Starbursts Are Preferentially Interacting: Confirmation from the Nearest Galaxies
We complement a recent Letter by Luo et al. by comparing the fraction of starburst galaxies that are interacting with the overall fraction of interacting...
Dwarf galaxies offer an opportunity to understand the properties of low metallicity star formation both today and at the earliest times at the epoch of the...
Statistical properties of H II regions in the disc of M100
From a new mosaic image in the Hα line of the complete disc of the spiral galaxy M100, a catalogue is composed listing 1948 individual H II regions. I give...
Statistical Properties of Highly Luminous HII Regions in the Interacting Zone of the Antennae Galaxies, and Comparison with the Molecular Cloud Component
We have used the package CLOUDPROPS (Rosolowsky & Leroy 2008) in order to identify clouds, which are contained in data cubes of molecular/Hα line emission, and...
Statistical redshift of the very-high-energy blazar S5 0716+714
Context. Blazars are the most numerous class of very-high-energy (VHE; E > 100 GeV) gamma-ray emitters. At present, measured redshifts are available only for...
Statistical studies of HII regions in nearby galaxies. I. Spitzer near-IR luminosities and temperatures, compared with Hα luminosities, from selected HII regions in M100
Aims: We systematically study the relations between the Hα luminosity and the near-IR luminosity and temperature of a set of selected HII regions in the disc of...
In this contribution we evaluate the minimal cluster mass for which the effects of an incomplete sampling of the Initial Mass Function (IMF) cannot be neglected...
