  21. 5. A cost-estimation algorithm for flexible Cosmic Explorer site configurations
    Bretton Simpson (California State University, Fullerton)
    Poster

    Cosmic Explorer is a proposed next-generation gravitational wave observatory with L-shaped 40 km length arms to be paired with a widely separated second detector with arms of 20 km in length and constructed within the conterminous United States for an estimated date of first operations in the late 2030s. The objective of Cosmic Explorer is to exceed the sensitivity of LIGO to gravitational...

  22. 24. A systematic exploration of non-constant angular momentum tori around Schwarzschild-de Sitter black holes
    Sara Cesare (Scuola Superiore Meridionale)
    Poster

    It is common practice to use equilibrium toroidal configurations as initial conditions when simulating black hole accretion. However, standard models often simplify the problem by assuming the idealized hypothesis of an orbiting fluid with a uniform specific angular momentum distribution. In this work, we relax this assumption by introducing a logarithmic distribution within a Schwarzschild-de...

  23. 23. Detecting Parity Violation in the Stochastic Gravitational-Wave Background with Third-Generation Detector Networks
    Jacopo Uggeri (King's College London)
    Poster

    We investigate the prospects for detecting parity-violation in the stochastic gravitational-wave background with third-generation ground-based detector networks. We focus on a network consisting of one Einstein Telescope and two Cosmic Explorer detectors. In our analysis we vary the ET design, detector orientations, and arm lengths, in order to assess the impact of geometry and scale on...

  24. 2. Detecting single gravitons with gravitational wave detectors
    Germain Tobar (Stockholm University)
    Poster

    The quantization of gravity is widely believed to result in gravitons -- particles of discrete energy that form gravitational waves. But their detection has so far been considered impossible. In this talk, I will show that laboratory experiments can reveal signatures of single graviton exchange. I will outline how both interferometric and resonant-mass gravitational wave detectors can be...

  25. 4. Impact of the Binary Neutron Star Confusion Background on Cosmic Explorer Data Analysis
    Jake Summers (Caltech)
    Poster

    Third-generation ground-based gravitational-wave detectors such as Cosmic Explorer are expected to detect signals from compact binary coalescences at rates up to 1000 times higher than current interferometers. Many signals are therefore expected to overlap with each other in both time and frequency, forming a confusion background. In preparation for this scenario, we generate synthetic Cosmic...

  26. 26. Quadratic Coupling of Gravitational Waves in Rotating Black Hole Spacetimes
    Lennox Keeble (Wake Forest University)
    Poster

    The Einstein equations are intrinsically nonlinear. Nevertheless, gravitational waveforms from astrophysical binary black hole coalescences admit a remarkably simple hierarchy of descriptions: the inspiral is controlled by weak-field and adiabatic approximations, the late-time relaxation is governed by perturbations of the remnant Kerr black hole, with the merger smoothly interpolating between...

  27. 1. Quasinormal Modes of Black Holes Surrounded by Anisotropic Matter
    Domenica Garzon (University of Illinois Urbana-Champaign)
    Poster

    In realistic astrophysical environments, black holes are not perfectly isolated. In this work, we study black holes surrounded by anisotropic matter, where the radial and tangential pressure components are not equal. Such anisotropic matter provides a simple but physically motivated way to model environmental effects, including dark matter, early-universe topological defects, or...

  28. 25. Semiclassical corrections to thin accretion-disc photon emissions
    Francesca Darkins (Durham University), Simon Chambers-Trubatch (University of Lethbridge and Carleton College)
    Poster

    We study the behavior of photon geodesics in perturbed, non-rotating black hole metrics. The perturbations can originate from quantum gravity, gravitational waves, or other phenomena. We find that trajectories of photons emitted near the (perturbed) critical orbit are drastically altered for some such perturbations. In the case of perturbations due to quantum gravity, the number of times a...
