Effect of plasma composition on accretion on to black holes
Indranil Chattopadhyay
Matter makes a transition from non-relativistic to relativistic regime, as it falls onto a black hole. We employ a relativistic equation of state, abbreviated as RC, to study multi…
Black Hole Accretion: From Quasars to Nano-Quasars
S. K. Chakrabarti
In this review we shall comment on a few recent findings which strengthen the view that the black hole accretion has substantial amount of sub-Keplerian component. The manifestatio…
QPO Evolution in 2005 Outburst of the Galactic Nano Quasar GRO J1655-40
D. Debnath, A. Nandi, P. S. Pal +1
GRO J1655-40 showed significant X-ray activity in the last week of February, 2005 and remained active for the next 260 days. The rising and the decline phases of this particular ou…
Exploring a New Population of Compact Objects: X-ray and IR Observations of the Galactic Centre
Reba M. Bandyopadhyay, Andrew J. Gosling, Stephen E. Eikenberry +5
I describe the IR and X-ray observational campaign we have undertaken for the purpose of determining the nature of the faint discrete X-ray source population discovered by Chandra…
Results of Recent Multi-wavelength Campaign of SS433
S. Pal, Sandip K. Chakrabarti, K. Goswami +3
We conducted multi wavelength campaign on SS433 in Sept. 2002 using X-ray, B, Infra-Red and radio telescopes. We observed variabilities on a time-scale of few minutes in all the wa…
Can DNA bases be produced during molecular cloud collapse?
Sonali Chakrabarti, Sandip K. Chakrabarti
Using a reasonably large chemical reaction network consisting of 421 species, we show that along with normal chemical evolution of molecular cloud during collapse and star formatio…
