ZTF SN Ia DR2: Simulations and volume limited sample

M. Amenouche, M. Smith, P. Rosnet +27

Type Ia supernovae (SNe Ia) constitute an historical probe to derive cosmological parameters through the fit of the Hubble-Lemaître diagram, i.e. SN Ia distance modulus versus thei…

ZTF SN Ia DR2: Overview

Mickael Rigault, Mathew Smith, Ariel Goobar +53

We present the first homogeneous release of several thousand Type Ia supernovae (SNe Ia), all having spectroscopic classification, and spectroscopic redshifts for half the sample.…

ZTF SN Ia DR2: Evidence of Changing Dust Distributions With Redshift Using Type Ia Supernovae

B. Popovic, M. Rigault, M. Smith +29

Type Ia supernova (SNIa) are excellent probes of local distance, and the increasing sample sizes of SNIa have driven an increased need to study the associated systematic uncertaint…

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…

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: Peculiar velocities impact on the Hubble diagram

B. Carreres, D. Rosselli, J. E. Bautista +35

SNe Ia are used to determine the distance-redshift relation and build the Hubble diagram. Neglecting their host-galaxy peculiar velocities (PVs) may bias the measurement of cosmolo…

Accuracy of environmental tracers and consequence for determining the Type Ia Supernovae magnitude step

M. Briday, M. Rigault, R. Graziani +12

Type Ia Supernovae (SNe Ia) are standardizable candles that allow us to measure the recent expansion rate of the Universe. Due to uncertainties in progenitor physics, potential ast…
