PublicaciónThe 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...

PublicaciónThe radio luminosity function from the low-frequency 3CRR, 6CE and 7CRS complete samples
We measure the radio luminosity function (RLF) of steep-spectrum radio sources using three redshift surveys of flux-limited samples selected at low (151 and...

PublicaciónThe 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)...

PublicaciónThe rates and modes of gas accretion on to galaxies and their gaseous haloes
We study the rate at which gas accretes on to galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a...

PublicaciónThe ratio of pattern speeds in double-barred galaxies
We have obtained two-dimensional velocity fields in the ionized gas of a set of eight double-barred galaxies, at high spatial and spectral resolution, using...

PublicaciónThe Recent Star Formation History of NGC 5102
We present Hubble Space Telescope photometry of young stars in NGC 5102, a nearby gas-rich post-starburst S0 galaxy with a bright young stellar nucleus. We use...

PublicaciónThe 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 >...
