Central Engine and Spectral Energy Distribution Properties of High Redshift Gamma Ray Blazars
A. Tolamatti, K. K. Singh, K. K. Yadav
We report on the properties of central engines in the -ray blazars located at high redshifts beyond z~>~0.4, where the extra-galactic background light (EBL) starts affecting the…
On the Maximum Energy Release from Formation of Static Compact Objects
A. Mitra, K. K. Singh
Type II Supernova 1987A (SN 1987A), observed in 1987, released an energy of \mbox{ erg}}. This huge energy is essentially the magnitude of gravitational…
Thermal Radiation from Compact Objects in Curved Space-Time
Abhas Mitra, Krishna Kumar Singh
We highlight here the fact that the distantly observed luminosity of a spherically symmetric compact star radiating thermal radiation isotropically is higher by a factor of $(1+z_{…
Status update of MACE Gamma-ray telescope
HiGRO Collaboration, N Bhatt, S Bhattacharyya +29
MACE (Major Atmospheric Cherenkov Experiment), an imaging atmospheric Cherenkov telescope, has recently been installed by the HiGRO (Himalayan Gamma-Ray Observatory) collaboration…
Results from the long-term Fermi-LAT observations of the white dwarf binary pulsar AR Scorpii
Q. Kaplan, P. J. Meintjes, K. K. Singh +3
The discovery of the white dwarf binary system AR Scorpii (AR Sco) with its fascinating non-thermal dominated multi-frequency emission has sparked renewed interest in potential hig…
A time dependent approach to model X-ray and --ray light curves of Mrk 421 observed during the flare in February 2010
K K Singh, S Sahayanathan, A Sinha +18
Strong X-ray and --ray flares have been detected in February 2010 from the high synchrotron peaked blazar Mrk 421 (z=0.031). With the motivation of understanding the physics inv…
