The four HII regions in the Sgr A East complex: A, B, C, and D, represent evidence of recent massive star formation in the central ten parsecs. Using Paschen-alpha images taken with HST and 8.4 GHz VL...
We suggest an empirical calibration for determination of oxygen and nitrogen abundances and electron temperature in Hii regions where the [Oii]3727+3729 line (R2) is not available. The calibration...
Using deep Subaru/FOCAS spectra of 34 Hii regions in both the inner and outer parts of the extended ultraviolet (XUV) disc galaxy NGC 4625 we have measured an abundance gradient out to almost 2.5 time...
A group of four compact HII regions associated with the well-known 50 km/s molecular cloud is the closest site of on-going star formation to the dynamical center of the Galaxy, at a projected distance...

Wind-Blown Bubbles and HII Regions around Massive Stars
From Ultracompact to Extended HII Regions:Cloud Gravity and Stellar Motion

Internal Variation of Electron Density in Galactic and Extragalactic HII Regions
We present a comparison between the Parkes radio surveys (Filipovi ´c et al. 1995) and Vacuum Ultra-Violet (VUV) surveys (Smith et al. 1987) of the Large Magellanic Clouds (LMC). We have found...
