Resumen:
We have found over 200 objects in the GLIMPSE survey that appear to be
outflows. These objects show excess emission in the [4.5] micron band
compared to the other IRAC bands ([3.6], [5.8], and [8.0]). They are
extended typically on scales of 10 arcseconds. We obtained molecular
hydrogen (2.122 micron) images with the WIYN Observatory on three of the
sources. The excess molecular hydrogen in each of the objects provides
further evidence that these are shocked outflows from young stellar
objects. We measured the [24] micron flux for each source available from
the MIPSGAL Survey. The [8.0]-[24] colors are generally greater than 5,
indicating that these are very young sources. In this poster we show
sample images of selected outflow regions from GLIMPSE, MIPSGAL and
WIYN, and discuss the energetics of the three sources with the ancillary
WIYN data.
