NPA Seminar: Adriaan Duivenvoorden, Flatiron Institute; Simons Foundation, "Cosmology from the fine details of the microwave sky with the Atacama Cosmology Telescope and the Simons Observatory"

Modern ground-based microwave observatories offer a high-resolution perspective on the cosmic microwave background (CMB) and its secondary components, complementing galaxy surveys and the low resolution CMB data from the Planck and WMAP satellites. In this talk, I will introduce two such observatories, the Atacama Cosmology Telescope (ACT) and the Simons Observatory. The ACT collaboration is preparing to release its sixth public data release. This release, DR6, is the result from a 6-year-long survey covering 40% of the sky at arcminute resolution.

NPA Seminar: Deepa Thomas, The University of Texas at Austin, "Probing hot QCD matter with charm and beauty quarks"

Ultra-relativistic heavy-ion collisions produce a hot and dense QCD matter, called Quark-Gluon Plasma (QGP). Unlike in ordinary matter, quarks and gluons are not confined within short distances but can roam freely over distances larger than the hadronic scale in the state of QGP. Understanding this novel state of matter offers a new way to learn how quarks and gluons bind to form stable particles like the proton.

NPA Seminar: Stephen Kuenstner, Boston University, "Sensitive Searches for Axion Dark Matter with Solid-State Spin Ensembles"

In this talk, I’ll describe how we use solid-state spin ensembles, magnetic resonance, and quantum sensing techniques to search for axion dark matter in the third-generation CASPEr-e detector. Discovering and characterizing axion dark matter could resolve the longstanding Strong CP Problem, in addition to revealing the identity of dark matter. The Strong CP Problem stems from the puzzling lack of a CP-violating permanent electric dipole moment (EDM) in nucleons.

NPA Seminar: Bryan Ramson, Fermilab, "The New Era of Precision Neutrino Physics"

Long-baseline neutrino oscillation experiments present some of the most compelling paths toward physics beyond the standard model. Measurement of the leptonic mixing matrix through oscillation and observation of the degree of leptonic CP violation demonstrates a proof of concept for understanding the difference between matter and anti-matter in the observable universe. State of the art experiments like NOvA and T2K are currently performing measurements of neutrino oscillation, but ultimately, will be statistically limited.
