  • Empirical Determination of Threshold Partial Wave Amplitudes for pp → ppω 
    Ramachandran, G; Balasubramanyam, J; Vidya, M. S; Venkataraya (World Scientific Publishing Company, 2006-08)
    Using the model-independent irreducible tensor approach to ω production in pp collisions, we show theoretically that it is advantageous to measure experimentally the polarization of ω, in addition to the proposed experimental ...

  • An empirical relation to estimate host galaxy stellar light from AGN spectra 
    Jalan, Priyanka; Rakshit, Suvendu; Woo, Jong-Jak; Kotilainen, Jari; Stalin, C. S (Oxford University Press on behalf of Royal Astronomical Society, 2023-05)
    Measurement of black hole mass for low-z (z≤ 0.8) Active Galactic Nuclei (AGNs) is difficult due to the strong contribution from host galaxy stellar light necessitating detailed spectral decomposition to estimate the AGN ...

    The Rotator Bulletin of the Rotary Club of Bangalore (The Rotator Bulletin of the Rotary Club of Bangalore, 1978-04-14)
  • Energetic Solar Particles 
    Biswas, S (Astronomical Society of India, 1975-12)
  • Energetics of a Kerr blackhole in electromagnetic fields: Role of the relative angular velocity of charged particles 
    Parthasarathy, S; Dhurandhar, S. V; Dadhich, N (Astronomical Society of India, 1985-06)
  • Energetics of solar coronal mass ejections 
    Subramanian, P; Vourlidas, Angelos (EDP Sciences, 2007-05)
    Aims.We investigate whether solar coronal mass ejections are driven mainly by coupling to the ambient solar wind or through the release of internal magnetic energy. Methods.We examine the energetics of 39 flux-rope like ...
  • Energy and angular momentum transfer in binary galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (NASA, 1990-11)
    The authors numerically studied tidal effects of a massive perturber on a satellite galaxy. The model consists of a spherical satellite galaxy and a point mass perturber and the encounter is non-penetrating. A wide range ...
  • Energy and Radiation Spectrum of Electrons in Ultra-relativistic Shocks of GRB Afterglows 
    Resmi, L; Bhattacharya, D (Astronomical Society of India, 2003)
    We consider particle acceleration near ultra relativistic shocks (shock p 1) and the distribution of accelerated particles in the shock downstream. We suggest that the electron energy spectrum will settle mp into an ...
  • The Energy Dependence of the Photoelectric Attenuation Coefficient of Substances 
    Chatterjee, S; Vyas, A; Ravanfar Haghighi, R; Kumar, P (Global Center for Advanced Research in Biomedical Physics and Biomedical Engineering, 2011)
    Introduction: The photoelectric attenuation coefficient of substances is known to depend upon the energy E of the photon and the effective atomic number of substances (Zeff) as (Zeff x/Ey). No definitive values about ...
  • Energy dependence of x-ray pulse profile of the crab pulsar 
    Mukerjee, K; Agrawal, P. C; Paul, B; Rao, A. R; Vahia, M. N; Yadav, J. S; Seetha, S; Kasturirangan, K (Astronomical Society of India, 1999)
    We obtained pulse profiles of Crab pulsar in 4 different X-ray energy bands between 2 and 30 keV. We found that all the profiles in these energy ranges show two peaks occurring at the same phase joined by a lower but non ...
  • Energy distribution of solar flare events 
    Sen, Samrat; Mangalam, A; Ramesh, R (Cambridge University Press, 2018-02)
    The coronal field typically reorganizes itself to attain a force-free field configuration. We have evaluated the power law index of the energy distribution f(E) = f0E−α by using a model of relaxation incorporating ...
  • Energy enigmas in the early universe and related problems in Newtonian cosmology 
    Sivaram, C (Springer, 1988-01)
    Some paradoxical situations regarding the balance between the different forms of energy present and the velocities of expansion in the early stages of the big bang are discussed. Solutions are suggested in the framework ...
  • Energy exchange during collision of a pair of disc-sphere galaxies 
    Namboodiri, P. M. S; Kochhar, R. K (Kluwer Academic Publishers, 1989-02)
    We have considered the collision of a pair of disc-sphere galaxies under the impulsive approximation to study the variation of the energy change of the disc due to the passage of a spherical galaxy. Various collision ...
  • Energy Loss due to Gravitational Radiation in Galaxy Mergers 
    Sivaram, C; Alladin, S. M (Astronomical Society of Indian, 1986-12)
  • Energy resolution of the TACTIC imaging element 
    Sathyabama, N; Dhar, V. K; Koul, M. K; Bhat, C. L (Astronomical Society of India, 2001)
    We explore here the possibility of using artificial neural network (ANN) for characterization of atmospheric Cerenkov events (progenitor type and energy) detected by the imaging gamma-ray telescope array, TACTIC.
  • Energy Sensitive Search for Pulsed Photons from Crab Pulsar using the TACTIC Imaging Element 
    Rannot, R. C; Yadav, K. K; Dhar, V. K; Tickoo, A. K; Bhatt, N; Bhattacharyya, S; Chandra, P; Goyal, H. C; Kaul, C. L; Kaul, R. K; Kothari, M; Kotwal, S; Koul, R; Sahayanathan, S; Sapru, M. L; Sharma, M; Venugopal, K; Bhat, C. L (Astronomical Society of India, 2003)
    The Imaging Element (IE) of the 4-element TACTIC array of atmospheric Cherenkov telescopes is in operation at Mt. Abu Rajasthan, in Western India. We have successfully detected a steady signal from the Crab Nebula at a ...
  • Energy transport in intense flux tubes on the sun. I - Equilibrium atmosphere 
    Hasan, S. S (The American Astronomical Society, 1988-09)
    Model calculations are performed to determine self-consistently the equilibrium atmosphere in an intense flux tube. The generalization of the Eddington approximation to three dimensions is used to develop a zeroth-order ...
  • Energy transport to the solar corona by magnetic kink waves 
    Choudhuri, A. R; Dikpati, M; Banerjee, D (American Astronomical Society, 1993-08-20)
    We show that the magnetic kink waves generated by the motions of photospheric footpoints of the coronal flux tubes can supply adequate energy for heating the quiet corona, provided there are occasional rapid motions of ...
