RESOLVE and ECO: Finding Low-Metallicity Dwarf AGN Candidates Using Optimized Emission-Line Diagnostics
Mugdha S. Polimera, Sheila J. Kannappan, Chris T. Richardson +6
Existing star-forming vs. active galactic nucleus (AGN) classification schemes using optical emission-line diagnostics mostly fail for low-metallicity and/or highly star-forming ga…
Galaxy Morphological Classification Catalogue of the Dark Energy Survey Year 3 data with Convolutional Neural Networks
Ting-Yun Cheng, Christopher J. Conselice, Alfonso Aragón-Salamanca +57
We present in this paper one of the largest galaxy morphological classification catalogues to date, including over 20 million of galaxies, using the Dark Energy Survey (DES) Year 3…
A machine learning approach to galaxy properties: joint redshift-stellar mass probability distributions with Random Forest
S. Mucesh, W. G. Hartley, A. Palmese +72
We demonstrate that highly accurate joint redshift-stellar mass probability distribution functions (PDFs) can be obtained using the Random Forest (RF) machine learning (ML) algorit…
Void Galaxies Follow a Distinct Evolutionary Path in the Environmental COntext Catalog
Jonathan Florez, Andreas A. Berlind, Sheila J. Kannappan +6
We measure the environmental dependence, where environment is defined by the distance to the third nearest neighbor, of multiple galaxy properties inside the Environmental COntext…
Linking Compact Dwarf Starburst Galaxies in the RESOLVE Survey to Downsized Blue Nuggets
Michael L. Palumbo, Sheila J. Kannappan, Elaine M. Frazer +12
We identify and characterize compact dwarf starburst (CDS) galaxies in the RESOLVE survey, a volume-limited census of galaxies in the local universe, to probe whether this populati…
Supernova Siblings: Assessing the Consistency of Properties of Type Ia Supernovae that Share the Same Parent Galaxies
D. Scolnic, M. Smith, A. Massiah +82
While many studies have shown a correlation between properties of the light curves of Type Ia SN (SNe Ia) and properties of their host galaxies, it remains unclear what is driving…
