What can we learn about the kinematics of bright extragalactic planetary nebulae
M. G. Richer, S. -H. Baez, J. A. Lopez +2
We present high resolution spectroscopy in the [\ion{O}{3}]5007 and H lines of bright planetary nebulae in the Milky Way bulge and the dwarf galaxies M32, Fornax, Sagittarius…
The Synoptic All-Sky Infrared (SASIR) Survey
Joshua S. Bloom, J. Xavier Prochaska, William Lee +42
We are proposing to conduct a multicolor, synoptic infrared (IR) imaging survey of the Northern sky with a new, dedicated 6.5-meter telescope at San Pedro Mártir (SPM) Observatory.…
Recycling Matter in the Universe. X-ray observations of SBS 1150+599A (PN G135.9+55.9)
Gagik Tovmassian, John Tomsick, Ralf Napiwotzki +4
We present X-ray observations of the close binary nucleus of the planetary nebula SBS 1150+599A obtained with the XMM-Newton satellite. Only one component of the binary can be obse…
Chemical Properties of Star Forming Dwarf Galaxies
O. Vaduvescu, M. L. McCall, M. G. Richer
Recent studies of the near-infrared (NIR) properties of dwarf irregular galaxies (dIs) and blue compact dwarfs (BCDs) have provided improved estimates for the NIR luminosity of old…
The Progenitors of Planetary Nebulae in Dwarf Irregular Galaxies
Michael G. Richer, Marshall L. McCall
We present chemical abundances for planetary nebulae and H II regions in the Local Group dwarf irregular galaxy NGC 6822 based upon spectroscopy obtained at the Canada-France-Hawai…
