    "The Neutral Islands during the Late Epoch of Reionization"

    Abstract:   The growth of isolated ionized regions during the early stage of reionization is well described by the “bubble model”. However, the basic assumption of isolated and spherical ionized bubbles...

    "The tide is turning in large scale structure"

    Abstract: Tidal effects have long been known to influence dark matter halo formation.  Tidal effects on halo clustering are more subtle, but they do matter for precision cosmology.   I'll describe recent work showing there is, in fact, a strong correlation between the tidal field and galaxy clustering strength in the SDSS.  However, most of this observed galaxy-tidal field correlation is inherited from that for the host halos:  how galaxies populate halos is determined primarily by halo mass than by tidal...

    “Old Galaxies, New Surprises”

    I will present new results from the ongoing Hyper Suprime Cam survey currently being carried out by Subaru. The HSC survey is an unprecedented effort to map 1400 deg^2 in 5 bands to i~26. This unique combination of depth and area enables us to study the individual light profiles of several thousand super massive galaxies (M*>11.6 Msun) to 100 kpc and beyond. We show that massive galaxies are not self similar and that instead their light profiles are diverse. This diversity is not random: using weak gravitational lensing we make a remarkable...
