Jun 13, 2024 · We present the Black Hole Explorer (BHEX), a mission that will produce the sharpest images in the history of astronomy by extending submillimeter Very-Long-Baseline Interferometry (VLBI) to space.
2 days ago · In a paper from 1996, Andrew Strominger and Cumrun Vafa showed how to derive the Bekenstein–Hawking formula for certain black holes in string theory. Their calculation was based on the observation that D-branes—which look like fluctuating membranes when they are weakly interacting—become dense, massive objects with event horizons when the ...
Jun 13, 2024 · We will confront the LISA observation window to massive black hole binary mergers' population forecasted with the state-of-the-art population models and evaluate the odds and the expected accuracies regarding GW memory observations in the LISA lifetime.
Jun 18, 2024 · Recently, a quantum mechanical theory of quantum spaces described by a large N N non-commutative coordinates is proposed as a theory for quantum gravity [1]. In this paper, we construct Kerr black hole as a rotating noncommutative geometry solution of this theory.
Jun 21, 2024 · We present the motivation and vision for the Black Hole Explorer (BHEX), a mission that will extend submillimeter Very Long Baseline Interferometry (VLBI) to space.
Jun 14, 2024 · In string theory a spacetime vacuum is encoded by a sigma-model 2-dimensional SCFT. In heterotic string theory that SCFT is assumed to be the sum of a supersymmetric chiral piece and a non-supersymmetric piece (therefore “heterotic”).
