While I have allowed for 4 orients separated by 90 degrees, since I want to cover the same region on the sky as an early proposal, only two of these orientations have visibility intervals because of the way I have packed individual orbits. 812576058 ----- Attempting Submission 1 (Fri Jul 15 16:24:02 GMT 2016) ----- There are warnings, but I believe these are expected for a mosaic and the default wfc3 dither blob pattern with a two point subdither. What Makes Radio-detected and Optically-detected Supernova Remnants in NGC6946 Different? In the Galaxy, most SNRs were first detected as extended non-thermal radio sources. By contrast, in galaxies beyond the Magellanic Clouds, most SNRs have been identified as emission nebulae with elevated [S II]:Ha emission ratios compared to HII regions. NGC6946, which has had more historical SNe than any other galaxy, is one of the very few galaxies with both a large number of radio and optical SNRs and SNR candidates. Surprisingly, the radio and the optical samples of SNRs in this (and other) galaxies are almost disjoint, possibly due to the fact that the radio-detected objects tend to be located in or very near HII regions with higher than normal extinction. If this is correct, these radio SNRs should be detectable as nebulae with strong [Fe II] emission lines in the near IR, since extinction should be much less of a factor and since the ratio of [Fe II]:Pa Beta is expected to be high, of order 10, in shocked SNR gas, and very low in photoionized regions. To find out, we propose to use existing Pa Beta and new [Fe II] WFC3 imagery of NGC6946, along with the results of our new radio and optical imaging and spectroscopic surveys, to find the radio sample. Since we also should detect many, if not all, of the optically identified SNRs in [Fe II], we will be able to compare the properties (diameter distribution, [Fe II] flux) of the two sub-populations in order to improve our understanding both of the selection effects and of the evolutionary state of the populations. More generally, the combination of radio, optical, IR and X-ray data (from existing Chandra observations) will allow us to complete one of the most detailed characterizations of SNRs in any nearby galaxy. This is a project to observe NGC6946 with the [Fe II] 1.64 micron (F164N) and H-band (F160W) filters. The continuum filter is primarily used for star subtraction. Our goal is to identify SNRs in NGC6946 in the IR. Our observational definition of an IR SNR for the purpose of this program is an emission nebulae with a large [Fe II]:Pbeta ratio. The Pbeta images exist as archival data, obtained in program 14156 (Leroy PI). Our observing strategy, which involves obtaining a 3 x 3 mosaic of the innner part or the galaxy with WFC3/IR, is very similar to the earlier progam. Our tight orientation requirement maximizes the overlap between the earlier program, and also allows us to cover most of the inner spiral arms, where the optically and radio SNRs and candidates are located.
