Study of star formation in RCW 106 using far-infrared observations

Study of star formation in RCW 106 using far infrared observations

High resolution far-infrared observations of a large area of the star forming complex RCW 106 obtained using the TIFR 1m balloon-borne telescope are presented. Intensity maps have been obtained simultaneously in two bands centred around 150 and 210 µm. Intensity maps have also been obtained at the four IRAS bands using HIRES processed IRAS data. From the 150 and 210 µm maps, reliable maps of du...

Exploring Star Formation in Galaxy Populations using the Far-Infrared - Radio Correlation

Observational study of sites of triggered star formation CO and mid-infrared observations

Context. Bright-rimmed clouds (BRCs) are isolated molecular clouds located on the edges of evolved HII regions. Star formation within these clouds may have been triggered through the propagation of photoionisation-induced shocks driven by the expansion of the HII region. Aims. The main focus of this paper is to investigate the current level of star formation within a sample of southern hemisphe...

Mid - infrared and far - ultraviolet observations of the star - forming ring of M 31 ?

We present mid–IR images of a 15′×15′ field in the south–west part of the Andromeda galaxy M 31 obtained with the ISOCAM camera (6′′ pixels) on board ISO. These broad–band images complement spectro–imaging observations of smaller fields (Cesarsky et al. 1998). We also present a 20′′ resolution far–UV image of a larger field at 200 nm obtained with the balloon–borne telescope FOCA 1000. These im...

Radio and Far-infrared Emission as Tracers of Star Formation and Agn in Nearby Cluster Galaxies

We have studied the radio and far-infrared (FIR) emission from 114 galaxies in the 7 nearest clusters (< 100 Mpc) with prominent X-ray emission to investigate the impact of the cluster environment on the star formation and AGN activity in the member galaxies. The X-ray selection criterion is adopted to focus on the most massive and dynamically relaxed clusters. A large majority of cluster galax...
