A Study of Abell 2146: Dark and Luminous
The universe is a highly dynamic system. Under the primary inﬂuence of gravity, matter in the universe clumped together to create the structure we currently observe with our telescopes. Gravity formed objects on vastly ...
Simulation Study of Invisible Decays of the Higgs Boson with the Circular Electron Positron Collider
A Higgs-like boson has been discovered by the experiments ATLAS and CMS at the LHC. We need to verify that it is the Standard Model (SM) Higgs and understand its nature. A Circular Electron Positron Collider (CEPC), has ...
Testing the Dark Sector Versus Modified Gravity Models in Cosmology
This dissertation studies cosmological and astrophysical tests of gravity theories and the dark sectors. We focus on three tests. All of them are promising for future observations. The first test is about tensor-mode ...
Studies of Baryonic Physics and Triaxiality in Galaxy Clusters
This dissertation concerns the impact of baryonic physics and triaxiality on galaxy clusters. The first and primary portion of this work is to investigate the impact baryonic processes have on galaxy cluster masses, ...
The Structure and Environment of Galaxy Clusters in Simulations and Observations
Galaxy clusters are powerful testing grounds for cosmology. They are the largest, most massively bound objects in the Universe and can give us deep insights on how baryons, dark matter, and dark energy impacts on the ...
