The power mechanism responsible for giant Lya nebulae is a subject of intense debate. These enormous (~100 kpc) and extremely luminous (L_Lya~1E44 erg/s) systems are thought to be regions of ongoing massive galaxy formation. A number of physical mechanisms have been investigated, but observational studies have thus far been unable to unambiguously pinpoint the underlying power source in these rare systems. Up until now, one important aspect of Lya nebulae has yet to be fully explored: namely, the small-scale (sub-kpc) morphology and properties of the spatially extended UV continuum light. The morphology and color of this diffuse continuum provides a complementary means for discriminating between competing ionization scenarios --- spatially extended star formation, AGN scattered light, and gravitational cooling --- but most of the well-studied Lya nebulae lie at redshifts beyond 3 where the crucial constraint on the region of the Balmer break is difficult to obtain and existing low spatial resolution observations from the ground suffer from contamination by compact sources within these complex systems. We propose to image a new sample of systematically selected ``low'' redshift (z<2.5) Lya nebulae using ACS and WFC3 in order to disentangle the diffuse and compact continuum components in these complex sources, provide the first spatially resolved, uncontaminated measurements the color of this diffuse continuum component, assess the evolutionary state of the galaxies within the nebula, and put new constraints on the power source responsible for giant Lya nebulae. The primary goals of this program are to study the internal structure and environments of a sample of 3 Lya nebulae - a class of high redshift sources that are thought to be regions of ongoing galaxy formation - in order to understand the powering mechanisms and physical conditions responsible for these rare sources. The core of the original project was the combined HST primary and parallel orbit datasets: optical and near-infrared narrow- and broad-band imaging (with ACS/WFC, WFC3/UVIS, and WFC3/IR) as well as near-infrared grism spectroscopy (with WFC3/IR) in order to correct the reddest band (F140W) for potential emission line contamination. Together these observations provide the basis for a coordinated program to (a) understand the small-scale morphology and color of diffuse UV continuum emission in a sample of Lya nebulae, providing a unique constraint on the dominant powering mechanism, (b) measure the properties of compact galaxies residing within Lya nebulae, and (c) study the large-scale environment of these systems by searching for companion Lya nebulae and Lya-emitting galaxies in the vicinity of our primary targets. After the initial Phase II submission, we were alerted by the ACS team that the existing CTE correction software may not be sufficient to correct our extended sources and that either we should shift our targets to the edge of the detector to minimize CTE problems or switch to WFC3-UVIS. Moving the targets to the detector edge was not tenable as it would cut out roughly half of the surrounding galaxy environment, thereby undermining an important part of our science program. We therefore filed a Change Request and were approved to switch our ACS primary observations to WFC3-UVIS and our parallel observations to ACS. The change to WFC3-UVIS does result in lower SNR measurements, particularly in the F814W filter; however, our estimates showed that the data will still allow us to disentangle potential power sources responsible for the diffuse continuum emission in Lya nebulae. For the parallel program, since the narrow-band Lya filters we had originally chosen do not exist on ACS, we have substituted the same broad-band filters as the concurrent primary observations. The goal of the parallels remains finding nearby Lya nebulae, but in this case via the extended continuum emission rather than Lya. As we argued in our original proposal, the proposed integration times are sufficient to detect diffuse continuum from Lya nebulae similar to our primary targets at good SNR. Total Orbits: Primary - 32 Parallel - 11 The details of the observing for each target, instrument, and spectral element are below: Target: PRG1 1. WFC3-UVIS Imaging F475W - 3 orbits We will take 6 exposures - 2 exposures per orbit (approximately 1400s per exposure). We will use the default WFC3-UVIS-GAP-LINE pattern (to dither over the chip gap) and WFC3-UVIS-DITHER-LINE-3PT (to sample the PSF) for these 6 exposures centered on aperture "UVIS" plus an additional POS-TARG offset of (-3,0) arcsec to move this extended target completely off the amplifier edge. We have no orientation restrictions for these exposures. 2. WFC3-UVIS Imaging F814W - 6 orbits We will take 12 exposures - 2 exposures per orbit (approximately 1400s per exposure). We will use the default WFC3-UVIS-GAP-LINE as the primary pattern (to dither over the chip gap) and WFC3-UVIS-DITHER-BOX as the secondary pattern (to sample the PSF) for the first 8 exposures centered on aperture "UVIS" plus an additional POS-TARG offset of (-3,0) arcsec to move this extended target completely off the amplifier edge. The final 4 exposures will use the default WFC3-UVIS-GAP-LINE as the primary pattern and WFC3-UVIS-DITHER-LINE as the secondary pattern centered on the "UVIS" aperture plus an additional POS-TARG offset of (-3,0) arcsec from the "UVIS" aperture. We require the orientation to be the same as the F475W observations for this target (#1). 3. WFC3/IR Grism G141 - 1 orbit We will first take a direct image through the "GRISM1024" aperture with the F140W filter (NSAMP=15, SPARS25, approximately 370s). We will then take 6 grism exposures (NSAMP=15, SPARS25, approximately 370s). We will use the default WFC3-IR-DITHER-BLOB as the primary dither pattern to dither over detector defects and the WFC3-IR-DITHER-3PT as a secondary dither pattern to provide subpixel sampling. The grism observations will use aperture "GRISM1024". We require the orientation to be the same as the F475W observations for this target (#1). 4. WFC3/IR Imaging F140W - 4 orbits We will take 16 exposures - 4 exposures per orbit (NSAMP=15, SPARS50, approximately 750s per exposure). We will use the default WFC3-IR-DITHER-BLOB as the primary dither pattern to dither over detector defects ("blobs") and the WFC3-IR-DITHER-BOX-MIN as a secondary dither pattern to provide subpixel sampling. Both patterns will be centered on aperture "IR". We require the orientation to be the same as the F475W observations for this target (#1). Target: PRG2 5. WFC3-UVIS Imaging F606W - 2 orbits We will take 4 exposures - 2 exposures per orbit (approximately 1400s per exposure). We will use the default WFC3-UVIS-GAP-LINE as the primary pattern (to dither over the chip gap) and WFC3-UVIS-DITHER-LINE as the secondary pattern (to sample the PSF) for these 4 exposures centered on aperture "UVIS" plus an additional POS-TARG offset of (-3,0) arcsec to move this extended target completely off the amplifier edge. We have no orientation restrictions for these exposures. 6. WFC3-UVIS Imaging F814W - 4 orbits We will take 8 exposures - 2 exposures per orbit (approximately 1400s per exposure). We will use the default WFC3-UVIS-GAP-LINE as the primary pattern (to dither over the chip gap) and WFC3-UVIS-DITHER-BOX (to sample the PSF) for these 8 exposures centered on aperture "UVIS" plus an additional POS-TARG offset of (-3,0) arcsec to move this extended target completely off the amplifier edge. We require the orientation to be the same as the F606W observations for this target (#5). 7. WFC3/IR Grism - 1 orbit We will first take a direct image through the "GRISM1024" aperture with the F140W filter (NSAMP=15, SPARS25, approximately 370s). We will then take 6 grism exposures (NSAMP=15, SPARS25, approximately 370s). We will use the default WFC3-IR-DITHER-BLOB as the primary dither pattern to dither over detector defects and the WFC3-IR-DITHER-3PT as a secondary dither pattern to provide subpixel sampling. The grism observations will use aperture "GRISM1024". We require the orientation to be the same as the F606W observations for this target (#5). 8. WFC3/IR Imaging F140W - 3 orbits We will take 12 exposures - 4 exposures per orbit (NSAMP=15, SPARS50, approximately 750s per exposure). We will use the default WFC3-IR-DITHER-BLOB as the primary dither pattern to dither over detector defects and the WFC3-IR-DITHER-BOX-MIN as a secondary dither pattern to provide subpixel sampling. The first 8 exposures will use the dither pattern centered on aperture "IR". The remaining 4 exposures will use the WFC3-IR-DITHER-BOX-MIN pattern offset by an amount similar to that used in the WFC3-IR-DITHER-BLOB pattern but in a different direction - (-14.25,14.25) pixels or (-1.931,1.726) arcsec. We require the orientation to be the same as the F606W observations for this target (#5). Target: PRG3 9. WFC3-UVIS Imaging F475W - 2 orbits We will take 4 exposures - 2 exposures per orbit (approximately 1400s per exposure). We will use the default WFC3-UVIS-GAP-LINE as the primary pattern (to dither over the chip gap) and WFC3-UVIS-DITHER-LINE as the secondary pattern (to sample the PSF) for these 4 exposures centered on aperture "UVIS" plus an additional POS-TARG offset of (-3,0) arcsec to move this extended target completely off the amplifier edge. We have no orientation restrictions for these exposures. 10. WFC3-UVIS Imaging F814W - 3 orbits We will take 6 exposures - 2 exposures per orbit (approximately 1400s per exposure).

We require the orientation to be the same as the F475W observations for this target (#9). 11. WFC3/IR Grism - 1 orbit We will first take a direct image through the "GRISM1024" aperture with the F140W filter (NSAMP=15, SPARS25, approximately 370s). We will then take 6 grism exposures (NSAMP=15, SPARS25, approximately 370s).

WFC3/IR Imaging F140W - 2 orbits We will take 8 exposures - 4 exposures per orbit (NSAMP=15, SPARS50, approximately 750s per exposure). We will use the default WFC3-IR-DITHER-BLOB as the primary dither pattern to dither over detector defects and the WFC3-IR-DITHER-BOX-MIN as a secondary dither pattern to provide subpixel sampling. The dither pattern will be centered on aperture "IR". We require the orientation to be the same as the F475W observations for this target (#9). Parallel Observations for PRG2 and PRG3: For two of our targets, narrowband WFC3-UVIS filters exist at the wavelength of Lya (F395N for PRG2 and FQ378N for PRG3). As Lya nebulae are known to be highly clustered [e.g., 22], we originally planned to use coordinated parallels with WFC3-UVIS (6 and 5 orbits, respectively, during ACS prime orbits) to obtain Lya imaging and look for companion Lya nebulae in regions near these two targets. In changing our ACS primary program to WFC3-UVIS and our WFC3-UVIS parallel program to ACS, doing parallel Lya imaging is no longer possible since the narrow-band filters we had chosen do not exist on ACS. Instead we will use the same broad-band filters as the concurrent WFC3-UVIS primary observations (F606W - 2 orbits, F814W - 4 orbits for PRG2; F475W - 2 orbits, F814W - 3 orbits for PRG3) in order to search for companion Lya nebulae in regions near these two targets via diffuse continuum emission rather than Lya. As we argued in our original proposal, the proposed integration times are sufficient to detect diffuse continuum from Lya nebulae similar to our primary targets at good SNR.
