ZTF SNe Ia DR2: Towards cosmology-grade ZTF supernova light curves using scene modeling photometry
L. Lacroix, N. Regnault, T. de Jaeger +36
The Zwicky Transient Facility (ZTF) is conducting a wide-field survey of the northern sky in three optical bands and the collaboration cosmology working group has released 3628 spe…
ZTF SN Ia DR2: Improved SN Ia colors through expanded dimensionality with SALT3+
W. D. Kenworthy, A. Goobar, D. O. Jones +24
Type Ia supernovae (SNe Ia) are a key probe in modern cosmology, as they can be used to measure luminosity distances at gigaparsec scales. Models of their light-curves are used to…
ZTF SN Ia DR2: Exploring SN Ia properties in the vicinity of under-dense environments
M. Aubert, P. Rosnet, B. Popovic +29
The unprecedented statistics of detected Type Ia supernovae (SNe Ia) brought by the Zwicky Transient Facility enables us to probe the impact of the Large-Scale Structure on the pro…
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: 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: Impact of the galaxy cluster environment on the stretch distribution of Type Ia supernovae
F. Ruppin, M. Rigault, M. Ginolin +28
Understanding the impact of the astrophysical environment on Type Ia supernova (SN Ia) properties is crucial to minimize systematic uncertainties in cosmological analyses based on…
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…
