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…
Two years of shock interaction tracing three phases of evolution: the explosion of a Type IIn supernova, SN 2019vxm
Gitika Rameshan, Rishabh Singh Teja, D. K. Sahu +10
We present multi-wavelength photometric and optical spectroscopic observations of the long-lived interacting supernova SN 2019vxm, spanning more than two years after the explosion.…
SN 2024dy: Dust formation in a long-lived Type IIn supernova and constraints on the dust mass
Sota Goto, Masayuki Yamanaka, Koji S. Kawabata +10
Type~IIn supernovae (SNe) are a subclass of core-collapse SNe powered by interaction between the ejecta and the dense circumstellar material. Among them, long-lived Type~IIn events…
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.…
Low-Luminosity Type IIP Supernovae from the Zwicky Transient Facility Census of the Local Universe. I: Luminosity Function, Volumetric Rate
Kaustav K. Das, Mansi M. Kasliwal, Christoffer Fremling +51
We present the luminosity function and volumetric rate of a sample of Type IIP supernovae (SNe) from the Zwicky Transient Facility Census of the Local Universe survey (CLU). This i…
AT2024wpp: An Extremely Luminous Fast Ultraviolet Transient Powered by Accretion onto a Black Hole
Daniel A. Perley, Anna Y. Q. Ho, Zoë McGrath +69
We present the discovery of AT 2024wpp ("Whippet"), a fast and luminous 18cow-like transient. At a redshift of z=0.0868, revealed by Keck Cosmic Web Imager spectroscopy of its fain…
