The schedulability was very limited for four targets in the previous version. From Crystal's help, we have adjusted the roll angles. -912507925 ----- Attempting Submission 1 (Thu Jul 24 18:33:14 GMT 2014) ----- HST Phase II Proposal 13732 (QUADS_c22_2.apt) successfully submitted. ----- Attempting Submission 2 (Thu Jul 24 23:57:47 GMT 2014) ----- HST Phase II Proposal 13732 (QUADS_c22_2.apt) successfully submitted. ----- Attempting Submission 3 (Thu Jul 24 23:59:56 GMT 2014) ----- ----- Attempting Submission 4 (Tue Aug 05 06:11:44 GMT 2014) ----- Detecting dark matter substructure with narrow line lensing The abundance of low mass halos is one of the key predictions of LCDM and remains at apparent odds with observations of luminous structure. Strong gravitational lensing provides a straightforward means of testing this theory as it enables the detection of dark matter subhalos at cosmological distances, without requiring the structure to contain any baryons at all. The fluxes of strongly lensed, parsec scale sources in particular, are excellent probes as they are extremely sensitive to the presence of low mass subhalos, while still being extended enough to remain unaffected by microlensing by stars which is a dominant contaminant for smaller sources. Traditionally this field has been limited to the analysis of the small number of strongly lensed, radio-loud quasars. Quasar narrow-line emission offers an alternative to radio. It is also parsec scale and microlensing free, but has the benefit of detectable in a much larger sample of systems. This proposal will combine milliarcsecond astrometry, and percent level photometry attainable with WFC3 IR grism, in order to measure spatially resolved narrow line lensing in six new systems, which cannot be studied from the ground. We have demonstrated that data of this quality can be used to detect subhalos as small as a million solar masses. This proposal will double the sample of systems which can be used to detect dark, low mass substructure using flux ratio anomalies. We will use the same procedure as was used in GLASS and 3D HST: First we take a short exposure using either F105W or F140, and then a longer grism exposure with G102 or G141 respectively. We dither on a sub-pixel pattern to obtain better spatial resolution after data reduction.
