The Diversity of Metal-Enrichment and Abundance Patterns at High Redshift: A Magellan Survey of Gas-rich Galaxies Traced by Damped Lyman-alpha Absorbers at z~5
Jianghao Huyan, Varsha P. Kulkarni, Suraj Poudel +3
A powerful technique to trace the signatures of the first stars is through the metal enrichment in concentrated reservoirs of hydrogen, such as the damped Lyman-alpha absorbers (DL…
The Baryonic Content of Galaxies Mapped by MaNGA and the Gas Around Them
Viacheslav V. Klimenko, Varsha Kulkarni, David A. Wake +4
We analyze the cool gas in and around 14 nearby galaxies (at 0.1) mapped with the SDSS-IV MaNGA survey by measuring absorption lines produced by gas in spectra of background…
Revealing the Nature of a Lyman- Halo in a Strongly Lensed Interacting System at
Manuel Solimano, Jorge González-López, Manuel Aravena +12
Spatially extended halos of H I Ly emission are now ubiquitously found around high-redshift star-forming galaxies. But our understanding of the nature and powering mechanisms of…
Telltale signs of metal recycling in the circumgalactic medium of a galaxy
N. Tejos, S. López, C. Ledoux +15
We present gravitational-arc tomography of the cool-warm enriched circumgalactic medium (CGM) of an isolated galaxy (``G1'') at . Combining VLT/MUSE adaptive-optics…
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…
Metal-enriched Galaxies in the First ~1 Billion Years: Evidence of a Smooth Metallicity Evolution at z ~ 5
Suraj Poudel, Varsha P. Kulkarni, Frances H. Cashman +4
We present seven new abundance measurements of the elements O, C and Si at z > 4.5, doubling the existing sample of weakly depleted elements in gas-rich galaxies, in order to const…
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…
