An examination of the size of the narrow-line region for a large sample of active galaxies as a function of AGN luminosity is presented. We find that while there is a steep relationship between NLR size and AGN luminosity (as traced by IR photometry), there is a flattening of the relationship at the high luminosity end such that we may be seeing the physical extent of the NLR in luminous quasars.

The host galaxy stellar populations for 33 UV-selected z~2-3 AGNs, selected from the LBG survey, are discussed and analyzed. The host galaxies are massive, with high stellar ages and SFRs as compared to the non-active LBGs, although their properties are essentially identical when controlling for stellar mass, implying that the AGN is having little effect on galactic star-formation. An observed relationship between CIV line luminosity and host galaxy stellar mass can be understood as demonstrating that black hole mass and galactic mass are linked at z~2-3. (Hainline et al. 2012)
A Rest-frame UV composite spectrum was created and analyzed for the UV-selected AGNs. The composite spectrum is compared to a composite for non-AGNs from Shapley et al. 2003, and high velocity (~850 km/s) outflows are shown for highly-ionized gas. These results represent the first such comparison at high redshift between star-forming galaxies and similar galaxies that host AGN activity. (Hainline et al. 2011)
Rest-frame optical spectra are presented for three strongly-lensed star-forming galaxies, the Cosmic Horseshoe (z = 2.38), the Clone (z = 2.00), and SDSS J090122.37+181432.3 (z = 2.26). The magnification allows for a measurement of a full complement of high S/N rest-frame optical emission lines, which can be used to calculate metallicity and ionization state of the gas in these galaxies.

For my final four years of graduate school, I ran the UCLA Planetarium, which provided free weekly public planetarium shows, as well as free private shows for educational groups. I was also quite active with UCLA Astronomy Live!, the UCLA grad-student-run outreach organization. Each year, this group runs a fall outreach event, "Exploring Your Universe," providing the Los Angeles community a free day of exciting scientific workshops and programs.
