A multiwavelength study of the Inner Milky Way

Sagittarius B1 and B2 giant starforming clouds near the Galactic Centre :

B1 B2 7micron with VLA contours

Overlaid on the LW5 false colour mosaic are contours from the VLA 90cm dataset.

Below is the same region with contours from SCUBA images at 450 and 850 microns (representing very cool dust/molecular cloud material). There are several areas with sub millimetre emission obscured at ISOGAL wavelengths - particularly evident is the dark cloud near the right-top corner of the images.

And the same with SCUBA 850 micron contours:
