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…
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.…
AT2019cmw: A highly luminous, cooling featureless TDE candidate from the disruption of a high mass star in an early-type galaxy
Jacob L. Wise, Daniel A. Perley, Nikhil Sarin +23
We present optical/UV photometric and spectroscopic observations, as well as X-ray and radio follow-up, of the extraordinary event AT2019cmw. With a peak bolometric luminosity of ~…
Application of time-series analysis methods to a multiple-sector TESS observations: the case of the radio-loud blazar 3C 371
Ashutosh Tripathi, Paul J. Wiita, Ryne Dingler +4
We present various time series analysis methods to analyze multiple-sector observations of bright AGN from the Transiting Exoplanet Survey Satellite (TESS) and examine whether issu…
Deconvolution for Large Astronomical Surveys: A Study of the Scaled Gradient Projection Method on Zwicky Transient Facility Data
Yash Gondhalekar, Richard M. Feder, Matthew J. Graham +4
Ground-based astronomical observations will continue to produce resolution-limited images due to atmospheric seeing. Deconvolution reverses such effects and thus can benefit extrac…
Joint Modeling of Quasar Variability and Accretion Disk Reprocessing using Latent Stochastic Differential Equations
Joshua Fagin, James Hung-Hsu Chan, Henry Best +5
Quasars are bright active galactic nuclei powered by the accretion of matter around supermassive black holes at the center of galaxies. Their stochastic brightness variability depe…
