ZTF SN Ia DR2: Environmental dependencies of stretch and luminosity of a volume limited sample of 1,000 Type Ia Supernovae
M. Ginolin, M. Rigault, M. Smith +43
To get distances, Type Ia Supernovae magnitudes are corrected for their correlation with lightcurve width and colour. Here we investigate how this standardisation is affected by th…
ZTF SN Ia DR2: High-velocity components in the Si II 6355
L. Harvey, K. Maguire, U. Burgaz +27
The ZTF SN Ia Data Release 2 provides a perfect opportunity to perform a thorough search for, and subsequent analysis of, high-velocity components in the Si II 6355 feature in…
ZTF SN Ia DR2: Colour standardisation of Type Ia Supernovae and its dependence on environment
M. Ginolin, M. Rigault, Y. Copin +37
As type Ia supernova (SN Ia) cosmology transitions from a statistics-dominated to a systematics-dominated era, it is crucial to understand the remaining unexplained uncertainties t…
ZTF SN Ia DR2: Properties of the low-mass host galaxies of Type Ia supernovae in a volume-limited sample
U. Burgaz, K. Maguire, G. Dimitriadis +25
In this study, we explore the characteristics of `low-mass' () and `intermediate-mass' () host galaxies o…
ZTF SN Ia DR2: Study of Type Ia Supernova lightcurve fits
M. Rigault, M. Smith, N. Regnault +34
Type Ia supernova (SN Ia) cosmology relies on the estimation of lightcurve parameters to derive precision distances that leads to the estimation of cosmological parameters. The emp…
