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…
Catching Disguised Transients with ASTRANet: Anomaly-Aware Spectroscopic Classification and Conformal Calibration
Argyro Sasli, Maojie Xu, Alexandra Junell +21
Time-domain surveys discover thousands of transients per year, but the spectroscopic identification of rare and physically peculiar objects remains rate-limited by closed-set class…
Leveraging Multimodality for Real-Time Classification of Transients and Variables found by the Zwicky Transient Facility
Ved G. Shah, Nabeel Rehemtulla, Adam A. Miller +13
Modern time-domain surveys such as the Zwicky Transient Facility (ZTF) generate hundreds of thousands of alerts each night, making real-time decisions for follow-up observations a…
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…
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 $…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
