The Karl G. Jansky Very Large Array Local Group L-band Survey (LGLBS)

Eric W. Koch, Adam K. Leroy, Erik W. Rosolowsky +45

We present the Local Group L-Band Survey (LGLBS), a Karl G. Jansky Very Large Array (VLA) survey producing the highest quality 21-cm and 1-2 GHz radio continuum images to date for…

Relationships between PAHs, Small Dust Grains, H, and HI in Local Group Dwarf Galaxies NGC 6822 and WLM Using JWST, ALMA, and the VLA

Ryan Chown, Adam K. Leroy, Alberto D. Bolatto +27

We present 0.7-3.3 pc resolution mid-infrared (MIR) JWST images at 7.7 m (F770W) and 21 m (F2100W) covering the main star-forming regions of two of the closest star-forming l…

Compact and High Excitation Molecular Clumps in the Extended Ultraviolet Disk of M83

Jin Koda, Francoise Combes, Monica Rubio +9

The extended ultraviolet (XUV) disks of nearby galaxies show ongoing massive star formation, but their parental molecular clouds remain mostly undetected despite searches in CO(1-0…

A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk

Olivier Berné, Emilie Habart, Els Peeters +143

Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…

ALMA-LEGUS II: The Influence of Sub-Galactic Environment on Molecular Cloud Properties

Molly K. Finn, Kelsey E. Johnson, Remy Indebetouw +24

We compare the molecular cloud properties in sub-galactic regions of two galaxies, barred spiral NGC 1313, which is forming many massive clusters, and flocculent spiral NGC 7793, w…

ALMA-LEGUS I: The Influence of Galaxy Morphology on Molecular Cloud Properties

Molly K. Finn, Kelsey E. Johnson, Remy Indebetouw +24

We present a comparative study of the molecular gas in two galaxies from the LEGUS sample: barred spiral NGC 1313 and flocculent spiral NGC 7793. These two galaxies have similar ma…

GBT/Argus Observations of Molecular Gas in the Inner Regions of IC 342

Jialu Li, Andrew I Harris, Erik Rosolowsky +9

We report observations of the ground state transitions of CO, CO CO, HCN, and HCO at 88-115 GHz in the inner region of the nearby galaxy IC 342. These data…

PDRs4All III: JWST's NIR spectroscopic view of the Orion Bar

Els Peeters, Emilie Habart, Olivier Berne +135

(Abridged) We investigate the impact of radiative feedback from massive stars on their natal cloud and focus on the transition from the HII region to the atomic PDR (crossing the i…

Where do stars explode in the ISM? -- The distribution of dense gas around evolved massive stars in M33

Sumit K. Sarbadhicary, Jordan Wagner, Eric W. Koch +27

The effect of supernovae (SNe) on star-formation in the interstellar medium (ISM) depends sensitively on where SNe explode with respect to ISM clouds. Observationally, SN ISM envir…

PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula

Emilie Habart, Els Peeters, Olivier Berné +139

The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…

Diverse Molecular Structures Across The Whole Star-Forming Disk of M83: High fidelity Imaging at 40pc Resolution

Jin Koda, Akihiko Hirota, Fumi Egusa +23

We present high-fidelity CO(1-0) imaging of molecular gas across the full star-forming disk of M83, using ALMA's 12m, 7m, and TP arrays and the MIRIAD package. The data have a mass…

A far-IR view of the starburst driven superwind in NGC 2146

K. Kreckel, L. Armus, B. Groves +19

NGC 2146, a nearby luminous infrared galaxy (LIRG), presents evidence for outflows along the disk minor axis in all gas phases (ionized, neutral atomic and molecular). We present a…

The CO-to-H2 Conversion Factor and Dust-to-Gas Ratio on Kiloparsec Scales in Nearby Galaxies

K. M. Sandstrom, A. K. Leroy, F. Walter +42

We present kiloparsec (kpc) spatial resolution maps of the CO-to-H2 conversion factor (alpha_co) and dust-to-gas ratio (DGR) in 26 nearby, star-forming galaxies. We have simultaneo…
