I am working on the modification of theory of gravitational lensing when the lens is in motion with the dark energy is taken into account. This results in non trivial modifications to lensing both in weak field and strong filed limits. I am particularly interested in the velocity dispersions of distant galaxies and how they can be indications of nature of their respective local enviorment.
My student and I have been calculating the gravitational lensing properties of charged blackholes.
In joint project, I am also working to understand the nature of the dark energy in the context of the standard model of particle physics.
I have also been working on the various distance estimates
in the universe dominated by dark energy.
Research Interests in Observational Astronomy
With astronomers at the European Observatory astronomers,
I have used
large telescopes in
Chile to observe the haloes of very distant galaxies too
see if there exists any young stars.
Our findings have been positive so far challenging the
modern theories of galaxy formation.
Research Interests in Mathematics
In a short, joint project, we are considering the
proof of an inequality for the orthant probabilities of a
multivariate t-distribution.
Research Interests in Archeoastronomy
I am deeply interested Archeoastronomy, especially
in ancient Egypt.
I believe that sighting of stars by the ancient
Egyptians may provide an exceedingly accurate unique
method of deducing when certain accurately aligned
structures were erected.
Research Interests in Astrobiology
A critical look at the modern astronomical observations
and at the nature life here on Earth, it is natural to
expect the fact that life must be commonplace throughout
the universe.
I am particularly interested in the possibility
of at least microbial life on Mars.
I am very keen on the latest discovery of Methane
in the atmosphere of Mars.
