A fast powerful X-ray transient from possible tidal disruption of a white dwarf
Dongyue Li, Wenda Zhang, Jun Yang +97
Stars captured by black holes (BHs) can be torn apart by strong tidal forces, producing electromagnetic flares. To date, more than 100 tidal disruption events (TDEs) have been obse…
Multi-wavelength analysis of FSRQ B2 1348+30B: Constraints on the jet power
Sajad Ahanger, Sunder Sahayanathan, Sitha K. Jagan +2
We present 14.5-year multi-wavelength analysis of flat-spectrum radio quasar B2 1348+30B using Swift-UVOT, Swift-XRT, and Fermi-LAT observations. In the gamma-ray band, the 3 day b…
Do radiative losses determine the characteristic emission of the blazar Mkn 421?
C. Baheeja, S. Sahayanathan, Frank M. Rieger +2
The radiative loss interpretation for the broken power-law spectra of blazars is often questioned since the difference between the indices does not support this inference. Using th…
Convex X-ray Spectra of PKS 2155-304 and Constraints on the Minimum Electron Energy
Sitha K. Jagan, S. Sahayanathan, Frank M. Rieger +1
The convex (concave upward) high-energy X-ray spectra of the blazar PKS\,2155-304, observed by \emph{XMM-Newton}, is interpreted as the signature of sub-dominant inverse Compton em…
Establishing the Spectral Turnover of Blazar PKS 2155-304 as an Outcome of Radiative Losses
Sitha K. Jagan, S. Sahayanathan, R. Misra +2
The broad band optical/UV and X-ray spectra of blazars have been often modeled as synchrotron component arising from a broken power-law distribution of electrons. A broken power-la…
