Resubmitting upon the advice of Marco Chiaberge. We have limited our ACS exposures to 1000 s or less.2136870689----- Attempting Submission 3 (Wed Aug 28 19:50:07 GMT 2013) -----We have based our dither pattern on previous ramp filter observations and confirmed with Dr. Marco Chiaberge that this dither pattern will not cause problems.Green Pea Galaxies: Extreme, Optically-Thin Starbursts?The high UV luminosities, compact sizes, and enormous ionization parameters of the Green Pea galaxies make them some of the most extreme starburst galaxies known. Most importantly, due to their unusual emission line ratios and high specific star formation rates, the Green Peas are the best candidates for escaping ionizing radiation in the nearby Universe. We propose to study four Green Peas with COS FUV spectra and ACS emission line imaging to constrain the Lyman continuum (LyC) escape fraction and determine the origin of high ionization emission in these galaxies. COS spectra will set strong limits on the LyC optical depth via the residual intensity in the CII 1335 line, while the NV 1240 line will constrain the stellar population's age and ionizing flux. We will also observe the starbursts with ACS ramp filters in [OII], [OIII], HeII, and H-beta to determine whether the nebular emission is consistent with a low LyC optical depth. The [OIII]/[OII] ratio map will reveal the ionization structure of the emitting gas. If the [OIII] emission is found to be more spatially extended than the [OII] in any regions, it will imply that the regions are most likely optically thin. If HeII is found to be spatially offset from the dominant nebular emission, then we infer the presence of shocks. Correcting for this shock contribution to the observed emission is critical to accurately evaluate the LyC optical depth. These observations will either reveal the Green Peas as a class of galaxies having substantial LyC escape fractions or demonstrate that even some of the most extreme galaxies in the nearby Universe are optically thick.In selecting our sample, we chose Green Pea galaxies whose GALEX FUV magnitudes allow COS spectra with a S/N of 5 to be obtained in three orbits or less. Two of our objects, J121903 and SHOC-148, have existing COS FUV spectra in the proprietary stage (GO 12928, PI: Henry) and do not require any additional observations. For our remaining two objects, we will obtain acquisition images in the ACQ/IMAGE mode with Mirror A on COS. The acquisition exposure times were calculated for a S/N of 40, using the GALEX NUV magnitude and assuming an extended source. We calculated the surface brightness using a 1 arcsec diameter, since the galaxies are unresolved in ground-based observations. The acquisition image exposure time estimates are conservative, since the galaxies' sizes are smaller than the COS aperture.
We assumed a uniform surface brightness over a 1 arcsec diameter, since the galaxies are unresolved in ground-based observations. We will observe the two galaxies with the primary science aperture and the G160M grating. As recommended, we will use all four FP-POS settings. The spectral quality and exposure times requested are consistent with the COS spectra used in Heckman et al. (2011), which have a S/N greater than 4.6 per resolution element. We calculated exposure times and buffer times for the COS observations with the Spectroscopic Exposure Time Calculator (ETC) using the GALEX FUV magnitudes and assuming a 3 kpc diameter for each galaxy, consistent with the HST Pea images presented in Cardamone et al. (2009). Our exposure times are consistent with exposure times used by Heckman et al. (2011). We have used the bright object tool to verify that there are no bright objects near our targets. We estimated the V-band magnitudes by measuring the flux between 5025 and 5875 Angstroms in the SDSS spectra.
HST's resolution of 0.05 arcsec is necessary to reveal the emission line morphology of the compact, 1 arcsec, Green Pea galaxies, and the ACS ramp filters will allow us to image the [O II] 3727, He II 4686, H-beta, and [O III] 5007 emission lines at the appropriate redshifts for all four targets. We estimated surface brightnesses from the measured line and continuum fluxes in the SDSS spectra, again assuming diameters of 3 kpc. We assume the He II emission extends across only half the galaxy, as seen in IFU observations of a similar object (Izotov et al. 2006). We then determined the necessary exposure times with the ACS ETC. The emission lines in the Green Peas are exceptionally strong, particularly [O III] 5007. With four to six orbits per galaxy, we can obtain all the emission line and continuum images we require, with a signal-to-noise (S/N) of 10-20 in [O II], He II, and H-beta and 20-50 in [O III] for a 2x2 extraction window. To confirm our exposure time calculations, we examined the S/N in the existing H-beta image of J092600, a Green Pea that was observed for 2472 s in Cycle 19. The S/N estimates are conservative, as the actual emission is unlikely to be evenly distributed across the galaxy.
The He II 4686 emission line is near in wavelength to several other emission lines in the Peas' spectra. To avoid contamination by [Ar IV] 4711 and He I 4713, we plan to center the He II filter at a rest-frame wavelength of 4658 Ang. While this shift avoids [Ar IV] contamination, it does include emission from [Fe III] 4659. However, the ionization potentials of Fe+ and H differ by only a few eV, so we expect the [Fe III] emission to follow the distribution of the H-beta emission. Emission with a different spatial distribution would indicate He II emission.
Because the spectra of the Green Peas are dominated by strong emission lines, we have carefully selected regions of the spectrum free from emission lines for continuum subtraction. For [O II], we plan to image the rest-frame spectral region redward of 4110 Ang. or near 4052 Ang. with FR462N. The continuum near [O III] and He II will come from FR647M imaging redward of 5100 Ang. The continuum observations are similar in length to the emission line observations, and we calculated the S/N as described for the emission-line filters.
Charge transfer efficiency is a concern for narrow-band ACS imaging. All our exposures have an estimated background of at least 5 electrons/pixel, the minimum recommended value for imaging of extended sources. We have chosen not to use post-flash, in order to avoid washing out extended, low surface brightness emission.
Since we plan on imaging in multiple filters per orbit, the ACS overheads are a limiting factor. As with the existing observations of J092600 in FR782N, we have chosen a two-point dither pattern where possible to reject cosmic rays and hot pixels. To avoid excessive numbers of cosmic ray hits, we have made sure that our exposures are 1000 s or less, which sometimes requires increasing the total number of exposures. We have determined the necessary orbit packing and overheads for a two-point dither pattern. The ACS observations total 18 orbits and the COS observations total 6 orbits.ISM IN EXTERNAL GALAXIES12falsetrue0.00.0falsefalsefalseSUPPORTEDGALAXYDWARF COMPACTSTARBURSTThis object was generated by the targetselector and retrieved from the SIMBAD database.J2000J2000GALEX FUV mag: 20.15, NUV mag: 20.14, [O II] 3727 Flux: 263 x 10^-17 erg/s/cm^2, He II 4686 Flux: 14.4 x 10^-17 erg/s/cm^2, H-beta Flux: 402 x10^-17 erg/s/cm^2, [O III] 5007 Flux: 2959 x 10^-17 erg/s/cm^2, FR462N continuum: 2.486 x 10^-17 erg/s/cm^2/Ang, FR647M continuum: 1.694 x 10^-17 erg/s/cm^2/Ang, SDSS u: 20.27, g:20.129, r:19.344, i: 19.537, z:20.21GALAXYDWARF COMPACTSTARBURSTThis object was generated by the targetselector and retrieved from the SIMBAD database.J2000J2000GALEX FUV mag: 19.3, [O II] 3727 Flux: 751 x 10^-17 erg/s/cm^2, He II 4686 Flux: 48.7 x 10^-17 erg/s/cm^2, H-beta Flux: 1207 x 10^-17 erg/s/cm^2, [O III] 5007 Flux: 7988 x 10^-17 erg/s/cm^2, FR505N continuum: 6.59 x 10^-17 erg/s/cm^2/Ang, FR647M continuum: 3.699 x 10^-17 erg/s/cm^2/Ang, SDSS u: 19.76, g:19.544, r:18.682, i: 19.152, z:19.95,GALAXYDWARF COMPACTSTARBURSTThis object was generated by the targetselector and retrieved from the SIMBAD database.J2000J2000GALEX FUV mag: 20.2, NUV: 19.98, [O II] 3727 Flux: 751 x 10^-17 erg/s/cm^2, He II 4686 Flux: 12.81 x 10^-17 erg/s/cm^2, H-beta Flux: 864 x 10^-17 erg/s/cm^2, [O III] 5007 Flux: 6389 x 10^-17 erg/s/cm^2, FR462N continuum: 5.509 x 10^-17 erg/s/cm^2/Ang, FR647M continuum: 3.315 x 10^-17 erg/s/cm^2/Ang, SDSS u: 19.68, g:19.432, r:18.514, i:18.795, z: 19.52GALAXYDWARF COMPACTSTARBURSTThis object was generated by the targetselector and retrieved from the SIMBAD database.J2000J2000GALEX FUV mag: 19.6, [O II] 3727 Flux: 613 x 10^-17 erg/s/cm^2, He II 4686 Flux: 19.08 x 10^-17 erg/s/cm^2, H-beta Flux: 760 x 10^-17 erg/s/cm^2, [O III] 5007 Flux: 4684 x 10^-17 erg/s/cm^2, FR505N continuum: 7.215 x 10^-17 erg/s/cm^2/Ang, FR647M continuum: 3.925 x 10^-17 erg/s/cm^2/Ang, SDSS u: 19.63, g: 19.371, r:18.720, i: 19.054, z: 19.54ACS/WFCRampFilterNoNoFR423NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR462NACS/WFCRampFilterNoNoFR647MCOS/FUVSpectroscopicNoNoG160M1589ACS/WFCRampFilterNoNoFR462NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR601NACS/WFCRampFilterNoNoFR462NACS/WFCRampFilterNoNoFR647MACS/WFCRampFilterNoNoFR423NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR601NACS/WFCRampFilterNoNoFR462NACS/WFCRampFilterNoNoFR647MCOS/FUVSpectroscopicNoNoG160M1577ACS/WFCRampFilterNoNoFR423NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR551NACS/WFCRampFilterNoNoFR601NACS/WFCRampFilterNoNoFR505NACS/WFCRampFilterNoNoFR647MPOS-TARGDITHER0.145LINEfalsefalse285.28ACS-WFC-DITHER-LINE1falsePOS-TARGDITHER0.145LINEfalsefalse385.28ACS-WFC-DITHER-LINE2falsePOS-TARGDITHER0.145LINEfalsefalse885.28ACS-WFC-DITHER-LINE3falsePOS-TARGDITHER0.145LINEfalsefalse585.28ACS-WFC-DITHER-LINE4falseThe scheduling data was generated by CASM 21.2.CASM was run in Phase II mode.1381513865000283.3447563972459(Tic-Visit
