This is a HST GO proposal in Cycle 23 from Tsumura et al. -498489103 Assigned ID: 172 ----- Attempting Submission 1 (Thu Apr 09 05:35:09 GMT 2015) ----- Our observations of Galilean satellite eclipses will be conducted with non-sidereal tracking on Jupiter (outside of the FoV). To do this, Visit will be set to track on Jupiter and offset to a target satellite by using a position angle and radius. Because we don't know observable eclipses, however, Visits in this submitted file are set to track on the Galilean satellites (not Jupiter), and the position angle offsets were not set yet 1451109418 ----- Attempting Submission 1 (Thu Jul 02 02:42:51 GMT 2015) ----- Absolute Measurement of the Cosmic Near-Infrared Background Using Eclipsed Galilean Satellites as Occulters The Cosmic Infrared Background (CIB) as an integrated history of the early universe is important for the study of unresolved star formation. However, previous CIB measurements suffer from residual contamination from strong foreground emission (e.g. the zodiacal light). We propose to observe Galilean satellites eclipsed in the shadow of Jupiter as occulting spots at near-infrared wavelengths in order to detect the absolute CIB intensity without any zodiacal light subtraction error. The zodiacal light originates inside the orbit of Jupiter; since the Galilean satellites in eclipse shield all light beyond the Jovian orbit, they should be detected as 'dark spots' if the strong CIB implied by previous observations exists. The intensity deficit of this dark spot relative to the surrounding sky directly measures the brightness of the CIB, free from any assumptions about the zodiacal light. The size of the dark spot is approximately 1 arcsec in diameter and the predicted surface brightness is 50 nW/m2/sr lower than that of surrounding sky brightness, which can be detected by WFC3 IR imaging with F167N filter for one orbit integration with S/N=10 even in the strong Jovian stray light environment. Our previous observations revealed that deep eclipses are required to reduce the effects from forward-scatterd sunlight within the Jovian upper atmosphere. The deepest such eclipses will occur in this Cycle 23 season, and next chance to observe such deep eclipses is six years after owing to Jupiter's orbital period. Therefore, observations in this Cycle 23 are highly required. These new observations will definitively prove if the technique can be made to work. Our observational targets are the Galilean satellites (Europa, Ganymede and Callisto), which are non-stationary targets. For example, in a Ganymede eclipse case on Dec.12th, 2015, the diameter of Ganymede is 1.4 arcsec circle, it is located at 14-51 arcsec from Jovian limb, and its relative speed to the Jupiter is 5.7*10^-3 arcsec/sec. Our strategy is to measure the CIB brightness as a dark spot, and the foreground sky brightness can be evaluated locally around the dark spot itself. Previous direct measurements of CIB indicate that the absolute CIB brightness is ~50 nW/m2/sr at around 1.6 um. This is equivalent to a 23 Vega magnitude/arcsec2 deficit against a sky background, which can be detected by WFC3 IR imaging with F167N filter by 40 minutes (equivalent to one orbit) of integration with S/N=13. In addition, if the bright CIB reported by direct observations does not exist, the integrated light of galaxies of ~10 nW/m2/sr at around 1.6 um still should exist, which can be detected by WFC3 IR imaging with F167N filter with 40 minutes integration with S/N=3. This means that an HST observation of one orbit guarantees the detection of the dark spot of the eclipse, although we cannot observe throughout the entire eclipse (roughly two hours) because of the occultation of Jupiter by the Earth relative to HST. The greatest difficulty in this observation results from scattered light due to the close proximity of Jupiter to the target satellites, which will reduce the estimates S/N described above. However, Jupiter is dark in our observed bands (F139M and F167N) owing to the methane absorption in the Jovian atmosphere, thus stray light from Jupiter is also reduced. Our previous observation of Europa eclipse at F139M in Cycle 20 shows that Jovian stray light at 30 arcsec from Jovian limb was almost comparable to the sky background level (the zodiacal light). Since Jupiter is darker at F167N than at F139M, we can measure the brightness of the satellites in eclipse at both F139M and F167N with the estimated S/N described above. As a result, we propose two orbits per filter (F139M and F167N) per satellite (Europa, Ganymede and Callisto), thus twelve orbits in total. Two orbits are required to obtain sufficient signals in the case of no CIB excess scenario. In addition, we can obtain the CIB spectral shape from two different filters, which is scientifically important to investigate the origin of the CIB excess. Observations using the different satellite eclipses reduce the systematic uncertainty of scattered sunlight from Jovian upper atmosphere if the effect of the scattered sunlight is not negligible, because the effect of the sunlight depends on the distance between Jupiter and satellites in eclipse. The greatest difficulty in this observation results from scattered light due to the close proximity of Jupiter to the target satellites. Therefore, we will keep Jupiter out of the detector field of view (FoV) during the observation to avoid stray light from Jupiter. Observations will be conducted with non-sidereal tracking on Jupiter (outside of the FoV) to fix the stray light pattern on the detector during the observation. This will minimize the systematic error of the Jovian stray light. Since the relative speed of the target satellites to Jupiter is ~0.006 arcsec/sec, short integrations (<20 sec) are required to avoid smearing of the target satellite. Letting the eclipsed satellite move relative to the detector using Jupiter tracking has the advantage of effectively dithering the observations so that we can average out any detector issues such as scattered earthlight, structure in the darks, and the dark features called "blobs" in particular (the latter are believed to result from debris on the pick-off optics). In addition, the spider pattern runs diagonal direction on the detector array around any bright sources (even from Jupiter located at outside of FoV). Thus we need to keep this spider pattern of Jupiter or other bright sources off of target satellites in eclipse by rolling the scope to align the target satellite in eclipse and Jupiter out of FoV to be on either the same x- or y-coordinate. This rolling adjustment was also successful in our Cycle 20 observations. We emphasize that we know the ephemeri of Galilean satellites with great precision; the size and location of the Galilean satellites will be accurately known, and therefore easily differentiated from detector effects.
