The stellar content of the WR galaxy NGC5253 from ISO/SWS spectroscopy (2007)
Paul A. Crowther, Sara C. Beck, Allan J. Willis, Peter S. Conti, Patrick W. Morris, Ralph S. Sutherland
1. Why mid-IR spectroscopy of WR galaxies? Wolf-Rayet (WR) galaxies are a subset of blue emission-line galaxies whose spectra show the signature of large numbers of WR stars with ages in the range
The Extraordinary Infrared Spectrum of NGC 1222 (Mkn 603) (2007)
Beck, Sara C., Turner, Jean L., Kloosterman, Jenna
The infrared spectra of starburst galaxies are dominated by the low-excitation lines of [NeII] and [SIII], and the stellar populations deduced from these spectra appear to lack stars larger than...
Brackett Lines from the Super Star Cluster Nebulae in He 2-10 (2006)
Henry, Alaina L., Turner, Jean L., Beck, Sara C., Crostwaite, Lucian P., Meier, David S.
We present high spectral resolution (v~12-16 km/s) Brackett line spectroscopy of the blue compact dwarf galaxy Henize 2-10 made with NIRSPEC on the Keck Telescope. The spatial resolution is seeing...
High Resolution Radio Maps of Four Nearby Spiral Galaxies (2006)
Tsai, Chao-Wei, Turner, Jean L., Beck, Sara C., Crosthwaite, Lucian P., Ho, Paul T. P., Meier, David S., ...
We report subarcsecond-resolution VLA imaging of the centers of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, 7 - 12 compact radio continuum sources were...
Subarcsecond-Resolution Radio Maps of Nearby Spiral Galaxies (2006)
Tsai, Chao-Wei, Turner, Jean L., Beck, Sara C., Crosthwaite, Lucian P., Ho, Paul T. P., Meier, David S., ...
We report subarcsecond-resolution VLA imaging of four nearby spiral galaxies: IC 342, Maffei II, NGC 2903, and NGC 6946. In each galaxy, compact radio continuum sources are identified in the central...
MERLIN and VLA Observations of VII Zw 19: Distant Cousin of M82 (2004)
Beck, Sara C., Garrington, S. T., Turner, Jean L., Van Dyk, Schuyler D.
We have observed the starburst dwarf galaxy VII Zw 19 at subarcsecond resolution with the MERLIN and MERLIN+EVN networks at 18 cm, with MERLIN at 6 cm, and with the VLA in A array at 6 and 2 cm. The...
Stark, Ronald, Sandell, Goeran, Beck, Sara C., Hogerheijde, Michiel R., Van Dishoeck, Ewine F., Van Der Wal, Peter, ...
We present deep images of dust continuum emission at 450, 800, and 850 micron of the dark cloud LDN 1689N which harbors the low-mass young stellar objects (YSOs) IRAS 16293-2422A and B (I16293A and...
The Birth of a Super Star Cluster: NGC 5253 (2004)
Turner, Jean L., Beck, Sara C.
We present images of the 7mm free-free emission from the radio "supernebula" in NGC 5253 made with the Very Large Array and the Pie Town link. The images reveal structure in the nebula, which has a
Watching the Birth of Super Star Clusters (2003)
Turner, Jean L., Beck, Sara C.
Subarcsecond infrared and radio observations yield important information about the formation of super star clusters from their surrounding gas. We discuss the general properties of ionized and...
Molecular Gas and the Young Starburst in NGC 5253, Revisited (2002)
Meier, David S., Turner, Jean L., Beck, Sara C.
We report the detection of CO(2-1) and 3.1 mm and 1.3 mm continuum emission towards the extremely young starburst in NGC 5253, with data taken from the Owens Valley Millimeter Array. Faint CO...
Molecular Gas and Star Formation in NGC 3077 (2001)
Meier, David S., Turner, Jean L., Beck, Sara C.
We present high resolution (~2.5'') CO(1-0) and CO(2-1) images of the central kiloparsec of NGC 3077 made with the Owens Valley Millimeter Array. CO emission is distributed in three major complexes...
Infrared Emission from the Radio Supernebula in NGC 5253: A Proto-Globular Cluster? (2001)
Gorjian, Varoujan, Turner, Jean L., Beck, Sara C.
Hidden from optical view in the starburst region of the dwarf galaxy NGC 5253 lies an intense radio source with an unusual spectrum which could be interpreted variously as nebular gas ionized by a...
Warm Molecular Gas in Dwarf Starburst Galaxies: CO(3-2) Observations (2000)
Meier, David S., Turner, Jean L., Crosthwaite, Lucian P., Beck, Sara C.
Eight dwarf starburst galaxies have been observed with the Caltech Submillimeter Observatory (CSO) telescope in the CO J= 3 - 2 transition. The galaxies observed are He 2-10, NGC 5253, NGC 1569, NGC...
