Cosmological shocks around galaxy clusters: A coherent investigation with DES, SPT & ACT

D. Anbajagane, C. Chang, E. J. Baxter +111

We search for signatures of cosmological shocks in gas pressure profiles of galaxy clusters using the cluster catalogs from three surveys: the Dark Energy Survey (DES) Year 3, the…

Timing the r-Process Enrichment of the Ultra-Faint Dwarf Galaxy Reticulum II

Joshua D. Simon, Thomas M. Brown, Burçin Mutlu-Pakdil +65

The ultra-faint dwarf galaxy Reticulum II (Ret II) exhibits a unique chemical evolution history, with 72 +10/-12% of its stars strongly enhanced in r-process elements. We present d…

A Sample of Dust Attenuation Laws for DES Supernova Host Galaxies

J. Duarte, S. González-Gaitán, A. Mourao +58

Type Ia supernovae (SNe Ia) are useful distance indicators in cosmology, provided their luminosity is standardized by applying empirical corrections based on light-curve properties…

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…

OzDES Reverberation Mapping Program: H lags from the 6-year survey

Umang Malik, Rob Sharp, A. Penton +64

Reverberation mapping measurements have been used to constrain the relationship between the size of the broad-line region and luminosity of active galactic nuclei (AGN). This …

Characterising the Intracluster Light over the Redshift Range in the DES-ACT Overlap

Jesse B. Golden-Marx, Y. Zhang, R. L. C. Ogando +66

We characterise the properties and evolution of Bright Central Galaxies (BCGs) and the surrounding intracluster light (ICL) in galaxy clusters identified in overlapping regions of…

Lessons Learned from the Two Largest Galaxy Morphological Classification Catalogues built by Convolutional Neural Networks

Ting-Yun Cheng, H. Domínguez Sánchez, J. Vega-Ferrero +54

We compare the two largest galaxy morphology catalogues, which separate early and late type galaxies at intermediate redshift. The two catalogues were built by applying supervised…

Optical Variability of Quasars with 20-Year Photometric Light Curves

Zachary Stone, Yue Shen, Colin J. Burke +52

We study the optical photometric variability of a sample of 190 quasars within the SDSS Stripe 82 region that have long-term photometric coverage during with…

From the Fire: A Deeper Look at the Phoenix Stream

K. Tavangar, P. Ferguson, N. Shipp +64

We use six years of data from the Dark Energy Survey to perform a detailed photometric characterization of the Phoenix stellar stream, a 15-degree long, thin, dynamically cold, low…
