Distributed Data Acquisition System for Pachmarhi Array of Cerenkov Telescopes
P. N. Bhat, B. S. Acharya, V. R. Chitnis +18
Pachmarhi Array of \v Cerenkov Telescopes (PACT) consists of a 55 array of \v Cerenkov telescopes deployed over an area of 100 80 , in the form of a rectang…
Pachmarhi Array of Čerenkov Telescopes and its Sensitivity
V. R. Chitnis, B. S. Acharya, P. N. Bhat +9
Pachmarhi Array of Čerenkov Telescopes (PACT) has been designed to search for celestial TeV rays using the wavefront sampling technique. PACT, located at Pachmarhi, (latitude 2…
A Possible High Altitude High Energy Gamma Ray Observatory in India
R. Cowsik, P. N. Bhat, V. R. Chitnis +2
Recently an Indian Astronomical Observatory has been set up at Hanle (32 46 46 N, 78 57 51 E, 4515m amsl) situat…
Gamma-Hadron Separation using Čerenkov Photon Density Fluctuations
P. N. Bhat, V. R. Chitnis
In atmospheric Čerenkov technique rays are detected against abundant background produced by hadronic showers. In order to improve signal to noise ratio of the experiment, it is…
Estimation of Shower Parameters in Wavefront Sampling Technique
V. R. Chitnis, P. N. Bhat
Wavefront sampling experiments record arrival times of Čerenkov photons with high precision at various locations in Čerenkov pool using a distributed array of telescopes. It was sh…
Very High Energy Gamma Ray Emission from Crab and Geminga Pulsars
P. R. Vishwanath, B. S. Acharya, P. N. Bhat +4
The main inference from the experiments of the '80s that the time-averaged energy spectra of pulsars had to steepen in the GeV-TeV energy region has been reinforced in the '90s fro…
