抄録（英）
NGC 253 is well known local starburst galaxy which is currently undergoing a period of intense star formation. We present spatially resolved star-forming activity analysis of NGC 253 using multi-wavelength data from optical to radio. NGC 253 star-forming regions, especially those in the galactic center, are enshrouded by not a few amount of dust produced by their active star-formation. Star-formation tracers which suffer less dust extinction will be essential to investigate the star formation. Pa alpha emission line at 1.875 micrometers traces actual star-formation activity even at high extinction region that is difficult to measure it in optical wavelengths. We have carried out Pa narrow-band imaging observations which cannot be derived from ground based facilities except for TAO site. Low frequency (e.g. 1.4 GHz) radio continuum data taken with VLA and FIR forbidden lines with AKARI FIS/FTS and Herschel are also good tracers for current star-formation. Using above data and AKARI archive data the differences of star-formation activities among galactic center, bar, bar-end and inter-arm can be revealed.
