Hydrodynamic Simulation of Two Component Advective Flows around Black Holes
Kinsuk Giri, Sandip K. Chakrabarti
We carry out a series of numerical simulations of viscous accretion flows having a reasonable spatial distribution of the viscosity parameter. We add the power-law cooling througho…
Study of the chemical evolution and spectral signatures of some interstellar precursor molecules of adenine, glycine alanine
Liton Majumdar, Ankan Das, Sandip K. Chakrabarti +1
We carry out a quantum chemical calculation to obtain the infrared and electronic absorption spectra of several complex molecules of the interstellar medium (ISM). These molecules…
Effects of Compton Cooling on Outflow in a Two Component Accretion Flow around a Black Hole: Results of a Coupled Monte Carlo-TVD Simulation
Sudip K. Garain, Himadri Ghosh, Sandip K. Chakrabarti
We wish to investigate the effects of cooling of the Compton cloud on the outflow formation rate in an accretion disk around a black hole. We carry out a time dependent numerical s…
Hydro-chemical study of the evolution of interstellar pre-biotic molecules during the collapse of molecular clouds
Liton Majumdar, Ankan Das, Sandip K. Chakrabarti +1
One of the stumbling blocks for studying the evolution of interstellar molecules is the lack of adequate knowledge of the rate co-efficients of various reactions which take place i…
Accretion flow dynamics during the evolution of timing and spectral properties of GX 339-4 during its 2010-11 outburst
Anuj Nandi, Dipak Debnath, Samir Mandal +1
The Galactic black-hole candidate GX 339-4 exhibited several outbursts at regular intervals of \sim 2-3 years in the Rossi X-ray Timing Explorer (RXTE) era. After remaining in an a…
A double component in GRB 090618: a proto-black hole and a genuinely long GRB
L. Izzo, R. Ruffini, A. V. Penacchioni +6
The joint X and gamma-ray observations of GRB 090618 by a large number of satellites offer an unprecedented possibility of testing crucial aspects of theoretical models. In particu…
