  • Analysis of the structural complexity of Crab Nebula observed at radio frequency using a multifractal approach 
    Chanu, Athokpam Langlen; Pravabati, C; Rahman, Fazlu; Singh, R K Brojen; Kharb, Preeti (IOP Publishing Ltd, 2024-03)
    The Crab Nebula is an astrophysical system that exhibits complex morphological patterns at different observing frequencies. We carry out a systematic investigation of the structural complexity of the nebula using publicly ...
  • Electromagnetic radiation in a helical magnetic field 
    Krishan, V (1984)
    Electromagnetic radiation spectrum is studied in a helical magnetic field since such magnetic field configurations may be present in cosmic objects. It is shown that, by a proper choice of the spatial period of the magnetic ...
  • Gamma-ray source observations with the HAGAR telescope system at Hanle in the Himalayas 
    Britto, R. J; Acharya, B. S; Chitnis, V. R; Cowsik, R; Dorji, N; Duhan, S. K; Gothe, K. S; Kamath, P. U; Mahesh, P. K; Nagesh, B. K; Naidu, A; Parmar, N. K; Prabhu, T. P; Rao, S. K; Saha, L; Saleem, F; Saxena, A. K; Sharma, S. K; Shukla, A; Singh, B. B; Srinivasan, R; Srinivasulu, G; Sudersanan, P. V; Tsewang, D; Upadhya, S. S; Vishwanath, P. R (Societe Francaise d’Astronomie et dAstrophysique, 2009-11)
    We have observed Crab nebula using the recently commissioned wavefront sampling high alti- tude (4270 m) array, HAGAR, at Hanle in the Ladakh region of the Himalayas. Regular source observations have begun with the ...
  • Preliminary results on the flux of TeV g-rays from crab system obtained with the PACT at Pachmarhi 
    Sripathi Acharya, B; Bhat, P. N; Chitnis, V. R; Majumdar, P; Rahman, M. A; Singh, B. B; Vishwanath, P. R (International Union of Pure and Applied Physics, 2003-07)
    We have observed the Crab system (Nebula and Pulsar) and the corresponding background regions during many clear nights in the years 1999-2002 ˇ using the atmospheric Cerenkov array at Pachmarhi, PACT. Preliminary results ...
  • VHE gamma-ray observation of Crab Nebula with HAGAR telescope array 
    Singh, B. B; Britto, R. J; Chitnis, V. R; Shukla, A; Saha, L; Sinha, A; Acharya, B. S; Vishwanath, P. R; Anupama, G. C; Bhattacharjee, P; Gothe, K .S; Nagesh, B. K; Prabhu, T. P; Rao, S. K; Srinivasan, R; Upadhya, S. S (Springer, 2019-12)
    HAGAR is a system of seven Non-imaging Atmospheric Cherenkov Telescopes located at Hanle in the Ladakh region of the Indian Himalay as at an altitude of 4270 meters amsl . Since 2008, we have observed the Crab Nebula to ...
