Astrophysics Research Areas

In this research we investigate active galactic nuclei and the environment immediately surrounding black holes. We use measurements from X-ray through to radio looking at the environment and dynamics of radio sources, unified models for both high-power and low-power objects, observation and modelling of jets and the X-ray/radio relationship in radio galaxies and quasars. We also study free floating black holes using advanced modelling to study the central potential well where the effects of gravity are important.

In this research we investigate galaxy populations and their evolution using surveys to look for preveiously undetected low surface brightness and compact galaxies, and observations of more distant clusters. We aim to measure the most accurate masses possible by combining observations of hot gas in X-ray using gravitational lensing effects of clusters and determining their galactic velocities.

In this research area we develop algorithms and methods for solving complex physics problems using state-of-the-art scientific computing resources. This research area is shared across multiple themes within the School such as Particle Physics and theoretical physics.

Observational Astrophysics employs the use of telescopes and instruments to examine and measure the principles of physics and chemistry in the study of astrophysical objects and phenomena. Here at Bristol we employ instruments that give us access to the whole electro magnetic spectrum to understand objects from distant galaxies, black holes, hydrogen continuum, planetary disk formation, exoplanet atmospheres, and our own solar system. We use state-of-the-art international telescopes from the ground and in space to make precise measurement of the universe around us.

In this research area we investigate everything from the earliest formation of planets via dynamic collisions, to the atmospheres and characteristics of solar system and exoplanets. Exoplanet science is incredibly diverse and the thousands of discovered exoplanets present a wide range of research qeustions to exople. Bristol specilises in the use of high performance computing to, simulate the collisional dynamics that help form, or destroy, planets; develop sophisticated multi-dimensional modelling of exoplanet atmospheres, their dynamics, and chemistry; and analyse observational measurements from state-of-the-art telescopes to examine and interpret the nature of planets of all sizes.

In this research area we study the production of chemical elements in stars. We also study how mass transfer from a binary companion can influence the composition of a star, leaving observational signatures long after the companion has faded away.
