Ultraviolet Properties of Multi-phase Gas Toward the Inner Galaxy
Frances H. Cashman, Andrew J. Fox, Debopam Som +6
We present a systematic study of the multi-phase interstellar gas in the Inner Galaxy using HST/STIS absorption spectroscopy of 16 massive stars located at spectroscopic distances…
Metals and a Search for Molecules in the Distant Universe: Magellan MIKE Observations of sub-DLAs at 2<z<3
Suraj Poudel, Varsha P. Kulkarni, Debopam Som +1
We present abundance measurements of the elements Zn, S, O, C, Si and Fe for four sub-DLAs at redshifts ranging from z=2.173 to z=2.635 using observations from the MIKE spectrograp…
Probing Structure in Cold Gas at with Gravitationally Lensed Quasar Sight Lines
Varsha P. Kulkarni, Frances H. Cashman, Sebastian Lopez +3
Absorption spectroscopy of gravitationally lensed quasars (GLQs) enables study of spatial variations in the interstellar and/or circumgalactic medium of foreground galaxies. We rep…
Spectroscopic QUasar Extractor and redshift (z) EstimatorSQUEzE I: Methodology
Ignasi Pérez-Ràfols, Matthew M. Pieri, Michael Blomqvist +2
We present SQUEzE, a software package to classify quasar spectra and estimate their redshifts. SQUEzE is a random forest classifier operating on the parameters of candidate emissio…
A High Signal-to-Noise HST Spectrum Toward J1009+0713: Precise Absorption Measurements in the CGM of Two Galaxies
Cassandra Lochhaas, Smita Mathur, Stephan Frank +6
High signal-to-noise spectra toward background quasars are crucial for uncovering weak absorption in the circumgalactic medium (CGM) of intervening galaxies, such as the diagnostic…
Early metal enrichment of gas-rich galaxies at z~5
Suraj Poudel, Varsha P. Kulkarni, Sean Morrison +4
We present abundance measurements of elements O, C, Si and Fe for three gas-rich galaxies at z~5 using observations from the Very Large Telescope (VLT) and the Keck telescope in or…
