The dawn of the first galaxies
Livia Vallini, Tanio Diaz Santos, Belen Alcalde Pampliega +56
Understanding how the first galaxies assembled their stellar mass at cosmic dawn is a central frontier of modern astrophysics. JWST has now revealed an unexpected population of ult…
The metallicities of little red dot host galaxies: LRDs are metal poor, but not pristine
G. P. Nikopoulos, D. Watson, C. L. Pollock +4
Little Red Dots (LRDs) are a population of high-z sources discovered by JWST whose compactness, broad permitted lines, strong absorption features, continuum shapes and luminosities…
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…
Paschen Jumps in Little Red Dots: Evidence for Nebular Continua
Albert Sneppen, James H. Matthews, Darach Watson +6
''Little Red Dots'' (LRDs) are broad-line sources at high redshift, initially identified by their compact morphologies, red colours and prominent Balmer breaks. The origin of their…
A hot, nebular-dominated galaxy interacting with a pristine PopIII system uncovered by JWST
Henriette Reumert, Kasper E. Heintz, Clara L. Pollock +6
The discovery of galaxies with extremely strong nebular continuum emission at high redshifts provide novel, unique insights into the conditions under which the first super-massive…
Emergence hour-by-hour of -process features in the kilonova AT2017gfo
Albert Sneppen, Darach Watson, Rasmus Damgaard +4
The spectral features in the optical/near-infrared counterparts of neutron star mergers (kilonovae, KNe), evolve dramatically on hour timescales. To examine the spectral evolution…
