A Catalog of Extended Green Objects (EGOs) in the GLIMPSE Survey: A new sample of massive young stellar object outflow candidates
C. J. Cyganowski, B. A. Whitney, E. Holden +12
Using images from the Spitzer GLIMPSE Legacy survey, we have identified more than 300 extended 4.5 micron sources (abbreviated EGO, Extended Green Object, for the common coding of…
Intrinsically Red Sources observed by Spitzer in the Galactic Mid-Plane
Thomas P. Robitaille, Marilyn R. Meade, Brian L. Babler +8
We present a highly reliable flux-limited census of 18,949 point sources in the Galactic mid-plane that have intrinsically red mid-infrared colors. These sources were selected from…
Smith's Cloud: A High-velocity Cloud Colliding with the Milky Way
Felix J. Lockman, Robert A. Benjamin, A. J. Heroux +1
New 21cm HI observations made with the Green Bank Telescope show that the high-velocity cloud known as Smith's Cloud has a striking cometary appearance and many indications of inte…
Infrared Spectroscopy of the Diffuse Ionized Halo of NGC 891
Richard J. Rand, Kenneth Wood, Robert A. Benjamin
We present infrared spectroscopy from the Spitzer Space Telescope at one disk position and two positions at a height of 1 kpc from the disk in the edge-on spiral NGC 891, with the…
Vertically Extended Neutral Gas in the Massive Edge-on Spiral NGC 5746
Richard J. Rand, Robert A. Benjamin
We present Very Large Array 21-cm observations of the massive edge-on spiral galaxy NGC 5746. This galaxy has recently been reported to have a luminous X-ray halo, which has been t…
The Milky Way's Kiloparsec Scale Wind: A Hybrid Cosmic-Ray and Thermally Driven Outflow
John E. Everett, Ellen G. Zweibel, Robert A. Benjamin +4
We apply a wind model, driven by combined cosmic-ray and thermal-gas pressure, to the Milky Way, and show that the observed Galactic diffuse soft X-ray emission can be better expla…
