| Description |
English: As the title indicates, these are all of the galaxies observed for a particular Hubble program. Some of them are remarkable and beautiful examples of gravitational lensing. Others, maybe not so much. Nonetheless, here they all are for you to look at and try to find the lenses yourself.
Something you might wonder is that if even Hubble can barely see what's going on here, how did they know to look? And the answer to that is, as with many things in astronomy, spectroscopy. Reading the observation description, we learn that they created an algorithm to search nearly a million spectra to find a couple hundred candidates that seemed to have a foreground and background object. Then they whittled it down to a few for Hubble to look at. Translation: These are rare and hard to find. From left to right, top to bottom, here are the galaxies, along with a note on whether the galaxy has a lens or not, as determined by Treu, et al. See if your answers match the astronomers'. Row 1 SDSSJ0820+4847 (Yes) SDSSJ0841+3824 (Yes) SDSSJ1015+1750 (No) SDSSJ1029+0420 (Yes) SDSSJ1032+5322 (Yes) SDSSJ1037+3517 (Yes) SDSSJ1056+0005 (No) Row 2 SDSSJ1103+5322 (Yes) SDSSJ1117+4704 (Yes) SDSSJ1203+2535 (Yes) SDSSJ1228+3743 (Probably) SDSSJ1258-0259 (No) SDSSJ1300+3704 (No) SDSSJ1321-0115 (Maybe) Row 3 SDSSJ1331+3628 (Yes) SDSSJ1410+0205 (Maybe) SDSSJ1521+5805 (Maybe) SDSSJ1556+3429 (Maybe) SDSSJ1703+2451 (Yes) SDSSJ2141-0001 (Yes) SDSSJ2210-0934 (Maybe) Luminous and dark matter in disk galaxies from strong lensing and stellar kinematics For most of these, the following is true. Some of them have an extra little bit of data from another camera and even another proposal. You can always ask if you need details, but I doubt anyone needs to know. Red: WFPC2 F814W Green: WFPC2 F606W Blue: WFPC2 F450W North is up for all galaxies. |
