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…
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…
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…
Comparing the DES-SN5YR and Pantheon+ SN cosmology analyses: Investigation based on "Evolving Dark Energy or Supernovae systematics?"
M. Vincenzi, R. Kessler, P. Shah +65
Recent cosmological analyses measuring distances of Type Ia Supernovae (SNe Ia) and Baryon Acoustic Oscillations (BAO) have all given similar hints at time-evolving dark energy. To…
