Ellipsoidal modulation and multi-wavelength activity in the pre-cataclysmic binary RX J1553.0+4457
S. -Y. Wu, M. Gritsevich, Q. -H. Lao +39
RX J1553.0+4457 (TMTS J15530469+4457458) is a detached post-common-envelope binary containing a cool white dwarf and an active late-type companion. We present a multi-wavelength st…

Stochastic Optical Variability and an rms-flux Relation in the Intermediate Polar EP240309a
S. -Y. Wu, Y. -D. Hu, I. Perez-Garcia +18
Magnetic cataclysmic variables provide a natural laboratory for studying how accretion interacts with compact-object magnetospheres and generates stochastic variability. We present…

Insights into the Long-term behavior of the optical polarization from the blazar 1ES 1959+650
K K Singh, A Singh, A Tolamatti +2
A high degree of linear polarization measured in the optical emission is an important observational feature of blazars. It provides strong evidence of the presence of relativistic…
