracing the early quenching pathways of massive quiescent galaxies at from their star-formation histories and chemical abundances
Massissilia L. Hamadouche, Katherine E. Whitaker, Francesco Valentino +21
We investigate the chemical abundances and star-formation histories (SFH) of ten massive () quiescent galaxies at usi…
There and back again? Neutral outflows in z~3.5 quiescent galaxies
Pengpei Zhu, Kei Ito, Francesco Valentino +16
Neutral gas outflows play a crucial role in the baryon cycle of galaxies, their properties provide key insights into the transition from star formation to quiescence. In this work,…
