A Census of the 200 Most Massive Galaxies Spectroscopically Observed with JWST at zspec 3-15
Mengyuan Xiao, Pascal A. Oesch, Longji Bing +26
Massive galaxies provide strong tests of galaxy formation models, yet a comprehensive spectroscopic view of their properties and demographics in the early Universe has remained elu…
A Pixel-by-Pixel Path to Population III Discovery with JWST
Patricia Iglesias-Navarro, Thomas Harvey, Marc Huertas-Company +11
The identification of the first generation of metal-free stars, known as Population III (Pop~III), remains a primary goal of modern observational astronomy. While JWST has discover…
Extended [CII] gas emission in and around a massive quiescent galaxy at z=7.3
F. Valentino, A. Pensabene, A. Weibel +16
We report the discovery of [CII] 158 micron emission in and around the most distant known massive quiescent galaxy RUBIES-UDS-QG-z7 at z = 7.27. Observed with ALMA in band 6, the […
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…
Beyond the Dot: an LRD-like nucleus at the Heart of an IR-Bright Galaxy and its implications for high-redshift LRDs
Pierluigi Rinaldi, George H. Rieke, Zihao Wu +23
Little Red Dots (LRDs) are compact, red sources discovered by JWST at high redshift (), marked by distinctive 'V-shaped' spectral energy distributions (SEDs) and often…
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…
