cds-question@unistra.frinterstellar-mediumco-line-emissionUsing the Purple Mountain Observatory Delingha 13.7m telescope, we conducted a large-scale ^12^CO(J=1->0) outflow survey (over ~110deg^2^) toward the W3/4/5 complex and its surroundings. In total, 459 outflow candidates were identified. Approximately 62% (284) were located in the Perseus arm, including the W3/4/5 complex and its surroundings, while ~35% (162) were located in the Local arm, ~1% (5) were in the Outer arm, and ~2% (8) were in two interarm regions. This result indicated that star formation was concentrated in the Galactic spiral arms. The detailed spatial distribution of the outflow candidates showed that the Perseus arm presented the most active star formation among the study regions. The W3/4/5 complex is a great region to research massive star formation in a triggered environment. A key region, which has been well studied by other researches, is in the eastern high-density W3 complex that neighbors the W4 complex. Two shell-like structures in the Local arm contain candidates that can be used to study the impact on star formation imposed by massive or intermediate-mass stars in relatively isolated systems. The majority of outflow candidates in the two interarm regions and the Outer arm are located in filamentary structures.2019ApJS..242...19Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/242/19CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/64 : Westerhout's Catalogue of 82 Discrete Sources (Westerhout 1958)III/182 : HDE Charts: positions, proper motions (Nesterov+ 1995)I/254 : The HST Guide Star Catalog, Version 1.2 (Lasker+ 1996)I/259 : The Tycho-2 Catalogue (Hog+ 2000)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)V/125 : Photometry and Spectroscopy for Luminous Stars (Reed 2005)II/311 : WISE All-Sky Data Release (Cutri+ 2012)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)J/A+A/426/503 : High velocity molecular outflows catalog (Update) (Wu+ 2004)J/AJ/129/393 : UBV photometry in W3 (Oey+, 2005)J/ApJ/653/1226 : Physical properties of galactic HII regions (Quireza+, 2006)J/ApJ/668/331 : OH masers in W3(OH) (Fish+, 2007)J/A+A/472/187 : 12CO outflows towards submm cores in Perseus (Hatchell+, 2007)J/ApJ/688/1142 : Star formation in W5: Spitzer observations (Koenig+, 2008)J/MNRAS/415/1202 : BVI photometry in W5E HII region (Chauhan+, 2011)J/MNRAS/418/2121 : CO 3-2 observations of outflows in W5 (Ginsburg+, 2011)J/ApJ/743/39 : Spitzer obs. of W3 molecular cloud (Rivera-Ingraham+, 2011)J/ApJ/733/113 : IRAC observations of IC 1795 (Roccatagliata+, 2011)J/A+A/558/A53 : MW global survey of star clusters.
