YSO jets in the Galactic Plane from UWISH2. IV. Jets and outflows in Cygnus-X. (2018)

Keywords : catalogs; ISM jets and outflows; stars: formation; stars: protostars; stars: winds, outflows; surveys

Abstract:We have performed an unbiased search for outflows from young stars in Cygnus-X using 42deg^2^ of data from the UKIRT Widefield Infrared Survey for H_2_ (UWISH2 Survey), to identify shock-excited near-IR H_2_ emission in the 1-0 S(1) 2.122{mu}m line. We uncovered 572 outflows, of which 465 are new discoveries, increasing the number of known objects by more than 430%. This large and unbiased sample allows us to statistically determine the typical properties of outflows from young stars. We found 261 bipolar outflows, and 16% of these are parsec scale. The typical bipolar outflow is 0.45pc in length and has gaps of 0.025-0.1pc between large knots. The median luminosity in the 1-0 S(1) line is 10^-3^L_{sun}_. The bipolar flows are typically ...(more)

We utilized data from the UKIRT Widefield Infrared Survey for H_2_ (UWISH2), specifically the extension toward the Cygnus-X region of the Galactic plane as described in Froebrich+, 2015, J/MNRAS/454/2586 Cygnus-X was observed between 2013 April 6 and December 11. The survey used the Wide Field Camera (WFCAM) to obtain images in the 1-0 S(1) narrowband filter at 2.122um ({Delta}{lambda}=0.021um), at the UK Infra-Red Telescope (UKIRT) in Hawaii.
