ZTF SN Ia DR2 follow-up: early excess in Type Ia supernova light curves
Tomás E. Müller-Bravo, Tomás E. Müller-Bravo, Kate Maguire +17
There is broad consensus that Type Ia supernovae (SNe Ia) are the thermonuclear explosions of C/O white dwarfs (WDs) in binary systems, but their progenitors and explosion mechanis…
Decoding the Early-Time Light Curves of Type Ia Supernovae. II. Population Parameters of One Thousand ZTF Supernovae
Chang Liu, Adam A. Miller, Nikhil Sarin +13
Early-time light curves of Type Ia Supernovae (SNe Ia) encode critical information about their progenitor systems. We characterize the rise of normal SNe Ia using a volume-complete…
An analysis of the Type Ia SN 2024gy and a comparison of different host extinction estimation techniques
Jacco H. Terwel, Kate Maguire, Cillian O'Donnell +38
Type Ia supernovae (SNe Ia) are well-known standardisable candles, and are one of the main ways to measure the distance to their host galaxies. However, extinction due to interstel…
Illuminating the Local Universe: Large-Scale Structure from ZTF Type Ia Supernovae
Antoine Gilles Lordet, Ariel Goobar, Jens Jasche +12
Within the volume-limited subsample at of the Zwicky Transient Facility (ZTF) DR2 sample, we confirm a statistically significant excess of Type Ia supernovae (SNe Ia) at $…
ZTF SN Ia DR2 follow-up: Characterization of subluminous Type Ia supernovae in the ZTF DR2 full sample
Alaa Alburai, LluÃs Galbany, Umut Burgaz +19
The Zwicky Transient Facility Data Release 2 (ZTF DR2) includes a total of 3,628 Type Ia supernovae (SNe~Ia), providing the largest and most complete sample of spectroscopically co…
A real-time search for Type Ia Supernovae with late-time CSM interaction in ZTF
Jacco H. Terwel, Kate Maguire, Seán J. Brennan +20
The nature of Type Ia supernova (SN Ia) progenitor systems and the mechanisms that lead up to their explosions are still widely debated. In rare cases the SN ejecta interact with c…
