Molecular Gas Properties and CO-to-H2 Conversion Factors in the Central Kiloparsec of NGC 3351
Yu-Hsuan Teng, Karin M. Sandstrom, Jiayi Sun +16
The CO-to-H conversion factor ($α_\rm{CO}$) is critical to studying molecular gas and star formation in galaxies. The value of $α_\rm{CO}$ has been found to vary within and bet…
CO(2-1)/CO(1-0) line ratio on 100 parsec scale in the nearby barred galaxy NGC1300
Fumiya Maeda, Fumi Egusa, Kouji Ohta +3
CO(2-1) emission is often used as a tracer of the giant molecular clouds (GMCs) as an alternative to CO(1-0) emission in recent years. Therefore, understanding the environmental de…
APOGEE Detection of N-rich stars in the tidal tails of Palomar 5
Sian G. Phillips, Ricardo P. Schiavon, J. Ted Mackereth +15
Recent results from chemical tagging studies using APOGEE data suggest a strong link between the chemical abundance patterns of stars found within globular clusters, and chemically…
Reconciling the Results of the z~2 MOSDEF and KBSS-MOSFIRE Surveys
Jordan N. Runco, Naveen A. Reddy, Alice E. Shapley +21
The combination of the MOSDEF and KBSS-MOSFIRE surveys represents the largest joint investment of Keck/MOSFIRE time to date, with ~3000 galaxies at 1.4<=z<=3.8, roughly half of whi…
Characterizing Protoclusters and Protogroups at z 2.5 Using Ly Tomography
Mahdi Qezlou, Andrew B. Newman, Gwen C. Rudie +1
Ly- tomography surveys have begun to produce three-dimensional (3D) maps of the intergalactic medium (IGM) opacity at with Mpc resolution. These surveys provide an…
Simultaneous Constraints on the Star Formation History and Nucleosynthesis of Sculptor dSph
Mithi A. C. de los Reyes, Evan N. Kirby, Alexander P. Ji +1
We demonstrate that using up to seven stellar abundance ratios can place observational constraints on the star formation histories (SFHs) of Local Group dSphs, using the Sculptor d…
Direct Constraints on the Extremely Metal-Poor Massive Stars Underlying Nebular C IV Emission from Ultra-Deep HST/COS Ultraviolet Spectroscopy
Peter Senchyna, Daniel P. Stark, Stephane Charlot +8
Metal-poor nearby galaxies hosting massive stars have a fundamental role to play in our understanding of both high-redshift galaxies and low metallicity stellar populations. But wh…
PHANGS-MUSE: the HII region luminosity function of local star-forming galaxies
Francesco Santoro, Kathryn Kreckel, Francesco Belfiore +30
We use an unprecedented sample of about 23,000 HII regions detected at an average physical resolution of 67pc in the PHANGS-MUSE sample to study the extragalactic HII region Ha lum…
A tale of two DIGs: The relative role of HII regions and low-mass hot evolved stars in powering the diffuse ionised gas (DIG) in PHANGS-MUSE galaxies
Francesco Belfiore, Francesco Santoro, Brent Groves +17
We use integral field spectroscopy from the PHANGS-MUSE survey, which resolves the ionised interstellar medium at pc resolution in 19 nearby spiral galaxies, to study th…
Gravitational Microlensing Rates in Milky Way Globular Clusters
Fulya Kıroğlu, Newlin C. Weatherford, Kyle Kremer +3
Many recent observational and theoretical studies suggest that globular clusters (GCs) host compact object populations large enough to play dominant roles in their overall dynamica…
Wide binaries from the H3 survey: the thick disk and halo have similar wide binary fractions
Hsiang-Chih Hwang, Yuan-Sen Ting, Charlie Conroy +8
Due to the different environments in the Milky Way's disk and halo, comparing wide binaries in the disk and halo is key to understanding wide binary formation and evolution. By usi…
Tracing the Ionization Structure of the Shocked Filaments of NGC 6240
Anne M. Medling, Lisa J. Kewley, Daniela Calzetti +14
We study the ionization and excitation structure of the interstellar medium in the late-stage gas-rich galaxy merger NGC 6240 using a suite of emission line maps at 25 pc res…
Evidence from Disrupted Halo Dwarfs that -process Enrichment via Neutron Star Mergers is Delayed by Myrs
Rohan P. Naidu, Alexander P. Ji, Charlie Conroy +10
The astrophysical origins of -process elements remain elusive. Neutron star mergers (NSMs) and special classes of core-collapse supernovae (rCCSNe) are leading candidates. Due t…
The Cosmic Ultraviolet Baryon Survey (CUBS) IV: The Complex Multiphase Circumgalactic Medium as Revealed by Partial Lyman Limit Systems
Thomas J. Cooper, Gwen C. Rudie, Hsiao-Wen Chen +18
We present a detailed study of two partial Lyman limit systems (pLLSs) of neutral hydrogen column density discovered at…
HI mapping of the Leo Triplet: Morphologies and kinematics of tails and bridges
Gang Wu, David Martínez-Delgado, Christian Henkel +9
A fully-sampled and hitherto highest resolution and sensitivity observation of neutral hydrogen (HI) in the Leo Triplet (NGC 3628, M 65/NGC 3623, and M 66/NGC 3627) reveals six HI…
Comparing the pre-SNe feedback and environmental pressures for 6000 HII regions across 19 nearby spiral galaxies
A. T. Barnes, S. C. O. Glover, K. Kreckel +28
The feedback from young stars (i.e. pre-supernova) is thought to play a crucial role in molecular cloud destruction. In this paper, we assess the feedback mechanisms acting within…
