cds-question@unistra.fryoung-stellar-objectsstar-forming-regionsinfrared-photometryastronomical-object-identificationWe have conducted a study of star formation in the outer Galaxy from 65{deg}<l<265{deg} in the region observed by the GLIMPSE360 program. This Spitzer warm mission program mapped the plane of the outer Milky Way with IRAC at 3.6um and 4.5um. We combine the IRAC, Wide-field Infrared Survey Explorer (WISE), and Two Micron All Sky Survey catalogs and our previous results from another outer Galaxy survey and identify a total of 47,338 young stellar objects (YSOs) across the field spanning >180{deg} in Galactic longitude. Using the DBSCAN method on the combined catalog, we identify 618 clusters or aggregations of YSOs having five or more members. We identify 10,476 class I, 29,604 class II, and 7325 anemic class II/class III YSOs. The ratio of YSOs identified as members of clusters was 25,528/47,338, or 54%. We found that 100 of the clusters identified have previously measured distances in the WISE H II survey. We used these distances in our spectral energy distribution (SED) fitting of the YSOs in these clusters, of which 96 had YSOs with <3{sigma} fits. We used the derived masses from the SED model fits to estimate the initial mass function (IMF) in the inner and outer Galaxy clusters; dividing the clusters by galactocentric distances, the slopes were {Gamma}=1.87{pm}0.31 above 3M_{sun}_ for R_Gal_<11.5kpc and {Gamma}=1.15{pm}0.24 above 3M_{sun} for R_Gal_>11.5kpc. The slope of the combined IMF was found to be {Gamma}=1.92{pm}0.42 above 3M_{sun}_. These values are consistent with each other within the uncertainties and with literature values in the inner Galaxy high-mass star formation regions. The slopes are likely also consistent with a universal Salpeter IMF.2020AJ....160...68Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/160/68CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/mk : Catalogue of Stellar Spectral Classifications (Skiff, 2009- )II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/293 : GLIMPSE Source Catalog (I + II + 3D) (IPAC 2008)II/332 : c2d Spitzer final data release (DR4) (Evans+, 2003)II/311 : WISE All-Sky Data Release (Cutri+ 2012)II/314 : UKIDSS-DR8 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/319 : UKIDSS-DR9 LAS, GCS and DXS Surveys (Lawrence+ 2012)II/327 : AKARI Far-Infrared Surveyor YSO catalog (Toth+, 2014)II/328 : AllWISE Data Release (Cutri+ 2013)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)VII/233 : 2MASS All-Sky Extended Source Catalog (XSC) (IPAC/UMass, 2003-2006)J/AJ/131/1574 : Infrared photometry of IC348 members (Lada+, 2006)J/ApJ/669/493 : Spitzer/Chandra YSOs in Serpens cloud core (Winston+, 2007)J/ApJ/674/336 : Spitzer observations of NGC 1333 (Gutermuth+, 2008)J/ApJ/688/1142 : Star formation in W5: Spitzer observations (Koenig+, 2008)J/ApJS/184/18 : Spitzer survey of young stellar clusters (Gutermuth+, 2009)J/ApJS/193/25 : The NAN complex.
