Cosmology Personal Statement

My interest in physics and astronomy began in my childhood years, but there were some moments which had enormous impacts in this predilection. It all started when I was in the first year of middle school. I was watching a TV program called 'Night Sky', which had invited an astrophysicist to explain to the general audience about astronomy and cosmology projects, history of them and their results and impacts on our perception of the universe. He mainly talked about 'Cosmic Background Explorer' (COBE) and how it supports Hot Bing Bang model; additionally, he mentioned relatively recent project at that time 'Two-degree Field Galaxy Redshift Survey' (2dFGRS) and how it provides supports for Dark Matter. When the program finished, I felt stunned;

V.Karimipour on Quantum Graphity, which is a quantum gravity model (based on quantum information) for an emergent locality. I worked on the quantum informational aspects of it, and I represented them on the weekly doctoral seminars of the Quantum Information Science (QIS) group at SUT. The current research is mostly about the hamiltonian gauge theory and topological changes from high energy to low energy of the theory in order to work out cosmological observables and their evolutions. My main area of research with Prof. S.Baghram is 21cm cosmology. I found this subject really interesting and promising; since, it involves various astrophysical processes and it has enormous cosmological impacts and applications; capability to use this unique radiation as a probe for Epoch of Reionization (EoR) and primordial structures and near future observations by Square Kilometre Array (SKA) are making this subject more exhilarating. Particularly, I am working on the effects of Redshift Space Distortion (RSD) and astrophysical processes such as Wouthuysen–Field Coupling on the 21cm signatures, particularly at EoR. Moreover, my most recent focus is on using 21cm radiation as a probe to test General Relativity and some models of Modified Gravity by using weak gravitational lensing of 21cm in EoR and Galaxy clustering surveys. Additionally, as a member of Cosmology group of SUT, I had several talks and representation in different seminars of the

And the department’s works in these areas are quite fascinating. In particular, I am interested in works of Prof. E.L. Blanton on galaxy clusters and the physics of their environment and particularly early clusters, works of Prof. A.P. Marscher on Blazers, especially radiative processes and gamma-ray radiation of them, works of Prof. T.G. Brainerd on weak gravitational lensing and galaxies orientation within their dark matter halos. Moreover, the department has remarkable faculties in diverse areas of astronomy and astrophysics, which makes a wonderful opportunity for being informed about progress in observational, computational, theoretical aspects of astronomy and astrophysics. Furthermore, I found the courses of this program quite relevant to my interests, and they are being taught by renowned experts in those areas, which make this program a magnificent place for studying. Another extremely imperative factor for doing research is the department access to research facilities like different Telescopes and The Green High-Performance Computing Center. For all these reasons, this program would be an auspicious start for my academic career and being a part of your program would be an honor for
