Different Types of X-ray Variability Observed in Micro-Quasar GRS 1915+105 with the IXAE
S. Naik, P. C. Agrawal, B. Paul +3
The galactic micro-quasar source GRS 1915+105 has been observed with the Indian X-ray Astronomy Experiment (IXAE) several times over a period extending from 1996 to 2000. The sourc…
Broad band X-ray spectrum of Cygnus X-1
V. R. Chitnis, A. R. Rao, P. C. Agrawal
We present the hard X-ray (20-100 keV) observations of Cygnus X-1 obtained using a large area balloon-borne Xenon filled Multi-anode Proportional Counter (XMPC) telescope. The obse…
Observations of Cygnus X-1 during the two spectral states with the Indian X-ray Astronomy Experiment (IXAE)
A. R. Rao, P. C. Agrawal, B. Paul
We present the time variability characteristics of Cygnus X-1 in its two spectral states. The observations were carried out using the Pointed Proportional Counters (PPC) on-board t…
A double peaked pulse profile observed in GX 1+4
B. Paul, P. C. Agrawal, A. R. Rao +1
The hard X-ray pulsar GX 1+4 was observed several times in the last few years with a pair of balloon-borne Xenon filled Multi-cell Proportional Counters (XMPC). In a balloon flight…
Rapid X-ray variability of the superluminal source GRS1915+105
B. Paul, P. C. Agrawal, A. R. Rao
The superluminal X-ray transient source GRS 1915+105 was observed during July 20-29, 1996 with the Indian X-ray Astronomy Experiment (IXAE) on the Indian satellite IRS-P3 launched…
