At these phases, normal SNe Ia have been shown to undergo a plateau phase in the near-infrared (NIR) while continuing to decline in the optical. Our sample consists of two normal SNe Ia and two peculiar SNe Iax. With two visits per SN during this phase range, we will use observations in F125W (J), F160W (H), F336W (U), and F350LP (optical) to: (1) confirm the J-band plateau for normal SNe Ia; (2) test whether the plateau is caused by scattering of photons from the UV/optical to the NIR; (3) test whether SNe Iax also exhibit a NIR plateau; and (4) detect the surviving white dwarf progenitors of SNe Iax. At late times, observations drive theory, and ours will help shed light on the progenitor and explosion physics of both normal SNe Ia and their peculiar Iax cousins. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will use WFC3 to observe four Type Ia supernovae with two visits to each supernova. Every visit will be composed of a single orbit. SNe 2020hvf and 2020uxz are brighter than 2020udy and 2020kyg. The brighter supernovae will be observed with four filters: WFC3/UVIS F350LP and F336W and WFC3/IR F125W and F160W. For the fainter supernovae, we will drop the F336W filter. The IR observations use a 3pt dither. In orbits that include both F336W and F350LP, we will use a 2pt dither (to limit overheads). In orbits where we only use F350LP, we will use a 3pt dither instead. Each visit has been given a time window of ~11 days to increase the scheduleability of the observations. The same is true 16497( 11) - 06-Aug-2021 17:43:36 - [ 2] for the total exposure time per orbit.; for two of our targets (2020uxz and 2020udy), we do not make full use of the orbits in order to maximize their scheduleability. The observations from the first visit to each supernova will be reduced and analyzed immediately in order to try and localize the supernova and measure its brightness in all filters. This will inform any potential changes to the filter loadout and exposure times for the second visit (e.g., if the supernova does not appear in a certain filter or is expected to drop out in that filter, we may choose to shift the exposure time into another filter in which the supernova will definitely be visible). We chose WFC3 UVIS1-2k2k subrasters for the FOV, but only because the UVIS1 full FOV (which we usually use) seemed to cost too much in overhead. For each target, the specific subraster (e.g., 2k2a or 2k2d) was chosen to capture as much of the host galaxy as possible in the FOV, while still including the target itself. ------------------------------------------------------------------------------------ 16497( 11) -
