Speaker: Michael Fedderke, Stanford University / University of California, Berkeley / LBNL Abstract: In this talk, I will detail two ways to search for low-mass axion dark matter using cosmic microwave background (CMB) polarization measurements. These appear, in particular, to be some of the most promising ways to directly detect fuzzy dark matter. Axion dark matter causes rotation of the polarization of light passing through it. This gives rise to two novel phenomena in the CMB. First, the late-time oscillations... More »

Speaker: Gabrijela Zaharijas, University of Nova Gorica, Slovenia Abstract: High-energy gamma rays are among the most promising tools to constrain or reveal the nature of dark matter, in particular the Weakly Interacting Massive Particles (WIMP) models. The Cherenkov Telescope Array (CTA) is well into its pre-construction phase and will soon probe the high-energy gamma-ray sky in the 20 GeV - 300 TeV energy range. Thanks to its improved energy and angular resolutions, as well as, significantly larger effective area when... More »

Miguel Escudero Abenza, King’s College London Abstract: In this talk, based on arXiv:1810.00880, I will present a new mechanism of Baryogenesis and dark matter production in which both the dark matter relic abundance and the baryon asymmetry arise from neutral B meson oscillations and subsequent decays. In the early Universe, decays of a long-lived particle produce B mesons and anti-mesons out of thermal equilibrium. These mesons/anti-mesons then undergo CP violating oscillations before quickly decaying into visible and dark sector particles.... More »

Speaker: Peter Shirron, PhD, NASA/Goddard Space Flight Center Space Cryogenics: Perspectives and New Challenges Cryogenics has always been a foundational element of NASA space program, but it far more critical now with the growing use of ultra-low temperature detectors in x-ray, infrared and sub-millimeter telescopes. Cryogenic systems are becoming very complex as the size of telescopes and focal plane arrays expand, and the cooling requirements become more challenging: lower operating temperature (below 50 millikelvin), continuous operation and long lifetime. The... More »

All Fermilab employees and users are welcome to attend. This summer, the Integrated Engineering Research Center that will be adjacent to Wilson Hall will be breaking ground. Construction will require closing of the Wilson Hall east parking lot and the rerouting of vehicle traffic. A lab working group has been developing and evaluating short-term and long-term solutions. Please join members of the Parking Working Group to discuss upcoming parking changes to the core campus at one of the following brown... More »
