The Dark Energy Camera All Data Everywhere cosmic shear project V: Constraints on cosmology and astrophysics from 270 million galaxies across 13,000 deg of the sky
D. Anbajagane, C. Chang, A. Drlica-Wagner +78
The paper presents cosmological and astrophysical constraints derived from cosmic shear measurements of 270 million galaxies covering 13,000 deg², combining data from the DECADE pr…
Do Vision-Language Models See Dwarf Galaxies the Way We Do?
Dimitrios Tanoglidis, Chin Yi Tan, Kate Overdeck +1
With the advent of powerful, general-purpose vision-language models (VLMs), there has been growing interest in their potential to assist astronomical discovery, a field characteriz…
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)…
The DECADE cosmic shear project IV: cosmological constraints from 107 million galaxies across 5,400 deg of the sky
D. Anbajagane, C. Chang, A. Drlica-Wagner +72
We present cosmological constraints from the Dark Energy Camera All Data Everywhere (DECADE) cosmic shear analysis. This work uses shape measurements for 107 million galaxies measu…
The DECADE cosmic shear project III: validation of analysis pipeline using spatially inhomogeneous data
D. Anbajagane, C. Chang, N. Chicoine +50
We present the pipeline for the cosmic shear analysis of the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog consisting of 107 million galaxies obse…
The DECADE cosmic shear project II: photometric redshift calibration of the source galaxy sample
D. Anbajagane, A. Alarcon, R. Teixeira +50
We present the photometric redshift characterization and calibration for the Dark Energy Camera All Data Everywhere (DECADE) weak lensing dataset: a catalog of 107 million galaxies…
