Spectral States of OJ 287 blazar from Multi-wavelength Observations with
K. P. Singh, P. Kushwaha, A. Sinha +3
We present {\it AstroSat} soft X-ray, near-UV (NUV), and far-UV (FUV) observations of a blazar, OJ~287, carried out in 2017, 2018, and 2020. The simultaneous observations with NuST…
Spectro-Timing Analysis of a highly variable narrow-line Seyfert 1 galaxy NGC 4748 with AstroSat and XMM-Newton
Main Pal, Neeraj Kumari, Pankaj Kushwaha +8
We present a detailed timing and spectral study of an extremely variable narrow-line Seyfert~1 galaxy NGC 4748 using observations in the year 2017 and 2014 performed with AstroSat…
Blazar OJ 287 After First VHE Activity: Tracking the Re-emergence of the HBL like Component in 2020
Pankaj Kushwaha, Main Pal, Nibedita Kalita +5
We report the re-emergence of a new broadband emission through a detailed and systematic study of the multi-wavelength spectral and temporal behavior of OJ 287 after its first-ever…
Short-term X-ray Variability during Different Activity Phases of Blazars S5 0716+714 and PKS 2155-304
Pankaj Kushwaha, Main Pal
We explored the statistical properties of short-term X-ray variability using long-exposure {\it XMM-Newton} data during high X-ray variability phases of blazars S5 0716+714 and PKS…
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…
