New Radial Abundance Gradients for NGC 628 and NGC 2403
Danielle A. Berg, Evan D. Skillman, Donald R. Garnett +5
Motived by recent ISM studies, we present high quality MMT and Gemini spectroscopic observations of H II regions in the nearby spiral galaxies NGC 628 and NGC 2403 in order to meas…
Newly Identified Star Clusters in M33. III. Structural Parameters
Izaskun San Roman, Ata Sarajedini, Jon A. Holtzman +1
We present the morphological properties of 161 star clusters in M33 using the Advanced Camera For Surveys Wide Field Channel onboard the Hubble Space Telescope using observations w…
Newly Identified Star Clusters in M33. II. Radial HST/ACS Fields
Izaskun San Roman, Ata Sarajedini, Donald R. Garnett +1
We present integrated photometry and color-magnitude diagrams for 161 star clusters in M33, of which 115 were previously uncataloged, using the Advanced Camera For Surveys Wide Fie…
Neon and Oxygen Abundances in M33
N. R. Crockett, D. R. Garnett, P. Massey +1
We present new spectroscopic observations of 13 H II regions in the Local Group spiral galaxy M33. The regions observed range from 1 to 7 kpc in distance from the nucleus. Of the 1…
Recombination Line vs. Forbidden Line Abundances in Planetary Nebulae
Mark Robertson-Tessi, Donald R. Garnett
Recombination lines (RLs) of C II, N II, and O II in planetary nebulae (PNs) have been found to give abundances that are much larger in some cases than abundances from collisionall…
Abundances of metal-rich H II regions in M51
Fabio Bresolin, Donald R. Garnett, Robert C. Kennicutt
We have obtained multi-object spectroscopy of H II regions in the spiral galaxy M51 with the Keck I telescope and the Low Resolution Imaging Spectrometer. For 10 objects we have de…
