The physical properties of the dust in the RCW 120 H II region as seen by Herschel
Context. RCW 120 is a well-studied, nearby Galactic H ii region with ongoing star formation in its surroundings. Previous work has shown that it displays a bubble morphology at mid-infrared wavelengths, and has a massive layer of collected neutral material seen at sub-mm wavelengths. Given the well-defined photo-dissociation region (PDR) boundary and collected layer, it is an excellent laborato...
متن کاملThe Ionizing Stars of the Galactic Ultra – Compact H II Region G 45 . 45 + 0 . 06
Using the NIFS near–infrared integral–field spectrograph behind the facility adaptive optics module, ALTAIR, on Gemini North, we have identified several massive O–type stars that are responsible for the ionization of the Galactic Ultra– Compact H II region G45.45+0.06. The sources “m” and “n” from the imaging study of Feldt et al. (1998) are classified as hot, massive O–type stars based on thei...
متن کاملThe extended narrow line region in Mkn 79 II . Modelling
We present photoionization modelling of the Extended Narrow Line Region (ENLR) in Mkn 79 based on long-slit spectra presented in our previous paper (Nazarova et al. 1996). The ENLR has been modelled with two gas components: a system of high density clouds embedded in a low density gas envelope. The ENLR line fluxes have been calculated allowing for attenuation of the nuclear ionizing continuum ...
متن کاملThe Molecular Properties of Galactic H Ii Regions
We derive the molecular properties for a sample of 301 Galactic H ii regions including 123 ultra compact (UC), 105 compact, and 73 diffuse nebulae. We analyze all sources within the BU-FCRAO Galactic Ring Survey (GRS) of CO emission known to be H ii regions based upon the presence of radio continuum and cm-wavelength radio recombination line emission. Unlike all previous large area coverage CO ...
متن کاملResolution of the Distance Ambiguity for Galactic H II Regions
We resolve the kinematic distance ambiguity for 266 inner Galaxy H ii regions out of a sample of 291 using existing H i and CO sky surveys. Our sample contains all H ii regions with measured radio recombination line (RRL) emission over the extent of the CO Boston University—Five College Radio Astronomy Observatory Galactic Ring Survey (18 < l < 55 and |b| < 1) and contains ultra compact, compac...
