cds-question@unistra.frinterstellar-mediumyoung-stellar-objectsinfrared-sourcessurveysWe have performed an unbiased, deep near-infrared survey toward the Aquila molecular cloud with a sky coverage of ~1deg^2^. We identified 45 molecular hydrogen emission-line objects (MHOs), of which only 11 were previously known. Using the Spitzer archival data, we also identified 802 young stellar objects (YSOs) in this region. Based on the morphology and the location of MHOs and YSO candidates, we associate 43 MHOs with 40 YSO candidates. The distribution of jet length shows an exponential decrease in the number of outflows with increasing length, and the molecular hydrogen outflows seem to be oriented randomly. Moreover, there is no obvious correlation between jet lengths, jet opening angles, or jet H_2_ 1-0 S(1) luminosities and the spectral indices of the possible driving sources in this region. We also suggest that molecular hydrogen outflows in the Aquila molecular cloud are rather weak sources of turbulence, unlikely to generate the observed velocity dispersion in the region of survey.2015ApJS..219...21Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/219/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/584/A91 : Catalog of dense cores in Aquila from Herschel (Konyves+, 2015)J/ApJ/802/59 : A search for YSO candidates in IRDC G53.2 (Kim+, 2015)J/ApJ/779/113 : IR photometry of YSOs in the W40 region (Mallick+, 2013)J/ApJS/207/5 : YSOs in LDN 1641 with Hectochelle spectra (Fang+, 2013)J/MNRAS/421/3257 : MHO catalogue for Serpens and Aquila (Ioannidis+, 2012)J/PASJ/63/S1 : Atlas & catalog of dark clouds based on 2MASS (Dobashi+, 2011)J/AJ/140/1214 : Near-IR spectroscopic survey of class I YSOs (Connelley+, 2010)J/A+A/511/A24 : MHO Catalogue (Davis+, 2010)J/ApJS/184/18 : Spitzer survey of young stellar clusters (Gutermuth+, 2009)J/A+A/496/153 : Molecular hydrogen flows along Ori A cloud (Davis+, 2009)J/AJ/136/2391 : GLIMPSE Extended Green Objects catalog (Cyganowski+, 2008)J/MNRAS/387/954 : H2 imaging of NGC 1333, L1455, L1448 and B1 (Davis+, 2008)J/ApJ/674/336 : Spitzer observations of NGC 1333 (Gutermuth+, 2008)J/AJ/133/1528 : IR nebulae around young stellar objects (Connelley+, 2007)J/A+A/426/503 : Catalog of high velocity molecular outflows (Update) (Wu+ 2004)J/A+A/426/171 : H_2_ flows in rho Ophiuchi A (Khanzadyan+, 2004)J/A+A/392/239 : IR survey of outflows in Orion A (Stanke+, 2002)http://www.herschel.fr/cea/gouldbelt/en/ : Gouls Belt survey Web pagehttp://astro.kent.ac.uk/~df/MHCat/ : Catalog of MHOs in outflowshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/219/21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/219/21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/219/21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/219/21https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/219/21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/219/21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/219/21/table1 (Molecular hydrogen outflows identified in Aquila)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/219/21/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/219/21/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/219/21/table1?GETtext/xml+votable180.050000true277.156667-1.5452780.005555555555555556Cone search capability for table J/ApJS/219/21/table2 (Molecular hydrogen emission-line object (MHO) features in Aquila)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/219/21/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/219/21/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/219/21/table2?GETtext/xml+votable180.050000true277.1725-1.5355560.0055555555555555566/30341 30343 30352 30354https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/219/21?format=asciiInfrareddefaultJ/ApJS/219/21/table1Molecular hydrogen outflows identified in AquilarecnoRecord number assigned by the VizieR team.
