We continue to review all events currently planned for the next sixty days and organizers will be notified if their event must be canceled, postponed, or held remotely. Please, check back on Indico during this time for updates regarding your meeting specifics.
As DOE O 142.3A, Unclassified Foreign Visits and Assignments Program (FVA) applies not only to physical access to DOE sites, technologies, and equipment, but also information, all remote events hosted by Fermilab must comply with FVA requirements. This includes participant registration and agenda review. Please contact Melissa Ormond, FVA Manager, with any questions.

A deci-Hz Gravitational-Wave Lunar Observatory for Cosmology

Description

We are proposing Gravitational-Wave Lunar Observatory for Cosmology (GLOC) -- a first of its kind fundamental physics experiment on the surface of the Moon. The experiment would access gravitational waves in the frequency range of deci-Hz to 5 Hz, a challenging regime for all Earth-based detectors and space missions. We find that such a lunar-based experiment can survey over $70\%$ of the observable volume of our universe without significant background contamination. This unprecedented sensitivity makes GLOC a powerful cosmic probe for Dark Energy, Dark Matter and physics beyond the Standard Model. In particular, it will independently trace the Hubble expansion rate up to redshift $z \sim 3$, provide the strongest limits on the sub-solar Dark Matter candidates and test $\Lambda$CDM cosmology up to $z\sim 100$. Furthermore, it will have a unique access to gravitational waves from Type Ia supernovae, thus aiding calibration of the standard candles.
