Description
Hot Topics in Theoretical Physics (DTP) – This year the DTP symposium will address on aspects of gravitational physics. In the first part we will focus on exciting advances in observation (electromagnetic, gravitational wave and processing ability) that have happened in the last decade and what theory is doing to address them. In the second we will we focus on the fundamental and perennial problem of quantum gravity.
Neutron stars are the densest known gravitationally-stable objects in the Universe. Their strong gravitational fields, rapid rotation rates, and supra-nuclear central densities allow for a fascinating interplay between general relativistic effects and nuclear physics theory. Pulse-profile modeling is a technique that uses the gravitationally-lensed X-ray flux emitted from hot spots on the...
From the smallest particles to the largest structures in the Universe, physics seeks to understand how matter interacts. At the heart of some of the most energetic environments in the cosmos, supermassive black holes shape galaxies across cosmic time through powerful jets and outflows—a process known as black hole feedback—which regulates the growth of galaxies and even entire galaxy...
Multi-messenger astronomy was revolutionized by the detections of gravitational waves (GW) from the binary neutron star (BNS) merger GW170817 and electromagnetic (EM) waves from the resultant kilonova explosion and short gamma ray burst. This single event confirmed the association of the latter two EM signals with BNS mergers, and the possibility of a kilonova remnant, analogous to a supernova...
Gravitational waves, first predicted by Einstein's theory of general relativity, have opened a new window for observing the universe. Detections of coalescing binaries made by gravitational-wave observatories rely on both accurate theoretical models and precise observational techniques, bridging theory and data together. This talk will review how theory has helped bring us into the era of...
