NGC4438 and its environment at radio wavelengths
Ananda Hota, D. J. Saikia, Judith A. Irwin
We present multi-frequency, radio-continuum and HI observations of NGC4438, the highly-disturbed, active galaxy in the Virgo cluster, with the VLA and the GMRT. High-resolution obs…
Radio bubbles in the composite AGN-starburst galaxy NGC6764
Ananda Hota, D. J. Saikia
We present multi-frequency radio continuum as well as HI observations of the composite galaxy NGC6764, which has a young, circumnuclear starburst and also harbours an active galact…
Infinite-range Ising ferromagnet in a time-dependent transverse field: quench and ac dynamics near the quantum critical point
Arnab Das, K. Sengupta, Diptiman Sen +1
We study an infinite range ferromagnetic Ising model in the presence of a transverse magnetic field which exhibits a quantum paramagnetic-ferromagnetic phase transition at a critic…
Non-equilibrium Green's function formalism and the problem of bound states
Abhishek Dhar, Diptiman Sen
The non-equilibrium Green's function formalism for infinitely extended reservoirs coupled to a finite system can be derived by solving the equations of motion for a tight-binding H…
Multi-band structure of the quantum bound states for a generalized nonlinear Schrodinger model
B. Basu-Mallick, Tanaya Bhattacharyya, Diptiman Sen
By using the method of coordinate Bethe ansatz, we study N-body bound states of a generalized nonlinear Schrodinger model having two real coupling constants c and η. It is found th…
A radio study of the superwind galaxy NGC1482
Ananda Hota, D. J. Saikia
We present multifrequency radio continuum as well as HI observations of the superwind galaxy NGC1482, with both the GMRT and the VLA. This galaxy has a remarkable hourglass-shaped…
