内容記述 |
At z less than or equal to 0.1, 10% of massive elliptical galaxies exhibit a substantial excess of ultraviolet emission over what is expected from their old stellar populations (the ‘UVX’). We explore the source and radial distribution of UVX in 49 nearby E/S0- type galaxies by measuring their extended photometry in the UV to mid-IR with GALEX, SDSS and WISE. We find a 1magnitude separation of color between the inner and outer regions. Via careful modelling, we show that this color difference is most readily explained by an approximately 0.5 to 2 Gyr age difference. This is consistent with ‘inside-out’ formation: rapid star formation in the core at greater than 4 Gyr ago, and at least one later stage starburst event coinciding with z-1. |
