Recent far-UV (FUV) and near-UV (NUV) observations of the nearby galaxy NGC 4625 made by the Galaxy Evolution Explorer (GALEX) show the presence of an extended UV disk reaching to 4 times the optical radius of the galaxy. The UV-to-optical colors suggest that the bulk of the stars in the disk of NGC 4625 are currently being formed, providing a unique opportunity to study today the physics of star formation under conditions similar to those when the normal disks of spiral galaxies like the Milky…

THE EVOLUTION OF STELLAR POPULATIONS IN THE OUTER DISKS OF SPIRAL GALAXIES
We investigate recent star formation in the extended ultraviolet (XUV) disks of five nearby galaxies (NGC 0628, NGC 2090, NGC 2841, NGC 3621, and NGC 5055) using a long wavelength baseline comprised
STAR CLUSTER POPULATIONS IN THE OUTER DISKS OF NEARBY GALAXIES
We present a Large Binocular Telescope imaging study that characterizes the star cluster component of nearby galaxy outer disks (beyond the optical radius R25). Expanding on the pilot project of
A PILOT STUDY USING DEEP INFRARED IMAGING TO CONSTRAIN THE STAR FORMATION HISTORY OF THE XUV STELLAR POPULATIONS IN NGC 4625
In a ΛCDM universe, disk galaxies' outer regions are the last to form. Characterizing their contents is critical for understanding the ongoing process of disk formation, but observing outer disk
The GALEX View of Ongoing Disk Formation in the Local Volume
We summarize the results of a search for extended ultraviolet disk (XUV-disk) galaxies in a sample of 189 nearby S0-Sm targets observed by GALEX, following the discovery of outer disk star formation
Spitzer Observations of Star Formation in the Extreme Outer Disk of M83 (NGC5236)
Spitzer Infrared Array Camera (IRAC) observations of two fields in the extended UV disk (XUV-disk) of M83 have been recently obtained, ∼3 RHII away from the center of the galaxy (RHII = 6.6 kpc).
On the nature of star formation at large galactic radii
We have compared far-ultraviolet (FUV), near-ultraviolet (NUV) and Hα measurements for star-forming regions in 21 galaxies, in order to characterize the properties of their discs at radii beyond the
Gas dynamics and star formation in the galaxy pair NGC 1512/1510
Here we present H i line and 20-cm radio continuum data of the nearby galaxy pair NGC 1512/1510 as obtained with the Australia Telescope Compact Array (ATCA). These are complemented by GALEX UV -,
The Red and Featureless Outer Disks of Nearby Spiral Galaxies
We present results from deep, wide-field surface photometry of three nearby (D = 4–7 Mpc) spiral galaxies: M94 (NGC 4736), M64 (NGC 4826), and M106 (NGC 4258). Our imaging reaches a limiting surface
A Search for Extended Ultraviolet Disk (XUV-Disk) Galaxies in the Local Universe
We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local universe. Here we compare GALEX UV and visible-NIR images of 189 nearby (D < 40 Mpc) S0-Sm galaxies included
ALMA CO(2-1) observations in the XUV disk of M83
The extended ultraviolet (XUV) disk galaxies are some of the most interesting objects studied in the last few years. The UV emission, revealed by GALEX, extends well beyond the optical disk after the
