Detecting HI Self-Absorption using Neural Networks
Eric G. M. Muller, Naomi M. McClure-Griffiths, Hiep Nguyen +5
Cold atomic hydrogen plays a crucial role in the life cycle of interstellar gas. It serves as the intermediary phase in the condensation and cooling processes that bridge the warm…
A Detailed GASKAP-HI View of Shells and Loops in the Magellanic Bridge
Shin-Jeong Kim, Antoine Marchal, N. M. McClure-Griffiths +19
We present 8 pc-scale GASKAP-HI observations of an HI shell (diameter \sim130 pc) associated with the Hαshell DEM171 in the Magellanic Bridge. The Bridge's diffuse, HI-dominated en…
The MAGPI Survey: Emission Line Products Data Release and the Role of Spectroscopic Aperture Covering Fraction on the Balmer Decrement-Stellar Mass Relation
A. J. Battisti, E. G. M. Muller, E. Wisnioski +27
The Middle Ages Galaxy Properties with Integral field spectroscopy (MAGPI) survey is a Large Program on the European Southern Observatory Very Large Telescope using the MUSE instru…
A High-resolution Study of the Cold Neutral Medium in and around 30 Doradus
Gyueun Park, Min-Young Lee, John M. Dickey +17
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-…
Multi-wavelength probes of the Milky Way's Cold Interstellar Medium: Radio HI and Optical KI Absorption with GASKAP and GALAH
Hiep Nguyen, Sven Buder, Juan D. Soler +19
We present a comparative analysis of interstellar hydrogen (HI) and potassium (KI) absorption from the radio and optical surveys, GASKAP and GALAH, to study the physical and kinema…
The MAGPI Survey: the kinematic morphology-density relation (or lack thereof) and the Hubble sequence at
Caroline Foster, Mark W. Donoghoe, Andrew Battisti +26
This work presents visual morphological and dynamical classifications for 637 spatially resolved galaxies, most of which are at intermediate redshift (), in the Middle-Ag…
The MAGPI Survey: radial trends in star formation across different cosmological simulations in comparison with observations at 0.3
Marcie Mun, Emily Wisnioski, Katherine E. Harborne +20
We investigate the internal and external mechanisms that regulate and quench star formation (SF) in galaxies at using MAGPI observations and the EAGLE, Magneticum, and…
TPCNet: Representation learning for HI mapping
Hiep Nguyen, Haiyang Tang, Matthew Alger +4
We introduce TPCNet, a neural network predictor that combines Convolutional and Transformer architectures with Positional encodings, for neutral atomic hydrogen (HI) spectral analy…
The MAGPI Survey: Orbital distributions, intrinsic shapes, and mass profiles for MAGPI-like Eagle galaxies using Schwarzschild dynamical models
Giulia Santucci, Claudia Del P. Lagos, Katherine E. Harborne +16
Schwarzschild dynamical models are now regularly employed in large surveys of galaxies in the local and distant Universe to derive information on galaxies' intrinsic properties suc…
