A prelude to Neutron Stars: The phase diagram of the strong interactions at finite density
Vikram Soni, Dipankar Bhattacharya
We consider strong interactions at finite density in mean field theory, through an effective lagrangian that can describe both nuclear matter and quark matter. This lagrangian has…
SN 2002ap, the hypernova of class Ic
S. B. Pandey, D. K. Sahu, G. C. Anupama +2
The supernova SN 2002ap was discovered in the outer regions of the nearby spiral M74 on January 29.4 UT. Early photometric and spectroscopic observations indicate the supernova bel…
Evolution of an afterglow with a hard electron spectrum
D Bhattacharya, L Resmi
Diffusive shock acceleration theory suggests that the ``universal'' energy spectrum of electrons with a power-law index p approximately equal to 2.3, commonly used to model GRB aft…
Optical observations of the bright long duration peculiar GRB 021004 afterglow
S. B. Pandey, D. K. Sahu, L. Resmi +9
The CCD magnitudes in Johnson and Cousins and photometric passbands are determined for the bright long duration GRB 021004 afterglow from 2002 October 4 to 16 startin…
General Relativistic Spectra from Accretion Disks around Rapidly Rotating Neutron Stars
Sudip Bhattacharyya, Dipankar Bhattacharya, Ranjeev Misra +1
We compute spectra from accretion disks around rapidly rotating neutron stars. The full effect of general relativity is considered for the structure calculation of the stars. We ta…
Optical and Radio observations of the bright GRB010222 afterglow: evidence for rapid synchrotron cooling?
R. Sagar, C. S. Stalin, D. Bhattacharya +8
We report photometric observations of the optical afterglow of GRB010222 in V,R and I passbands carried out at UPSO, Naini Tal between 22-27 Feb 2001. We determine CCD Johnson BV a…
