Baryon acoustic oscillation and LSS formation in the nascent universe
(BRAC University, 2017)
The Cosmic Microwave Background Radiation (CMBR) and cosmological redshift are together regarded as the best available evidence for the Big Bang theory. Measurements of this radiation have made the inflationary Big Bang ...
Review of Einstein field equation solution rotational and non-rotational black holes
(BRAC University, 2017)
The origin of gravitational theory of relativity includes the discussion of Sir. Isaac Newton and Einstein’s theory of relativity. A brief derivation is introduced about the spherically symmetric solution of Einstein’s ...
The AdS-CFT correspondence and the black-hole information theory paradox
(BRAC University, 2017)
This thesis discusses the role of AdS/CFT correspondence in high-energy physics. It
concentrates on studying the mathematical black holes in various backgrounds, particularly in
the anti deSitter(AdS) space. In this ...
Nonperturbative phenomena in field theory and gravity, and use of Borel summation to capture nonperturbative information
(BRAC University, 2017-12)
This thesis addresses non-perturbative phenomena and techniques to analyze nonperturbative
problems. First, we discuss the simplest non-perturbative example in
quantum gravity: blackholes, and how they non-perturbatively ...
