We construct the MZR for massive galaxies at z~0.7.
Optimized photo-z’s for all five CANDELS fields.
We develop a data-driven method for determining K-corrections for low redshift galaxies.
We use a deep capsule network to achieve state-of-the-art photo-z’s for SDSS galaxies.
We present a method for local calibration of PDFs with applications for photo-z’s.
We use Gaussian Process Regression trained on the fluxes of external galaxies to estimate the Milky Way’s UV-to-IR SED.
We introduce a method for local calibration of photo-z PDFs.
We develop a data access, exploration, analysis, and visualization toolkit for the SDSS-IV MaNGA survey that seamlessly transitions between locally and remotely-stored data.
We construct an analytic chemical evolution model with a realistic SNIa delay time distribution to probe how model parameters affect equilibrium abundances and the effects of sudden changes to those parameters.
We explore the trade-offs in parameters of chemical evolution models.
We use direct method metallicities of stacked SDSS galaxies to recalibrate strong line metallicity diagnostics.
The direct method mass-metallicity relation has a steeper slope, a lower turnover mass, and a factor of 2-3 greater dependence on SFR than strong line mass-metallicity relations.
PCA of elemental abundances of bulge stars revealing that the first two components are (1) correlated alpha elements and (2) correlated Na and Ni—two elements that have metallicity-dependent core-collapse supernova yields.
Radiation pressure from the absorption and scattering of starlight by dust grains, which are hydrodynamically coupled to the gas, sets a hard upper limit to the luminosity of star-forming regions.
