The ALMaQUEST Survey XVII: Unveiling Multiple Quenching Pathways in Green Valley Galaxies via Molecular Gas and Quenching Timescale Analyses
Lihwai Lin, Po-Feng Wu, Mallory D. Thorp +6
Statistically, green valley (GV) galaxies exhibit lower molecular gas fractions () and reduced star formation efficiency (SFE) compared to star-forming galaxies. However,…
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…
The CIViL* Survey: The Discovery of a C IV Dichotomy in the CGM of L* Galaxies
Samantha L. Garza, Jessica K. Werk, Trystyn A. M. Berg +4
This paper investigates C IV absorption in the circumgalactic medium (CGM) of L* galaxies and its relationship with galaxy star formation rates. We present new observations from th…
Stellar Populations With Optical Spectra: Deep Learning vs. Popular Spectrum Fitting Codes
Joanna Woo, Dan Walters, Finn Archinuk +4
We compare the performance of several popular spectrum fitting codes (Firefly, starlight, pyPipe3D and pPXF), and a deep-learning convolutional neural network (StarNet), in recover…
-M* Diagram: A Valuable Galaxy Evolution Diagnostic to Complement (s)SFR-M* Diagrams
Samir Salim, Sandro Tacchella, Chandler Osborne +3
The specific star formation rate (sSFR) is commonly used to describe the level of galaxy star formation (SF) and to select quenched galaxies. However, being a relative measure of t…
Hunting for Metals Using XQ-100 Legacy Survey Composite Spectra
S. Perrotta, V. D'Odorico, F. Hamann +10
We investigate the NV absorption signal along the line of sight of background quasars, in order to test the robustness of the use of this ion as criterion to select intrinsic (i.e.…
On the selection of damped Lyman alpha systems using MgII absorption at 2<z<4
T. A. M. Berg, S. L. Ellison, J. X. Prochaska +8
The XQ-100 survey provides optical and near infrared coverage of 36 blindly selected, intervening damped Lyman alpha systems (DLAs) at 2 < z < 4, simultaneously covering the MgII d…
The chemistry of the most metal-rich damped Lyman systems at z II. Context with the Local Group
Trystyn A. M. Berg, Sara L. Ellison, J. Xavier Prochaska +2
Using our sample of the most metal-rich damped Lyman systems (DLAs) at z, and two literature compilations of chemical abundances in 341 DLAs and 2818 stars, we present a…
