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…

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…

Towards Unbreaking the Universe: MINERVA Measurements of Color Gradients in Massive Quiescent Galaxies Can Help Ease Too-Early Star Formation Tensions

Sam E. Cutler, Luke Robbins, Danilo Marchesini +41

The discovery of a population of massive, ancient quiescent galaxies within the first 2 Gyr of the Universe's history has led to significant tensions with models of galaxy formatio…

A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST

Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43

JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…

REBELS-IFU: Dust Build-up in Massive Galaxies at Redshift 7

Hiddo Algera, Lucie Rowland, Mauro Stefanon +22

In recent years, observations with the JWST have started to map out the rapid metal enrichment of the early Universe, while (sub)millimeter observations have simultaneously begun t…
