EP250827b/SN 2025wkm: An X-ray Flash-Supernova Powered by a Central Engine and Circumstellar Interaction
Gokul P. Srinivasaragavan, Dongyue Li, Xander J. Hall +100
We present the discovery of EP250827b/SN 2025wkm, an X-ray Flash (XRF) discovered by the Einstein Probe (EP), accompanied by a broad-line Type Ic supernova (SN Ic-BL) at $z = 0.119…
An axisymmetric shock breakout indicated by prompt polarized emission from the type II supernova 2024ggi
Yi Yang, Xudong Wen, Lifan Wang +18
The death of massive stars is triggered by an infall-induced bounce shock that disrupts the star. How such a shock is launched and propagates through the star is a decade-long puzz…
SN 2024iss: A Double-peaked Type IIb Supernova with Evidence of Circumstellar Interaction
Liyang Chen, Xiaofeng Wang, Qinyu Wu +54
We present optical, ultraviolet, and X-ray observations of supernova (SN) 2024iss, a Type IIb SN that shows a prominent double-peaked light curve. We modeled the first peak with a…
Spectral Hardening Reveals Afterglow Emergence in Long-Duration Fast X-ray Transients: A Case Study of GRB 250404A/EP250404a
Yi-Han Iris Yin, Yuan Fang, Bin-Bin Zhang +56
The prompt emission and afterglow phases of gamma-ray bursts (GRBs) have been extensively studied, yet the transition between these two phases remains inadequately characterized du…
Investigating the Period-Luminosity Relations of delta Scuti Stars: A Pathway to Distance and 3-D Dust Map Inference
Fangzhou Guo, Joshua S. Bloom, Xiaofeng Wang +12
While delta Scuti stars are the most numerous class of kappa-mechanism pulsators in the instability strip, the short periods and small peak-to-peak amplitudes have left them unders…
Supernovae at Distances < 40 Mpc: II. Supernova Rate in the Local Universe
Xiaoran Ma, Xiaofeng Wang, Jun Mo +21
Context.This is the second paper of a series aiming to determine the birth rates of supernovae in the local Universe. Aims. In this paper, we aim to estimate the SN rates in the lo…
Supernovae at Distances < 40 Mpc: I.Catalogues and fractions of Supernovae in a Complete Sample
Xiaoran Ma, Xiaofeng Wang, Jun Mo +20
Context.This is the first paper of a series aiming to determine the fractions and birth rates of various types of supernovae (SNe) in the local Universe. Aims. In this paper, we ai…
Optical and Near-infrared Observations of SN 2023ixf for over 600 days after the Explosion
Gaici Li, Xiaofeng Wang, Yi Yang +37
Context.We present a comprehensive photometric and spectroscopic study of the nearby Type II supernova (SN) 2023ixf, with our extensive observations spanning the phases from ~3 to…
A post-common-envelope binary with double-peaked Balmer emission lines from TMTS
Qichun Liu, Xiaofeng Wang, Jie Lin +20
The dynamical method provides an efficient way to discover post-common-envelope binaries (PCEB) with faint white dwarfs (WDs), thanks to the development of time-domain survey proje…
Detection of [C I] Emission in Nebular Spectra of a Peculiar Type Ia Supernova 2022pul
Jialian Liu, Xiaofeng Wang, Yi Yang +6
SN 2022pul gains special attention due to its possible origin of a super-Chandarsekhar-mass white dwarf explosion (or called a 03fg-like type Ia supernova), which shows prominent […
SN 2021hpr: A Normal Type Ia Supernova Showing Excess Emission in the Early Rising Phase
Abdusamatjan Iskandar, Xiaofeng Wang, Ali Esamdin +37
We present extensive optical observations of a nearby Type Ia supernova (SN Ia), SN 2021hpr, located in the spiral galaxy NGC 3147 at a distance of 45 Mpc. Our observations…
