Prospects for Observations of Transient UV Events with the TAUVEX UV Observatory
Margarita Safonova, C. Sivaram, Jayant Murthy
Transient events have posed special problems in astronomy because of the intrinsic difficulty of their detection, and a new class of observatories such as the Pan-STARRS and LSST a…
Gravitational Lensing in Standard and Alternative Cosmologies
Margarita Safonova
This thesis contributes to the field of gravitational lensing (GL) and observational cosmology. We discuss the use of gravitational lensing as a tool in search of exotic objects in…
Cosmological Tests for a Linear Coasting Cosmology
Abha Dev, Margarita Safonova, Deepak Jain +1
A strictly linear evolution of the scale factor is a characteristic feature in several classes of alternative gravity theories. In this article we investigate the overall viability…
Macrolensing signatures of large-scale violations of the weak energy condition
Margarita Safonova, Diego F. Torres, Gustavo E. Romero
We present a set of simulations of the macrolensing effects produced by large-scale cosmological violations of the energy conditions. These simulations show how the appearance of a…
Gravity balls in induced gravity model - 'gravitational lens' effects
M. V. Safonova, D. Lohiya
In non-minimally coupled effective gravity theories one can have non-topological solitonic solutions. A typical solution is a spherical region with outside and havi…
