An X-ray view of central engines of low luminosity quasars (LLQSO) in the local Universe
Sibasish Laha, Ritesh Ghosh, Matteo Guainazzi +1
We have carried out a systematic X-ray spectral analysis of a sample of low luminosity quasars (LLQSO) to investigate the nature of the central engines of these sources. The optica…
Broadband spectral study of the jet-disc emission in the radio-loud narrow-line Seyfert 1 galaxy 1H 0323+342
Ritesh Ghosh, Gulab C. Dewangan, Labani Mallick +1
We present a broadband spectral study of the radio-loud narrow-line Seyfert 1 galaxy 1H~0323+342 based on multi-epoch observations performed with NuSTAR on 2014 March 15, and two s…
Accretion disk/corona emission from a radio-loud narrow line Seyfert 1 galaxy PKS 0558-504
R. Ghosh, G. C. Dewangan, B. Raychaudhuri
Approximately 10-20% of Active Galactic Nuclei are known to eject powerful jets from the innermost regions. There is very little observational evidence if the jets are powered by s…
