These galaxies generally contain far more W-R line_4: stars than the Milky Way, M31, and other normal galaxies. The ultraviolet line_5: FOC images and FOS spectra will be combined with optical and infrared line_6: data as part of a large effort to perform a broad, systematic analysis line_7: of the properties of W-R galaxies. The UV data obtained with HST will line_8: provide crucial constraints on the hot star (O and W-R) populations, and line_9: will lead to a better understanding of the physical conditions, initial line_10: mass functions, and starburst parameters of these galaxies. The overall line_11: continuum will be analyzed within the framework of evolutionary and line_12: spectral synthesis models that we are developing. Quantitative line_13: spectroscopy of UV resonance lines will allow us to study the hot star line_14: populations in detail, and to directly measure the number of OB stars line_15: within these galaxies. Our main goal is to determine which physical line_16: properties of W-R galaxies (e.g., IMF slope, chemical composition, age, line_17: strength and duration of the starburst) have led to the production of line_18: large numbers of W-R stars. The results of this study will have line_19: important implications for our understanding of W-R galaxies, and also line_20: of starburst and emission-line galaxies in general. ! ! end of abstract general_form_proposers: lname: CONTI fname: PETER title: PI mi: S. inst: UNIVERSITY OF COLORADO country: USA ! lname: FILIPPENKO fname: ALEXEI mi: V. inst: UNIVERSITY OF CALIFORNIA, BERKELEY country: USA ! lname: LEITHERER fname: CLAUS inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA esa: Y ! lname: ROBERT fname: CARMELLE inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: SARGENT fname: WALLACE mi: L. inst: CALIFORNIA INSTITUTE OF TECHNOLOGY country: USA ! lname: VACCA fname: WILLIAM mi: D. inst: UNIVERSITY OF CALIFORNIA, BERKELEY country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: We would like to obtain FOC images of ALL of our W-R galaxies at 1600A. line_2: We anticipate that many if not most of our systems will contain multiple line_3: knots of hot stars which will readily stand out against the overall line_4: galaxy background in these UV wavelengths. Ground-based observations line_5: suggest typical knot-sizes of approximately 3". The FOC/48 + F140W line_6: set-up meets the following requirements: (i) large FOV; (ii) image scale line_7: small enough to maximize count-rate; (iii) sampling large enough to line_8: study spatial morphology; (iv) no significant red leak. The FOC data line_9: serve a threefold purpose: (i) UV morphology; (ii) flux measurement for line_10: FOS; (iii) check for potential difficulties in the FOS target line_11: acquisition. line_12: We would also like to obtain FOS spectra of the brightest knots of line_13: some W-R galaxies. The objects will be selected on the basis of the FOC line_14: data; There may be more than one knot per galaxy. line_15: The scientific goal can be best achieved with the FOS and gratings line_16: G130H and G190H. We intend to use the blue-side detector for both line_17: gratings. The positions and the exposure times of the candidates for line_18: FOS spectroscopy will be updated in order to ensure successful target line_19: acquisition. A peak-up technique is used for the TA. ! question: 4 section: 1 line_1: There are no UV images of W-R galaxies yet published. FOC is the only line_2: UV imaging device presently available. line_3: It is the combination of the superior resolution (IUE: 6A; FOS: 3A for line_4: a knot of 2-3") and vastly better S/N (IUE: typically 10; FOS: 35 for line_5: our proposed observations) of HST data which provide a dramatic line_6: improvement. STRONG lines (like C IV) can be modeled quantitatively line_7: with HST, and WEAKER lines (like N IV 1718, which is an important line_8: signature of hot EVOLVED stars) can only be detected with HST, in line_9: contrast to IUE. ! question: 5 section: 1 line_1: The FOC exposures should be scheduled as early as possible in Cycle 2 line_2: since the results (morphology; flux levels) will be used to select line_3: the targets for spectroscopy with the FOS. ! question: 6 section: 1 line_1: No special calibrations are requested. According to the FOC instrument line_2: scientist, PSF's will be provided by STScI. ! question: 7 section: 1 line_1: The general management of the observations (including the ground line_2: observations) and the data reduction and interpretation will be line_3: coordinated by Peter Conti. line_4: Reduction of the FOC images with deconvolution techniques will be done line_5: under P. Conti's supervision at JILA utilizing a graduate student RA. line_6: FOS deconvolution will be carried out by Claus Leitherer. P. Conti is line_7: also in charge of the pre-analysis of the HST observations (line line_8: identification, interstellar extinction...). Other observations from line_9: the ground are to be acquired, reduced and analysed by Alex Filippenko, line_10: Wal Sargent and Bill Vacca. line_11: The population synthesis models will be done at STScI by Carmelle line_12: Robert and Claus Leitherer. All co-Is will be intimately involved with line_13: data analysis and interpretation. ! question: 8 section: 1 line_1: The HST observations are supported by ground-based observations. There line_2: is no need for simultaneous observations. ! !end of general form text general_form_address: lname: CONTI fname: PETER mi: S title: DR. category: PI inst: JILA/UNIV.
