Abstract: I will discuss my recent work on the distributions of baryonic matter on various scales, from the gas and galaxies in galaxy clusters to the clustering of massive galaxies on large scales. Near the virial radius of galaxy clusters, …
Abstract: The Atacama B-mode Search (ABS) was a crossed-Dragone telescope located at an elevation of 5200 m in the Atacama Desert in Chile that observed the cosmic microwave background (CMB) from February 2012 until October 2014. ABS searched for the primordial B-mode polarization signal …
Abstract: I will discuss the discovery of two pentaquark states both decaying into a J/ψ meson and a proton. The decay mode defines the quark content as c cbar, u, u, d, and thus are called charmonium pentaquarks. These exotic …

Abstract: Understanding the properties of the newly-discovered Higgs boson has been one of the priorities of the LHC physics program. In this talk, I will present the measurement of Higgs boson production processes in the diphoton decay channel using 4.5/fb …
Abstract: The LHC gives us access to the highest collider energies, at the highest intensities, providing a unique opportunity to thoroughly examine the constituents of matter and their interactions at ever smaller distances and higher mass scales. Jets are produced …
Abstract: Quarks and gluons hadronize before their properties can be directly measured. However, information about the origin, electric charge, and color charge of high energy quarks and gluons is embedded in the resulting collimated sprays of hadrons known as jets. …
Abstract: Measurements of weak gravitational lensing (coherent shape distortions of distant galaxies due to the lensing effect of mass between us and those galaxies) and are among the most promising ways to learn about the equation of state of dark …
Abstract: The discovery of the Higgs in Run 1 of the LHC provided a more complete picture of the Standard Model and also gave particle physicists a new tool to use in the search for Beyond the Standard Model physics. …
