The Atacama Cosmology Telescope: DR4 Maps and Cosmological Parameters

Kavli Affiliate: Hsiao-Mei (Sherry) Cho |Summary:We present new arcminute-resolution maps of the Cosmic Microwave Background temperature and polarization anisotropy from the Atacama Cosmology Telescope, using data taken from 2013-2016 at 98 and 150 GHz. The maps cover more than 17,000 deg$^2$, the deepest 600 deg$^2$ with noise levels below 10 $μ$K-arcmin. We use the power […]

Physics Successfully Implements Lagrange Multiplier Optimization

Kavli Affiliate: Eli Yablonovitch | Summary:Optimization is a major part of human effort. While being mathematical, optimization is also built into physics. For example, physics has the principle of Least Action, the principle of Minimum Entropy Generation, and the Variational Principle. Physics also has physical annealing which, of course, preceded computational Simulated Annealing. Physics has […]

Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program

Kavli Affiliate: Chiaki Hikage | Summary:The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized to search for dual quasar candidates. Using an automated image analysis routine on 34,476 known SDSS quasars, we identify those with two (or more) […]
