  • HER X-1 observed in a low state 
    Paul, B; Agrawal, P. C; Rao, A. R; Manchanda, R. K (Astronomical Society of India, 1996)
    The X-ray pulsar Her X-1 was observed on 14th December, 1992 with two balloon borne Xenon filled multicell proportional counters (XMPC) from Hyderabad, India. The source intensity was found to be very low in the 20-100 KeV ...
  • 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 ...
  • Observation of X-ray binary Cygnus X-3 by Indian X-ray Astronomy Experiment 
    Singh, N. S; Singh, K. Y; Naik, S; Paul, B; Agrawal, P. C (Astronomical Society of India, 2001)
    The X-ray binary Cygnus X-3 was observed with the Indian X-ray Astronomy Experiment (IXAE) on Board the Indian Remote Sensing Satellite IRS-P3 during July 3-13, 1999 and October 11-24, 1999 with total useful exposure time ...
  • Orbital Evolution of the Binary X-ray Pulsar Her X-1 
    Bhatt, N; Paul, B; Koul, C. L (Astronomical Society of India, 2003)
    We report the discovery of a break in the orbital period evolution of Her X-1, coincident with a recent anomalous low state.
  • Pulsating Soft Components in the Accreting X-ray Pulsars LMC X-4 and SMC X-1 
    Naik, S; Paul, B (Astronomical Society of India, 2003)
    We report here spectral study of two accreting binary X-ray pulsars LMC X-4 and SMC X1 made with the Beppo-SAX observatory. The energy spectrum of both the pulsars in 0.1-10.0 keV band can be described by a model consisting ...
  • Study of two pulsars with the Indian X-ray Astronomy Experiment 
    Mukerjee, K; Agrawal, P. C; Paul, B; Rao, A. R; Yadav, J. S; Seetha, S; Kasturirangan, K (Astronomical Society of India, 2000)
    The X-ray pulsars Cep X-4 and 4U 1907+09 were observed with the Indian X-ray Astronomy Experiment (IXAE). Observations of Cep-X4 were made during the declining phase of its latest 30 days outburst in 1997, July-August. The ...
  • X-ray bursts from GRS 1915+105 observed with IXAE 
    Yadav, J. S; Agrawal, P. C; Paul, B; Rao, A. R; Vahia, M. N; Seetha, S; Kasturirangan, K (Astronomical Society of India, 1999)
    The light curves of the galactic superluminal X-ray transient source GRS1915+105 observed with the pointed proportional counters (PPC) of Indian X-ray Astronomy Experiment (IXAE)on board IRS-P3 have revealed the presence ...
  • The X-ray observation of newly discovered transient XTE J1748-288 by the Indian X-ray Astronomy Experiment 
    Naik, S; Agrawal, P. C; Paul, B; Rao, A. R; Seetha, S; Kasturirangan, K (Astronomical Society of India, 2000)
    The observations of X-ray transient XTE J1748-288 were made in the energy band 2 - 18 keV with the Indian X-ray astronomy experiment (IXAE) during 1998, June 14-25 with total useful exposure of 27,100 second for 1 sec ...
  • X-ray Spectroscopy of the HMXB Pulsar GX 301-2 with Chandra 
    Mukherjee, U; Paul, B (Astronomical Society of India, 2003)
    We present analysis of X-ray spectra of the accreting pulsar GX 301-2, from two observations with the Chandra X-ray observatory made during different phases of its orbital period. Analysis of the zeroth order ACIS spectra ...
