Chandra X-ray observation of Gum 31
Gum 31 is a prominent, but still rather poorly studied HII region around the stellar cluster NGC 3324 at the northwestern periphery of the Carina nebula complex. Our aim was to... -
Massive star-forming regions radio lines
We present Australia Telescope Compact Array (ATCA) observations of the H_2_O maser line and radio continuum at 18.0GHz and 22.8GHz toward a sample of 192 massive star-forming... -
Inner Galaxy HII regions
We report simultaneous H110{alpha} and H_2_CO line observations with the 25m radio telescope of Nanshan station toward 251 HII regions. We used the H110{alpha} line to establish... -
PN and HII regions in NGC6822
Images obtained with the CTIO 4-m telescope and the MOSAIC-2 wide field camera in [OIII] 5007 and Halpha on-band and off-band filters are analyzed to search for emission line... -
HII regions in NGC 628
Properties of HII region populations in spiral galaxies provide important information about the physics of star formation as well as regional turbulent motions in the... -
PN and HII regions of West and East of NGC 3109
Images obtained with the ESO VLT and FORS1 in [O III] 5007 on- and off-band, as well as r_Gunn filters, are analyzed to search for planetary nebula (PN) candidates. In the... -
Westerlund 2 JHKs photometry
Photometry for the stars detected with SOFI, NTT in J, H and Ks in the field containing the massive cluster Westerlund 2 (also know as RCW 49) associated with the HII region... -
HII regions in minor mergers of galaxies
We present the results of the B, V and I photometry of eleven southern minor mergers. The total apparent B magnitude, integrated B-V and V-I colours were measured. We built B,... -
Radio Recombination Lines of Southern HII Regions
We tabulate velocities and other parameters of hydrogen recombination lines near 5GHz (H109{alpha} and H110{alpha}) for 316 HII regions observed with the Parkes 64-m radio... -
Data cubes of observed species toward Messier 8
Messier 8 (M8) is one of the brightest HII regions in the sky. We collected an extensive dataset comprising multiple submillimeter spectral lines from neutral and ionized carbon... -
JHKs and GLIMPSE photometry of RCW 120
This study deals with the star formation triggered by HII regions. We wish to take advantage of the very simple morphology of RCW 120 - a perfect bubble - to understand the...
