The slope and scatter of the star forming main sequence at z~5 : reconciling observations with simulations
Claudia Di Cesare, Jorryt Matthee, Rohan P. Naidu +17
Galaxies exhibit a tight correlation between their star-formation rate and stellar mass over a wide redshift range known as the star-forming main sequence (SFMS). With JWST, we can…
Neutral hydrogen in and around galaxies during the Epoch of Reionization
V. Gelli, C. Mason, A. Pallottini +9
JWST spectra revealing Lyman- (Ly) absorption in galaxies offer a unique probe of reionization's earliest stages. However, disentangling absorption by the increa…
Diversity and Evolution of Dust Attenuation Curves from Redshift z ~ 1 to 9
Irene Shivaei, Rohan P. Naidu, Francisco Rodriguez Montero +23
The UV-optical dust attenuation curve is key to interpreting the intrinsic properties of galaxies and provides insights into the nature of dust grains and their geometry relative t…
JWST Spectroscopic Insights Into the Diversity of Galaxies in the First 500 Myr: Short-Lived Snapshots Along a Common Evolutionary Pathway
Guido Roberts-Borsani, Pascal Oesch, Richard Ellis +21
We investigate the nature and spectroscopic diversity of early galaxies from a sample of 41 sources at z>10 with JWST/NIRSpec prism observations. We compare the properties of stron…
A 50 s quasi-periodic oscillation in the early X-ray afterglow of GRB 220711B
H. Gao, W. -H. Lei, S. Xiao +19
It is generally believed that long duration gamma-ray bursts (GRBs) originate from the core collapse of rapidly spinning massive stars and at least some of them are powered by hype…
