Strong Soft X-ray Excess in 2015 XMM-Newton Observation of BL--Lac OJ~287
Main Pal, Pankaj Kushwaha, Gulab C. Dewangan +1
We report a strong soft X-ray excess in the BL--Lacartae -ray blazar OJ~287 during the long exposure in May 2015, amongst two of the latest \xmm~{} observations performed in May…
UV to X-ray Comptonization delay in Mrk 493
Oluwashina Adegoke, Gulab C. Dewangan, Pramod Pawar +1
The broadband X-ray emission from type 1 active galactic nuclei, dominated by a powerlaw continuum, is thought to arise from repeated inverse Compton scattering of seed optical/UV…
Complex UV/X-ray variability of 1H~0707-495
P. K. Pawar, G. C. Dewangan, I. E. Papadakis +3
We study the relationship between the UV and X-ray variability of the narrow-line Seyfert 1 galaxy 1H~0707-495. Using a year long {\it Swift} monitoring and four long {\it XMM-Newt…
On the reality of broad iron L lines from the narrow line Seyfert 1 galaxies 1H0707-495 and IRAS 13224-3809
Pramod Pawar, Gulab Dewangan, Madhav Patil +2
We performed time resolved spectroscopy of 1H0707-495 and IRAS 13224-3809 using long XMM-Newton observations. These are strongly variable narrow line Seyfert 1 galaxies and show br…
