Astrophysics activities at Georgia Tech are devoted to interdisciplinary research and education linking astrophysics, astroparticle physics, cosmology, numerical relativity and gravitational wave physics. Research focuses on extreme astrophysics such as mergers of black holes and neutron stars, central engines of active galactic nuclei, gamma ray bursts and the sources of the highest energy neutrinos. Faculty that conduct astrophysics research at Georgia Tech form the Center for Relativistic Astrophysics (CRA).

  • Astroparticle Physics: Georgia Tech's efforts in subatomic physics are in the area of experimental astroparticle physics. Astroparticle physics studies the most powerful objects in the Universe, such as pulsars, gamma ray bursts, supermassive black holes at the center of galaxies a supernovas. Important questions that astroparticle physics helps to answer include the origin of cosmic rays, the acceleration of high-energy particles in astrophysical objects, tests of fundamental physics, the origin of dark matter, neutrino properties, etc. Our faculty, postdocs and students collaborate in several large experiments to detect high-energy gamma rays and neutrinos, with activities ranging from data analysis to instrumentation. For more details, visit our website.
  • Black Holes and Neutron Stars: Black holes and neutron stars are the most compact objects in the universe, where matter is packed to very high densities under the relentless force of gravity. They are ideal tools to study gravity at its most extreme as well as a variety of physical processes that often accompany them, such as accretion of gas and energetic interactions with their environment. At the CRA, we currently investigate several key open questions in this area of research.
  • Computational Astrophysics: Dark matter, gravitational waves, black holes, neutron stars and neutrinos are just a few of the topics under consideration by the CRA faculty that require computational techniques.  Computers allow us to solve complicated, coupled non-linear equations, track high-energy particles through the sky, and reproduce the Universe inside our virtual lab.  The CRA  uses the NSF XSEDE resources, the CRA cluster, Cygnus, and our Visualization Lab to explore some of the secrets of the Universe.
  • Cosmology and Galaxy Evolution: The field of cosmology studies the universe in its entirety.  The evolution of galaxies and their central black holes are particularly useful to understand both the relevant cosmological and galactic processes that shape galaxies over billions of years.  The length scales involved in these processes can range from an atomic level, when studying atomic and molecular transitions that are important in star forming gas clouds, to the cosmological scale, where tidal forces from distant galaxies create the initial rotation of a galaxy.
  • Gravitational Physics: Gravity is one of the four fundamental interactions of nature.  Yet some of the most interesting predictions of the theory that governs gravitational interactions, General Relativity, allude direct detection.  Black Holes and Gravitational Waves are both results of General Relativity.
  • High-Energy Astrophysics: High-energy astrophysics is the study of fundamental physics within the most violent environments imaginable. X-ray and gamma-ray sources are used as laboratories to explore physical processes at temperatures, densities and energies so extreme that Earth-based experiments would be impossible. This type of research can therefore provide direct tests of many of the basic ideas of modern physics.

The beauty and complexity of the world around us owe a lot to the fact that the governing laws are nonlinear. This hidden commonality allows one to discover similarities in problems ranging from quantum phenomena at one end of the scale to the structure of the Universe at the other.  Georgia Tech nonlinear dynamics faculty work on a correspondingly wide range of problems, from quantum systems, the dynamics of fluids and granular media, optical and electronic systems, to problems lying at the interface between physics, chemistry, biology, and medicine.

The Physics of Living Systems Group in the School of Physics at Georgia Tech seeks to understand how physics can inform questions of structure, function and dynamics in biological systems, and to study fundamental physics questions posed by biological systems. Faculty associated with the group work on problems in a range of biological length and time scales: from evolution of planetary ecosystems over hundreds of millions of years to locomotion of 10 cm long lizards running on sand at 1 m/sec, to the mechanics of  ~20 micron diameter cells and their dynamics on second to minute time scales, to assembly of viruses within 100 msec to the study of how DNA packing influences transcriptional dynamics and activity at the molecular level.

The Soft Matter Group in the School of Physics at Georgia Tech is at the interface between colloidal physics, nano-science, granular materials and hydrodynamics. We combine experiments at different lenght scales and theory to explore a range of scientific and thechonoligcal relevant topics such as the intimate mechanisms of the dynamics of fluid interfaces from the macroscopic down to the molecular level, the physics of liquid crystal materials in curved spaces, soft particles in complex fuilds, and self-assembly under confinement. The Soft Matter Group at Georgia Tech has a strong focus in basic science, which is constantly coupled with technological challanges including the development of new instrumentation, and new nano- and micro-fabrication methods.
