Abstract:
We present the extended source catalogue for the UKIRT Wide Field
Infrared Survey for H2 (UWISH2). The survey is unbiased along the
inner Galactic Plane from l∼357° to l∼65° and |b|≤1.5°
and covers 209deg2. A further 42.0 and 35.5deg2 of high dust
column density regions have been targeted in Cygnus and Auriga. We
have identified 33200 individual extended H2 features. They have
been classified to be associated with about 700 groups of jets and
outflows, 284 individual (candidate) planetary nebulae, 30 supernova
remnants and about 1300 photodissociation regions. We find a clear
decline of star formation activity (traced by H2 emission from jets
and photodissociation regions) with increasing distance from the
Galactic Centre. About 60 percent of the detected candidate planetary
nebulae have no known counterpart and 25 percent of all supernova
remnants have detectable H2 emission associated with them.
Description:
All data were acquired using the Wide Field Camera (WFCAM) on the
United Kingdom Infrared Telescope (UKIRT), Mauna Kea, Hawaii. WFCAM
houses four Rockwell Hawaii-II (HgCdTe 2048x2048-pixel) arrays
spaced by 94 per cent in the focal plane. The pixel scale measures
0.4-arcsec, although microstepping is used to generate reduced mosaics
with a 0.2-arcsec pixel scale and thereby fully sample the expected
seeing.
