  • Faraday rotation signatures of fluctuation dynamos in young galaxies 
    Sur, Sharanya; Pallavi Bhat; Subramanian, K (Oxford University Press on behalf of the Royal Astronomical Society, 2018-03)
    Observations of Faraday rotation through high-redshift galaxies have revealed that they host coherent magnetic fields that are of comparable strengths to those observed in nearby galaxies. These fields could be generated ...
  • Galaxy formation 
    Padmanabhan, T; Subramanian, K (Astronomical Society of India, 1992)
    An attempt is made to develop a consistent theory describing galaxy formation. First, a discussion of the smooth universe is presented. The linear theory of perturbations is introduced, and its applications are described. ...
  • Magnetic helicity in galactic dynamos 
    Subramanian, K (Astronomical Society of India, 2002-09)
    Magnetic fields correlated on kiloparsec scales are seen in spiral galaxies. Their origin ~ould be due to amplification of a small seed field by a turbulent galactic dynamo. We review the current status of the galactic dynamo, ...
  • Probing magnetic fields with square kilometre array and its precursors 
    Roy, S; Sur, Sharanya; Subramanian, K; Mangalam, A; Seshadri, T. R; Chand, H (Indian Academy of Sciences, 2016-12)
    Origin of magnetic fields, its structure and effects on dynamical processes in stars to galaxies are not well understood. Lack of a direct probe has remained a problem for its study. The first phase of Square Kilometre ...
