The Shark semi-analytic model: understanding the connection between galaxies and halos

We have recently introduced a new, highly flexible, open source semi-analytic model of galaxy formation, Shark. This model has the unique feature of having a large range of models for several of the key physical processes in galaxy formation (e.g. star formation, stellar feedback, gas cooling, AGN feedback, among others), allowing for a unique exploration of how our assumptions impact on the predicted galaxy population. In this talk I will introduce Shark and showcase its power by discussing two applications related to the kinematic coupling of galaxies and their halos: (i) how the angular momentum of galaxies decouples from that of their halo as a result of feedback and angular momentum transfer between the interstellar medium and stars; and (ii) how do we reconcile LCDM with the observed HI velocity function of galaxies.

Unless announced otherwise, the lunch talks start at 12:50 sharp. The approximate duration of the lunch talk is given above, and additional time will be given for questions and discussion following the presentation. Please make sure that you take ample time to pick up your lunch beforehand.

Information for Speakers and Hosts: Talks are limited to 25 minutes, with 5 additional minutes for questions. Hosts are responsible for bringing the speaker to the correct room in ample time to set up laptops etc., and for ensuring the speaker also has time for lunch.
