  • Gangadhara, R. T; Thomas, R. M. C (Springer Netherlands, 2008)
    We have analyzed the profile of the millisecond pulsar PSR J0437-4715 at 1440 MHz by fitting the Gaussians to pulse components, and identified its 11 emission components. We propose that they form a emission beam with 5 ...
  • Kaul, R. K; Kaul, C. L; Bhat, C. L (Astronomical Society of India, 1999)
    The detectability of millisecond pulsars in VHE gamma-ray bracket (>5x10 to the power 11 eV), with the recently-commissioned TACTIC array, has been investigated on the basis of system energetics and the pulsar polar gap ...
  • Vishwanath, P. R; Acharya, B. S; Bhat, P. N; Chitnis, V. R (Tata Institute of Fundamental Research, 2005)
    A simple experimental apparatus was used to measure rate of cosmic ray events due to Atmospheric Cerenkov Radiation at two mountain altitude sites with the height difference of 3.5 km. The event rates at Hanle (altitude ...
  • Jaini, Akhil; Deshpande, Avinash A; Bitragunta, Sainath (Cambridge University Press, 2021-08)
    The radio sky at lower frequencies, particularly below 20 MHz, is expected to be a combination of increasingly bright non-thermal emission and significant absorption from intervening thermal plasma. The sky maps at these ...
  • de Sabbata, V; Sivaram, C (Springer, 1992-04)
    We show that introducing torsion in general relativity, that is, physically, considering the effect of the spin and linking the torsion to defects in spacetime topology, we can have a minimal unit of time. Also an uncertainty ...
  • Shevgaonkar, R. K (Indian Academy of Sciences, 1986-12)
    The minimum-relative-entropy method (MREM) is proposed as a solution to the missing short-baseline problem in radio synthesis observations. It is shown that a measure of distance between the prior model and the image in ...
  • Appleby, Stephen; Kochappan, Joby P; Pravabati, C; Park, Changbom (American Astronomical Society, 2023-01-10)
    The Minkowski tensors (MTs) can be used to probe anisotropic signals in a field, and are well suited for measuring the redshift-space distortion (RSD) signal in large-scale structure catalogs. We consider how the linear ...
  • Appleby, S; Pravabati, C; Park, C; Yogendran, K. P; Joby, P. K (IOP Publishing, 2018-08)
    We apply the Minkowski tensor statistics to three-dimensional Gaussian random fields. Minkowski tensors contain information regarding the orientation and shape of excursion sets that is not present in the scalar Minkowski ...
  • Appleby, S; Pravabati, C; Park, C; Hong, S. E; Kim, J; Vidhya, G (IOP Publishing, 2018-05-10)
    We apply the Minkowski tensor statistics to two-dimensional slices of the three-dimensional matter density field. The Minkowski tensors are a set of functions that are sensitive to directionally dependent signals in the ...
  • Bhattacharyya, J. C (Centre of Advanced Study in Astronomy Osmania University, 1984)
    Circumstances of the discovery of the first asteroid and the characteristics of various orbits followed by them have been discussed. Their shapes, compositions and evolutionary histories so far known have also been described. ...

    In recent years, certain luminous extragalactic optical transients have been observed to last only a few days1. Their short observed duration implies a different powering mechanism from the most common luminous extragalactic ...
  • Sarkar, Kartick C; Mondal, Santanu; Sharma, Prateek; Piran, Tsvi (American Astronomical Society, 2023-07-01)
    One of the leading explanations for the origin of Fermi Bubbles is past jet activity in the Galactic center supermassive black hole Sgr A*. The claimed jets are often assumed to be perpendicular to the Galactic plane. ...

    Million Book Project (MBP) (2001-2007) aims to digitize at least one million books and offer them to everyone around the world, free-ta-read on the Internet. This is a co11aborative effort by fifteen partners from ...
