Abstract:
The giant spiral galaxy M101 is host to the nearest recent Type Ia
supernova (SN 2011fe) and thus has been extensively monitored in the
near-infrared to study the late-time light curve of the SN. Leveraging
this existing baseline of observations, we derive the first Mira-based
distance to M101 by discovering and classifying a sample of 211 Miras
with periods ranging from 240-400 days in the SN field. Combined with
new Hubble Space Telescope (HST) WFC3/IR channel observations, our
data set totals 11 epochs of F110W (HST YJ) and 13 epochs of F160W
(HST H) data spanning ∼2900 days. We adopt absolute calibrations of
the Mira period-luminosity relation based on geometric distances to
the Large Magellanic Cloud and the water megamaser host galaxy NGC
4258, and find µM101=29.10±0.06mag. This distance is in
1σ agreement with most other recent Cepheid and tip of the red
giant branch distance measurements to M101. Including the previous
Mira SN Ia host, NGC 1559, and SN 2005df, we determine the fiducial SN
Ia peak luminosity, MB0=-19.27±0.09mag. With the Hubble diagram
of supernovae Ia, we derive H0=72.37±2.97km/s/Mpc, a 4.1%
measurement of H0 using Miras. We find excellent agreement with recent
Cepheid distance ladder measurements of H0 and confirm previous
indications that the local universe value of H0 is higher than the
early universe value at ∼95% confidence. Currently, the Mira-based H0
measurement is still dominated by the statistical uncertainty in the
SN Ia peak magnitude.
Description:
The field that we targeted and the locations of the Miras discovered
in the galaxy using the selection criteria from Section 3 are shown in
Figure 1. All HST observations, spanning 2014-Oct-09 to 2022-Aug-19
are analyzed in this paper. The full data set can be accessed at
10.17909/z80p-1q97.
We use archival observations of the galaxy acquired in four separate
proposals (GO-13737, PI: Shappee; GO-13824, PI: Kerzendorf; GO-14166,
PI: Shappee; and GO-14678, PI: Shappee) in 2014-2017 using the
infrared (IR) channel of the Wide Field Camera 3 (WFC3) instrument on
board HST in two filters: F110W and F160W (the HST wide YJ and wide H
filters, respectively). All of the observations were centered on or
near the location of SN 2011fe (RAJ200=14:03:05.711,DEJ2000=+54:16:25.22).
In addition, we acquired five new epochs of HST WFC3/IR F110W and
F160W imaging (GO-16744, PI: Huang) from 2021 December to 2022 August.
Combined with the archival observations, the total baseline is 2871days.
