Connecting JWST discovered N/O-enhanced galaxies to globular clusters: Evidence from chemical imprints
Xihan Ji, Vasily Belokurov, Roberto Maiolino +5
Recent JWST observations have revealed a growing population of galaxies at with elevated nitrogen-to-oxygen ratios. These "N/O-enhanced" galaxies (NOEGs) exhibit near- to sup…
Effect of ionizing photon escape fraction in faint galaxies on modeling reionization history of the universe
Zewei Wu, Andrey Kravtsov, Harley Katz
We present model calculations of the reionization history of hydrogen using star formation histories, computed with a galaxy formation model which reproduces properties of local dw…
Bursting at the seams: the star-forming main sequence and its scatter at z=3-9 using NIRCam photometry from JADES
C. Simmonds, S. Tacchella, W. McClymont +24
We present a comprehensive study of the star-forming main sequence (SFMS) and its scatter at redshifts , using NIRCam photometry from the JADES survey in the GOODS…
Blind source separation of the stellar halo
Elliot Y. Davies, Vasily Belokurov, Andrey Kravtsov +4
The stellar halo of the Milky Way comprises an abundance of chemical signatures from accretion events and \textit{in-situ} evolution, that form an interweaving tapestry in kinemati…
On the connection between nitrogen-enhanced field stars and the Galactic globular clusters
Sarah G. Kane, Vasily Belokurov, Stephanie Monty +6
As sites of some of the most efficient star formation in the Universe, globular clusters (GCs) have long been hypothesized to be the building blocks of young galaxies. Within the M…
Updated bounds on ultra-light dark matter from the tiniest galaxies
Simon May, Neal Dalal, Andrey Kravtsov
The particle mass of dark matter (DM) was previously constrained using kinematics of ultra-faint dwarf galaxies to . This constraint, which excl…
