Ultracompact H Ii Regions
RESUMEN Discutimos algunos resultados observacionales recientes sobre regiones H II ultracompactas. En particular, discutimos la emisión extendida de algunas regiones H II UC y el descubrimiento de una nueva clase, denominada regiones H II " hipercompactas ". Además, describimos la obtención de la estructura de densidad usando la técnica del análisis deí ındice espectral. ABSTRACT We discuss so...
متن کاملThere’s Life in H Ii Regions Yet!
We give an overview of the literature on ionization front structure and propagation and comment on recombination front structures. We discuss the formation of cometary tails by photoionization of globules and note the importance of including the diffuse component of the ionizing radiation field. We finally briefly comment on the formation of small scale structures in H II regions.
متن کامل0 Radio Continuum and Recombination Line Study of UC H II Regions with Extended Envelopes
We have carried out 21 cm radio continuum observations of 16 UC HII regions using the VLA (D-array) in a search for associated extended emission. We have also observed H76α recombination line towards all the sources and He76α line at the positions with strong H76α line emission. The UC HII regions have simple morphologies and large (∼ >10) ratios of single-dish to VLA fluxes. We detected extend...
متن کاملNew Radio Catalog of Compact H II Regions in the Milky Way II . The 1 . 4 GHz Data
We utilize a new VLA Galactic plane catalog at 1.4 GHz covering the first and second Galactic quadrants (340 • ≤ l ≤ 120 • , |b| ≤ 0.8 • with |b| ≤ 1.8 • for 350 • ≤ l ≤ 40 • and |b| ≤ 2.5 • for 100 • ≤ l ≤ 105 •) in conjunction with the MSX6C Galactic plane mid-infrared catalog to supplement and better understand our 5 GHz catalog (Giveon et al. 2005). A radio catalog of this region was first ...
متن کاملDiscovery of Intergalactic H ii Regions
We have discovered a number of very small isolated H ii regions 20-30 kpc from their nearest galaxy. The H ii regions appear as tiny emission line dots (ELdots) in narrow band images obtained by the NOAO Survey for Ionization in Neutral Gas Galaxies (SINGG). We have spectroscopic confirmation of 5 isolated H ii regions in 3 systems. The Hα luminosities of the H ii regions are equivalent to the ...
