Скачать или смотреть The Millimetre Sky from the Atacama Cosmology Telescope

2021-05-13 - IoA Colloquium (remote) by Jo Dunkley
I will show new maps of the sky using data from the Atacama Cosmology Telescope, and describe how they are advancing our knowledge of cosmology, through a refined measurement of the Cosmic Microwave Background, as well as providing a new window on the millimetre sky. I will show how the data let us weigh in on the LCDM cosmological model, while also providing a sample of thousands of galaxy clusters, and revealing invisible mass and the distribution of gas around groups of galaxies. These new arcminute-resolution maps of the sky, and future refinements with next-generation observations, promise to not only test cosmology but also teach us about the Galactic interstellar medium, blazars, and the transient millimetre sky.
