Dark Energy Survey Year 3 results: Simulation-based CDM inference from weak lensing and galaxy clustering maps with deep learning: Analysis design
A. Thomsen, J. Bucko, T. Kacprzak +99
Data-driven approaches using deep learning are emerging as powerful techniques to extract non-Gaussian information from cosmological large-scale structure. This work presents the f…
A test of invariance of halo surface density for FIRE-2 simulations with cold dark matter and self-interacting dark matter
Sujit K. Dalui, Shantanu Desai
Numerous observations have shown that the dark matter halo surface density, defined as the product of core radius and halo central density of cored dark matter haloes is nearly con…
Testing the cosmic distance duality relation using model-independent approach
Shubham Barua, Sujit K. Dalui, Rikiya Okazaki +1
In this work, we test the cosmic distance duality relation (CDDR) using the arbitrary redshift pivot Padé-(2,1) expansion methodology developed in arXiv:2509.16196. This approach a…
Biasing from galaxy trough and peak profiles with the DES Y3 redMaGiC galaxies and the weak lensing mass map
Q. Hang, N. Jeffrey, L. Whiteway +83
We measure the correspondence between the distribution of galaxies and matter around troughs and peaks in the projected galaxy density, by comparing \texttt{redMaGiC} galaxies ($0.…
Cosmological Constraints on Neutrino Masses in a Second-Order CPL Dark Energy Model
Shubham Barua, Shantanu Desai
Recent DESI results indicate a strong preference for dynamical dark energy (DE) when baryon acoustic oscillation (BAO) measurements are combined with supernovae (SNe) and cosmic mi…
Constraints on Dark Energy Models Using Late Universe Probes
Shubham Barua, Shantanu Desai
We use late Universe probes - Type Ia Supernovae from the PantheonPlus compilation, Quasars, and Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) BAO data - along w…
Comparison of and CDM using DESI DR1 measurements
Kunj Panchal, Shantanu Desai
We use DESI DR1 BAO measurements of the ratio of tranvserse comoving distance to Hubble distance in order to test the compatibility of over flat CDM. For this purpose,…
Dark Energy Survey Year 3 results: CDM cosmology from simulation-based inference with persistent homology on the sphere
J. Prat, M. Gatti, C. Doux +94
We present cosmological constraints from Dark Energy Survey Year 3 (DES Y3) weak lensing data using persistent homology, a topological data analysis technique that tracks how featu…
Selection Function of Clusters in Dark Energy Survey Year 3 Data from Cross-Matching with South Pole Telescope Detections
S. Grandis, M. Costanzi, J. J. Mohr +52
Galaxy clusters selected based on overdensities of galaxies in photometric surveys provide the largest cluster samples. Yet modeling the selection function of such samples is compl…
High-Significance Detection of Correlation Between the Unresolved Gamma-Ray Background and the Large Scale Cosmic Structure
B. Thakore, M. Negro, M. Regis +96
Our understanding of the -ray sky has improved dramatically in the past decade, however, the unresolved -ray background (UGRB) still has a potential wealth of information abo…
Dark Energy Survey Year 6 Results: Point-spread Function Modeling
T. Schutt, M. Jarvis, A. Roodman +70
We present the point-spread function (PSF) modeling for weak lensing shear measurement using the full six years of the Dark Energy Survey (DES Y6) data. We review the PSF estimatio…
Dark Energy Survey Year 6 Results: Synthetic-source Injection Across the Full Survey Using Balrog
D. Anbajagane, M. Tabbutt, J. Beas-Gonzalez +79
Synthetic source injection (SSI), the insertion of sources into pixel-level on-sky images, is a powerful method for characterizing object detection and measurement in wide-field, a…
Dark Energy Survey Year 6 Results: Cell-based Coadds and Metadetection Weak Lensing Shape Catalogue
M. Yamamoto, M. R. Becker, E. Sheldon +81
We present the Metadetection weak lensing galaxy shape catalogue from the six-year Dark Energy Survey (DES Y6) imaging data. This dataset is the final release from DES, spanning 44…
