Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

Joint Special RPM and INPA Seminar | Chelsea Bartram (U of Washington)

March 4, 2022 @ 12:00 pm - 1:00 pm

Location: via Zoom

Speaker: Chelsea Bartram (U. of Washington)

Title: “Combing the Cosmos: A Deep Dive Into the Nature of (Dark) Matter and Fundamental Symmetries”


One of the most striking mysteries in modern astrophysics manifests itself as an absence of matter needed to form a narrative consistent with our current understanding of the universe. A promising candidate for the so-called ‘dark matter’ is the axion, whose wave-like nature requires unique technology to detect. The Axion Dark Matter eXperiment (ADMX) leverages the inverse Primakoff effect to search for axions using an ultra-low noise receiver chain and microwave cavity in a strong magnetic field. If discovered, the axion could not only solve the dark matter problem, but also resolve the Strong CP problem. Fundamental symmetries have been at the center of many deep astrophysical questions. As such, they have served as a driving force behind my research, motivating my graduate search for CP- and CPT-violation in the lepton sector, as well as my post-doctoral work in axion dark matter. I present my prior research and explain how it fits into my larger ambition to understand the
large-scale structure and composition of the universe with CMB-S4.
