Evolution of the temporal and the spectral properties in 2010 and 2011 outbursts of H 1743-322
Dipak Debnath, Sandip K. Chakrabarti, Anuj Nandi
The Galactic black hole candidate H~1743-322 exhibited two X-ray outbursts in rapid succession: one in August 2010 and the other in April 2011. We analyze archival data of this obj…
A comparative study of the timing and the spectral properties during two recent outbursts (2010 & 2011) of H 1743-322
Dipak Debnath, Sandip. K. Chakrabarti, Anuj Nandi
The Galactic black hole candidate (BHC) H~1743-322 recently exhibited two outbursts in X-rays in August 2010 & April 2011. The nature (outburst profile, evolution of quasi-periodic…
Is the `disappearance' of low-frequency QPOs in the power spectra a general phenomenon for Disk-Jet symbiosis?
A. Nandi, Radhika. D, S. Seetha
One of the best possible ways to look for disk-Jet symbiosis in galactic Black Holes is to study the correlation between X-ray and radio emissions. Beyond this study, is there any…
Nature of GRBs observed by RT-2 on-board CORONAS-PHOTON satellite
D. Debnath, A. Nandi, S. K. Chakrabarti +2
The RT-2 Experiment, a low energy gamma-ray telescope, onboard CORONAS-PHOTON satellite is designed to study the temporal, spectral and spatial properties of the hard X-ray solar f…
`Spectro-temporal' characteristics and disk-jet connection of the outbursting black hole source XTE J1859+226
D. Radhika, A Nandi
We re-investigated the `spectro-temporal' behaviour of the source XTE J1859+226 in X-rays during its outburst phase in 1999, by analysing the RXTE PCA/HEXTE data in 2 - 150 keV spe…
Comptonization efficiencies of the variability classes of GRS 1915+105
Partha Sarathi Pal, Sandip K. Chakrabarti, Anuj Nandi
The Galactic microquasar GRS 1915+105 exhibits at least seventeen types of variability classes. Intra and inter class transitions are reported to be observed within seconds to hour…
