Abstract:
We present year-long, near-infrared Hubble Space Telescope (HST) WFC3
observations used to search for Mira variables in NGC 1559, the host
galaxy of the Type Ia supernova (SN Ia) SN 2005df. This is the first
dedicated search for Miras, highly evolved low-mass stars, in an SNIa
host, and subsequently the first calibration of the SN Ia luminosity
using Miras in a role historically played by Cepheids. We identify a
sample of 115 O-rich Miras with P<400days based on their light-curve
properties. We find that the scatter in the Mira period-luminosity
relation (PLR) is comparable to Cepheid PLRs seen in SN Ia host
galaxies. Using a sample of O-rich Miras discovered in NGC 4258 with
HSTF160W and its maser distance, we measure a distance modulus for
NGC1559 of µ1559=31.41±0.050(statistical)±0.060(systematic)mag.
Based on the light curve of the normal, well-observed, low-reddening
SN 2005df, we obtain a measurement of the fiducial SN Ia absolute
magnitude of MB0=-19.27±0.13mag. With the Hubble diagram of SNe
Ia we find H0=72.7±4.6km/s/Mpc. Combining the calibration from the
NGC 4258 megamaser and the Large Magellanic Cloud detached eclipsing
binaries gives a best value of H0=73.3±4.0km/s/Mpc. This result is
within 1σ of the Hubble constant derived using Cepheids and
multiple calibrating SNe Ia. This is the first of four expected
calibrations of the SN Ia luminosity from Miras that should reduce the
error in H0 via Miras to ∼3%. In light of the present Hubble tension
and JWST, Miras have utility in the extragalactic distance scale to
check Cepheid distances or calibrate nearby SNe in early-type host
galaxies that would be unlikely targets for Cepheid searches.
Description:
This study uses 10 epochs of HST WFC3/IR F160W data (GO-15145;
PI Riess), with an exposure time of 1006s for each epoch.
The epochs have an approximately monthly cadence between
2017 September 8 and 2018 September 11, with a field of view centered
at RAJ2000=04:17:37 and DEJ2000=-62:47:00.
To put our observations on the same zero-point as H18
(Huang+, 2018, J/ApJ/857/67), which we adopt for an absolute
calibration of distance, we use the same HST WFC3 IR photometric
zero-point for a 0.4"-radius aperture. In Vega magnitudes, the F160W
zero-point is 24.5037mag. See Section 2.2.
