SN 2022erq: A Superluminous Thermonuclear Supernova with Escalating Preexplosion Mass Loss
Qian Zhai, Jujia Zhang, Xiaofeng Wang +51
We present a photometric and spectroscopic study of the superluminous Type Ia supernova SN 2022erq. Its early spectra, dominated by iron-group elements with weak intermediate-mass…

Z. -Y. Wang, A. Pastorello, Y. -Z. Cai +53
We present the photometric and spectroscopic analysis of five Type Ibn supernovae (SNe): SN 2020nxt, SN 2020taz, SN 2021bbv, SN 2023utc, and SN 2024aej. These events share key obse…
Detection and Characterization of Quasi-Periodic Oscillations in Seyfert Galaxy NGC 4151
Yan Yongkang, Zhang Peng, Lu Zhou +6
This study aims to detect and characterize quasi-periodic oscillations (QPOs) signals in X-ray observations of NGC 4151. We employed the Weighted Wavelet Z-transform (WWZ) and Lomb…
Quenching and recovery of persistent X-ray emission during a superburst in 4U 182030
Zhijiao Peng, Zhaosheng Li, Yuanyue Pan +6
We report the superburst from 4U 1820--30 in 2021 observed by the Monitor of All-sky X-ray Image and Neutron star Interior Composition Explorer (NICER). During the tail of the supe…
