A cosmographic analysis using DESI-DR2 and strong lensing: I. Time-Delay measurements
Darshan Kumar, Deepak Jain, Shobhit Mahajan
Strong gravitational lensing time-delay measurements, together with the distance sum rule (DSR), offer a model-independent approach to probe the geometry and expansion of the unive…
A cosmographic analysis using DESI-DR2 and strong lensing: II. Distance Ratio measurements
Darshan Kumar, Deepak Jain, Shobhit Mahajan
The distance ratios derived from strong lensing systems, combined with complementary cosmological observations, allow for the study of cosmic expansion and curvature without assumi…
Study of Various Dark Matter Halo Profiles in Milky Way and M31 Galaxies within the Standard Cosmology Framework
Darshan Kumar, Nisha Rani, Deepak Jain +2
In this paper, we study the rotation curves of the Milky Way galaxy (MW) and Andromeda galaxy (M31) by considering their bulge, disk, and halo components. We model the bulge region…
