Abstract:                  

A high resolution examination of the galactic core of NGC 1808 can resolve
questions as to the nature of it's energetic core "hot spots" variously
attributed to unusual circumnuclear starburst activity, massive supernova 
remnants or black hole accretion disk models. Also present are pronounced
radial dust filaments streaming from the core of NGC 1808 in association
with large gaseous polar outflows, suggestive of galactic fountaining.

Questions                     

Observing_Description:

High resolution WFPC2 imaging will be performed on the core region of NGC 1808,
a morphologically unusual galaxy. These images will reveal important
information about the optical "hot spots" and their relationship to the weak
Seyfert-like core of the galaxy. The structure and exact source of the 
radial filaments and their relationship to the gaseous outflow and
superwind could be revealed. Optical counterparts to the rotating
molecular gas rings reported by radio observations may be detected.
Evidence of star formation in the halo can resolve questions about
galactic fountain star formation theories. The spiral arms may show
evidence of gravitational interaction with nearby galaxy NGC 1792,
the alleged trigger of the starburst and tidal H-alpha chains reported
by radio observations. These images will show the HII regions, radial
jets, and high energy sources such as young star clusters. The IR image
will sample the general stellar population, and will be less affected
by young hot stars, ionized gas and the obscuring dust of the core.

Additional_Comments:

Max Mutchler is the STScI staff "mentor" (combining the roles
of Program Coordinator, Contact Scientist, and Data Analyst) 
for the PI Jim Flood, who is an amateur astronomer. 
All issues pertaining to the implementation, execution, and data analysis 
of this program should be brought to Max's attention.
