  • Cosmological QCD phase transition and dark matter 
    Bhattacharyya, A; Alam, J; Sarkar, S; Roy, P; Sinha, B; Raha, S; Bhattacharjee, P (Elsevier, 1999-12)
    The authors calculate the size distribution of quark nuggets, which could be formed due to first order QCD phase transition in the early universe. They find that there are a large number of stable quark nuggets which could ...
  • How Thick are the Saturn's Rings? 
    Chakrabarti, S. K; Bhattacharyya, A (Astronomical Society of India, 2002-09)
    It has been long thought that the rings of saturn are probably not thicker than a few hundreds of meters. By actually following the motion of particles inside the decaying bending waves of the Saturn's rings and matching the ...
  • Relics of the cosmological QCD phase transition 
    Bhattacharyya, A; Alam, J. E; Sarkar, S; Roy, P; Sinha, B; Raha, S; Bhattacharjee, P (The American Physical Society, 2000-04)
    The abundance and size distribution of quark nuggets ~QN’s!, formed a few microseconds after the big bang due to a first-order QCD phase transition in the early universe, has been estimated. It appears that stable QN’s could ...
  • SS 433: results of a recent multiwavelength campaign 
    Chakrabarti, S. K; Anandarao, B. G; Pal, S; Mondal, S; Nandi, A; Bhattacharyya, A; Mandal, S; Sagar, R; Pandey, J. C; Pati, A. K; Saha, S. K (Royal Astronomical Society, 2005-09)
    We conducted a multiwavelength campaign in 2002 September-October, to observe SS 433. We used the Giant Meter Radio Telescope for radio observations, the Physical Research Laboratory Infrared Telescope at Mt Abu for infrared ...
