A DECADE of dwarfs: first detection of weak lensing around spectroscopically confirmed low-mass galaxies

Chun-Hao To, Chihway Chang, Dhayaa Anbajagane +35

We present the first detection of weak gravitational lensing around spectroscopically confirmed dwarf galaxies, using the large overlap between DESI DR1 spectroscopic data and DECA…

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…

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…

The impact of spectroscopic incompleteness in direct calibration of redshift distributions for weak lensing surveys

W. G. Hartley, C. Chang, S. Samani +74

Obtaining accurate distributions of galaxy redshifts is a critical aspect of weak lensing cosmology experiments. One of the methods used to estimate and validate redshift distribut…

Stellar Streams Discovered in the Dark Energy Survey

N. Shipp, A. Drlica-Wagner, E. Balbinot +80

We perform a search for stellar streams around the Milky Way using the first three years of multi-band optical imaging data from the Dark Energy Survey (DES). We use DES data cover…
