Ultra-Faint Milky Way Satellites Discovered in Carina, Phoenix, and Telescopium with DELVE Data Release 3

C. Y. Tan, W. Cerny, A. B. Pace +76

We report the discovery of three Milky Way satellite candidates: Carina IV, Phoenix III, and DELVE 7, in the third data release of the DECam Local Volume Exploration survey (DELVE)…

Robust Measurement of Stellar Streams Around the Milky Way: Correcting Spatially Variable Observational Selection Effects in Optical Imaging Surveys

K. K. Boone, P. S. Ferguson, M. Tabbutt +47

Observations of density variations in stellar streams are a promising probe of low-mass dark matter substructure in the Milky Way. However, survey systematics such as variations in…

DELVE Milky Way Satellite Galaxy Census I: Satellite Population and Survey Selection Function in DES, DELVE, and Pan-STARRS

C. Y. Tan, A. Drlica-Wagner, A. B. Pace +84

The properties of Milky Way satellite galaxies have important implications for galaxy formation, reionization, and the fundamental physics of dark matter. However, the population o…

DESI EDR: Calibrating the Tully-Fisher Relationship with the DESI Peculiar Velocity Survey

K. Douglass, S. BenZvi, N. Uberoi +45

We calibrate the Tully-Fisher relation (TFR) with data from the DESI Peculiar Velocity (PV) Survey taken during the Survey Validation (SV) period of the DESI galaxy redshift survey…

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…

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…

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…

The Host Galaxies of Rapidly Evolving Transients in the Dark Energy Survey

P. Wiseman, M. Pursiainen, M. Childress +72

Rapidly evolving transients (RETs), also termed fast blue optical transients (FBOTs), are a distinct class of astrophysical event. They are characterised by lightcurves that declin…
