A SINFONI view of the nuclear activity and circumnuclear star formation in NGC 4303 - II: Spatially resolved stellar populations

We present a spatially resolved stellar population study of the inner \(\sim\)200\,pc radius of NGC4303 based on near-infrared integral field spectroscopy with SINFONI/VLT at a spatial resolution of 40-80pc and using the STARLIGHT code. We found the distribution of the stellar populations presents a...

Zusammenfassung:	We present a spatially resolved stellar population study of the inner \(\sim\)200\,pc radius of NGC4303 based on near-infrared integral field spectroscopy with SINFONI/VLT at a spatial resolution of 40-80pc and using the STARLIGHT code. We found the distribution of the stellar populations presents a spatial variation, suggesting an age stratification. Three main structures stand out. Two nuclear blobs, one composed by young stars (t \(\leq\) 50Myr) and one with intermediate-age stars (50Myr \(
