Project Lyman
Stephan R. McCandliss, Jeffrey W. Kruk, William P. Blair +20
We explore the design of a space mission, Project Lyman, which has the goal of quantifying the ionization history of the universe from the present epoch to a redshift of z ~ 3. Obs…
Detection of Extended Hot Water in the Outflow from NGC 2071
Gary J. Melnick, Volker Tolls, David A. Neufeld +5
We report the results of spectroscopic mapping observations carried out toward a ~1 min x 1 min region within the northern lobe of the outflow from NGC 2071 using the Infrared Spec…
Mapping warm molecular hydrogen with Spitzer's Infrared Array Camera (IRAC)
David Neufeld, Yuan Yuan
Photometric maps, obtained with Spitzer's Infrared Array Camera (IRAC), can provide a valuable probe of warm molecular hydrogen within the interstellar medium. IRAC maps of the sup…
SWAS Observations of Water in Molecular Outflows
J. Franklin, R. L. Snell, M. J. Kaufman +4
We present SWAS detections of the ground-state 1(10)-1(01) transition of o-H2O at 557 GHz in 18 molecular outflows. These results are combined with ground-based observations of the…
Detection of Acetylene toward Cepheus A East with Spitzer
P. Sonnentrucker, E. González-Alfonso, D. A. Neufeld
The first map of interstellar acetylene (C2H2) has been obtained with the infrared spectrograph onboard the Spitzer Space Telescope. A spectral line map of the vibration-rota…
Water vapor emission from IRC+10216 and other carbon-rich stars: model predictions and prospects for multitransition observations
Eduardo González-Alfonso, David A. Neufeld, Gary J. Melnick
We have modeled the emission of H2O rotational lines from the extreme C-rich star IRC+10216. Our treatment of the excitation of H2O emissions takes into account the excitation of H…
