    • Gratitude: A Tool for Reducing Economic Impatience 

      DeSteno, David; Li, Ye; Dickens, Leah; Lerner, Jennifer (SAGE Publications, 2014)
      The human mind tends to excessively discount the value of delayed rewards relative to immediate ones, with “hot” affective processes believed to drive desires for short-term gratification. Supporting this view, recent ...
    • Gravelot's illustrations for "La nouvelle Héloïse" 

      Hofer, Philip (Harvard Library, 1960)
    • Graveyards on the Move: The Spatio-Temporal Distribution of Dead Ophiocordyceps-Infected Ants 

      Pontoppidan, Maj-Britt; Himaman, Winanda; Hywel-Jones, Nigel L.; Boomsma, Jacobus J.; Hughes, David Peter (Public Library of Science, 2009)
      Parasites are likely to play an important role in structuring host populations. Many adaptively manipulate host behaviour, so that the extended phenotypes of these parasites and their distributions in space and time are ...
    • Gravitational Collapse of Colloidal Gels 

      Manley, S.; Skotheim, J. M.; Mahadevan, L.; Weitz, D. A. (American Physical Society, 2005)
      We present a unified framework for understanding the compaction of colloidal gels under their own weight. The dynamics of the collapse are determined by the value of the gravitational stress σ(g), as compared to ...
    • Gravitational Lensing of the Sloan Digital Sky Survey High‐Redshift Quasars 

      Wyithe, J. Stuart B.; Loeb, Abraham (American Astronomical Society, 2002)
      We predict the effects of gravitational lensing on the color-selected flux-limited samples of z(s) similar to 4.3 and zs e 5 : 8 quasars, recently published by the Sloan Digital Sky Survey (SDSS). Our main findings are the ...
    • Gravitational memory, BMS supertranslations and soft theorems 

      Strominger, Andrew E.; Zhiboedov, Alexander (Springer Science + Business Media, 2016)
      The transit of a gravitating radiation pulse past arrays of detectors stationed near future null infinity in the vacuum is considered. It is shown that the relative positions and clock times of the detectors before and ...
    • Gravitational microlensing of gamma-ray burst afterglows by single and binary stars 

      Mao, Shude; Loeb, Abraham (American Astronomical Society, 2001)
      We calculate the magnification light curves caused by stellar microlensing of gamma-ray burst (GRB) afterglows. A GRB source appears on the sky as a thin ring that expands faster than the speed of light and is maximally ...
    • Gravitational Stability of Suspensions of Attractive Colloidal Particles 

      Kim, Chanjoong; Liu, Yaqian; Kühnle, Angelika; Hess, Stephan; Viereck, Sonja; Danner, Thomas; Mahadevan, L.; Weitz, David A. (American Physical Society, 2007)
      Colloidal suspensions are susceptible to gravitationally induced phase separation. This can be mitigated by the formation of a particle network caused by depletion attraction. The effectiveness of this network in supporting ...
    • Gravitational Wave Astronomy in the LSST Era 

      Coughlin, Michael William (2016-10-19)
      Optimizing the science of astronomical observatories such as gravitational-wave detectors and large telescopes maximizes their potential science output. In this thesis, I present the results from a number of analyses related ...
    • Gravitational wave detection with optical lattice atomic clocks 

      Kolkowitz, S; Pikovski, Igor; Langellier, Nicholas Ryan; Lukin, Mikhail D.; Walsworth, Ronald Lee; Ye, J. (American Physical Society (APS), 2016)
      We propose a space-based gravitational wave (GW) detector consisting of two spatially separated, drag-free satellites sharing ultrastable optical laser light over a single baseline. Each satellite contains an optical lattice ...
    • Gravitational wave heating of stars and accretion discs 

      Li, Gongjie; Kocsis, Bence; Loeb, Abraham (Oxford University Press, 2012)
      We investigate the electromagnetic counterpart of gravitational waves (GWs) emitted by a supermassive black hole binary (SMBHB) through the viscous dissipation of the GW energy in an accretion disc and stars surrounding ...
    • Gravitational waves from scattering of stellar-mass black holes in galactic nuclei 

      O'Leary, Ryan M.; Kocsis, Bence; Loeb, Abraham (Oxford University Press, 2009)
      Stellar-mass black holes (BHs) are expected to segregate and form a steep density cusp around supermassive black holes (SMBHs) in galactic nuclei. We follow the evolution of a multimass system of BHs and stars by numerically ...
    • Gravitational Waves From the Kerr/CFT Correspondence 

      Porfyriadis, Achilleas (2016-05-18)
      Astronomical observation suggests the existence of near-extreme Kerr black holes in the sky. Properties of diffeomorphisms imply that dynamics of the near-horizon region of near-extreme Kerr are governed by an infinite-dimensional ...
    • Gravitational waves from warped spacetime 

      Randall, Lisa; Servant, Géraldine (Springer Verlag, 2007)
      We argue that the RSI model can provide a strong signature in a gravitational waves. This signal is a relic stochastic background generated during the cosmological phase transition from an AdS-Schwarschild phase to the RS1 ...
    • Gravity Induced C-Deformation 

      Ooguri, Hirosi; Vafa, Cumrun (International Press, 2003)
      We study F-terms describing coupling of the supergravity to N = 1 supersymmetric gauge theories which admit large N expansions. We show that these F-terms are given by summing over genus one non-planar diagrams of the large ...
    • The Gravity of Unwanted Thoughts: Asymmetric Priming Effects in Thought Suppression 

      Najmi, Sadia; Wegner, Daniel (Elsevier, 2008)
      An unwanted thought appears to be cued easily by reminders in the environment but often the thought itself seems to cue nothing more than the desire to eliminate it from consciousness. This unusual asymmetry in the way ...
    • The Gravity Probe B test of general relativity 

      Everitt, C W F; Muhlfelder, B; DeBra, D B; Parkinson, B W; Turneaure, J P; Silbergleit, A S; Acworth, E B; Adams, M; Adler, R; Bencze, W J; Berberian, J E; Bernier, R J; Bower, K A; Brumley, R W; Buchman, S; Burns, K; Clarke, B; Conklin, J W; Eglington, M L; Green, G; Gutt, G; Gwo, D H; Hanuschak, G; He, X; Heifetz, M I; Hipkins, D N; Holmes, T J; Kahn, R A; Keiser, G M; Kozaczuk, J A; Langenstein, T; Li, J; Lipa, J A; Lockhart, J M; Luo, M; Mandel, I; Marcelja, F; Mester, J C; Ndili, A; Ohshima, Y; Overduin, J; Salomon, M; Santiago, D I; Shestople, P; Solomonik, V G; Stahl, K; Taber, M; Van Patten, R A; Wang, S; Wade, J R; Worden, P W; Bartel, N; Herman, L; Lebach, D E; Ratner, M; Ransom, R R; Shapiro, Irwin I.; Small, H; Stroozas, B; Geveden, R; Goebel, J H; Horack, J; Kolodziejczak, J; Lyons, A J; Olivier, J; Peters, P; Smith, M; Till, W; Wooten, L; Reeve, W; Anderson, M; Bennett, N R; Burns, K; Dougherty, H; Dulgov, P; Frank, D; Huff, L W; Katz, R; Kirschenbaum, J; Mason, G; Murray, D; Parmley, R; Ratner, M I; Reynolds, G; Rittmuller, P; Schweiger, P F; Shehata, S; Triebes, K; VandenBeukel, J; Vassar, R; Al-Saud, T; Al-Jadaan, A; Al-Jibreen, H; Al-Meshari, M; Al-Suwaidan, B (IOP Publishing, 2015)
      The Gravity Probe B mission provided two new quantitative tests of Einstein's theory of gravity, general relativity (GR), by cryogenic gyroscopes in Earth's orbit. Data from four gyroscopes gave a geodetic drift-rate of ...
    • Gravity waves from extreme-mass-ratio plunges into Kerr black holes 

      Hadar, Shahar; Porfyriadis, Achilleas; Strominger, Andrew E. (American Physical Society (APS), 2014)
      Massive objects orbiting a near-extreme Kerr black hole quickly plunge into the horizon after passing the innermost stable circular orbit. The plunge trajectory is shown to be related by a conformal map to a circular orbit. ...
    • Gravity waves from the Kerr/CFT correspondence 

      Porfyriadis, Achilleas; Strominger, Andrew E. (American Physical Society (APS), 2014)
      Dynamics at large redshift near the horizon of an extreme Kerr black hole are governed by an infinite-dimensional conformal symmetry. This symmetry may be exploited to analytically, rather than numerically, compute a variety ...
    • Gray anatomy: Phylogenetic patterns of somatic gonad structures and reproductive strategies across the Bilateria 

      Extavour, Cassandra G. (Oxford University Press (OUP), 2007)
      The last common ancestor of extant bilaterian animals is often referred to as ‘‘Urbilateria’’. Comparative studies of development in a variety of laboratory animals, both traditional model systems and newer ‘‘emerging’’ ...
