    • Black Hole Bound States in AdS(3) x S**2 

      de Boer, Jan; Denef, Frederik; El-Showk, Sheer; Messamah, Ilies; Van den Bleeken, Dieter (Institute of Physics, 2008)
      We systematically construct the geometries dual to the 1+1 dimensional (0, 4) conformal field theories that arise in the low-energy description of wrapped M5-branes in S<sup>1</sup> × CY<sub>3</sub> compactifications of ...
    • Black Hole Superradiance From Kerr/CFT 

      Bredberg, Irene; Hartman, Thomas; Song, Wei; Strominger, Andrew E. (Springer Verlag, 2010)
      The superradiant scattering of a scalar field with frequency and angular momentum (w,m) by a near-extreme Kerr black hole with mass and spin (M, J) was derived in the seventies by Starobinsky, Churilov, Press and Teukolsky. ...
    • CFT Duals for Extreme Black Holes 

      Hartman, Thomas; Murata, Keiju; Nishioka, Tatsuma; Strominger, Andrew E. (Institute of Physics Publishing, 2009)
      It is argued that the general four-dimensional extremal Kerr-Newman-AdS-dS black hole is holographically dual to a (chiral half of a) two-dimensional CFT, generalizing an argument given recently for the special case of ...
    • Chiral Gravity in Three Dimensions 

      Li, Wei; Song, Wei; Strominger, Andrew E. (Springer, 2008)
      Three dimensional Einstein gravity with negative cosmological constant \(-1/\ell^2\) deformed by a gravitational Chern-Simons action with coefficient \(1/\mu\) is studied in an asymptotically \(AdS_3\) spacetime. It is ...
    • The Dynamics and Evolution of Supermassive Black Holes in Merging Galaxies 

      Blecha, Laura Elizabeth (2012-08-03)
      This thesis is a theoretical study of supermassive black holes (SMBHs) in merging galaxies. We consider the dynamics that govern inspiralling SMBH pairs and gravitational-wave (GW) recoiling SMBHs, as well as the fueling ...
    • Effect of Curvature Squared Corrections to Gravitational Action on Viscosity-to-Entropy Ratio of the Dual Gauge Theory 

      Petrov, Pavel (2013-03-06)
      In this thesis we study the properties of strongly-coupled large-N conformal field theories (CFT’s) using AdS/CFT correspondence. Chapter 1 serves as an introduction. In Chapter 2 we study the shear viscosity of strongly-coupled ...
    • The Einstein and the Navier-Stokes Equations: Connecting the Two 

      Bredberg, Irene (2013-02-22)
      This thesis establishes a precise mathematical connection between the Einstein equations of general relativity and the incompressible Navier-Stokes equation of fluid dynamics. We carry out a holographic analysis which ...
    • Exact Solutions for Supersymmetric Stationary Black Hole Composites 

      Bates, Brandon; Denef, Frederik (Springer, 2011)
      Four dimensional N = 2 supergravity has regular, stationary, asymptotically flat BPS solutions with intrinsic angular momentum, describing bound states of separate extremal black holes with mutually nonlocal charges. Though ...
    • Extremal Limits and Black Hole Entropy 

      Carroll, Sean; Johnson, Matthew; Randall, Lisa (Springer, 2009)
      Taking the extremal limit of a non-extremal Reissner-Nordstrom black hole (by externally varying the mass or charge), the region between the inner and outer event horizons experiences an interesting fate--while this region ...
    • Holographic Derivation of Kerr-Newman Scattering Amplitudes for General Charge and Spin 

      Hartman, Thomas; Song, Wei; Strominger, Andrew E. (Springer, 2010)
      Near-superradiant scattering of charged scalars and fermions by a near-extreme Kerr-Newman black hole and photons and gravitons by a near-extreme Kerr black hole are computed as certain Fourier transforms of correlators ...
    • Hot Accretion Flows Around Black Holes 

      Yuan, Feng; Narayan, Ramesh (Annual Reviews, 2014)
      Black hole accretion flows can be divided into two broad classes: cold and hot. Cold accretion flows, which consist of cool optically thick gas, are found at relatively high mass accretion rates. Prominent examples are the ...
    • Numerical Simulations of Super-Eddington Accretion Disks and Their Application to Tidal Disruption Events 

      Curd, Brandon (2022-11-23)
      One of the major channels by which supermassive black holes (SMBHs) in the universe grow is through devouring stars in their host galaxy. The disruption of a star by a SMBH and subsequent disk formation appears as a bright ...
    • One-loop Partition Functions of 3D Gravity 

      Giombi, Simone; Maloney, Alexander; Yin, Xi (Springer Verlag, 2008)
      We consider the one-loop partition function of free quantum field theory in locally Anti-de Sitter space-times. In three dimensions, the one loop determinants for scalar, gauge and graviton excitations are computed explicitly ...
    • Reflection Positivity and Monotonicity 

      Jaffe, Arthur Michael; Ritter, Gordon (American Institute of Physics, 2008)
      We prove general reflection positivity results for both scalar fields and Dirac fields on a Riemannian manifold, and comment on applications to quantum field theory. As another application, we prove the inequality \(C_D ...
    • Split States, Entropy Enigmas, Holes and Halos 

      Denef, Frederik; Moore, Gregory W. (Springer, 2011)
      We investigate degeneracies of BPS states of D-branes on compact Calabi-Yau manifolds. We develop a factorization formula for BPS indices using attractor flow trees associated to multicentered black hole bound states. This ...
    • The first pieces of the gravitational-wave progenitor population puzzle 

      van Son, Angelieke (2023-05-12)
      The first gravitational wave (GW) observation marked a monumental moment in science and heralded the birth of a new field: GW astronomy. Since then, the field has rapidly developed, with about 90 mergers of binary black ...
    • Tidal Disruption of Stars by Supermassive Black Holes 

      Stone, Nicholas Chamberlain (2013-09-16)
      This thesis presents theoretical results on the tidal disruption of stars by supermassive black holes (SMBHs). The multiwavelength ares produced by tidal disruption events (TDEs) have supernova-like luminosities, and ...
    • Wall-Crossing from Supersymmetric Galaxies 

      Andriyash, Evgeny; Denef, Frederik; Jafferis, Daniel Louis; Moore, Gregory W. (Springer, 2012)
      We give an elementary physical derivation of the Kontsevich-Soibelman wall crossing formula, valid for any theory with a 4d N = 2 supergravity description. Our argument leads to a slight generalization of the formula, which ...
    • Wilsonian Approach to Fluid/Gravity Duality 

      Bredberg, Irene; Keeler, Cynthia; Lysov, Vyacheslav; Strominger, Andrew E. (Springer, 2011)
      The problem of gravitational fluctuations confined inside a finite cutoff at radius \(r=r_c\) outside the horizon in a general class of black hole geometries is considered. Consistent boundary conditions at both the cutoff ...
    • Wrapped \(M2/M5\) Duality 

      Guica, Monica; Strominger, Andrew E. (Institute of Physics, 2009)
      A microscopic accounting of the entropy of a generic 5D supersymmetric rotating black hole, arising from wrapped \(M2\)-branes in Calabi-Yau compactified \(M\)-theory, is an outstanding unsolved problem. In this paper we ...
