Deep Learning Voigt Profiles I. Single-Cloud Doublets
Bryson Stemock, Christopher W. Churchill, Avery Lee +3
Voigt profile (VP) decomposition of quasar absorption lines is key to studying intergalactic gas and the baryon cycle governing the formation and evolution of galaxies. The VP velo…
The environments and hosts of metal absorption at z>5
Caitlin C. Doughty, Kristian M. Finlator
A growing population of metal absorbers are observed at z>5, many showing strong evolution in incidence approaching the epoch of hydrogen reionization. Follow-up surveys examining…
Using cosmological simulations and synthetic absorption spectra to assess the accuracy of observationally derived CGM metallicities
Rachel Marra, Christopher W. Churchill, Caitlin Doughty +6
We used adaptive mesh refinement hydrodynamic cosmological simulations of a Milky Way-type galaxy and a Dwarf galaxy and generated synthetic quasar absorption-line spec…
The effects of binary stars on galaxies and metal-enriched gas during reionization
Caitlin C. Doughty, Kristian M. Finlator
Binary stars are abundant in nearby galaxies, but are typically unaccounted for in simulations of the high redshift Universe. Stellar population synthesis models that include the e…
Evolution of CIV Absorbers I. The Cosmic Incidence
Farhanul Hasan, Christopher W. Churchill, Bryson Stemock +7
We present a large high-resolution study of the distribution and evolution of CIV absorbers, including the weakest population with equivalent widths ~Å. By searching 369 h…
The Faint Host Galaxies of C IV Absorbers at z > 5
Kristian Finlator, Caitlin Doughty, Zheng Cai +1
We explore the expected galaxy environments of CIV absorbers at z>5 using the Technicolor Dawn simulations. These simulations reproduce the observed history of reionization, the z~…
