Frank Winkler Middlebury College N ------------------------------------------------------------------------------------ Abstract The composition and dynamics of supernova remnants inform us on the explosion mechanism of the supernova and the evolution of the progenitor. The Galactic remnant G292.0+1.8 is an evolved remnant rich in emission from shocked ejecta and circumstellar material. It is also optically bright in [OIII] emission. Here we propose for a 500ks observation of G292. We will perform Doppler tomography on the ejecta in order to measure their 3D dynamics. Additionally, we request 100ks of Chandra ACIS-I time to measure the expansion of the forward shock and motion of the pulsar, and 8 orbits of HST/ACS time to measure the transverse motion of the bright optical knots. Our proposed program will be complemented by a ground based spectroscopic survey and approved XRISM observations. ------------------------------------------------------------------------------------ Observations Description ------------------------ The goal is to obtain a set of ACS/WFC images in order to perform proper motion measurements of the O-rich and S-rich ejecta. We will use the ACS F475W and F625W filters in order to isolate [O III] and [S II] emission from high velocity ejecta. There are 4 target regions which will be imaged, in order to cover the eastern region of the SNR, and a portion of bright emission in the center-west. To do this we have constructed an observing program of four (4) visits. Each of the visits target a region of the SNR with two ACS filters (F475W and F625W) using a 4x500 sec exposure dithered using a 2 point dither pattern 17901( 4) - 31-Mar-2025 16:20:30 - [ 2] ACS-WFC-DITHER-LINE spaced by 3 arcseconds, with a 2 point subpattern within each point. Due to visibility constraints, one orbit will be needed for each filter and region combination, resulting in a total of 8 orbits. We initially were granted CVZ time through the joint XMM-Newton program, but there is no CVZ time for this target in the current cycle. We have therefore adjusted the pointings of 4 of our targets, and dropped two other regions which were listed in our phase 1 submission. We have listed roll requirements for each visit. Given these requirements, our target is schedulable for a two week period beginning June 6, and for approximately 3 weeks beginning on September 8 and again on November 22, 2025. ------------------------------------------------------------------------------------ 17901( 4) - 31-Mar-2025 16:20:30 - [ 3] TARGET LIST Fixed Targets ------------------------------------------------------------------------------------------------------------------------------------ Tar| Target | Target | Target |Coord | Radial | Flux data No | Name | Description | Position |Eqnx | Vel. | ------------------------------------------------------------------------------------------------------------------------------------ 1 SNR-G292.0+0 ISM, SNR RA=11H24M43.1566S, J2000 V = 12 +/- 1.0 1.5e-15 1.8-NE DEC=-59D13'22.60" erg/cm2/s/arcsec2 in [O III] 5007 Reference Frame: ICRS Extended: YES Comments: This object was generated by the targetselector and retrieved from the SIMBAD database.
