JWST Reveals Bulge-dominated Star-forming Galaxies at Cosmic Noon
Chloë E. Benton, Erica J. Nelson, Tim B. Miller +10
Hubble Space Telescope imaging shows that most star-forming galaxies at cosmic noon -- the peak of cosmic star formation history -- appear disk-dominated, leaving the origin of the…
Unravelling the role of merger histories in the population of In situ stars: linking IllustrisTNG cosmological simulation to H3 survey
Razieh Emami, Lars Hernquist, Randall Smith +16
We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with…
AGN Feedback in Quiescent Galaxies at Cosmic Noon Traced by Ionized Gas Emission
Letizia Bugiani, Sirio Belli, Minjung Park +17
We analyze ionized gas emission lines in deep rest-frame optical spectra of 16 quiescent galaxies at redshift observed with JWST/NIRSpec by the Blue Jay survey. Robust…
Widespread rapid quenching at cosmic noon revealed by JWST deep spectroscopy
Minjung Park, Sirio Belli, Charlie Conroy +16
Massive quiescent galaxies in the young universe are expected to be quenched rapidly, but it is unclear whether they all experience starbursts before quenching and what physical me…
JWST Reveals Widespread AGN-Driven Neutral Gas Outflows in Massive z ~ 2 Galaxies
Rebecca L. Davies, Sirio Belli, Minjung Park +15
We use deep JWST/NIRSpec R~1000 slit spectra of 113 galaxies at 1.7 < z < 3.5, selected from the mass-complete Blue Jay survey, to investigate the prevalence and typical properties…
Star Formation Shut Down by Multiphase Gas Outflow in a Galaxy at a Redshift of 2.45
Sirio Belli, Minjung Park, Rebecca L. Davies +15
Large-scale outflows driven by supermassive black holes are thought to play a fundamental role in suppressing star formation in massive galaxies. However, direct observational evid…
