Quasar Impostors: Two Extremely UV-Bright () Reionisation-Epoch Galaxies Powered by Very Massive Stars
Daming Yang, Joseph F. Hennawi, Sarah E. I. Bosman +20
The extreme bright end of the galaxy UV luminosity function during reionisation remains poorly constrained, particularly where the galaxy and quasar luminosity functions overlap an…
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…
JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases
Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23
Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…
Direct detection of cool molecular gas in a star-forming galaxy at
Karin Cescon, Jacqueline A. Hodge, Leindert A. Boogaard +21
We investigate the molecular gas content and interstellar medium (ISM) conditions of REBELS-25, a massive, star-forming galaxy at . Deep VLA Q-band and ALMA Band 3 observat…
Little Red Dot Host Galaxy Black Hole Star: A Gas-Enshrouded Heart at the Center of Every Little Red Dot
Wendy Q. Sun, Rohan P. Naidu, Jorryt Matthee +30
The central engines of Little Red Dots (LRDs) may be ``black hole stars" (BH*s), early stages of black hole growth characterized by dense gas envelopes. So far, the most direct evi…
A GLIMPSE of the 99%: a census of the faintest galaxies during the epoch of reionization and its implications for galaxy formation models
Hakim Atek, Iryna Chemerynska, Lukas J. Furtak +19
We present a comprehensive study of the galaxy UV luminosity function (UVLF) at leveraging deep JWST observations from the GLIMPSE survey. Thanks to gravitational lensing,…
