Probing the Properties of Neutral Clouds in the Vicinity of the Local Bubble: Linking three-dimensional Dust with Neutral Hydrogen Absorption

Aishani Das-Ghosh, Nickolas Pingel, Snežana Stanimirović

The Local Bubble (LB) contains significant internal structure, with many interstellar clouds lying within or on its walls. By observing time variability of atomic neutral hydrogen (HI) absorption profiles in the direction of pulsars, it was suggested that some of the HI …

A Multiwavelength Inventory for the Local Group L-band Survey I: Atlas and Radial Profiles of Local Group Galaxies

Cosima Eibensteiner, Adam K. Leroy, Jiayi Sun, Erik Roslowsky et autres

Resolving atomic gas at $\lesssim100$ pc physical resolution is currently feasible only for the very nearest galaxies. We combine 120 pc resolution HI data using the Karl G. Jansky Very Large Array (VLA) from the first data release of the Local Group …

Revisiting Ram Pressure Stripping in Wolf–Lundmark–Melotte: No Evidence for Stripped H I with Local Group L -Band Survey

Daniel R. Rybarczyk, Eric W. Koch, Fabian Caballero Vargas, Snežana Stanimirović et autres

Abstract We analyze H i 21 cm observations of the Local Group dwarf galaxy Wolf–Lundmark–Melotte (WLM) from the Local Group L -Band Survey to search for evidence of ram pressure stripping. While previous MeerKAT-16 observations of WLM showed evidence for off-galaxy atomic …

Revisiting ram pressure stripping in Wolf-Lundmark-Melotte: No evidence for stripped HI with LGLBS

Daniel R. Rybarczyk, Eric W. Koch, Fabian Caballero Vargas, Snežana Stanimirović et autres

We analyze HI 21-cm observations of the Local Group dwarf galaxy Wolf-Lundmark-Melotte (WLM) from the Local Group L-Band Survey to search for evidence of ram pressure stripping. While previous MeerKAT-16 observations of WLM showed evidence for off-galaxy atomic gas emission with a …

Revealing the cold skeleton of the Magellanic clouds and the Magellanic Bridge with ASKAP

James Dempsey, N M McClure-Griffiths, Antoine Marchal, S E Clark et autres

ABSTRACT We present the GASKAP-HI pilot absorption survey of neutral hydrogen (H i) in the Magellanic system. This survey provides 3219 sightlines across the Large (LMC) and Small Magellanic Clouds (SMC) and the Magellanic Bridge (MB) towards 1.4-GHz continuum sources, representing a …

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, Ness Mayker Chen et autres

Abstract 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 environments characterized by spatially resolved gas maps can empirically guide the placement of SNe …

The Local Group L -band Survey: Probing Cold Atomic Gas in IC 10 with Neutral Hydrogen Absorption

Ioana A. Stelea, Snežana Stanimirović, Nickolas M. Pingel, Hongxing Chen et autres

Abstract We present the first localized detections of the cold neutral medium (CNM) in IC 10, offering a rare view of dense atomic gas in a low-metallicity ( Z / Z ⊙ ∼ 0.27) dwarf galaxy. As a low-metallicity starburst, IC 10’s …

A High-resolution Study of the Cold Neutral Medium in and around 30 Doradus

Gyueun Park, Min-Young Lee, J. M. Dickey, N. M. Pingel et autres

Abstract With the aim of evaluating the roles of the cold neutral medium (CNM) in the cloud-scale baryon cycle, we perform a high-resolution study of the CNM in and around the extreme star-forming region 30 Doradus (30 Dor). For our study, we …
