The Art of Measuring Physical Parameters in Galaxies: A Critical Assessment of Spectral Energy Distribution Fitting Techniques
Camilla Pacifici, Kartheik G. Iyer, Bahram Mobasher +52
The study of galaxy evolution hinges on our ability to interpret multi-wavelength galaxy observations in terms of their physical properties. To do this, we rely on spectral energy…
From fat droplets to floating forests: cross-domain transfer learning using a PatchGAN-based segmentation model
Kameswara Bharadwaj Mantha, Ramanakumar Sankar, Yuping Zheng +11
Many scientific domains gather sufficient labels to train machine algorithms through human-in-the-loop techniques provided by the Zooniverse.org citizen science platform. As the ra…
A spatially resolved analysis of star-formation burstiness by comparing UV and H in galaxies at z1 with UVCANDELS
Vihang Mehta, Harry I. Teplitz, Claudia Scarlata +30
The UltraViolet imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) program provides HST/UVIS F275W imaging for four CANDELS fields. We…
Galaxy Zoo: Clump Scout -- Design and first application of a two-dimensional aggregation tool for citizen science
Hugh Dickinson, Dominic Adams, Vihang Mehta +9
Galaxy Zoo: Clump Scout is a web-based citizen science project designed to identify and spatially locate giant star forming clumps in galaxies that were imaged by the Sloan Digital…
Optimized Photometric Redshifts for the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS)
Dritan Kodra, Brett H. Andrews, Jeffrey A. Newman +27
We present the first comprehensive release of photometric redshifts (photo-z's) from the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) team. We use stati…
Investigating the Effect of Galaxy Interactions on Star Formation at 0.5<z<3.0
Ekta A. Shah, Jeyhan S. Kartaltepe, Christina T. Magagnoli +24
Observations and simulations of interacting galaxies and mergers in the local universe have shown that interactions can significantly enhance the star formation rates (SFR) and fue…
Identifying Galaxy Mergers in Simulated CEERS NIRCam Images using Random Forests
Caitlin Rose, Jeyhan S. Kartaltepe, Gregory F. Snyder +23
Identifying merging galaxies is an important - but difficult - step in galaxy evolution studies. We present random forest classifications of galaxy mergers from simulated JWST imag…
Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
Jorge A. Zavala, Veronique Buat, Caitlin M. Casey +121
Lyman Break Galaxy (LBG) candidates at z>10 are rapidly being identified in JWST/NIRCam observations. Due to the (redshifted) break produced by neutral hydrogen absorption of rest-…
A Long Time Ago in a Galaxy Far, Far Away: A Candidate z ~ 12 Galaxy in Early JWST CEERS Imaging
Steven L. Finkelstein, Micaela B. Bagley, Pablo Arrabal Haro +117
We report the discovery of a candidate galaxy with a photo-z of z~12 in the first epoch of the JWST Cosmic Evolution Early Release Science (CEERS) Survey. Following conservative se…
Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups
Maxwell Kuschel, Claudia Scarlata, Vihang Mehta +36
We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the…
