Prof. Harald Pfeiffer (CITA, University of Toronto)17/06/2014, 08:45Theoretical Physics / Physique théorique (DTP-DPT)Invited Speaker / Conférencier invitéAdvanced Gravitational Wave Detectors like Advanced-LIGO are expected to commence searches for gravitational waves as early as 2015. One of the prime sources for these instruments is the in spiral and coalescence of binary black holes. Numerical simulations of binary black holes play an integral role in this effort, and have matured now sufficiently to begin to address the most general case...Go to contribution page

Dr Hari Kunduri (Dept of Mathematics and Statistics, Memorial University)17/06/2014, 09:15Theoretical Physics / Physique théorique (DTP-DPT)Invited Speaker / Conférencier invitéBlack holes are one of the most interesting theoretical predictions of general relativity. They arise as solutions to Einstein's equations which govern the classical gravitational field, generally described by a small number of parameters - mass, charge, and spin. A particular subset has recently attracted a great deal of attention: extremal black holes. For fixed mass, they are characterized...Go to contribution page

Mr Nils Deppe (University of Winnipeg)17/06/2014, 09:45Theoretical Physics / Physique théorique (DTP-DPT)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)String theory provides motivation to investigate critical phenomena in microscopic black hole formation in higher dimensional gravity theories. We investigate gravitational collapse in higher dimensional spherically symmetric Einstein and Einstein-Gauss-Bonnet (EGB) gravity. Our previous work has suggested the existence of a mass gap in odd dimensional EGB gravity. With adaptive mesh...Go to contribution page

Wilson Brenna (University of Waterloo)17/06/2014, 10:00Theoretical Physics / Physique théorique (DTP-DPT)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)The definition of a meaningful thermodynamic mass (appearing in the first law and the Smarr relation, when a cosmological constant is taken into account) is a difficult concept in Lifshitz symmetric spacetimes, due in part to the boundary conditions that need to be satisfied. Knowing such a mass opens up opportunities for examining the critical behaviour of these black holes which is...Go to contribution page

C. Danielle Leonard (University of Oxford)17/06/2014, 10:15Theoretical Physics / Physique théorique (DTP-DPT)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)At a time when understanding the accelerated expansion of the universe is one of the key questions of cosmology, we are compelled to examine the possibility of modifications to general relativity on very large scales. To do so, we consider the weak lensing power spectrum, for which deviations from the standard general relativistic form may be hallmarks of modified gravity. However, computing...Go to contribution page

Ms Allison Kolly (University of Winnipeg)17/06/2014, 10:30Theoretical Physics / Physique théorique (DTP-DPT)Oral (Student, In Competition) / Orale (Étudiant(e), inscrit à la compétition)An interesting property of anti-de Sitter space is that massless fields can travel to infinity in a finite time, bounce back more focussed and collapse to form a black hole. This has recently been shown to lead to the instability of AdS against the formation of black holes. Our goal is to shed light on this by numerically examining the effect of adding higher curvature terms to the...Go to contribution page
