Mapping the Star Formation in NGC 1097 Using the JVLA
Abstract
We present new C- and L-band VLA continuum observations of the prototypical, nearby barred spiral galaxy, NGC 1097. The circumnuclear ring is well-imaged and C-band continuum is also detected along the bar dust lanes and the bar end. The VLA data is combined with GALEX and Hα data to inventory the obscured and unobscured star formation activity within the ring, at the ends of the bar, and along the bar. We estimate the synchrotron and thermal contributions from the VLA data and compare the thermal star formation estimate to those measured from the Hα data. The observations are used to understand how star formation progresses in the circumnuclear ring, the bar and at the bar ends.
