Learn about the latest advancements in astronomy research in the Miller Lab, with the Sunyaev-Zel'dovich Array (SZA) and Atacama Cosmology Telescope (ACT) projects. The SZA collaboration features eight 3.5m dishes with receivers at 30GHz and 90GHz, while the ACT project boasts a 6m single-dish telescope with observing frequencies at 150GHz, 217GHz, and 270GHz. Explore the integration of SZA with OVRO and BIMA telescopes and the ACT telescope's discoveries in small-scale CMB anisotropy, SZE effect, OV effect, and CMB lensing.
