The NAS Cosmology Group research focuses on dark energy, modified gravity, and loop quantum cosmology. Our goal is to gain a better understanding of these topics and to develop new theories and models that can help explain the mysteries of the universe. 

Research Areas

Dark Energy:

Dark energy is a mysterious component of the universe thought to be responsible for the accelerating expansion of the cosmos. Current cosmological observations also reveal tension between measurements of various cosmological parameters. The NAS Cosmology Group focuses on studying the nature and properties of dark energy, as well as the origin and resolution of cosmological tensions. We aspire to develop new theories and models that can elucidate this enigmatic component and alleviate the current tensions in cosmology. Through our research, the group aims to make contributions to the broader field of cosmology and deepen our understanding of the universe and its evolution.

Modified Gravity:

Modified gravity is an alternative theory of gravity that seeks to explain the observed phenomena in the universe without invoking dark energy. The NAS Cosmology Group is focused on researching modified gravity in order to better understand its properties and possible implications for our understanding of the universe. Through our research, the group hopes to contribute to the development of new theories and models that can help explain the mysteries of the cosmos.

Quantum Cosmology:

Quantum gravity is one of the stunning issues of modern theoretical physics. Loop quantum gravity (LQG) is a tentative candidate based on background independent non-perturbative approach to quantize gravity. Two main applications of LQG are blackhole and cosmology. The techniques of LQG when applied to gauge reduced cosmological spacetime is popularly called loop quantum cosmology (LQC) in the community.
