Vig, IIST Abstract Type : Poster Abstract Category : Stars,ISM and the Galaxy Abstract : We present low frequency radio continuum maps (GMRT: 610 and 1280 MHz) of two southern Galactic HII regions associated with IRAS 17009-4042 and IRAS 17008-4040, both located at a distance of ∼2.0 kpc from the solar system. In this presentation, we investigate the morphology of the ionized gas and study the radio properties of these regions. We also generate the spectral index map to understand the mechanism behind the observed emission. In addition, we have estimated the spectral types of the ionizing source and the dynamical ages of these HII regions. We have also probed the possible nature of the exciting source of the ionized nebulae by identifying the near and mid-infrared counterparts from the 2MASS and Spitzer-GLIMPSE catalogs. |
