  • Faraday rotation versus stimulated Raman scattering in intense sources 
    Gangadhara, R. T; Krishan, V (Astronomical Society of India, 1993)
    A coherent plasma process such as the stimulated Raman scattering plays significant role in bringing about the changes in polarization characteristics of radiation. It is found that some of the observed polarization ...
  • Modelling sunspot equilibrium through a solution of the time dependent MHD equations 
    Gangadhara, R. T; Hasan, S. S (Astronomical Society of India, 1996)
    We numerically simulate the dynamical relaxation to equilibrium of a sunspot. Treating the sunspot as a thick axisymmetric flux tube in cylindrical geometry, we solve the time dependent MHD equation to examine the evolution ...
  • Nonlinear Propagation of Intense Electromagnetic Waves in Quasar and Pulsar Plasmas 
    Gangadhara, R. T (Astronomical Society of India, 1997)
    We present the results of analytical as well as numerical investigations of radiation-plasma interaction instabilities in astrophysical plasmas. We consider the stimulated Raman and Compton scattering in the continuum ...
  • Radio Emission by Particles Accelerated in Pulsar Magnetosphere 
    Thomas, R. M. C; Gangadhara, R. T (Astronomical Society of India, 2003)
    We present a relativistic model of pulsar radio emission by plasma accelerated along the rotating magnetic field lines projected on to a 2D plane perpendicular to the rotation axis. We have derived the expression for the ...
  • Window-threshold technique for detecting pulse components 
    Gangadhara, R. T (Astronomical Society of India, 2000)
    We have analysed high-quality single pulse data of PSR B0329+54 at 606 MHz to study the structure of the emission beam. In order to unambiguously detect weak emission components in the integrated pulse profile, we have ...
