  • Bar rejuvenation in S0 galaxies? 
    Barway, Sudhanshu; Saha, Kanak (Oxford University Press on behalf of the Royal Astronomical Society, 2020-07)
    Based on the colour measurements from a multiband, multicomponent 2D decompositions of S0 and spiral galaxies using SDSS images, we found that bars are bluer in S0 galaxies compared to the spiral galaxies. Most of the S0s ...
  • Baryogenesis via leptogenesis in presence of cosmic strings 
    Sahu, N; Bhattacharjee, P; Yajnik, U. A (Elsevier, 2006-09)
    We study the effect on leptogenesis due to B L cosmic strings of a U1 extension of the Standard Model. The disappearance of closed loops of B L cosmic strings can produce heavy right handed neutrinos, N's, whose CP-asymmetric ...
