Spectral connection between far UV and soft X-ray emission from active galactic nuclei using AstroSat
Shrabani Kumar, G. C. Dewangan, K. P. Singh +5
We present the UV/X-ray joint spectral analyses of four Seyfert~1 galaxies (PG 0804+761, NGC 7469, SWIFT J1921.1-5842, and SWIFT J1835.0+3240) using the data acquired with the Ultr…

Multi-epoch UV X-ray spectral study of NGC 4151 with AstroSat
Shrabani Kumar, G. C. Dewangan, P. Gandhi +8
We present a multi-wavelength spectral study of NGC 4151 based on five epochs of simultaneous AstroSat observations in the near ultra-violet (NUV) to hard X-ray band ($\sim 0.005-8…
