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…

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…

A galaxy-driven model of type Ia supernova luminosity variations

P. Wiseman, M. Vincenzi, M. Sullivan +59

Type Ia supernovae (SNe Ia) are used as standardisable candles to measure cosmological distances, but differences remain in their corrected luminosities which display a magnitude s…

There is no universal acceleration scale in galaxies

Man Ho Chan, Shantanu Desai, Antonino Del Popolo

Recently, many studies seem to reveal the existence of some correlations between dark matter and baryonic matter. In particular, the unexpected tight Radial Acceleration Relation (…

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…
