PublicationThe Radial Distribution of Mono-metallicity Populations in the Galactic Disk as Evidence for Two-phase Disk Formation
Recent determinations of the radial distributions of mono-metallicity populations (MMPs, i.e., stars in narrow bins in [Fe/H] within wider [α/Fe] ranges) by the...

PublicationThe Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies
We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER)...

PublicationThe Realm of the Galactic Globular Clusters and the Mass of Their Primordial Clouds
By adopting the empirical constraints related to the estimates of helium enhancement ({{Δ }}Y), the present mass ratio between first and second stellar...

PublicationThe Recent Stellar Archeology of M31—The Nearest Red Disk Galaxy
We examine the star-forming history of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main-sequence stars at distances R GC >...

PublicationThe Redshift Distribution of Flat-Spectrum Radio Sources
The redshift distribution of flat-spectrum radio sources with 5 GHz flux densities S5>~5 mJy is a key component in using current radio lens surveys to probe the...

PublicationThe Remarkable Alternating Spectra of the Of?p Star HD 191612
The spectrum of HD 191612 has been found to display large, recurrent variations between two highly reproducible, peculiar states; at least four transformations...

PublicationThe Resolved Stellar Populations of a Dwarf Spheroidal Galaxy in the Virgo Cluster
We report on the discovery of a faint (MV~-10.6+/-0.2) dwarf spheroidal galaxy on deep F606W and F814W Hubble Space Telescope images of a Virgo intracluster...

PublicationThe Resolved Structure and Dynamics of an Isolated Dwarf Galaxy: A VLT and Keck Spectroscopic Survey of WLM
We present spectroscopic data for 180 red giant branch (RGB) stars in the isolated dwarf irregular galaxy Wolf-Lundmark-Mellote (WLM). Observations of the...
