An emerging baryon cycle in a galaxy 500 million years after the Big Bang
Shengzhe Wang, Xin Wang, Hang Zhou +17
The emergence of stellar feedback as a regulator of galaxy growth marks a fundamental transition in cosmic history. At early times, rapid gas accretion and collapse may induce inte…
Consistent Gas-Phase Temperatures and Metallicities from UV and Optical Nebular Emission: A Reliable Foundation from z=0 to Cosmic Dawn
Erin Huntzinger, Yuguang Chen, Tucker Jones +6
The rest-frame UV spectra of star-forming galaxies are increasingly important as they become one of the primary windows to probe the physical properties of cosmic dawn (z>8) galaxi…
Surprising increase of electron temperature in metal-rich star-forming region
Ziming Peng, Renbin Yan, Zesen Lin +3
The electron temperature is a crucial parameter for the determination of the gas-phase metallicity of galaxies. Low electron temperature is expected for metal-rich galaxies, theore…
Consistent gas-phase C/O abundances from UV and optical emission lines: a robust scale for chemical evolution across cosmic time
Paige M. Kelly, Tucker Jones, Yuguang Chen +5
The carbon to oxygen (C/O) abundance ratio is a valuable tracer of star formation history, as C and O enrichment occurs on different timescales. However, measurements based on ultr…
Mapping the z ~ 2 Circumgalactic Medium using KBSS Galaxy Pairs
Nikolaus Z. Prusinski, Charles C. Steidel, Yuguang Chen
We present new results on the spatial structure and kinematics of the circumgalactic medium (CGM) of z ~ 2 star-forming galaxies drawn from the Keck Baryonic Structure Survey, usin…
Resolved Stellar and Nebular Kinematics of a Star-forming Galaxy at
Sunny Rhoades, Tucker Jones, Keerthi Vasan G. C. +7
The kinematics of star-forming galaxy populations at high redshifts are integral to our understanding of disk properties, merger rates, and other defining characteristics. Nebular…
