About the INPA Seminars

All seminars are on Fridays (unless otherwise noted) and start at 12:00 (noon) with a brief presentation of the weekly scientific news. Typically the talks end by 13:00. The seminars take place in Bldg. 50A, room 5132.

The committee members are:

The following Seminar schedule for the Institute for Nuclear and Particle Astrophysics is tentative. The seminar becomes final usually a few days before the Friday of the talk.

Location: via Zoom

Speaker: Chiara Salemi (Massachusettes Institute of Technology)

Title: Seeing the Invisible: Search for Low-Mass Axion Dark Matter


Multiple astrophysical and cosmological observations have shown that the visible matter described by the Standard Model is only a small fraction of the energy in the universe. We believe that there is about five times as much dark matter, which is likely comprised of massive particles that interact very little or not at all with other matter. One of the most well-motivated candidates to be the dark matter is the axion, a hypothetical particle that is predicted by the solution to another long-standing mystery in physics, the strong CP problem. This talk presents ABRACADABRA-10 cm, the first direct search for low-mass axion dark matter, which used an innovative lumped element detection method. This prototype experiment set world-leading limits on axions and set the stage for the DOE-funded DMRadio program, a series of larger detectors that will be capable of finding axions or definitively excluding them over a large range of masses below 1 μeV.

12:00 pm - 1:00 pm

INPA guests from campus can now come up to the lab early on Fridays. The INPA Common Room (50-5026) is reserved for our guests from 10:00 am to 12:00 noon, and from 1 pm to 5 pm. Note that the seminars are now held in 50A-5132 to accommodate a larger number of attendees.

Also, on Fridays from 1:00 pm to 2:00 pm you are welcome to join the INPA Speaker for a brown-bag lunch in the small Pers Hall conference room, 54-130B.

INPA Tea Series

The Physics and Nuclear Science Divisions have together been leaders in revolutionary changes in our understanding of neutrinos and cosmology. Everyone is welcome to attend the open forum. Tea and light refreshments will be served.

INPA Common Room (50-5026)
3:30 pm
