VIRTUAL INPA SEMINAR | Scott Kravitz (LBNL)

Speaker: Scott Kravitz (LBNL)    Title: CrystaLiZe - Solid Xenon Detector R&D   Abstract:  Radon and its daughter decays limit the sensitivity of direct WIMP dark matter searches, despite extensive screening programs, careful material selection and specialized Rn-reduction systems. For xenon time projection chambers, a means to surpass this constraint may lie in crystallizing the xenon. In […]

Speaker: Anton Baleato Lizancos (Cambridge) Title: “Understanding biases to CMB lensing and delensing on the road to precision science” Abstract: For cosmologists, CMB lensing can be both a blessing and a nuisance. It's a nuisance because it generates spurious B-mode polarisation which obscures the highly-sought-after signal from inflationary gravitational waves, but it's a blessing because […]
