Circumgalactic CIV Absorption Found Only Within 30 Degrees of the Minor Axis of Present-Epoch Galaxies
Mark A. Croom, Christopher W. Churchill, Bart Wakker +2
We studied CIV 1548,1550 absorption in the circumgalactic medium (CGM) of 88 isolated, bright (L_B > 0.2L*_B) galaxies at z < 0.03 selected without prior knowledge of CGM absorptio…
SN 2024gy: Multi-epoch Spectroscopic Features Suggestive of Delayed Detonation in a Type Ia Supernova
Liping Li, Zhenyu Wang, Jialian Liu +28
We present photometric and spectroscopic observations of SN 2024gy, a Type Ia supernova (SN Ia) exhibiting high-velocity features (HVFs) in its early-time spectra. This SN reaches…
Evolution of CIV Absorbers. II. Where does CIV live?
Farhanul Hasan, Christopher W Churchill, Bryson Stemock +4
We use the observed cumulative statistics of CIV absorbers and dark matter halos to infer the distribution of CIV-absorbing gas relative to galaxies at redshifts $0\!\leq\!z\!\leq\…
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…
