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.

Carlos García García (IFF, Madrid) – Theoretical priors for quintessence

December 7 @ 12:00 pm - 1:00 pm

Dark energy is a key unsolved problem. An enormous number of theories try to explain the accelerated expansion of the universe, ranging from the simplicity of a cosmological constant to the inclusion of new gravitational fields that affect space-time dynamics. We need clever methods to test the landscape of theories to make the most of next-generation experiments. I will present a novel framework to study dark energy and apply it to general quintessence models, reducing their functional freedom. Expanding the dark energy density as a truncated polynomial series, we are able to reproduce the observables with less than 1% error, with just 2 parameters. This economic yet precise description will allow dark energy to be constrained with next generation instruments in a general and efficient way.

Sessler Conference Room CA

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.
