I am interested in a wide variety of topics related to the study of the universe, although my research is primarily focused on Astrophysics and Plasma Physics.
Astrophysics
​
Dealing with computational big datasets with the following astrophysical topics: Gravitational Lensing, General Theory of Relativity, Cosmic Structures, Ray-tracing Methodology, Dark Matter, Dark Energy, etc. Also, implementing Machine Learning techniques to deal with big datasets.

This figure shows the full sky weak-lensing convergence map. In our inhomogeneous universe, the view of an observer will be influenced by the location and local environment. Here we analyse the one-point probability distribution functions and angular power spectra of weak-lensing (WL) convergence and magnification numerically to investigate the influence of our local environment on WL statistics in relativistic N-body simulations. Our findings demonstrate how cosmological observations of large-scale structure through WL can be impacted by the locality of the observer. The findings are described in detail in this paper.
This figure shows the variation of Doppler convergence by stacking cosmic voids having radii 20-25 Mpc/h. Probing the mass distribution of the universe requires various approaches, including weak gravitational lensing that subtly modifies the shape of distant sources, and Doppler lensing that changes the apparent size and magnitude of objects due to peculiar velocities. In this work, we adopt both gravitational and Doppler lensing effects to study the underlying matter distribution in and around cosmic voids/halos. The results of this paper show that the most optimal strategy that combines both gravitational and Doppler lensing effects to map the mass distribution should focus on the redshift range z≈0.3−0.4. The findings are described in detail in this paper.
Plasma Physics

-
space, and astrophysical plasmas;
-
multi-ion plasmas, degenerate quantum plasmas;
-
nonextensive plasmas, strongly coupled plasmas;
4. dusty/complex plasmas.

This figure shows the effects of cylindrical geometry on heavy-ion-acoustic (HIA) Kortewegde Vries (K-dV) solitons in the presence of positively charged heavy ions when both electron and light ion being non-relativistic degenerate. Here, we investigated the properties of HIA solitary structures associated with the nonlinear propagation of cylindrical and spherical electrostatic perturbations in an unmagnetized, collisionless dense plasma system. The K-dV and modified K-dV (mK-dV) equations have been derived by employing the reductive perturbation method. It has been found that the effect of degenerate pressure and number density of electron and inertial light ion fluids, and positively charged static heavy ions significantly modify the basic features of HIA solitary waves. The findings are described in detail in this paper.
