Long Slit Spectroscopy of the Nearby Galaxy NGC 247
POSTER
Abstract
We present long slit spectroscopy of the nearby (3.3 Mpc) spiral galaxy NGC 247 from the Magellan I 6.5m Telescope. This galaxy is interesting because it is essentially bulgeless (type SAB(s)d) but with a nuclear star cluster. We measured steller kinematics and gas kinematics along a slit skewed 45 degrees off of the major axis and across the nuclear cluster. The spectral resolution (σ*=56 km s-1) is, unfortunately, not high enough to measure the small velocity dispersions accurately. We measure gas kinematics from the [OIII] and [Hβ] lines and see a velocity dispersion slightly higher than that of the stars. The central line emissionis resolved but is only 3.8" in extent. The central line emission is asymmetrically placed with respect to the star cluster.
