  • Probing the Evolution of the Gas Mass Fraction with the Sunyaev-Zeldovich Effect 
    Majumdar, S (American Astronomical Society, 2001-07)
    Study of the primary anisotropies of the cosmic microwave background (CMB) can be used to determine the cosmological parameters to a very high precision. The power spectrum of the secondary CMB anisotropies due to the ...
  • Relativistic ab initio spectroscopy study of forbidden lines of singly ionized zinc 
    Dixit, G; Sahoo, B. K; Chaudhuri, R. K; Majumdar, S (Institute of Physics, 2009-08-28)
    The ab initio calculation has been carried out to study the astrophysically important forbidden electromagnetic transition rates of singly ionized zinc (Zn II). Electron correlations are considered to all orders using ...
  • Sunyaev-Zel'dovich distortion from early galactic winds 
    Majumdar, S; Nath, B. B; Chiba, M (Royal Astronomical Society, 2001-07)
    We consider the distortion in the cosmic microwave background (CMB) resulting from galactic winds at high redshift. Winds outflowing from galaxies have been hypothesized to be possible sources of metals in the intergalactic ...
