cds-question@unistra.frgalaxiesinfrared-photometryvisible-astronomybroad-band-photometryWe have surveyed the complete extent of the disk of M33 --a gas-rich low-mass dwarf spiral galaxy in the Local Group. The B-, V-, and I-passband (the Johnson-Cousins system) CCD images (typical seeing ~0.8") were obtained with the Subaru Telescope equipped with the Suprime-Cam mosaic camera. The wide-field (~1.0{deg}x1.5{deg}) catalog of 803,095 (15<=V<=25) starlike objects, measured using the point-spread function and aperture photometry techniques, is presented. We determined the distance modulus of M33 using the tip of the red giant branch (I_TRGB_=20.64+/-0.02) as a reference point of (m-M)_0_=24.63+/-0.02_stat_+/-0.06_syst_ (843kpc). We found young (<~100Myr) stellar populations residing up to the deprojected radius of ~10kpc. The scale length of the young main-sequence (MS) star surface-number density in the range of radial distances from 7 to 9kpc is 0.53+/-0.03kpc. The youngest MS stars (<~15Myr) reside up to the radius of ~8kpc. This distribution of stellar populations may suggest an outside-in scenario of recent star formation in the disk of M33.2024ApJS..273...22Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/273/22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/371/1405 : Variables in M33 (Hartman+, 2006)J/AJ/131/2478 : M31 and M33 UBVRI photometry (Massey+, 2006)J/A+A/533/A91 : Deep VI imaging in outer regions of M33 (Grossi+, 2011)J/ApJS/214/19 : Suprime-Cam wide-field photometry of Leo A (Stonkute+, 2014)J/MNRAS/449/4048 : The H{alpha} rotation curve of M33 (Kam+, 2015)J/ApJ/868/55 : Structure of M31 halo.
