    On the extreme properties of massive galaxies at high redshifts
    Massive (&#8805 10 11 M⊙) galaxies at high redshift (z &#8805 1.5) remain mysterious objects. Their extremely small sizes (effective radii of 1-2 kpc) make them...

    Orbital Torus Imaging: Using Element Abundances to Map Orbits and Mass in the Milky Way
    Many approaches to galaxy dynamics assume that the gravitational potential is simple and the distribution function is time invariant. Under these assumptions...
