Hubble Space Telescope Call for Proposals for Cycle 11

8.12 Abstract

---

(This is item 11 in the GO/SNAP template; it is item 8 in the AR/Theory template.)

Please write a concise abstract describing the proposed investigation, including the main science goals and the justification for requesting observations or funding from HST. The abstract must fit on the first page of the printed proposal (this means in practice that it should be less than approximately 16 lines in 12 pt. font).
