PI: JAMES FLOOD SCHERING-PLOUGH RESEARCH INSTITUTE ------------------------------------------------------------------------------------ 6. 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. ------------------------------------------------------------------------------------ 6872( 10) - 05/14/97 17:22 - [ 2] Observations 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.

All issues pertaining to the implementation, execution, and data analysis of this program should be brought to Max's attention. ------------------------------------------------------------------------------------ Data Distribution Media: 8MM Blocking Factor: 10 Ship To: PI_address Ship Via: UPS Email: floodj@eclipse.net,mutchler@stsci.edu ------------------------------------------------------------------------------------ 6872( 10) - 05/14/97 17:22 - [ 3] TARGET LIST a) Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC1808 GALAXY,SPIRAL,DUST RA=5H 7M 42.0S +/- 2S, DEC=-37D J2000 V = 989 V = 10.7+/-0.2 LANE,STARBURST, 30' 51.0" +/- 10", PLATE-ID=00AN WIND,FILAMENT Comments: A Sersic-Pastoriza galaxy 6872( 10) - 05/14/97 17:22 - [ 4] Visit: 01 Visit Requirements: ORIENT 245D TO 265D On Hold Comments: Additional Comments: Exposures ------------------------------------------------------------------------------------------------------------------------------------ Exposure| Target |Instr | Oper. | Aper |Spectral|Central| Optional |Num| Time | Special Number | Name |Config| Mode |or FOV |Element |Waveln.| Parameters |Exp| | Requirements ------------------------------------------------------------------------------------------------------------------------------------ 1 NGC1808 WFPC2 IMAGE PC1-FIX F814W CR-SPLIT=NO 2 140 S Comments: Broad band I exposure ------------------------------------------------------------------------------------------------------------------------------------ 2 NGC1808 WFPC2 IMAGE PC1-FIX F658N CR-SPLIT=NO 2 700 S Comments: Narrow band H-alpha exposure ------------------------------------------------------------------------------------------------------------------------------------ 3 NGC1808 WFPC2 IMAGE PC1-FIX F675W CR-SPLIT=NO 2 120 S Comments: Broad band R exposure for continuum subtraction from the H-alpha image ------------------------------------------------------------------------------------------------------------------------------------ 6872( 10) - 05/14/97 17:22 - [ 5] Summary Form for Proposal 6872 Item Used in this proposal ------------------------------------------------------------------------------------------------------------------------------------ Configurations WFPC2 ------------------------------------------------------------------------------------------------------------------------------------ Opmodes IMAGE ------------------------------------------------------------------------------------------------------------------------------------ Optional Parameters CR-SPLIT=NO ------------------------------------------------------------------------------------------------------------------------------------ Proposal Category GO/AM ------------------------------------------------------------------------------------------------------------------------------------ Scientific Category AGN ------------------------------------------------------------------------------------------------------------------------------------ Special Requirements ORIENT 245D TO 265D ------------------------------------------------------------------------------------------------------------------------------------ Spectral Elements F814W F658N F675W ------------------------------------------------------------------------------------------------------------------------------------ Target Names NGC1808 ------------------------------------------------------------------------------------------------------------------------------------
