Disentangling CO Chemistry in a Protoplanetary Disk Using Explanatory Machine Learning Techniques
Amina Diop, Ilse Cleeves, Dana Anderson +2
Molecular abundances in protoplanetary disks are highly sensitive to the local physical conditions, including gas temperature, gas density, radiation field, and dust properties. Of…
The physical properties of T Pyx as measured by MUSE I. The geometrical distribution of the ejecta and the distance to the remnant
L. Izzo, L. Pasquini, E. Aydi +8
T Pyx is one of the most enigmatic recurrent novae, and it has been proposed as a potential Galactic type-Ia supernova progenitor. Using spatially-resolved data obtained with MUSE,…
Deciphering the JWST spectrum of a 'little red dot' at : An obscured AGN and its star-forming host
Meghana Killi, Darach Watson, Gabriel Brammer +10
JWST has revealed a class of numerous, extremely compact sources, with rest-frame red optical/near-infrared (NIR) and blue ultraviolet (UV) colours, nicknamed "little red dots". We…
Classifying Intermediate Redshift Galaxies in SDSS: Alternative Diagnostic Diagrams
Léa Feuillet, Marcio Meléndez, Steve Kraemer +3
We select a sample of 1,437 active galactic nuclei (AGN) from the catalog of the Sloan Digital Sky Survey (SDSS) galaxy properties from the Portsmouth group by detection of the hig…
JWST's PEARLS: 119 multiply imaged galaxies behind MACS0416, lensing properties of caustic crossing galaxies, and the relation between halo mass and number of globular clusters at
Jose M. Diego, Nathan J. Adams, Steven Willner +26
We present a new lens model for the galaxy cluster MACS J0416.12403 based on a previously known set of 77 spectroscopically confirmed, multiply imaged galaxies plus an…
The PHANGS-AstroSat Atlas of Nearby Star Forming Galaxies
Hamid Hassani, Erik Rosolowsky, Eric W. Koch +29
We present the Physics at High Angular resolution in Nearby GalaxieS (PHANGS)-AstroSat atlas, which contains ultraviolet imaging of 31 nearby star-forming galaxies captured by the…
