  • Further Constraints on Electron Acceleration in Solar Noise Storms 
    Subramanian, P; Becker, P. A (Springer, 2006-08)
    We reexamine the energetics of nonthermal-electron acceleration in solar noise storms. A new result is obtained for the minimum nonthermal-electron number density required to produce a Langmuir-wave population of sufficient ...
  • Hybrid viscosity and magnetoviscous instability in hot, collisionless accretion disks 
    Subramanian, P; Becker, P. A; Kafatos, M. (Springer Netherlands, 2008)
    We aim to illustrate the role of hot protons in enhancing the magnetorotational instability (MRI) via the “hybrid” viscosity, which is due to the redirection of protons interacting with static magnetic field perturbations, ...
  • TeV blazar variability: the firehose instability? 
    Subramanian, P; Shukla, A; Becker, P. A (Wiley-Blackwell, 2012-06)
    Recently observed minute-time-scale variability of blazar emission at TeV energies has imposed severe constraints on jet models and TeV emission mechanisms. We focus on a robust jet instability to explain this variability. ...
