All the Little Things in Abell 2744: 1000 Gravitationally Lensed Dwarf Galaxies at from JWST NIRCam Grism Spectroscopy
Rohan P. Naidu, Jorryt Matthee, Ivan Kramarenko +31
Dwarf galaxies hold the key to crucial frontiers of astrophysics, however, their faintness renders spectroscopy challenging. Here we present the JWST Cycle 2 survey, All the Little…
Rising from the ashes: evidence of old stellar populations and rejuvenation events in the very early Universe
Callum Witten, William McClymont, Nicolas Laporte +12
While JWST has observed galaxies assembling as early as , evidence of galaxies with significant old stellar populations in the Epoch of Reionisation (EoR) -- the descendan…
The impact of nebular Lyman-Continuum on ionising photons budget and escape fractions from galaxies
C. Simmonds, A. Verhamme, A. K. Inoue +3
Several Lyman Continuum (LyC) emitters have been detected so far, but their observed ionising spectra sometimes differ from attenuated stellar spectra predicted by stellar populati…
The Highest-Redshift Balmer Breaks as a Test of CDM
Charles L. Steinhardt, Albert Sneppen, Thorbjørn Clausen +3
Recent studies have reported tension between the presence of luminous, high-redshift galaxies and the halo mass functions predicted by standard cosmology. Here, an improved test is…
Simulating the diversity of shapes of the Lyman- line
Jeremy Blaizot, Thibault Garel, Anne Verhamme +6
The Ly line is a powerful probe of distant galaxies, which contains information about inflowing/outflowing gas through which Ly photons scatter. To develop our understanding…
Nitrogen enhancements 440 Myr after the Big Bang: super-solar N/O, a tidal disruption event or a dense stellar cluster in GN-z11?
Alex J. Cameron, Harley Katz, Martin P. Rey +1
Recent observations of GN-z11 with JWST/NIRSpec revealed numerous oxygen, carbon, nitrogen, and helium emission lines at . Using the measured line fluxes, we derive abundan…
