Insights on Galaxy Evolution from Interpretable Sparse Feature Networks
John F. Wu
Galaxy appearances reveal the physics of how they formed and evolved. Machine learning models can now exploit galaxies' information-rich morphologies to predict physical properties…
Katachi: Decoding the Imprints of Past Star Formation on Present Day Morphology in Galaxies with Interpretable CNNs
Juan Pablo Alfonzo, Kartheik G. Iyer, Masayuki Akiyama +8
The physical processes responsible for shaping how galaxies form and quench over time leave imprints on both the spatial (galaxy morphology) and temporal (star formation history; S…
PHANGS-ML: dissecting multiphase gas and dust in nearby galaxies using machine learning
Dalya Baron, Karin M. Sandstrom, Erik Rosolowsky +25
The PHANGS survey uses ALMA, HST, VLT, and JWST to obtain an unprecedented high-resolution view of nearby galaxies, covering millions of spatially independent regions. The high dim…
Deep Learning Cosmic Ray Transport from Density Maps of Simulated, Turbulent Gas
Chad Bustard, John Wu
The coarse-grained propagation of Galactic cosmic rays (CRs) is traditionally constrained by phenomenological models of Milky Way CR propagation fit to a variety of direct and indi…
How the Galaxy-Halo Connection Depends on Large-Scale Environment
John F. Wu, Christian Kragh Jespersen, Risa H. Wechsler
We investigate the connection between galaxies, dark matter halos, and their large-scale environments at with Illustris TNG300 hydrodynamic simulation data. We predict stella…
A variable active galactic nucleus at triply-imaged by the galaxy cluster MACS J0035.4-2015
Lukas J. Furtak, Ramesh Mainali, Adi Zitrin +32
We report the discovery of a triply imaged active galactic nucleus (AGN), lensed by the galaxy cluster MACS J0035.4-2015 (). The object is detected in Hubble…
Identification of galaxy shreds in large photometric catalogs using Convolutional Neural Networks
Enrico M. Di Teodoro, Josh E. G. Peek, John F. Wu
Contamination from galaxy fragments, identified as sources, is a major issue in large photometric galaxy catalogs. In this paper, we prove that this problem can be easily addressed…
Identifying AGN host galaxies with convolutional neural networks
Ziting Guo, John F. Wu, Chelsea E. Sharon
Active galactic nuclei (AGN) are supermassive black holes with luminous accretion disks found in some galaxies, and are thought to play an important role in galaxy evolution. Howev…
Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program
Elise Darragh-Ford, John F. Wu, Yao-Yuan Mao +39
We introduce the DESI LOW-Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift ta…
Identification of Galaxy-Galaxy Strong Lens Candidates in the DECam Local Volume Exploration Survey Using Machine Learning
E. A. Zaborowski, A. Drlica-Wagner, F. Ashmead +88
We perform a search for galaxy-galaxy strong lens systems using a convolutional neural network (CNN) applied to imaging data from the first public data release of the DECam Local V…
LADUMA: Discovery of a luminous OH megamaser at
Marcin Glowacki, Jordan D. Collier, Amir Kazemi-Moridani +65
In the local Universe, OH megamasers (OHMs) are detected almost exclusively in infrared-luminous galaxies, with a prevalence that increases with IR luminosity, suggesting that they…
Extending the SAGA Survey (xSAGA) I: Satellite Radial Profiles as a Function of Host Galaxy Properties
John F. Wu, J. E. G. Peek, Erik J. Tollerud +6
We present "Extending the Satellites Around Galactic Analogs Survey" (xSAGA), a method for identifying low- galaxies on the basis of optical imaging, and results on the spatial…
