SN 2025dys: A luminous supernova explosion from a partially stripped helium star
Jiewei Zhao, Brajesh Kumar, Gitika Rameshan +25
We present well-sampled multi-band imaging and low- to medium-resolution spectroscopic observations of the early-discovered Type~II supernova (SN)~2025dys. The photometric evolutio…
Simultaneous Real-Color Time-Domain Survey of the Coma Field with the Multi-channel Photometric Survey Telescope (Mephisto)
Yu Pan, Yuan-Pei Yang, Ye-Hao Cheng +25
We present the results from a high-cadence, multi-channel time-domain survey targeting the Coma galaxy cluster, utilizing the newly commissioned 1.6-m Multi-channel Photometric Sur…
Atmospheric Parameter Determination of RR Lyrae Stars With Mephisto Multi-band Photometry
Xingzhu Zou, Maosheng Xiang, Tanda Li +18
Phase-resolved atmospheric parameters of pulsating stars, including RR Lyrae stars and Cepheids, are essential for studying stellar structure and pulsation physics and for establis…
Early Near-Infrared Excess and Rapid Disk-Corona Evolution in the Tidal Disruption Event 2024aepd
Yongxin Wu, Yanan Wang, Thomas M. Reynolds +38
We present multi-wavelength observations of the tidal disruption event (TDE) 2024aepd, spanning primarily the first 300 days after discovery. A prominent near-infrared (NIR)…
Fitting the light curves of tidal disruption events with non-parabolic model
Shiyan Zhong, Chenxi Shang, Xiaowei Liu
Tidal disruption events (TDEs) are powerful probes of supermassive black hole (SMBH) properties and accretion physics. The existing light curve fitting tools assume that the disrup…
SN 2024aecx: A double-peaked rapidly evolving Type IIb supernova at 11 Mpc
Xingzhu Zou, Brajesh Kumar, Rishabh Singh Teja +28
We present the results of low-resolution spectroscopic and densely sampled multi-band photometric follow-up of supernova (SN) 2024aecx. The SN was discovered in the spiral galaxy N…
Modeling the UV/Optical light curve of re-brightening tidal disruption events
Shiyan Zhong
In recent years, a new subclass of tidal disruption events (TDEs) was reported from the literature. The light curve of these TDEs show a re-brightening feature in the decline phase…
Black hole mass and optical radiation mechanism of the tidal disruption event AT 2023clx
Shiyan Zhong, Xian Xu, Xinlei Chen +5
We present the optical light curves of the tidal disruption event (TDE) AT 2023clx in the declining phase, observed with Mephisto. Combining our light curve with the ASAS-SN and AT…
Early-phase simultaneous multiband observations of the Type II supernova SN 2024ggi with Mephisto
Xinlei Chen, Brajesh Kumar, Xinzhong Er +24
We present early-phase good-cadence (hour-to-day) simultaneous multiband ( and bands) imaging of the nearby supernova SN~2024ggi, which exploded in the nearby galaxy, NG…
Gleeok's Fire-breathing: Triple Flares of AT 2021aeuk within Five Years from the Active Galaxy SDSS J161259.83+421940.3
Dong-Wei Bao, Wei-Jian Guo, Zhi-Xiang Zhang +12
We present a noteworthy transient AT 2021aeuk exhibiting three distinct optical flares between 2018 and 2023. It is hosted in a radio-loud narrow-line Seyfert 1 (NLSy1) galaxy, wit…
