The Atacama Cosmology Telescope: Detection of mm-wave transient sources

Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Nick Battaglia, J. Richard Bond, Erminia Calabrese, Steve K. Choi | Summary: We report on the serendipitous discovery of three transient mm-wave sources using data from the Atacama Cosmology Telescope. The first, detected at RA = 273.8138, dec = -49.4628 at ${sim}50sigma$ total, brightened from […]

Path-Dependent Supercooling of the $^3$He Superfluid A-B transition

Kavli Affiliate: Jeevak Parpia | First 5 Authors: Dmytro Lotnyk, Anna Eyal, Nikolay Zhelev, Abhilash Sebastian, Yefan Tian | Summary: We examine the discontinuous first-order superfluid $^3$He A to B transition in the vicinity of the polycritical point (2.232 mK and 21.22 bar). We find path-dependent transitions: cooling at fixed pressure yields a well defined […]
