The Milky Way-like radial structure in nearby galaxies

Yuze Zhao, Jianhui Lian, Zheng Zheng +16

The Milky Way exhibits a distinctive plateau in its inner surface brightness profile around one effective radius, challenging the traditional view of a purely exponential disk. To…

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…

Rapid Variability and Broadband Spectral Modeling in the Flaring Activity of BL Lacertae

Xin Chang, Dingrong Xiong, Chenxu Liu +17

We report a multi-wavelength study of two flaring episodes of the blazar BL Lacertae during MJD 60500-60800 (9 July 2024 - 5 May 2025). The source reached a daily-averaged -ray…
