January 2024: Data from the Big Sobol Sequence (BSQ), a collection of 32,768 N-body simulations varying 5 cosmological parameters (\(\Omega_{\rm m}\), \(\Omega_{\rm b}\), \(h\), \(n_s\), \(\sigma_8\)) is made publicly available. See Big Sobol Sequence for details.

January 2024: Interested in modified gravity? Check Modified Gravity for Quijote-MG, a set of 4,048 N-body simulations with modified gravity.

November 2023: The Sancho suite, a collection of 240,000 galaxy mock catalogs in redshift-space spanning across 11 cosmologies, 3 massive neutrino cosmologies, 6 primordial non-Gaussianity amplitudes, and 11 Halo Occupation Distribution (HOD) models (together with their corresponding power spectra and bispectra) is now publicly available. Check Sancho Suite for details.

October 2023: Quijote now contains FoF halo catalogs that include the IDs of the particles belonging to the different halos. Check Halo catalogs for details.

September 2023: Data from the Ulagam simulations is made publicly available. Check the Ulagam website for details.

July 2023: We release Gigantes: the largest collection of detailed void catalog created to-date. Check the Gigantes website for details.

July 2023: We have run Rockstar on the Quijote snapshots and all the halo catalogs are publicly available. The rockstar catalogs are located in the New York cluster. Check Data access for details.

June 2023: We have created a series of tutorial to facilitate the usage of Quijote data. Check out Tutorials for details.

June 2023: We release Quijote-ODD, a collection of 1,000 N-body simulations with parity-violation initial conditions. We also make publicly available the FoF and Rockstar halo catalogs generated from these simulations. Check Parity-violation for more details.

March 2023: All data located in the Princeton cluster has been moved to the New York cluster. This means that all Quijote data is now accessible through binder. The Quijote snapshots have also being compressed by Lehman Garrison.

February 2023: We are moving all data located in Princeton to the cluster in New York. You may find some files temporarily missing. We are also compressing all Quijote snapshots due to storage limitations. You can still read the data with Pylians3, but if you are using hdf5 you need to use the hdf5plugin module to deal with the compression. See Snapshots for more details.

December 2022: We have created 3D matter overdensity grids for all PNG simulations and made them publicly available. Data can be accessed through Globus and binder.

October 2022: All the halo catalogs of the primordial non-Gaussianities simulations are now publicly available. Check Primordial non-Gaussianities for more details.

September 2022: All Quijote data located in the San Diego and New York clusters (almost 800 Terabytes) can now be accessed via Binder, a system that allows reading and manipulating the data without having to download it. Check Data access for further details.

July 2022: The snapshots of Quijote-PNG are now publicly available. Check Primordial non-Gaussianities for more details.

June 2022: The nwLH latin-hypercube, containing 2,000 simulations varying \(\Omega_{\rm m}\), \(\Omega_{\rm b}\), \(h\), \(n_s\), \(\sigma_8\), \(M_\nu\), \(w\) is now publicly available! Check Latin-hypercubes for more details.
