ZTF-SEDm Type Ia supernova sample for Twins Embedding spectrophotometric standardization
C. Ganot, Y. Copin, M. Rigault +26
This paper has two aims: the first aim is to build a large homogeneous spectrophotometric sample of Type Ia supernovae (SNe Ia), using 3069 spectra from the second data release of…
The Dark Energy Survey Supernova Program: A Reanalysis Of Cosmology Results And Evidence For Evolving Dark Energy With An Updated Type Ia Supernova Calibration
B. Popovic, P. Shah, W. D. Kenworthy +80
We present improved cosmological constraints from a re-analysis of the Dark Energy Survey (DES) 5-year sample of Type Ia supernovae (DES-SN5YR). This re-analysis includes an improv…
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 follow-up: Exploring the origin of the Type Ia supernova host galaxy step through Si II velocities
U. Burgaz, K. Maguire, L. Galbany +18
The relationship between Type Ia supernovae (SNe Ia) and their host galaxy stellar masses is well documented. In particular, Hubble residuals display a luminosity shift based on ho…
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…
Euclid: Quick Data Release (Q1) -- Photometric studies of known transients
C. Duffy, E. Cappellaro, M. T. Botticella +174
We report on serendipitous Euclid observations of previously known transients, using the Euclid Q1 data release. By cross-matching with the Transient Name Server (TNS) we identify…
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: 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 t…
