Gravitational lensing constraint on the cosmic equation of state
Deepak Jain, Abha Dev, N. Panchapakesan +2
Recent redshift-distance measurements of Type Ia supernovae (SNe Ia) at cosmological distances suggest that two-third of the energy density of the universe is dominated by dark ene…
Constraints on the Cosmic Equation of State using Gravitational Lensing Statistics with evolving galaxies
Abha Dev, Deepak Jain, N. Panchapakesan +2
In this paper, observational constraints on the cosmic equation of state of dark energy () have been investigated using gravitational lensing statistics. A likelihood anal…
Constraints On Galaxy Evolution Through Gravitational Lensing Statistics
Deepak Jain, N. Panchapakesan, S. Mahajan +1
Explaining the formation and evolution of galaxies is one of the most challenging problems in observational cosmology. Many observations suggest that galaxies we see today could ha…
Gravitational Lensing Bound On The Average Redshift Of Gamma Ray Bursts In Models With Evolving Lenses
Deepak Jain, N. Panchapakesan, S. Mahajan +1
Identification of gravitationally lensed Gamma Ray Bursts (GRBs) in the BATSE 4B catalog can be used to constrain the average redshift of the GRBs. In this paper we invest…
Effect Of Galaxy Evolution On The Statistical Properties Of Gravitational Lenses
Deepak Jain, N. Panchapakesan, S. Mahajan +1
The paper has been withdrawn by the authors due to some error in the manuscript.
Constraint On The Cosmological Constant From Gravitational Lenses In An Evolutionary Model Of Galaxies
Deepak Jain, N. Panchapakesan, S. Mahajan +1
We study the effect of the cosmological constant on the statistical properties of gravitational lenses in flat cosmologies (Omega_{0}+lambda_{0} = 1). It is shown that some of the…
