Recent Submissions

  • Stellar Tidal Disruption Events in General Relativity 

    Stone, Nicholas C.; Kesden, Michael; Cheng, Roseanne M.; van Velzen, Sjoert (Springer/Plenum Publishers, 2019-02-12)
    A tidal disruption event (TDE) ensues when a star passes too close to a supermassive black hole (SMBH) in a galactic center, and is ripped apart by its tidal field. The gaseous debris produced in a TDE can power a bright ...
  • Scaffolded Training Environment for Physics Programming (STEPP) 

    Kitagawa, Midori; Fishwick, Paul Anthony; Kesden, Michael; Urquhart, Mary; Guadagno, R.; Jin, Rong; Tran, Ngoc M.; Omogbehin, Erik; Prakash, Aditya; Awaraddi, Priyanka; Hale, Baily; Suura, Ken; Raj, A.; Stanfield, J.; Vo, H. (Association for Computing Machinery, Inc, 2019-06)
    We are a year into the development of a software tool for modeling and simulation (M&S) of 1D and 2D kinematics consistent with Newton’s laws of motion. Our goal has been to introduce modeling and computational thinking ...
  • Wide Nutation: Binary Black-Hole Spins Repeatedly Oscillating from Full Alignment to Full Anti-Alignment 

    Gerosa, D.; Lima, A.; Berti, E.; Sperhake, U.; Kesden, Michael; O'Shaughnessy, R. (Institute of Physics Publishing, 2019-04-15)
    Within the framework of 2PN black-hole binary spin precession, we explore configurations where one of the two spins oscillates from being completely aligned with the orbital angular momentum to being completely anti-aligned ...
  • Explaining LIGO's Observations via Isolated Binary Evolution with Natal Kicks 

    Wysocki, Daniel; Gerosa, Davide; O'Shaughnessy, Richard; Belczynski, Krzysztof; Gladysz, Wojciech; Berti, Emanuele; Kesden, Michael; Holz, Daniel E.
    We compare binary evolution models with different assumptions about black-hole natal kicks to the first gravitational-wave observations performed by the LIGO detectors. Our comparisons attempt to reconcile merger rate, ...
  • Unified Treatment of Tidal Disruption by Schwarzschild Black Holes 

    Servin, Juan; Kesden, Michael (2017-04-03)
    Stars on orbits with pericenters sufficiently close to the supermassive black hole at the center of their host galaxy can be ripped apart by tidal stresses. Some of the resulting stellar debris becomes more tightly bound ...
  • Precessional Instability in Binary Black Holes with Aligned Spins 

    Gerosa, Davide; Kesden, Michael; O'Shaughnessy, Richard; Klein, Antoine; Berti, Emanuele; Sperhake, Ulrich; Trifiro, Daniele (2015-10-02)
    Binary black holes on quasicircular orbits with spins aligned with their orbital angular momentum have been test beds for analytic and numerical relativity for decades, not least because symmetry ensures that such ...
  • Multi-Timescale Analysis of Phase Transitions in Precessing Black-Hole Binaries 

    Gerosa, D.; Kesden, Michael; Sperhake, U.; Berti, E.; O'Shaughnessy, R. (American Physical Society, 2015-09-14)
    The dynamics of precessing binary black holes (BBHs) in the post-Newtonian regime has a strong timescale hierarchy: the orbital timescale is very short compared to the spin-precession timescale which, in turn, is much ...
  • Distinguishing Black-Hole Spin-Orbit Resonances by their Gravitational-Wave Signatures 

    Gerosa, D.; O'Shaughnessy, R.; Kesden, Michael; Berti, E.; Sperhake, U. (American Physical Society, 2014-06-24)
    If binary black holes form following the successive core collapses of sufficiently massive binary stars, precessional dynamics may align their spins, S₁ and S₂, and the orbital angular momentum L into a plane in which they ...
