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…
The homogeneity of chemical abundances in H II regions of the Magellanic Clouds
G. Domínguez-Guzmán, M. Rodríguez, J. García-Rojas +3
We use very deep spectra obtained with the Ultraviolet-Visual Echelle Spectrograph at the Very Large Telescope to derive physical conditions and chemical abundances of four H II re…
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…
Euclid preparation. XXV. The Euclid Morphology Challenge -- Towards model-fitting photometry for billions of galaxies
Euclid Collaboration, E. Merlin, M. Castellano +218
The ESA Euclid mission will provide high-quality imaging for about 1.5 billion galaxies. A software pipeline to automatically process and analyse such a huge amount of data in real…
Stellar Populations in type Ia supernova host galaxies at intermediate-high redshift: Star formation and metallicity enrichment histories
I. Millan-Irigoyen, M. G. del Valle-Espinosa, R. Fernández-Aranda +5
We present a summary of our project that studies galaxies hosting type Ia supernova (SN Ia) at different redshifts. We present Gran Telescopio de Canarias (GTC) optical spectroscop…
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…
OzDES Reverberation Mapping Program: Mg II Lags and R-L relation
Zhefu Yu, Paul Martini, A. Penton +55
The correlation between the broad line region radius and continuum luminosity ( relation) of active galactic nuclei (AGN) is critical for single-epoch mass estimates of superm…
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…
Mass-Metallicity and Star Formation Rate in Galaxies: a complex relation tuned to stellar age
S. Duarte Puertas, J. M. Vilchez, J. Iglesias-Páramo +5
In this work we study the stellar mass -- metallicity relation (MZR) of an extended sample of star-forming galaxies in the local Universe and its possible dependence with the star…
Euclid preparation. XXI. Intermediate-redshift contaminants in the search for galaxies within the Euclid Deep Survey
Euclid Collaboration, S. E. van Mierlo, K. I. Caputi +203
(Abridged) The Euclid mission is expected to discover thousands of z>6 galaxies in three Deep Fields, which together will cover a ~40 deg2 area. However, the limited number of Eucl…
Predicting interstellar radiation fields from chemical evolution models
Mario Romero, Pablo Corcho-Caballero, Iker Millán-Irigoyen +2
We present a self-consistent prediction of the interstellar radiation field (ISRF), from the extreme ultraviolet (EUV) to sub-mm range, based on two chemical evolution models of a…
The Evolution of AGN Activity in Brightest Cluster Galaxies
T. Somboonpanyakul, M. McDonald, A. Noble +73
We present the results of an analysis of Wide-field Infrared Survey Explorer (WISE) observations on the full 2500 deg^2 South Pole Telescope (SPT)-SZ cluster sample. We describe a…
The PAU Survey: Measurements of the 4000 Å spectral break with narrow-band photometry
Pablo Renard, Małgorzata Siudek, Martin B. Eriksen +19
The D4000 spectral break index is one of the most important features in the visible spectrum, as it is a proxy for stellar ages and is also used in galaxy classification. However,…
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…
