Exploring Cosmic Dawn with PANORAMIC II: Cosmic Variance and Galaxy Clustering at
Andrea Weibel, Christian Kragh Jespersen, Pascal A. Oesch +10
Observational campaigns with JWST have revealed a higher-than-expected abundance of UV-bright galaxies at , with various proposed theoretical explanations. A powerful c…
Compact Core, Extended Reach: A Bipolar kpc-Scale Elongation in a Little Red Dot at
Zhiyuan Ji, Yang Sun, Mauro Giavalisco +7
Little Red Dots (LRDs) appear extremely compact at rest-frame optical wavelengths, yet many show extended rest-frame UV morphology revealing more complex internal structure. We pre…
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…
Through the Veil: Ly Illuminates the Host Galaxies of Little Red Dots
Zhiyuan Ji, Yang Sun, Mauro Giavalisco +5
Little Red Dots (LRDs) are enigmatic, compact red sources ubiquitous in JWST deep fields whose physical nature remains elusive. As one of the most sensitive tracers of neutral hydr…
Exploring Cosmic Dawn with PANORAMIC I: The Bright End of the UVLF at
Andrea Weibel, Pascal A. Oesch, Christina C. Williams +14
In its first two years of operation, the James Webb Space Telescope has enabled the discovery of a surprising number of UV-bright galaxies at . Their number density is…
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…
