  • Binary black hole spectroscopy : A no-hair test of GW190814 and GW190412 
    Capano, Collin D.; Nitz, Alexander H. (College Park, MD : American Physical Society, 2020)
    Gravitational waves provide a window to probe general relativity (GR) under extreme conditions. The recent observations of GW190412 and GW190814 are unique high-mass-ratio mergers that enable the observation of gravitational-wave ...
  • Characterizing the continuous gravitational-wave signal from boson clouds around Galactic isolated black holes 
    Zhu, Sylvia J.; Baryakhtar, Masha; Papa, Maria Alessandra; Tsuna, Daichi; Kawanaka, Norita; Eggenstein, Heinz-Bernd (College Park, MD : American Physical Society, 2020)
    Ultralight bosons can form large clouds around stellar-mass black holes via the superradiance instability. Through processes such as annihilation, these bosons can source continuous gravitational-wave signals with frequencies ...
  • Deep-learning continuous gravitational waves : Multiple detectors and realistic noise 
    Dreissigacker, Christoph; Prix, Reinhard (College Park, MD : American Physical Society, 2020)
    The sensitivity of wide-parameter-space searches for continuous gravitational waves is limited by computational cost. Recently it was shown that deep neural networks (DNNs) can perform all-sky searches directly on ...
  • Detection of gravitational-wave signals from binary neutron star mergers using machine learning 
    Schäfer, Martin B.; Ohme, Frank; Nitz, Alexander H. (College Park, MD : American Physical Society, 2020)
    As two neutron stars merge, they emit gravitational waves that can potentially be detected by Earth-bound detectors. Matched-filtering-based algorithms have traditionally been used to extract quiet signals embedded in ...
  • Resolution of the colocation problem in satellite quantum tests of the universality of free fall 
    Loriani, Sina; Schubert, Christian; Schlippert, Dennis; Ertmer, Wolfgang; Pereira Dos Santos, Franck; Rasel, Ernst Maria; Gaaloul, Naceur; Wolf, Peter (College Park, MD : American Physical Society, 2020)
    A major challenge common to all Galilean drop tests of the universality of free fall (UFF) is the required control over the initial kinematics of the two test masses upon release due to coupling to gravity gradients and ...
  • Sensitivity and performance of the Advanced LIGO detectors in the third observing run 
    Buikema, A.; Cahillane, C.; Mansell, G.L.; Blair, C.D.; Abbott, R.; Adams, C.; Adhikari, R.X.; Ananyeva, A.; Appert, S.; Bode, N.; Booker, P.; Liu, J.; Meylahn, F.; Willke, B.; et al. (College Park, MD : American Physical Society, 2020)
    On April 1st, 2019, the Advanced Laser Interferometer Gravitational-Wave Observatory (aLIGO), joined by the Advanced Virgo detector, began the third observing run, a year-long dedicated search for gravitational radiation. ...
