Two-population model of type Ia supernovae and their associations with host galaxies in ZTF DR2
Radosław Wojtak, Lucas Hallgren, Jens Hjorth
We constrain type Ia supernova intrinsic properties, extinction, and probabilistic supernova-host associations using the volume-limited sample from the Zwicky Transient Factory DR2…

Diverse reddening distributions in sight lines to type Ia supernovae
Lucas Hallgren, Radoslaw Wojtak, Jens Hjorth +1
Precise cosmological constraints from type Ia supernovae require adequately accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the proble…
