The kinematics of ten superluminal components (C11- C16, C18, C20, C21 and C24) of blazar 3C 279 are studied from VLBI observations. It is shown that their init
White-light(WL) flares have been observed and studied for more than a century since their first discovery. However, some fundamental physics behind the brillian
We use recent X-ray observations of the intracluster medium(ICM) of the galaxy group NGC 5813 to confront theoretical studies of ICM thermal evolution with the
We report on the first investigation into kinematics and chromospheric activity of M dwarfs from the Guo Shou Jing Telescope(also called the Large Sky Area Mult
