Description
Linking galaxy morphology with spatially resolved angular momentum
How do galaxies evolve from the complex, merging systems of the early Universe to the familiar Hubble types we see today? Tidal torques of the cosmic web impart angular momentum, which is consequently a fundamental property in a galaxy's evolutionary history, affecting that galaxy's size, density and morphology. In this talk I will present my group's research into the relation between specific angular momentum and galaxy evolution from the peak of cosmic star formation to today, including the close connection between the internal spatial distribution of angular momentum and visual morphology.

Within general relativity, the standard cosmological model adopts many approximations for gravitational interactions and geometry. These approximations have served us well so far, but as our error bars grow smaller and smaller we need to know at exactly what point they fail.
