We report the first look at extragalactic Cepheid variables with James Webb Space Telescope, obtained from a serendipitous (to this purpose) observation of NGC 1365, host an SN Ia (SN 2012fr), calibration path used to measure Hubble constant. As expected, high-resolution observations NIRCam through F200W show better source separation line-of-sight companions than HST images similar near-infrare...
Suppose an urn contains M balls, of different types, which are removed from the urn in a uniform random manner. In the hypergeometric coupon collection problem, we are interested in the set of balls that have been removed at the moment when at least one ball of each type has been removed. In its dual, we are interested in the set of removed balls at the first moment that this set contains all o...
