We present the first study of GALEX far-ultraviolet (FUV) luminosity functions of individual star-forming regions within a sample of 258 nearby galaxies spanning a large range in total stellar mass and star formation properties. We identify ∼65 000 star-forming regions (i.e. FUV sources), measure each galaxy's luminosity function, and characterize the relationships between the luminosity function slope (α) and several global galaxy properties. A final sample of 82 galaxies with reliable… 
Star-forming Clumps in Local Luminous Infrared Galaxies
We present HST narrowband near-infrared imaging of Paα and Paβ emission of 48 local luminous infrared galaxies (LIRGs) from the Great Observatories All-Sky LIRG Survey. These data allow us to measure
Star-forming clumps in the Lyman Alpha Reference Sample of galaxies – I. Photometric analysis and clumpiness
We study young star-forming clumps on physical scales of 10–500 pc in the Lyman-Alpha Reference Sample (LARS), a collection of low-redshift (z = 0.03–0.2) UV-selected star-forming galaxies. In each
The Hierarchical Distribution of the Young Stellar Clusters in Six Local Star-forming Galaxies
We present a study of the hierarchical clustering of the young stellar clusters in six local (3–15 Mpc) star-forming galaxies using Hubble Space Telescope broadband WFC3/UVIS UV and optical images
Young star cluster populations in the E-MOSAICS simulations
We present an analysis of young star clusters (YSCs) that form in the E-MOSAICS cosmological, hydrodynamical simulations of galaxies and their star cluster populations. Through comparisons with
Star cluster catalogues for the LEGUS dwarf galaxies
We present the star cluster catalogues for 17 dwarf and irregular galaxies in the HST Treasury Program ‘Legacy ExtraGalactic UV Survey’ (LEGUS). Cluster identification and photometry in this
Extreme magnification of an individual star at redshift 1.5 by a galaxy-cluster lens
Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z = 1.49 (dubbed MACS J1149 Lensed Star
Massive Star Cluster Formation and Destruction in Luminous Infrared Galaxies in GOALS. II. An ACS/WFC3 Survey of Nearby LIRGs
We present the results of a Hubble Space Telescope WFC3 near-UV and Advanced Camera for Surveys Wide Field Channel optical study into the star cluster populations of a sample of 10 luminous infrared
Young massive clusters in the interacting LIRG Arp 299: evidence for the dependence of star cluster formation and evolution on environment
Archival WFC3/UVIS imaging of Arp 299 (NGC 3690E + NGC 3690W) is retrieved to investigate the young massive cluster (YMC) population of this ongoing merger. We extract 2182 cluster candidates,


A composite HII region luminosity function in H alpha of unprecedented statistical weight
Context. Statistical properties of HII region populations in disk galaxies yield important clues to the physics of massive star formation. Aims. We present a set of HII region catalogues and
The Luminosity Functions and Size Distributions of H II Regions in Irregular Galaxies
CCD Hα images were used to study the properties of H II regions in 29 normal Im galaxies and six blue compact dwarf/starburst irregulars. The Hα emission line fluxes were measured and used to
We study the relationship between the field star formation and cluster formation properties in a large sample of nearby dwarf galaxies. We use optical data from the Hubble Space Telescope and from
The Star Formation Efficiency in Nearby Galaxies: Measuring Where Gas Forms Stars Effectively
We measure the star formation efficiency (SFE), the star formation rate (SFR) per unit of gas, in 23 nearby galaxies and compare it with expectations from proposed star formation laws and thresholds.
Star-forming Complexes in a Sample of Spiral and Irregular Galaxies
Over 300 star-forming complexes in 11 intermediate- and late-type spiral and irregular galaxies have been observed in the B, I, and Hα bands to determine their luminosity functions, ages, sizes, and
The Dust Opacity of Star‐forming Galaxies
The presence of dust in galaxies removes one‐half or more of the stellar energy from the UV‐optical budget of the universe and has a profound impact on our understanding of how galaxies evolve.
Hierarchical star formation across the ring galaxy NGC 6503
We present a detailed clustering analysis of the young stellar population across the starforming ring galaxy NGC 6503, based on the deep HST photometry obtained with the Legacy ExtraGalactic UV
A galex ultraviolet imaging survey of galaxies in the local volume
We present results from a GALEX ultraviolet (UV) survey of a complete sample of 390 galaxies within ∼11 Mpc of the Milky Way. The UV data are a key component of the composite Local Volume Legacy, an
Probing the role of the galactic environment in the formation of stellar clusters, using M83 as a test bench
We present a study of the M83 cluster population, covering the disc of the galaxy between radii of 0.45 and 4.5 kpc. We aim to probe the properties of the cluster population as a function of distance
The K-band luminosity functions of super star clusters in luminous infrared galaxies, their slopes and the effects of blending
Super star clusters (SSCs) are typically found in interacting galaxies and trace an extreme form of star-formation. We present a K-band study of SSC candidates in a sample of local luminous infrared
