Abstract:
We present a gravitational-lensing model of MACS J1149.5+2223 using
ultra-deep Hubble Frontier Fields imaging data and spectroscopic
redshifts from HST grism and Very Large Telescope (VLT)/MUSE
spectroscopic data. We create total mass maps using 38 multiple images
(13 sources) and 608 weak-lensing galaxies, as well as 100 multiple
images of 31 star-forming regions in the galaxy that hosts supernova
Refsdal. We find good agreement with a range of recent models within
the HST field of view. We present a map of the ratio of projected
stellar mass to total mass (f*) and find that the stellar mass
fraction for this cluster peaks on the primary BCG. Averaging within a
radius of 0.3Mpc, we obtain a value of <f*≥0.012-0.003+0.004,
consistent with other recent results for this ratio in cluster
environments, though with a large global error (up to
δf*=0.005) primarily due to the choice of IMF. We compare
values of f* and measures of star formation efficiency for this
cluster to other Hubble Frontier Fields clusters studied in the
literature, finding that MACS1149 has a higher stellar mass fraction
than these other clusters but a star formation efficiency typical of
massive clusters.
Description:
Original spectroscopy for MACS J1149.5+2223 was obtained from the
Grism Lens-Amplified Survey from Space (GLASS;
Schmidt+ 2014ApJ...782L..36S 2014ApJ...782L..36S ; Treu+ 2015, J/ApJ/812/114) which was
initiated to study highly magnified high-redshift objects. The GLASS
collaboration obtained 14 Hubble Space Telescope (HST) orbits per
cluster, with the Wide Field Camera 3 (WFC3) IR G102 (10 orbits) and
G141 (4 orbits) grisms (field of view 123"x136"). The average spectral
resolution was R∼130 for the G141 grism and R∼210 for the G102 grism.
Overall, the spectra covered a continuous wavelength range of
0.81-1.69um. Deep HST G141 data were taken as part of the SN Refsdal
follow-up campaign (HST-GO-14041; PI: Kelly), adding another 30 orbits
of G141 spectra.
In addition to the HST spectroscopy, spectroscopic data were taken
with the Very Large Telescope (VLT)/Multi Unit Spectroscopic Explorer
(MUSE). Observations were taken in the wavelength range 480-930nm,
with a total integration time of 4.8hr. The field of view was 1'x1',
with an average spectral resolution of R∼3000.
See Section 2.1.
As part of the HFF initiative (HST-GO 13504; PI: J. Lotz), MACS1149
was observed in seven filters: three advanced cameras for surveys
(ACS)/optical filters (F435W, F606W, and F814W) and four WFC3/IR
filters (F105W, F125W, F140W, and F160W). These data were taken
between 2014 November and 2015 June (141 orbits) and supplemented by
additional WFC3/NIR data from the SN Refsdal follow-up campaign
(20 orbits; PI: Rodney, HST-GO 13790; PI: Kelly, HST-GO 14041). We use
both epochs of the public release data products from the HFF team.
Further supplementary data were obtained from the CLASH program.
We use deep Spitzer/Infrared Array Camera (IRAC) images in combination
with the HST images to improve stellar mass and photometric redshift
measurements of cluster members and background galaxies.
