Massive Stellar Content of Giant H Ii Regions in M 33 and M 101 *
Far-ultraviolet (900-1200Å) spectral synthesis of nine giant extragalactic H II regions in M33 and M101 is performed to study their massive stellar content. Several parameters are quantified, predicted, and compared to the literature: age, stellar mass, IMF slope, number of O-type and Wolf-Rayet stars, Hα and 5500Å continuum fluxes. The results of this particular technique are consistent with o...
متن کاملPACS and SPIRE photometer maps of M 33: First results of the HERschel M 33 Extended Survey (HERM33ES)*
Context. Within the framework of the HERM33ES key program, we are studying the star forming interstellar medium in the nearby, metal-poor spiral galaxy M 33, exploiting the high resolution and sensitivity of Herschel. Aims. We use PACS and SPIRE maps at 100, 160, 250, 350, and 500 μm wavelength, to study the variation of the spectral energy distributions (SEDs) with galacto-centric distance. Me...
متن کاملFree-Free Spectral Energy Distributions of Hierarchically Clumped HII Regions
In an effort to understand unusual power-law spectral slopes observed in some hypercompact HII regions, we consider the radio continuum energy distribution from an ensemble of spherical clumps. An analytic expression for the free-free emission from a single spherical clump is derived. The radio continuum slope (with Fν ∝ ν ) is governed by the population of clump optical depths N(τ), such that ...
متن کامل100 μm and 160 μm emission as resolved star-formation rate estimators in M 33 (HERM33ES) *
Context. Over the past few years several studies have provided estimates of the SFR (star-formation rate) or the total infrared luminosity from just one infrared band. However these relations are generally derived for entire galaxies, which are known to contain a large scale diffuse emission that is not necessarily related to the latest star-formation episode. Aims. We provide new relations to ...
متن کاملUNDERSTANDING SPATIAL AND SPECTRAL MORPHOLOGIES OF ULTRACOMPACT H ii REGIONS
The spatial morphology, spectral characteristics, and time variability of ultracompact H ii regions provide strong constraints on the process of massive star formation. We have performed simulations of the gravitational collapse of rotating molecular cloud cores, including treatments of the propagation of ionizing and non-ionizing radiation. We here present synthetic radio continuum observation...
