Detection of metal absorption lines in quasar spectra: a neural network approach using U-Net
Elena Sofia Mangola, Francesco Pistis, Michele Fumagalli +7
Current and future large spectroscopic surveys are significantly enhancing the volume and resolution of quasar spectra that are observed, which requires the creation of efficient a…
Detection of an Extended Ly Halo around a Broad Absorption Line Quasar with the Keck Cosmic Web Imager
Raymond P. Remigio, Aaron J. Barth, Feige Wang +6
We present the first results from a program searching for extended Ly halos around high redshift () quasars using the red channel of the Keck Cosmic Web Imager (…
Unmixed metals: Variations in the enrichment of z~4 sub-damped Lyman alpha systems
Trystyn A. M. Berg, Louise A. Welsh, Ryan J. Cooke +4
The chemical abundance patterns of near-pristine objects provide important constraints on the properties of the first generations of stars in the Universe. We present the chemical…
KBSS-InCLOSE I: Design and First Results from the Inner CGM of QSO Line Of Sight Emitting Galaxies at z~2-3
Evan Haze Nunez, Charles C. Steidel, Evan N. Kirby +10
We present the design and first results of the Inner Circumgalactic Medium (CGM) of QSO Line of Sight Emitting galaxies at , KBSS-InCLOSE. The survey will connect galaxy…
MUSE Analysis of Gas around Galaxies (MAGG) -- II: Metal-enriched halo gas around z~1 galaxies
Rajeshwari Dutta, Michele Fumagalli, Matteo Fossati +8
We present a study of the metal-enriched cool halo gas traced by MgII absorption around 228 galaxies at z~0.8-1.5 within 28 quasar fields from the MUSE Analysis of Gas around Galax…
The MUSE Ultra Deep Field (MUDF). I. Discovery of a group of Ly nebulae associated with a bright quasar pair
E. Lusso, M. Fumagalli, M. Fossati +17
We present first results from Multi Unit Spectroscopic Explorer (MUSE) observations at the Very Large Telescope in the MUSE Ultra Deep Field (MUDF), a arcmi…
The Little Cub: Discovery of an Extremely Metal-Poor Star-Forming Galaxy in the Local Universe
Tiffany Hsyu, Ryan J. Cooke, J. Xavier Prochaska +1
We report the discovery of the Little Cub, an extremely metal-poor star-forming galaxy in the local Universe, found in the constellation Ursa Major (a.k.a. the Great Bear). We firs…
