Euclid: Discovery of 31 new quasars at

D. Yang, J. F. Hennawi, F. Guarneri +211

We report the discovery of 31 new high- quasars in the redshift range . These quasars were selected from approximately 3000 deg of sky covered during the firs…

HST's Deep Blue: extremely deep UV imaging to reveal the contributors to reionization

Ilias Goovaerts, Alexander Beckett, Matthew Hayes +12

Understanding galaxy evolution in the epoch of reionization and the effect these galaxies had on the transformation of the intergalactic medium from neutral to ionized, is a key go…

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,…

Owl-z: a Bayesian tool to select z \geq 7 quasars

Meriam Ezziati, Roser Pello, Jean-Gabriel Cuby +9

This paper presents Owl-z, a Bayesian code aiming at identifying z \geq 7 quasars in wide field optical and near-infrared surveys. By construction,the code can also be used to sele…

JWST's GLIMPSE: an overview of the deepest probe of early galaxy formation and cosmic reionization

Hakim Atek, John Chisholm, Vasily Kokorev +44

We present an overview of the JWST GLIMPSE program, highlighting its survey design, primary science goals, gravitational lensing models, and first results. GLIMPSE provides ultra-d…

Euclid: The potential of slitless infrared spectroscopy: A z=5.4 quasar and new ultracool dwarfs

E. Bañados, V. Le Brun, S. Belladitta +226

We demonstrate the potential of Euclid's slitless spectroscopy to discover high-redshift (z>5) quasars and their main photometric contaminant, ultracool dwarfs. Sensitive infrared…
