AstroSat view of MAXI J1535-571: broadband spectro-temporal features
Sreehari H., Ravishankar B. T., Nirmal Iyer +4
We present the results of Target of Opportunity (ToO) observations made with AstroSat of the newly discovered black hole binary MAXI J1535-571. We detect prominent C-type Quasi-per…
Study of the long-term evolution of the accretion dynamics of GX 339-4
U. Aneesha, S. Mandal, H. Sreehari
We study the dynamical behaviour of the galactic black hole source GX 339-4 during 2002-2011 outbursts using RXTE, Swift(XRT), XMM-Newton(PN) archival data. We present the spectral…
PUNCH: Positive UNlabelled Classification based information retrieval in Hyperspectral images
Anirban Santara, Jayeeta Datta, Sourav Sarkar +3
Hyperspectral images of land-cover captured by airborne or satellite-mounted sensors provide a rich source of information about the chemical composition of the materials present in…
Shocks in relativistic viscous accretion flows around Kerr black holes
I. Dihingia, Santabrata Das, Debaprasad Maity +1
We study the relativistic viscous accretion flows around the Kerr black holes. We present the governing equations that describe the steady state flow motion in full general relativ…
A Possible Model for the Long-Term Flares of Sgr A*
Toru Okuda, Chandra B. Singh, Santabrata Das +3
We examine the effects of magnetic field on low angular momentum flows with standing shock around black holes in two dimensions. The magnetic field brings change in behavior and lo…
Accretion-ejection in rotating black holes: a model for `outliers' track of radio-X-ray correlation in X-ray binaries
Ramiz Aktar, Anuj Nandi, Santabrata Das
We study the global accretion-ejection solutions around a rotating black hole considering three widely accepted pseudo-Kerr potentials that satisfactorily mimic the space-time geom…
