As a different approach, Mira variables exhibit promising properties as independent distance indicators. Miras are luminous in the NIR, follow tight period-luminosity relations (PLRs), and are present in all types of galaxies. Long-period Miras (400~1 year baseline. They include NGC 2525, NGC 1559, NGC 5643, and NGC 5861. (B) Existing data The existing NGC 2525 H-band time-series dataset consists of data from two recent programs. Program GO-15145 (PI: Riess) observed NGC 2525 with 10 epochs from February 2018 to March 2019. The same field was later observed with 4 epochs (one observation was off the center and will not be used for the Mira search) in Program GO-15693 (PI: Graur) from April 2019 to January 2020. The H-band data for NGC 1559, NGC 5643, and NGC 5861 are from GO-15145, with ~380 d baseline and ~10 epochs per galaxy. The exposure times for all these existing images are ~1000 s per epoch. We note that the existing data are not sufficient because (1) for a longer-period (P>700d) Mira study the NGC 2525 baseline is too short to determine their periods and mean intensities, and (2) the existing data do not include NIR colors for C-rich Mira classification, which is important to keep systematic errors low. (C) Observation: Instrument and filter Miras are very red stars (V-I~3 and ~4 mag for P<400 d and P>400 d, respectively) and thus best observed at NIR wavelengths for HST. The wide filter F160W (the HST H-band) on the WFC3 IR channel is a suitable bandpass for Mira measurements (Huang et al. 2018; 2020). This filter is also used in the above-mentioned existing data. We choose to use the same filter (F160W) and instrument (WFC3/IR) as the existing observations to extend the NGC 2525 time-series baseline, and additionally use the wide filter F110W (the HST Y/J-band) to measure the NIR color. Although the medium-band filters (F127M, F139M, and F153M) may better separate the C- and O-rich AGB stars (Boyer et al. 2013; 2017), we are limited by the imaging depth given the great distance. Ground-based observations for the LMC and M33 Miras indicate that the J-H color also effectively separates the C- and O-rich Miras. We choose F110W instead of F125W because the F110W -F160W color has a wider wavelength separation. (D) Observation: Exposure time We will take dithered images with 1000 s (two dithers) and 1500 s (three dithers) exposure times per epoch for F160W and F110W, respectively. The configuration of F160W observations will be the same as existing data, which provides high enough SNR for Miras with P>350 d based on our preliminary analysis. The F110W exposure will yield SNRs of >~10 (depends on the target) and ~85 (for NGC 2525) per epoch for 400~d and 1000 d O-rich Miras, respectively, based on the HST Exposure Time Calculator (ETC) and a J-H color of ~0.8 mag (Yuan et al. 2017). After combining all the epochs, the F110W SNRs will be even higher and deep enough for O-rich Miras in all the targets. A 16250( 12) - 07-Oct-2021 17:14:28 - [ 3] subset of the C-rich Miras will have F110W SNRs lower than the detection limit; however, even non-detection in F110W is equally useful for the C- and O-rich Mira classification as they provide color limit measurements. We note that the designed F160W and F110W exposures fit well in one HST orbit per epoch. (E) Observation: Sampling pattern For NGC 2525, we plan to schedule 4 widely-spaced epochs across Cycle 28 to sample the unmeasured phases of long-period Miras and extend the observation baseline to 1300 days. Gaps between epochs are >100 days, which corresponds to >~0.1 in phase and cause no aliases for the period range of interest. With 4 measurements we will be able to correct the random-phased F110W Mira measurements to their mean intensities using the F160W light curves. Random-phase magnitudes would lead to not only larger scatter in the PLR, but also a systematic bias compared to intensity mean ("log average"). Assuming negligible phase lags between the J and H light curves, we have 2 degrees of freedom for the phase correction (free parameters include the mean F110W magnitude and F110W amplitude). Considering the uncertainties in F110W photometry and F160W-based periods & phases, fewer degrees of freedom would limit the accuracy of the F110W-band phase correction. For NGC 1559, NGC 5643, and NGC 5861 we plan to schedule 3 epochs separated by 350/3=120 d to sample the Mira colors at 3 different phases for typical ~350 d Miras. Summary of observations We designed a detailed observation strategy to study the long-period Miras in NGC 2525 and calibrate Ho with short-period Miras in 4 SN Ia hosts. We plan to acquire F160W and F110W images to phase the long-period Miras in NGC 2525, and measure the NIR colors in all 4 galaxies. We have done preliminary analysis and ETC calculations and determined 1000 s and 1500 s exposure times in F160W and F110W, respectively, which assure sufficient SNR and yet best match the existing image depth. The proposed observations will cost 4+3x3=13 orbits in total. Impact of reduced-gyro operations The designed observations will be negatively impacted by the potential reduced-gyro operations. Our observations are time-critical, requiring a cadence spanning several months. Due to the significant loss of field of regards at specific dates, it will be more difficult to schedule our observations. We may need to increase our tolerance of between-orbit gaps in order to fit the limited time windows under reduced-gyro operations. As a result, the long-period Miras may be less effectively sampled. The two-minute increase in target acquisition time under reduced-gyro operations will slightly reduce the exposure time of our targets, but its effect is marginal compared to the schedule difficulties. ------------------------------------------------------------------------------------ 16250( 12) -
