ISIMA 2014 Conference: Gravitational Dynamics

CITA Toronto, June 30th - July 4th 2014.

The ISIMA conference is hosted in the first week of the ISIMA program, and features invited pedagogical lectures in the morning, with afternoon contributed talks presenting state-of-the-art research on the program topic. Participation to the ISIMA conference is open to everyone who wishes to attend.

The morning lectures are video-recorded, and meant for a broad audience. The afternoon talks are typically 20-25 minutes long each, and present the latest developments in the field. All presentations are published online, please click on the link to access them.

More detail about the upcoming conference will be posted as the organization of the program proceeds.

Florent Renaud: Galactic tides on star clusters: rocking the cradle and nailing the coffin.

Abstract: Coupling between scales occurs through a wide diversity of physical processes like turbulence, magnetic fields, feedback. Among them, gravity and its differential form, the tidal field, are present at all scales. The tidal field of interacting galaxies appears to be compressive over large volumes and coincide with the properties of the starburst activity. I propose a new theory to explain the enhancement of star formation in extended volumes, involving compressive tides and the cascade of this energy down to small scales via compressive turbulence. Using hydrodynamical simulations, I found a strong correlation between the tidal trigger and the starburst, leading to the formation of massive star clusters, probably the progenitors of globular clusters. When formed in the early Universe, at least a fraction of these clusters need to survive the galactic interactions to be detected at present day. Using the direct code Nbody6tt, based on Aarseth's Nbody6, we follow the evolution of a population of star clusters in a merger and note that the galactic collisions have no direct impact on the dissolution of clusters. By changing their orbit however, they leave an imprint on the long term evolution of these stellar objects.
