Abstract:
Using the M31 PAndromeda Cepheid sample and the HST PHAT data we
obtain the largest Cepheid sample in M31 with HST data in four bands.
For our analysis we consider three samples: A very homogeneous sample
of Cepheids based on the PAndromeda data, the mean magnitude corrected
PAndromeda sample and a sample complementing the PAndromeda sample
with Cepheids from literature. The latter results in the largest
catalog with 522 fundamental mode (FM) Cepheids and 102 first overtone
(FO) Cepheids with F160W and F110W data and 559 FM Cepheids and 111 FO
Cepheids with F814W and F475W data. The obtained dispersion of the
Period-Luminosity relations (PLRs) is very small (e.g. 0.138mag in
the F160W sample I PLR). We find no broken slope in the PLRs when
analyzing our entire sample, but we do identify a subsample of
Cepheids that causes the broken slope. However, this effect only shows
when the number of this Cepheid type makes up a significant fraction
of the total sample. We also analyze the sample selection effect on
the Hubble constant.
Description:
Fit parameters of the PAndromeda Cepheid sample in M31 in the F475W,
F814W, F110W and F160W HST bands.
