Long Space Telescope Science Institute N ------------------------------------------------------------------------------------ Abstract Recent studies of the southern oxygen-rich supernova remnant (SNR) G292.0+1.8 have shown it to be the only Galactic SNR to exhibit all the features we expect in young remnants of core-collapse supernovae: an outer shell behind an expanding primary shock, high-velocity fragments of undiluted metal-rich ejecta, and a central pulsar surrounded by a pulsar-wind nebula. G292.0+1.8's optical emission consists of numerous knots and filaments of O- and S-rich ejecta spread throughout much of the remnant shell, many with radially oriented pencil-like geometries that may trace their origins to Rayleigh-Taylor instabilities during the SN event. The evolution and fine-scale structure of SN debris in young remnants is poorly understood and largely uncharted territory. For testing models for the distribution of metal-rich ejecta from core-collapse SNe, how the ejecta evolve and clump, and how SN shocks interact with the local circumstellar medium, the 3000-yr-old G292.0+1.8 remnant rivals the 320-yr-old Cas A remnant in importance. We therefore propose the first HST images of G292.0+1.8 in order to characterize the fine-scale spatial distribution of the ejecta, their sub-arcsecond chemical make-up, and the detailed structure and scale lengths for metal-rich SN ejecta clumps. The proposed HST images of G292.0+1.8 will be used in conjunction with existing Spitzer Cycle 1 infrared data and an upcoming 0.5 Msec Chandra X-ray image. We expect to achieve the same kind of results for G292 that have already been obtained for Cas A. High-resolution HST images of this remnant, combined with Spitzer and Chandra data and contrasted with a similar data set on Cas A, will provide superb multiwavelength benchmarks for both very young and older core-collapse SNRs. ------------------------------------------------------------------------------------ Observations Description ------------------------ This project is to image all of the known optical emission associated with the southern hemisphere SNR G292.0-1.8 using the [O III] 5007 sensitive filter F475W (broad enough to detect all the object's high velocity ejecta) along with F550M filter images to serve as continuum background image for subtraction. 10916( 8) - 13-Mar-2008 14:21:00 - [ 2] We will take images at six target regions to create a mosaic image of the whole object. In addition, we will take images at two other target locations in the remnant using the F625W and F850LP filters; one to the north and the other along the central eastern limb. In Phase I, we had thought that the eastern limb position used for creating the 2 x 6 image mosaic would work for the F625W and F850LP images, but after some more thought, it was decided to add a 8th target position that was slightly different from that of the G292-East-Central location. We call this spot the g292-East-Central-2. It differs only a bit from the G292-East-Central location but does a better job of imaging the remnant's Halpha emission structure here as seen on ground-based images. Since the supernova remnant lies inside the CVZ, we use these much longer orbits to take these images. The procedure of for taking the images is simple. Two sets of images dittered by the standard offset positioning to cover the chip gap. Real Time Justification ----------------------- Calibration Justification ------------------------- Additional Comments ------------------- Note: We have added an 8th target position (see obs. descrip. above). The Phase I Proposal did describe our intention of taking data at 8 positions, However, at the time of proposal submission, we thought we could just use one of the 6 mosaic positions for the last 8th set of images. However, after we examined the positioning of this location onto the remnant's Halpha emission structure, it was decided to specifically include an 8th target location that was close to but importantly different from the East-Central positoning so as to maximize the science return as much as possible. ------------------------------------------------------------------------------------ 10916( 8) -
