Abstract:
Jets and outflows from young stellar objects (YSOs) are important
signposts of currently ongoing star formation. In order to study these
objects, we are conducting an unbiased survey along the Galactic plane
in the 1-0 S(1) emission line of molecular hydrogen at 2.122 um using
the United Kingdom Infrared Telescope. In this paper, we are focusing
on a 33-deg2-sized region in Serpens and Aquila (18°<l<30°;
-1.5°<b<+1.5°).
We trace 131 jets and outflows from YSOs, which results in a 15-fold
increase in the total number of known molecular hydrogen outflows.
Compared to this, the total integrated 1-0 S(1) flux of all objects
just about doubles, since the known objects occupy the bright end of
the flux distribution. Our completeness limit is 3x10-18W/m2 with
70 per cent of the objects having fluxes of less than 10-17W/m2.
Description:
We obtained our near-infrared (near-IR) narrow-band imaging data in
the 1-0 S(1) line of H2 using the Wide Field Camera at the United
Kingdom Infrared Telescope (UKIRT). Our data are part of the UWISH2
survey . Our narrow-band data were taken between 2009 July 31 and 2010
September 9.
Furthermore, we utilized the UK Infrared Deep Sky Survey (UKIDSS) data
in the near-IR JHK bands taken with the same telescope, same
instrumental setup and tiling as part of the Galactic Plane Survey
(Cat. II/316).

Note (1): * indicates that several MHOs belong to the same outflow.
Note (2): Only for objects with a source candidate, we determined the
apparent length and the position angle. Flow lengths are end-to-end
for bipolar outflows or source-to-end for single sided flows.
Note (3): Source names correspond to the catalogue entries the source was
taken from. These are either coordinate based, SIMBAD names, UKIDSS
GPS IDs (GPS NNNNN NNNNNNN, ID of II/316/gps6 Vizier table), or AKARI
IDs (AKARI NNNNNNN, objID of II/298/fis Vizier table). Sources
labelled 'Noname' are objects where it is assumed that there is a
driving source at the listed position, however, non of the catalogues
used shows a detection of the object.
