[astroseminar at Sapienza] Gravity-theory Seminar: March 1st @4pm -Elisa Maggio (AEI) - Tests of general relativity in the nonlinear regime

[Paolo Pani]

PS: for those who cannot attend in person, we will also have a streaming
using Conversi's zoom link:

The seminar will start in ~1hr.

Best,
Paolo
