Constraining the Stellar-to-Halo Mass Relation with Galaxy Clustering and Weak Lensing from DES Year 3 Data

G. Zacharegkas, C. Chang, J. Prat +100

We develop a framework to study the relation between the stellar mass of a galaxy and the total mass of its host dark matter halo using galaxy clustering and galaxy-galaxy lensing…

Discovering Strong Gravitational Lenses in the Dark Energy Survey with Interactive Machine Learning and Crowd-sourced Inspection with Space Warps

J. Gonzalez, P. Holloway, T. Collett +70

We conduct a search for strong gravitational lenses in the Dark Energy Survey (DES) Year 6 imaging data. We implement a pre-trained Vision Transformer (ViT) for our machine learnin…

The Hierarchical Growth of Bright Central Galaxies and Intracluster Light as Traced by the Magnitude Gap

Jesse B. Golden-Marx, Y. Zhang, R. L. C. Ogando +48

Using a sample of 2800 galaxy clusters identified in the Dark Energy Survey across the redshift range , we characterize the hierarchical assembly of Bright Central…

Weak Gravitational Lensing around Low Surface Brightness Galaxies in the DES Year 3 Data

N. Chicoine, J. Prat, G. Zacharegkas +102

We present galaxy-galaxy lensing measurements using a sample of low surface brightness galaxies (LSBGs) drawn from the Dark Energy Survey Year 3 (Y3) data as lenses. LSBGs are diff…

OzDES Reverberation Mapping Program: Stacking analysis with H, Mg II and C IV

Umang Malik, Rob Sharp, A. Penton +47

Reverberation mapping is the leading technique used to measure direct black hole masses outside of the local Universe. Additionally, reverberation measurements calibrate secondary…

Environmental Quenching of Low Surface Brightness Galaxies near Milky Way mass Hosts

J. Bhattacharyya, A. H. G. Peter, P. Martini +48

Low Surface Brightness Galaxies (LSBGs) are excellent probes of quenching and other environmental processes near massive galaxies. We study an extensive sample of LSBGs near massiv…

Chemical Analysis of the Brightest Star of the Cetus II Ultra-Faint Dwarf Galaxy Candidate

K. B. Webber, T. T. Hansen, J. L. Marshall +42

We present a detailed chemical abundance analysis of the brightest star in the ultra-faint dwarf (UFD) galaxy candidate Cetus II from high-resolution Magellan/MIKE spectra. For thi…
