Toronto Astrophysical Gas and Fluid Dynamics Group

The Astrophysical Gas Dynamics Group is an affiliation of members of CITA and the Dept. of Astronomy & Astrophysics at the University of Toronto. Discussions are geared toward, but not limited to, analytical and numerical techniques and their application in current research. Journal-club style and review talks are especially sought. 

One focus of the group is the use of the McKenzie Cluster (a 1.2 TFlops beowulf machine) and the development of codes that incorporate important astrophysical processes.

We typically meet on Thursdays in room 1318A (McLennan Labs) to discuss gas-dynamical phenomena in a variety of astrophysical settings.  Informal talks and discussions are encouraged, but formal talks are allowed.  Spring 2005: please participate in the hydro-ph journal club and article discussion (run by J. Dursi and J. Everett).

Order-of-Magnitude Astrophysics Series:  This is a recent addition in Fall 2004. These lectures discuss methods of estimation applied to particular fields of astrophysics, give several examples, and pose challenge problems to the audience.  Click here to to go the lectures. 
Handouts from the introductory lecture: my table of constants, and Purcell's 1981 cheat sheet.  Also see the on-line textbook draft by Goldreich, Mahajan & Phinney, and the list of problems tackled at Ohio State.
