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…
Spitzer IRAC observations of newly-discovered planetary nebulae from the Macquarie-AAO-Strasbourg H-alpha Planetary Nebula Project
Martin Cohen, Quentin A. Parker, Anne J. Green +10
We compare H-alpha, radio continuum, and Spitzer Space Telescope (SST) images of 58 planetary nebulae (PNe) recently discovered by the Macquarie-AAO-Strasbo- urg H-alpha PN Project…
No supernovae detected in two long-duration Gamma-Ray Bursts
D. Watson, J. P. U. Fynbo, C. C. Thöne +1
There is strong evidence that long duration gamma-ray bursts (GRBs) are produced during the collapse of a massive star. In the standard version of the Collapsar model, a broad-line…
The Frequency of Mid-Infrared Excess Sources in Galactic Surveys
B. Uzpen, H. A. Kobulnicky, A. J. Monson +27
We have identified 230 Tycho-2 Spectral Catalog stars that exhibit 8 micron mid-infrared extraphotospheric excesses in the MidCourse Space Experiment (MSX) and Spitzer Space Telesc…
Ly-alpha and UV emission from high-redshift GRB hosts: To what extent do GRBs trace star formation?
P. Jakobsson, G. Bjornsson, J. P. U. Fynbo +9
We report the result of a search for Ly-alpha emission from the host galaxies of the gamma-ray bursts (GRBs) 030226 (z = 1.986), 021004 (z = 2.335) and 020124 (z = 3.198). We find…
