My datasets
- DECADE shear catalogs and datavectors
- Ulagam simulations
- DELVE DR3
- DES Y6 Balrog
- IllustrisTNG halo structure
- Other data products I often use:
My work produces a variety of datasets from telescope images and also from simulations. Here is a list of some of the dataproducts whose development I led or was heavily involved in, and how to get access to them.
DECADE shear catalogs and datavectors
We’ve made all the DECADE dataproducts available to the public. Please view this page for a detailed listing of the dataproducts, their documentation, and how to access them. There are multiple repositories for accessing the different data. If you don’t see a product you want, please reach out to us! We’re currently working on derived galaxy clustering samples and a galaxy cluster catalog using the coadd data.
Ulagam simulations
The Ulagam simulation suite is set a full-sky N-body simulations that are focused on resolving signatures from primordial physics in the deeply nonlinear regime. The original sims were introduced in Anbajagane+ 2024, and additional sims were added in Anbajagane & Lee 2025a and Anbajagane & Lee 2025b.
DELVE DR3
The DELVE datarelease can be found at Noirlab here. The coadd images, produced as part of the DECADE campaign within DELVE, cover an additional $$14,!000 \,\,{\rm deg}^2$ of sky outside the DES DR2. The catalogs from this coadd processing can be found at this NOIRLab table. The raw images are being uploaded currently.
DES Y6 Balrog
The DES Y6 synthetic source injection (SSI) campaign is the largest dataset at this level of fidelity — every image in the DES Y6 dataset has been reprocessed with synthetic sources injected into the image. The catalogs can be found here and are introduced in Anbajagane+ 2025.
IllustrisTNG halo structure
I’ve generated curated, Rockstar-like catalogs from IllustrisTNG and they are part of TNG’s supplemental data release. These were used in the baryon imprints study of Anbajagane+ 2021.
