Saha ionization equation in early universe
Aritra Das, Ritesh Ghosh, S. Mallik
The Saha equation follows from thermal equilibrium of matter and radiation. We discuss this problem of equilibrium in the early universe, when matter consists mostly of electrons,…
A study of X-ray emission of galaxies hosting molecular outflows (MOX sample)
Sibasish Laha, Matteo Guainazzi, Enrico Piconcelli +5
We have carried out an extensive X-ray spectral analysis of a sample of galaxies exhibiting molecular outflows (MOX sample), to characterize the X-ray properties and investigate th…
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…
