Description
High Altitude GAmma Ray (HAGAR) telescope array installed at Ladakh in
Himalayas has been operating since September, 2008. Since then several
galactic objects like Crab nebula, Geminga pulsar and X-ray binaries have
been observed. Also many extragalactic objects like active galactic nuclei
(Mkn 421, Mkn 501) have been observed with HAGAR. In particular, flux
from Mkn 421 observed in February, 2010 confirmed its flaring state and
its multi-waveband spectral energy distribution (SED) suggested a possible
reason for high state in flux activity was due to passing of shock in the
jet. Estimates of performance parameters from simulations will also be
presented. Finally, I'll discuss the present status of MACE (Major
Atmospheric Cherenkov Experiment), the second phase of HIGRO installation
which will have a 21m diameter imaging Cherenkov telescope.
