Abstract:

I will discuss black hole solutions in massive (bi)-gravity. A method for constructing black hole metrics in massive (bi)-gravity will be presented, in particular I will show analogues of Schwarzschild, Reissner Nordstrom, Kerr and Kerr Newman black holes. In the second part of my talk I will discuss classical stability of two different branches of spherically symmetric solutions in massive (bi)-gravity. I will show that the bi-diagonal branch possesses unstable mode featuring the Gregory-Laflamme instability.
