Reionization driven by the few: the ionizing budget of galaxies at z=5-10 from JWST/NIRSpec
Emma Giovinazzo, Pascal A. Oesch, Anne Verhamme +5
The sources responsible for the Epoch of Reionization (EoR), the last major phase transition of the Universe, remain highly elusive. While JWST has begun to illuminate the properti…
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…
Chemical signatures from the first stars embedded in metal-poor gas in galaxies at cosmic dawn
Clara L. Pollock, Kasper E. Heintz, Elka Rusta +15
The first generation of stars formed from pristine, neutral hydrogen gas. The most massive of these exploded as supernovae within a few million years of their birth, producing the…
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…
Too many protoclusters? Reconciling the overabundance of cluster progenitors within the first billion years of the Universe
Callum Witten, Jake S. Bennett, Pascal A. Oesch +8
JWST has revealed an overabundance of apparent (`Coma'-like) cluster progenitors at that is two (300) times in excess of, and in () tension with, the number…
Life After the Quasar: Overmassive Black Holes and Remnant Ionised Bubbles in and Around Two z~6.6 Galaxies
Romain A. Meyer, Pascal A. Oesch, Callum Witten +7
Supermassive black holes (SMBH, ) powering luminous quasars already exist one billion years after the Big Bang, yet their connection to their star-formi…
