The ability of the Space Surveillance Telescope (SST) to find small (2–15 m diameter) NEAs suitable for the NASA asteroid retrieval mission is investigated. Orbits from a simulated population of targetable small asteroids were propagated and observ

We derive the molecular properties for a sample of 301 Galactic HII regions including 123 ultra compact (UC), 105 compact, and 73 diffuse nebulae. We analyze all sources within the BU-FCRAO Galactic Ring Survey (GRS) of 13CO emission known to be HII

Operation of a CCD imager on a curved focal surface offers advantages to flat focal planes, especially for lightweight, relatively simple optical systems. The first advantage is that the modulation transfer function can approach diffraction-limited p

Using 13CO J = 1 ? 0 molecular line emission from the Boston University-Five College Radio Astronomy Observatory Galactic Ring Survey (BU-FCRAO GRS), we have established kinematic distances to 313 infrared dark clouds (IRDCs) by matching the morpholo

We present infrared observations of the young, oxygen-rich supernova remnant 1E 0102.2-7219 (E0102) in the Small Magellanic Cloud, obtained with the Spitzer Space Telescope. The remnant is detected at 24 um but not at 8 or 70 um and has a filled morp

Examination of early, in-orbit checkout (IOC) images of a portion of the Galactic plane obtained by the Infrared Array Camera (IRAC) aboard the Spitzer Space Telescope revealed the presence of an extended emission nebula with internal structure. The

We have surveyed 12 Galactic hot molecular cores for interstellar acetic acid (CH3COOH). This is the most extensive search for acetic acid to date. We have detected a new source of acetic acid toward the high-mass hot molecular core source G34.3+0.2.

We present 12CO J = 1 → 0 maps of the extended envelope of IRC +10216 made by combining BIMA millimeter array and NRAO 12 m telescope observations. CO emission was detected beyond the radius of 140'', which traces the history of mass loss for the p

The Space Surveillance Telescope (SST) is a three-mirror Mersenne-Schmidt telescope with a 3.5 m primary mirror that is designed for deep, wide-area sky surveys. The SST design incorporates a camera with charge-coupled devices (CCDs) on a curved subs

Using the SEQUOIA multi-pixel array receiver on the Five College Radio Astronomy Observatory (FCRAO) 14 m telescope, we are conducting a new molecular line survey of the inner Galaxy. The Boston University (BU)-FCRAO Galactic Ring Survey (GRS) will m
