cds-question@unistra.frgalaxiesvisible-astronomyh-alpha-photometryextinctionThe production rate of ionizing photons in young (<=8Myr), unresolved stellar clusters in the nearby irregular galaxy NGC 4214 is probed using multi-wavelength Hubble Space Telescope WFC3 data. We normalize the ionizing photon rate by the cluster mass to investigate the upper end of the stellar initial mass function (IMF). We have found that within the uncertainties the upper end of the stellar IMF appears to be universal in this galaxy, and that deviations from a universal IMF can be attributed to stochastic sampling of stars in clusters with masses {<~}10^3^M_{sun}_. Furthermore, we have found that there does not seem to be a dependence of the maximum stellar mass on the cluster mass. We have also found that for massive clusters, feedback may cause an underrepresentation in H{alpha} luminosities, which needs to be taken into account when conducting this type of analysis.2013ApJ...767...51Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/767/51CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/549/A70 : NGC 4214 multiband images (Hermelo+, 2013)J/ApJ/755/40 : HII regions in the Magellanic clouds (Pellegrini+, 2012)J/ApJ/744/44 : H{alpha} and UV fluxes in nearby galaxies (Weisz+, 2012)J/ApJS/192/6 : A GALEX UV imaging survey of nearby galaxies (Lee+, 2011)J/ApJ/706/599 : H{alpha} and UV SFR in the local volume (Lee+, 2009)J/ApJS/178/247 : H{alpha} and [NII] survey in local 11 Mpc (Kennicutt+, 2008)J/AJ/133/917 : HST photometry of two NGC 4214 clusters (Ubeda+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/767/51https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/767/51http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/767/51https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/767/51https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/767/51http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/767/51GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/767/51/table1 (Ages, masses, and extinctions of clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/767/51/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/767/51/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/767/51/table1?GETtext/xml+votable180.050000true183.9136583336.332205560.0055555555555555566/28631https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/767/51?format=asciiOpticaldefaultJ/ApJ/767/51/table1Ages, masses, and extinctions of clustersrecnoRecord number assigned by the VizieR team.
