Transfer learning for galaxy feature detection: Finding Giant Star-forming Clumps in low redshift galaxies using Faster R-CNN
Jürgen Popp, Hugh Dickinson, Stephen Serjeant +8
Giant Star-forming Clumps (GSFCs) are areas of intensive star-formation that are commonly observed in high-redshift (z>1) galaxies but their formation and role in galaxy evolution…
TCuPGAN: A novel framework developed for optimizing human-machine interactions in citizen science
Ramanakumar Sankar, Kameswara Mantha, Lucy Fortson +8
In the era of big data in scientific research, there is a necessity to leverage techniques which reduce human effort in labeling and categorizing large datasets by involving sophis…
Automated 3D Tumor Segmentation using Temporal Cubic PatchGAN (TCuP-GAN)
Kameswara Bharadwaj Mantha, Ramanakumar Sankar, Lucy Fortson
Development of robust general purpose 3D segmentation frameworks using the latest deep learning techniques is one of the active topics in various bio-medical domains. In this work,…
The UV luminosity function at 0.6 < z < 1 from UVCANDELS
Lei Sun, Xin Wang, Harry I. Teplitz +75
UVCANDELS is a HST Cycle-26 Treasury Program awarded 164 orbits of primary ultraviolet (UV) F275W imaging and coordinated parallel optical F435W imaging in four CANDELS fields: GOO…
Optimizing the Wasserstein GAN for TeV Gamma Ray Detection with VERITAS
Deivid Ribeiro, Yuping Zheng, Ramana Sankar +1
The observation of very-high-energy (VHE, E>100 GeV) gamma rays is mediated by the imaging atmospheric Cherenkov technique (IACTs). At these energies, gamma rays interact with the…
Galaxy Zoo DESI: Detailed Morphology Measurements for 8.7M Galaxies in the DESI Legacy Imaging Surveys
Mike Walmsley, Tobias Géron, Sandor Kruk +13
We present detailed morphology measurements for 8.67 million galaxies in the DESI Legacy Imaging Surveys (DECaLS, MzLS, and BASS, plus DES). These are automated measurements made b…
The Lyman Continuum Escape Fraction of Star-forming Galaxies at from UVCANDELS
Xin Wang, Harry I. Teplitz, Brent M. Smith +74
The UltraViolet Imaging of the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey Fields (UVCANDELS) survey is a Hubble Space Telescope (HST) Cycle-26 Treasury Program,…
Harnessing the Hubble Space Telescope Archives: A Catalogue of 21,926 Interacting Galaxies
David O'Ryan, Bruno Merín, Brooke D. Simmons +13
Mergers play a complex role in galaxy formation and evolution. Continuing to improve our understanding of these systems require ever larger samples, which can be difficult (even im…
Galaxy Zoo: Kinematics of strongly and weakly barred galaxies
Tobias Géron, Rebecca J. Smethurst, Chris Lintott +8
We study the bar pattern speeds and corotation radii of 225 barred galaxies, using IFU data from MaNGA and the Tremaine-Weinberg method. Our sample, which is divided between strong…
