  1. 338. Regular spacetimes: black holes, wormholes and bubbles (Invited talk)
    Sayan Kar (Indian Institute of Technology Kharagpur)
    06/12/2023, 14:15

    In this talk, I will provide a brief overview of regular spacetimes in theories of gravity. In particular, I will primarily review some of the well--known regular black holes and also discuss wormholes and bubble spacetimes. Some recent results, as well as physical effects in such spacetimes will be mentioned. We will end with
    general comments and open questions.

    Sk Jahanur Hoque (BITS Pilani, Hyderabad campus)
    08/12/2023, 14:15

    The physics of gravitational waves is well understood for asymptotically flat space-times. Asymptotic flatness presumes a vanishing cosmological constant. However, cosmological observations over the decades have indicated that our universe is undergoing an accelerated expansion, which is most simply modelled by a de Sitter universe or equivalently by a positive cosmological constant. Even a...
