While gravitational lensing is believed to provide the most accurate galaxy cluster mass estimates,it is a technique limited to the more local universe.
Nearly 15 ? 20% of solar type stars contain one or more gas giant planet.According to the core-accretion scenario,the acquisition of their gaseous envelope must be preceded by the formation of super-c
Protostellar jets and outflows are an essential component in the star formation process.They regulate the rotating collapse of a star forming cloud into a young star by removing excess angular momentu
Interpreting ultraviolet-to-infrared observations of distant galaxies in terms of constraints on physical parameters-such as stellar mass,star formation rate (SFR) and attenuation by dust-requires spe
A semi-analytical scheme is presented to study general relativistic magnetohydrodynamic (GRMHD) flow along a black hole-threading field line,under the magnetic dominated case.
During the summer on the South Pole of Mars,carbon dioxide geysers loft dust and dirt through cracks in the thawing carbon dioxide ice sheet to the surface where it is believed the surface winds subse
We present the time-frequency analysis results from Hilbert-Huang transform (HHT) for the evolution of a 4 Hz low-frequency quasi-periodic oscillation (LFQPO) around the black hole X-ray binary XTE J1
