  • Detection of a branching-off feature from the Cygnus-Orion arm in the direction of Carina 
    Babu, G. S. D (Elsevier Science B.V., 1988)
    A program is presented for the study of faint young open clusters in the anticenter direction of the Galaxy with the aim of using these clusters as spiral arm tracers. Twelve open clusters are selected for observation. ...
  • Embedded clusters in giant extragalactic H II regions, 1: BVRH-alpha photometry 
    Mayya, Y. D (The American Astronomical Society, 1994-10)
    Photometry in BVR continuum bands and in the emission line of H-alpha+(N II) are presented for a sample of H II complexes in disk, spiral arm and nuclear regions of galaxies NGC 1365, 1566, 2366, 2903, 2997, 3351, 4303, ...
  • Mond, dark matter and the cosmological constant 
    Sivaram, C (Springer, 1994-09)
    A possible connection between MOND (Modification of Newtonian Dynamics) proposed as an alternative hypothesis to dark matter in galaxies and clusters and a residual cosmological constant term dominating cosmological dynamics ...
  • Non-zero rest mass neutrinos and the cosmological constant 
    Sivaram, C (Kluwer Academic Publisher, 1985-11)
    Recently it was pointed out that a non-zero cosmological constant can play a role in the formation of neutrino halos only in the case of neutrinos of very low rest mass (mν ≤ 0.1 eV). However, phase-space considerations ...

  • Nucleus of NGC 2903 
    Prabhu, T. P (D.Reidel Publishing Co.,, 1980-04)
    The nucleus of NGC 2903 is identified on near infrared photographs. The energy distribution of this nucleus in the visual region of the spectrum is estimated from available observations. The continuum compares well with ...
  • On structure formation in the universe 
    Satya Narayanan, A (Springer, 1994-12)
    The formation of structures in the universe is one of the most challenging problems of cosmology. In this paper, an attempt to explain the formation of galaxies through the generation of vortices (with dissipation) in an ...
  • Some aspects of MOND and its consequences for cosmology 
    Sivaram, C (Springer, 1994-05)
    Some consequences of MOND (Modification of Newtonian dynamics) proposed as an alternative hypothesis to dark matter for various astrophysical situations is discussed. The ubiquitous occurrence of the fundamental acceleration ...
