A Multi-Wavelength View of the First Type Ic-BL Supernova with an Einstein Probe X-ray Shock Breakout

Jillian C. Rastinejad, Gokul Srinivasaragavan, Nikhil Sarin +36

The paper reports multi-wavelength observations of the nearby fast X‑ray transient EP260321a, identified as the shock‑breakout of a broad‑line Type Ic supernova (SN2026gzf), and us…

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…

Multi-year Ground-Based Survey Photometry of Active Comet 103P/Hartley 2 and Centaur (2060) Chiron: A Tale of Two Comets in the Pre-LSST Era

Joseph Murtagh, Megan E. Schwamb, Michael S. P. Kelley +22

Comets and Centaurs trace the evolution of trans-Neptunian objects (TNOs) into the inner solar system. Their activity reflects the interplay between volatile sublimation, dust dyna…

Constraints on Late-Time Flaring from Luminous Fast Blue Optical Transients using the Transiting Exoplanet Survey Satellite and the Zwicky Transient Facility

Rahul Jayaraman, Anna Y. Q. Ho, Michael M. Fausnaugh +14

The Luminous Fast Blue Optical Transient (LFBOT) AT2022tsd exhibited minutes-timescale optical flares in the tens of days following the initial transient event, likely due to a cen…

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…

Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. II: Lightcurve Analysis

Kaustav K. Das, Mansi M. Kasliwal, Jesper Sollerman +18

The Zwicky Transient Facility Census of the Local Universe survey yielded a sample of 330 Type IIP supernovae (SNe) with well-constrained peak luminosities. In paper I (arXiv:2502.…
