Join us for the launch of the Yale IPCH Public Talks: a series dedicated to exploring global perspectives and critical developments that impact cultural heritage preservation. In this inaugural event, this distinguished expert panel will contextualize the highly anticipated John Randle Centre for Yoruba History and Culture within the economic, social, and cultural landscape of Lagos, the most populous city on the African continent.
Join us on April 22nd from 10:30am-12pm in ESC 110 (21 Sachem St.) for a moderated panel followed by small group discussions on nuclear weapons.
The Wright Lab community is invited to a weekly meeting on Mondays at 9:30 a.m to hear about and discuss what is going on at the lab.
Abstract: nEXO is a proposed tonne scale liquid xenon time projection chamber which plans to search for the neutrinoless double beta decay (0vbb) of Xe-136. 0vbb is a hypothetical nuclear process in which two neutrons decay into two protons and two electrons, with the notable absence of any neutrinos. Discovery of this hypothetical phenomena would help answer several questions concerning the mass of the neutrino, such as their Majorana nature. nEXO’s proposed detector design would allow it to search for this interaction with a half-life sensitivity greater than 10^{28} yrs.
Abstract: 21cm observations of the Cosmic Dawn and Epoch of Reionization, via intensity mapping at z>6, offer a unique and exciting probe into the physics of stellar and galaxy formation and even cosmology. A range of instruments across the globe, including the highly targeted HERA experiment, are currently amassing a wealth of data – in which is buried the signature of the birth of the first stars.
Abstract: Detection mechanisms for low mass bosonic dark matter candidates, such the axion or hidden photon, leverage potential interactions with electromagnetic fields, whereby the dark matter (of unknown mass) on rare occasion converts into a single photon. Current dark matter searches operating at microwave frequencies use a resonant cavity to coherently accumulate the field sourced by the dark matter and a near standard quantum limited (SQL) linear amplifier to read out the cavity signal.
Abstract: Intensity mapping of redshifted 21cm emission from neutral hydrogen holds great promise for learning about cosmology, as it provides an efficient way to map large volumes of the universe without the need to characterize individual luminous sources. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a cylinder telescope located in Western Canada that was custom-built for this purpose, and that has collected several hundred days’ worth of data since it reached full observational capacity in late 2018.
Heavy ion collisions at the LHC and RHIC produce a quark gluon plasma (QGP), in which quarks and gluons are deconfined into an extended medium. This “fourth phase” of matter is also believed to have been the first material phase of the universe following the Big Bang. In experiment, high energy partons scatter at short time scales and may subsequently lose energy, or are “quenched”, via interactions with the QGP.
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has been able to reach the one-tonne mass scale. The detector, located at the LNGS in Italy, consists of an array of 988 TeO2 crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics data run in 2017 at a base temperature of about 10 mK and in April 2021 released its 3rd result of the search for 0νββ, corresponding to a tonne-year of TeO2 exposure.
