Tracing Cosmological Signature with Doppler Lensing: Insights from Cosmological Simulations
Mubtasim Fuad, Sonia Akter Ema, Md Rasel Hossen
Doppler lensing, a relativistic effect resulting from the peculiar velocities of galaxies along the line of sight, provides insight into the large-scale structure of the Universe.…
