A Galactic Origin for the Local Ionized X-ray Absorbers
Taotao Fang, Christopher McKee, Claude Canizares +1
Recent Chandra and XMM observations of distant quasars have shown strong local (z~0) X-ray absorption lines from highly ionized gas, primarily He-like oxygen. The nature of these X…
First astronomical detection of the CF+ ion
D. A. Neufeld, P. Schilke, K. M. Menten +7
We report the first astronomical detection of the CF+ (fluoromethylidynium) ion obtained by recent observations of its J = 1 - 0 (102.6 GHz), J = 2 - 1 (205.2 GHz), and J = 3 - 2 (…
Identification of Main Sequence Stars with Mid-Infrared Excesses Using GLIMPSE: Beta-Pictoris Analogs?
B. Uzpen, H. A. Kobulnicky, K. A. G. Olsen +23
Spitzer IRAC 3.6-8 micron photometry obtained as part of the GLIMPSE survey has revealed mid-infrared excesses for 33 field stars with known spectral types in a 1.2 sq. degree fiel…
G313.3+00.3: A New Planetary Nebula discovered by the Australia Telescope Compact Array and the Spitzer Space Telescope
Martin Cohen, Anne J. Green, Mallory S. E. Roberts +9
We present a new planetary nebula, first identified in images from the Australia Telescope Compact Array, although not recognized at that time. Recent observations with the Spitzer…
