Searching for Lyman alpha Emission from FUSE Lyman Continuum Candidates
We have recently been granted time on FUSE to characterize the escape fraction of hydrogen Lyman continuum (Lyc) photons from a morphologically diverse set of star forming galaxies. The FUSE program is designed to provide ~ 5 sigma detections of Lyc photons emitted from star forming galaxies with escape fractions ~5%. With this proposal we seek hydrogen Lyman alpha (Lya) observations of a representative subset of the FUSE program targets to constrain the observational relationship between Lyc, Lya, and hydrogen Balmer line emission in these systems. Such observations explore the detailed balance between the simple optically thin (Case A) and optically thick (Case B) limits in recombination theory. The ultimate goal of this program is to quantify the relationship between escaping Lya and Lyc emission and the first structures that form in the early universe.
HST-ACS/SBC is essential for this project because it is the only instrument at present capable of providing spatial resolved imagery
and spectral isolation of Lya emission. We propose to acquire images of each object in three longpass SBC filters F125LP, F140LP and
F150LP with one orbit for each filter. All our targets have total fluxes that are within a factor of two, so using equal exposures
for all the objects and all the filters is a reasonable observing strategy. We will synthesize bandpass filters by forming
substracted images, F125 - F140 and F140 - F150, which we will refer to as S132 and S141 respectively. The S141 and F150 images will
contain mostly continuum, while the S132 image will contain continuum and any Lya emission that might be present. We require two
continuum band images (S141 and F150) to provide an estimate of the continuum present in the S132 image. The use of two continuum
bands provides a means to estimate both amplitude and slope differences in the spectral energy distributions (SED). This will
improve the accuracy of the continuum flux estimation in the S132 bandpass over that provided by a single continuum image, with which
we could only account for amplitude.
Allowing one orbit for each filter we get a total of 42 orbits. All the objects are in the north at declinations > 50deg where the
handbook tells us orbital visibility of 54 minutes can be expected. The F125LP was choosen because it effectively eliminates the
strong geocoronal Lya background. However, this filter does not block the weaker OI 1304 and 1356 lines, so we will require
observations with F125LP to be made during shadow time, which the on-line exposure time calculator (ETC) shows effectively eliminates
the OI background. The duration of shadow time is ~ half of the visibility window. The ETC shows the other two filters are
unaffected by geocoronal or zodiacal light, so they have no orbital restrictions. Allowing for 6 minutes of target acquisition and ~
3 minutes for filter changes, we arrive at a total on target orbital integration time of ~ 45 minutes = 2700 seconds. In the PhaseII
orbital planning we have asked for 9 images with 15 minute integrations in each 3 orbit visit. The filter exposure sequence is
ordered such that Orbit 1: 140-125-150, Orbit 2: 150-125-140, and Orbit 3: 140-125-150. This sequence allows the 125 filter
exposures to be made well within the shadow and period and minimizes filter changes. We have requested visibilities of 54.5 minutes
for each target.
We have created a simple SED model to derive the expected sensitivity for detecting Lya emission using these three filters. We
verified the accuracy of our model against the ETC and found excellent agreement. We find that none of our targets will exceed the
MAMA local or global countrate limits of 50 counts s^-1 pixel^-1 and 2 x 10^5 counts s^-1 respectively. In our model we assume that
the continuum flux distribution is given by a power law with a logarithmic slope defined by the GALEX fuv and nuv observed fluxes.
We find that a Lya emission line with a typical EW of 20 Ang will produce approximately 10% of the flux in the S132 bandpass. We
emphasize that an accurate estimation of the Lya signal will require an accurate estimation of the continuum for subtraction from the
combined signal in the S132 image. Measurements in the two continuum bands will provide this accuracy. In addition, the FUSE
spectra and the long wavelength GALEX bands will also provide SED constraint and a means for sanity checks.
Each object will more or less fill the SBC 35'' x 31'' aperture. We have determined an average surface brightness of the objects
from the GALEX FUV images and they range from 6.2 to 1 x 10^(-17) erg / cm^2/s/Ang/('')^2. The limit of detectability of Lya on
small angular scales will depend upon the average surface brightness of the object, the solid angle and the exposure time over which
we integrate the signal. Emission from regions with large EW's can be detected within small solid angles. Detection of a smaller EW
is possible but the corresponding limiting solid angle (and hence resolution) will be larger. For a desired signal-to-noise there is
a limiting solid angle for detection of a fixed EW in a fixed amount of observing time.
For a typical EW = 20 Ang we find a range of limiting linear resolution elements ( R_(lim) =sqrt(Omega_(lim)) where Omega_(lim) is
the limiting solid angle) for a sigma_(lim) = 5 of 0.8'' < R_(lim) < 3''. This angular scale is a good match to that achievable with
typical ground based observatories. The ancillary Ha and Hb images and follow up spectroscopy can easily be acquired at ground based
facilities, such as APO, which we have access to on a regular basis.
We note, that the FUV continuum images themselves are interesting in their own right. With them we can ask whether there are
systematic differences in the spatial distribution of the (lightly-reddened) star formation in the cases where Ly continuum is
getting out? For instance, if strong Ly continuum emitters tend to have higher star formation rates per unit area, then that might
explain way the z ~ 3 LBG sample appears to have higher Ly continuum escape fractions than the lower redshift sample. LBG are known
to have star formation rates per unit area several orders-of-magnitude higher than typical star-forming galaxies today. Finally we
note, our Lya detections will serve as excellent finding charts for COS, which has an ~ 2'' entrance slit. The observations proposed
here will allow COS to precisely point to where Lya is the brightest and enable high spectral resolution studies of the kinematics of
this exciting target set.
Bright object tool results summary:
We have run the bright object tool (BOT) on the 14 visits for our 14 targets. Seven visits (3, 4, 7, 8, 9, 13 and 14) have unknown
and health/saftey flags set while the seven other visits (1, 2, 5, 6, 10, 11 and 12) just have unknown flags set. For the most part
the unknowns are either associated with the target galaxy or don't even show up on the red digital sky survey plates, so it is
difficult to identify what sort of object the BOT is finding. Health/saftey flags are most often associated with extended target
regions that are flaged as **O5** ``worse case'' objects by the BOT. Initial checking of the integrated surface brightnesses of our
targets in the SBC channels, as provided by GALEX observations, with the ETC did not reveal any bright object protection (BOP)
health/saftey issues. We believe at this time the BOT/DSS may be inadequate for identifying bright object protection issues. Our
plan for resolving these issues is to use the available GALEX and Sloan imagery from which a complete color assessment of the
unknowns and worse case health/saftey flags can be made for all visits. We intend to work with our contact scientist to clear the
fields in question for BOP.
