Constraining Type Ia supernova explosions and early flux excesses with the Zwicky Transient Factory
M. Deckers, K. Maguire, M. R. Magee +14
In the new era of time-domain surveys Type Ia supernovae are being caught sooner after explosion, which has exposed significant variation in their early light curves. Two driving f…

The Effect of Environment on Type Ia Supernovae in the Dark Energy Survey Three-Year Cosmological Sample
L. Kelsey, M. Sullivan, M. Smith +73
Analyses of type Ia supernovae (SNe Ia) have found puzzling correlations between their standardised luminosities and host galaxy properties: SNe Ia in high-mass, passive hosts appe…
Weak Lensing of Type Ia Supernovae from the Dark Energy Survey

We consider the effects of weak gravitational lensing on observations of 196 spectroscopically confirmed Type Ia Supernovae (SNe Ia) from years 1 to 3 of the Dark Energy Survey (DE…
Redshift evolution of the underlying type Ia supernova stretch distribution
N. Nicolas, M. Rigault, Y. Copin +7
The detailed nature of type Ia supernovae (SNe Ia) remains uncertain, and as survey statistics increase, the question of astrophysical systematic uncertainties arises, notably that…
Supernova Siblings: Assessing the Consistency of Properties of Type Ia Supernovae that Share the Same Parent Galaxies
D. Scolnic, M. Smith, A. Massiah +82
While many studies have shown a correlation between properties of the light curves of Type Ia SN (SNe Ia) and properties of their host galaxies, it remains unclear what is driving…
