HAWC: A Next Generation All-Sky VHE Gamma-Ray Telescope
G. Sinnis, A. Smith, J. E. McEnery
The study of the universe at energies above 100 GeV is a relatively new and exciting field. The current generation of pointed instruments have detected TeV gamma rays from at least…
Ultraviolet Signposts of Resonant Dynamics in the Starburst-Ringed Sab Galaxy, M94 (NGC 4736)
William H. Waller, Michael N. Fanelli, William C. Keel +10
M94 (NGC 4736) is investigated using images from the Ultraviolet Imaging Telescope (FUV-band), Hubble Space Telescope (NUV-band), Kitt Peak 0.9-m telescope (H-alpha, R, and I bands…
Far Ultraviolet Imagery of the Edge-On Spiral Galaxy NGC 4631
Andrew M. Smith, Nicholas R. Collins, William H. Waller +10
Far ultraviolet FUV imagery of the edge-on, Sc/SBd galaxy, NGC 4631 reveals very strong FUV emission, resulting from active star formation, uniformly distributed along the galactic…
Ultraviolet Imaging of the Irregular Galaxy NGC 4449 with UIT: Photometry and Recent Star-Formation History
Robert S. Hill, Michael N. Fanelli, Denise A. Smith +6
The bright Magellanic irregular galaxy NGC 4449 was observed during the Astro-2 Space Shuttle mission by the Ultraviolet Imaging Telescope (UIT), which obtained images of a ~40 arc…
Ultraviolet Imaging of the z=0.23 Cluster Abell 2246
Robert H. Cornett, Ben Dorman, Eric P. Smith +8
We present deep ultraviolet observations of a field containing the cluster Abell 2246 (z=0.225) which provide far-ultraviolet (FUV) images of some of the faintest galaxies yet obse…
The Hot Stars of Old Open Clusters: M67, NGC 188 and NGC6791
W. Landsman, R. C. Bohlin, S. G. Neff +4
We analyze ultraviolet (~1500 A) images of the old open clusters M67, NGC 188, and NGC 6791 obtained with Ultraviolet Imaging Telescope (UIT) during the second flight of the Astro…
The Ultraviolet Imaging Telescope: Instrument and Data Characteristics
Theodore P. Stecher, Robert H. Cornett, Michael R. Greason +16
The Ultraviolet Imaging Telescope (UIT) was flown as part of the Astro observatory on the Space Shuttle Columbia in December 1990 and again on the Space Shuttle Endeavor in March 1…
Ultraviolet Imaging of the Globular Cluster 47 Tucanae
Robert W. O'Connell, Ben Dorman, Ronak Y. Shah +7
We have used the Ultraviolet Imaging Telescope to obtain deep far-UV (1620 Angstrom), 40' diameter images of the prototypical metal-rich globular cluster 47 Tucanae. We find a popu…
UIT Detection of Hot Stars in the Globular Cluster NGC362
Ben Dorman, Ronak Y. Shah, Robert W. O'Connell +7
We used the Ultraviolet Imaging Telescope during the March 1995 Astro-2 mission to obtain a deep far-UV image of the globular cluster NGC 362, which was formerly thought to have an…
UIT Astro-2 Observations of NGC 4449
Robert S. Hill, Michael N. Fanelli, Denise A. Smith +2
The bright Magellanic irregular galaxy NGC 4449 was observed by the Ultraviolet Imaging Telescope (UIT) during the Astro-2 Spacelab mission in March, 1995. Far ultraviolet (FUV) im…
Ultraviolet Signatures of Tidal Interaction in the Giant Spiral Galaxy, M101
William H. Waller, Ralph C. Bohlin, Robert H. Cornett +10
We present new evidence for tidal interactions having occurred in the disk of M101 in the last 10^8 - 10^9 years. Recent imaging of the far-ultraviolet emission from M101 by the Sh…
Ultraviolet Imaging Telescope (UIT) Observations of the Small Magellanic Cloud
Robert H. Cornett, Michael R. Greason, Jesse K. Hill +9
A mosaic of four UIT far-UV (FUV; 1620A) images, which covers most of the SMC bar, is presented, with derived stellar and HII region photometry. The UV morphology of the Bar shows…
Ultraviolet Imaging Observations of the cD Galaxy in Abell 1795: Further Evidence for Massive Star Formation in a Cooling Flow
Eric P. Smith, R. C. Bohlin, G. D. Bothun +5
We present images from the Ultraviolet Imaging Telescope of the Abell 1795 cluster of galaxies. We compare the cD galaxy morphology and photometry of these data with those from exi…
