| Abstract |
We present FUV and optical photometry of star clusters and surrounding
diffuse light in the outer regions of NGC 1275, the brightest galaxy in
the Perseus Cluster. Observations were taken with the HST/ACS Wide Field
Channel and Solar Blind Channel. These spectacular star forming regions
extending over tens of kpc resemble those of the giant emission line
filaments which are most likely drawn out by rising radio bubbles. Why
these star clusters are forming at large projected distances from the
main optical body of the galaxy remains a mystery. Ages and masses of
the compact star clusters and associated diffuse regions have been found
using single stellar population (SSP) modeling of our optical and FUV
photometry. Several relevant timescales are compared in an attempt to
understand the physical mechanisms that led to this unusual mode of star
formation.
This research is based on observations obtained with the NASA/ESA Hubble
Space Telescope through program GO-11207 that also supplied partial
grant support. |
