Probing the nature of dark energy with 21-cm intensity mapping.
(2020)Two approaches to measure the BAOs (baryon acoustic oscillations) with optical and radio telescopes, namely; galaxy redshift and intensity mapping (IM) surveys have been introduced and discussed in the literature. Among ... -
Star formation as a function of environment in the MeerKAT Galaxy Clusters Legacy Survey.
(2023)Probing the star formation (SF) activity of cluster galaxies paves an important path towards the understanding of cluster evolution. This thesis presents the study of star formation rates (SFR) in clusters using ... -
Studying the evolution of cold gas in galaxies : large absorption line survey with MeerKAT.
(2016)Abstract available in PDF file. -
Using machine learning techniques to identify strong gravitational lensing systems in DES.
(2021)Gravitational lensing systems enable astronomers to look into the distant universe by magnifying distant objects. Strong gravitational lensing systems are an incredibly rare phenomenon, with only a total about 1; 000 ...
