Title: Black Holes in Massive Gravity: Time-Dependent Solutions
Abstract: When starting with a static, spherically-symmetric ansatz, there are two types of black hole solutions in massive gravity: (i) exact Schwarzschild solutions which exhibit no Yukawa suppression at large distances and (ii) solutions which contain coordinate-invariant singularities at the horizon.  In this talk, I will present new black hole solutions which have a nonsingular horizon and can potentially be matched to Yukawa asymptotics at large distances.  These solutions recover Schwarzschild black holes in the limit of zero graviton mass and are thus observationally viable.  At finite mass they depend explicitly on time.  However, the location of the apparent horizon is time-independent indicating that these black holes are neither accreting or evaporating (classically).
