  • Neutrino effective charge and cerenkov radiation 
    D'Olivo, J. C; Nieves, J. F; Palash, B. P (Elsevier B.V., 1996-05)
    We consider the Čerenkov radiation emitted by neutrinos due to their effective electromagnetic interactions as they pass through a polarisable medium. The effect exists even for massless, chiral neutrinos, and no physics ...
  • Neutrino emission from supernovae in the presence of magnetic fields 
    Sivaram, C (Kluwer Academic Publishers, 1989)
    Neutrino burst observations from SN1987A indicate that the density and the temperature of the source and the propagation of the neutrinos in the medium are markedly different from those of solar and terrestrial conditions. ...
  • Neutrino induced nucleosynthesis 
    Ramadurai, S; Schramm, D. N (Astronomical Society of India, 1993)
    The detection of neutrinos from SN1987a has revived the interest in neutrino induced nucleosynthesis. In this work various results on the neutrino produced abundances of several isotopes are summarized and compared with ...
  • The neutrino magnetic moment in the early universe 
    de Sabbata, V; Sivaram, C (Italian Physical Society, 1990-05)
    The authors consider a spin-torsion coupling for neutrinos in the early universe and show that a neutrino magnetic moment can be present also for zeromass neutrinos. They make an estimate of this induced magnetic moment ...
  • Neutrino magnetic moment induced by torsion and consequences for supernova neutrinos 
    de Sabbata, V; Sivaram, C (International Cosmic Ray, 1990)
    If neutrinos couple to torsion in the frame work of the Einstein-Cartan theory, with a strength about that of the weak interaction, then the spin-torsion interaction can induce an effective neutrino magnetic moment. We ...
  • Neutrino mixing in gradational fields: Constraints on CP-Violating gravitational interactions 
    Sivaram, C (World Scientific, 1995)
  • Neutrinos from SN 1987A 
    Sivaram, C (Indian Institute of Astrophysics, 1988)
  • Neutrinos galactic dark matter and flat rotation curves 
    Sivaram, C (Copernicus Foundation for Polish Astronomy, 1987)
    Degenerate or partially degenerate density distributions of neutrinos do not give rise to flat rotation curves. If the galactic dark matter chiefly consists of neutrinos they would have to be isothermal. Such a halo of ...
  • The Neutron in Astrophysics 
    Sivaram, C (Astronomical Society of India, 1983-06)
  • Neutron interferometry in gravitational field with torsion 
    de Sabbata, Venzo; Pronin, P. I; Sivaram, C (Springer, 1991-12)
    We consider the possibility of finding experimental evidence of the fifth force with the measurement of a phase shift of neutron beams via an interferometric apparatus and also a possible rotation of the polarization plane ...
  • Neutron oscillation and the primordial magnetic field 
    Sivaram, C; Krishan, V (Gordon and Breach Science Publishers, 1983)
    The phenomenon of neutron-antineutron oscillations, recently proposed as a novel consequence of grand unified theories, permits limits to be placed on any primordial field present during the nucleosynthetic stage of the ...
  • Neutron oscillation as a source of excess sub-GeV antiprotons in galactic cosmic rays 
    Sivaram, C; Krishan, V (Nature Publishing Group, 1982-09)
    The recent detection1,2 of an antiproton/proton (/p) ratio at energies much less than 1 GeV is several orders of magnitude above that predicted for production from primary cosmic ray collisions. It is well recognized that ...
  • Neutron star physics in the square kilometre array era: an Indian perspective 
    Konar, S; Bagchi, Manjari; Bandyopadhyay, Debades; Banik, Sarmistha; Bhattacharya, D; Bhattacharyya, S; Gangadhara, R. T; Gopakumar, A; Gupta, Y; Joshi, B. C; Maan, Yogesh; Maitra, Chandreyee; Mukherjee, D; Pai, Archana; Paul, B; Ray, A; Sutaria, F. K (Indian Academy of Sciences, 2016-12)
    It is an exceptionally opportune time for astrophysics when a number of next-generation mega-instruments are poised to observe the Universe across the entire electromagnetic spectrum with unprecedented data quality. The ...
  • Neutron stars : Seen my way 
    Kundt, W (Astronomical Society of India, 2001)
    An unconventional survey is presented of the observable properties of neutron stars and of all astrophysical phenomena possibly related to them, such as their pulsing, clock irregularities, bursting, flickering, and ...
  • Neutrons and Gamma Rays from the Sun 
    Lavakare, J. V (Astronomical Society of India, 1977-09)
  • Neutrons stars as non-accelerator hadron physics laboratory 
    Datta, B (World Scientific, 1995)
    Neutron stars are extremely compact stellar objects, with density that of atomic nucleus and higher. The composition of neutron stars is believed to be mostly neutrons, with admixtures of protons, electrons and perhaps ...
  • New acquisition with new partners: are we ready yet? 
    Birdie, C (IATUL (International Association of Scientific and Technological Universities Libraries), 2002)
    The quantity of information purchased by libraries has been declining in recent years due to the price escalation of scholarly publications. Libraries are exploring new ways to provide more information with less budget. ...
  • New approach for inclusion of the effect of gravity in magnetohydrostatic equilibrium in solar coronal arcades 
    Prasad, L; Chandra, S (Astronomical Society of India, 1992)
    The study presents a novel approach for the inclusion of the effect of gravity in the magnetohydrostatic equilibrium in coronal arcades, in which the magnetic lines of force are unaffected whereas the pressure isobars are ...
  • A new approach to stellar image correction for atmospherically degraded images 
    Chinnappan, V (Indian Institute of Astrophysics, 2006-08)
    Atmospheric turbulence is the main cause of image degradation and poor resolution at the focal plane of a perfectly made optical telescope. It is necessary to make corrective measures to improve the optical wave-front, ...
