Extremely metal-poor gas at a redshift of 7
Robert A. Simcoe, Peter W. Sullivan, Kathy L. Cooksey +3
In typical astrophysical environments, the abundance of heavy elements ranges from 0.001 to 2 times the solar concentration. Lower abundances have been seen in select stars in the…
A Massive, Cooling-Flow-Induced Starburst in the Core of a Highly Luminous Galaxy Cluster
M. McDonald, M. Bayliss, B. A. Benson +83
In the cores of some galaxy clusters the hot intracluster plasma is dense enough that it should cool radiatively in the cluster's lifetime, leading to continuous "cooling flows" of…
A Calibrated Measurement of the Near-IR Continuum Sky Brightness Using Magellan/FIRE
Peter W. Sullivan, Robert A. Simcoe
We characterize the near-IR sky background from 308 observations with the FIRE spectrograph at Magellan. A subset of 105 observations selected to minimize lunar and thermal effects…
