Grant's interests are in radio-loud AGN, specifically the morphology and dynamics of nuclear dusty
disks in radio galaxies,
AGN/host galaxy connections, and radio-loud unification models. These can largely be framed
in the context of AGN feedback, an exciting and growing area of study.
Find out how AGN feedback might be responsible for warping one particular disk
here. A recent study into the
connections between the morphology of nuclear dust distributions and the structure of their
radio-loud elliptical hosts can be found here.
(From left to right) (a) Hubble Space Telescope
(HST, optical), Chandra X-Ray Observatory (CXO, X-ray), and Very Large
Array (VLA, radio) composite of the radio galaxy 3C 84, a canonical example
of feedback from a radio galaxy driving shocks and cavities into its
surrounding medium (in this case the massive Perseus cluster of
galaxies). (b) CXO and VLA composite of the radio galaxy 3C
75, famous for its binary black hole system and entangled
upper radio jets.
(c) X-ray, sub-mm, and optical composite of the massive nearby radio galaxy Centaurus A (CXO, APEX, ESO 2.2m).
