Origin of X-rays in the low state of the FSRQ 3C 273: Evidence of inverse Compton emission
Nibedita Kalita, Alok C. Gupta, Paul J. Wiita +2
We analyze the 2.5--10 keV X-ray spectra of the luminous quasar 3C 273 and simultaneous observations in UV wavelengths from XMM--Newton between 2000 and 2015. The lowest flux level…
Peak of spectral energy distribution play an important role in intra-day variability of Blazars?
Alok C. Gupta, Nibedita Kalita, Haritma Gaur +1
Blazars can be divided into two sub-classes namely high energy and low energy peaked blazars. In spectral energy distribution, the first synchrotron hump of the former class peaks…
Studies of Quasi Periodic Oscillations in the Black Hole Transient XTE J 1817-330
Jayashree Roy, P. C. Agrawal, B. Paul +1
We have used archival RXTE PCA data to investigate timing and spectral characteristics of the transient XTE J1817-330. The data pertains to 160 PCA pointed observations made during…
