  • A Statistical Study of Low-Frequency Solar Radio Type III Bursts 
    Mahender, A; Sasikumar Raja, K; Ramesh, R; Panditi, V; Monstein, C; Yellaiah, G (Springer, 2020-11)
    We have studied low-frequency (45 – 410 MHz) type III solar radio bursts observed using the e-Compound Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory (e-CALLISTO) spectrometer ...
  • Strength of the Solar Coronal Magnetic Field A Comparison of Independent Estimates Using Contemporaneous Radio and White-Light Observations 
    Anshu Kumari; Ramesh, R; Kathiravan, C; Wang, T. J (Springer, 2017-11)
    Abstract We estimated the coronal magnetic field strength (B) during the 23 July 2016 coronal mass ejection (CME) event using i) the flux rope structure of the CME in the whitelight coronagraph images and ii) the ...
  • Turbulent Density Fluctuations and Proton Heating Rate in the Solar Wind from 9-20 R 
    Sasikumar Raja, K; Subramanian, P; Ramesh, R; Vourlidas, Angelos; Ingale, M (IOP Publishing, 2017-12)
    We obtain scatter-broadened images of the Crab Nebula at 80 MHz as it transits through the inner solar wind in 2017 and 2016 June. These images are anisotropic, with the major axis oriented perpendicular to the radially ...
  • Turbulent proton heating rate in the solar wind from 5–45 R⊙ 
    Sasikumar Raja, K; Subramanian, P; Ingale, M; Ramesh, R; Maksimovic, Milan (IOP Publishing, 2021-06-20)
    Various remote sensing observations have been used so far to probe the turbulent properties of the solar wind. Using the recently reported density modulation indices that are derived using angular broadening observations ...
  • Type I radio bursts and the minimum between sunspot cycles 22 & 23 
    Ramesh, R; Shanmugha Sundaram, G. A (European Southern Observatory, 2000-12)
    Spectral observations of Type I radio bursts published in the Solar Geophysical Data are used to show that the minimum between solar cycles 22 & 23 occurred during October 1996.
  • A world-wide net of solar radio Spectrometers: e-CALLISTO 
    Benz, A. O; Monstein, C; Meyer, H; Manoharan, P. K; Ramesh, R; Altyntsev, A; Lara, A; Paez, J; Cho, K.S (Springer, 2009-04)
    Radio spectrometers of the CALLISTO type to observe solar flares have been distributed to nine locations around the globe. The instruments observe automatically, their data is collected every day via internet and stored ...
