Welcome to the TITAN homepage! 

TITAN is a new low-redshift Type Ia supernova (SN Ia) resource built for the era of precision cosmology. Using data from the ATLAS all-sky survey, TITAN brings together cosmology-grade lightcurves and host-galaxy properties for over 5000 spectroscopically confirmed SNe Ia at z ≲ 0.1, providing the largest sample of low-redshift, spectroscopically confirmed SNe Ia to date. Designed both as a robust nearby anchor for joint analyses with BAO, CMB, LSST and Roman, and as a laboratory for understanding host-galaxy effects such as the SN Ia “mass step”, TITAN aims to rebuild the low-redshift foundation of supernova cosmology.
