We study the relationship between isophotal shapes,central light profiles and kinematic properties of early-type galaxies(ETGs) based on a compiled sample of184
We study the γ-ray luminosity and beaming effect for Fermi blazars.Our results are as follows.(i) There are significant correlations between γ-ray luminosity an
The Ultra Violet Imaging Telescope(UVIT) is one of the payloads on the first Indian multiwavelength satellite ASTROSAT,which is expected to be launched by the I
By linear perturbation theory, a sensitivity study is presented to calculate the contribution of the Mars gravity field to the orbital perturbations in velocity
HD 49798(a hydrogen depleted subdwarf O6 star) with its massive white dwarf(WD) companion has been suggested to be a progenitor candidate of a type Ia supernova
Previous works suggested that the state transitions in an X-ray binary can be triggered by accreting an inverse magnetic field from its companion star. A key po
