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…
A Reassessment of the Pantheon+ and DES 5YR Calibration Uncertainties: Dovekie
B. Popovic, W. D. Kenworthy, M. Ginolin +21
Type Ia Supernovae (SNe Ia) are crucial tools to measure the accelerating expansion of the universe, comprising thousands of SNe across multiple telescopes. Accurate measurements o…
Development of an Ultra-fast, Likelihood-based, Distance Inference Framework for the Next Generation of Type Ia Supernova Surveys
Dylan Kuhn, Marc Betoule
In this work, we present EDRIS (French for Distance Estimator for Incomplete Supernova Surveys), a cosmological inference framework tailored to reconstruct unbiased cosmological di…
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.…
Accurate measurement of telescope filter bandpasses with a Collimated Beam Projector and impact on cosmological parameters
Jérémy Neveu, Dylan Kuhn, Thierry Souverin +1
The measurement of magnitudes with different filters in photometric surveys gives access to cosmological distances and parameters. However, for current and future large surveys lik…
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: 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…
