Measuring Infrared Surface Brightness Fluctuation Distances With Hst Wfc3: Calibration And Advice, Joseph Jensen
Measuring Infrared Surface Brightness Fluctuation Distances With Hst Wfc3: Calibration And Advice, Joseph Jensen
Joseph Jensen
We present new calibrations of the near-infrared (near-IR) surface brightness fluctuation (SBF) distance method
for the F110W (J110) and F160W (H160) bandpasses of the Wide Field Camera 3 Infrared Channel (WFC3/IR) on
the Hubble Space Telescope. The calibrations are based on data for 16 early-type galaxies in the Virgo and Fornax
clusters observed with WFC3/IR and are provided as functions of both the optical (g475-z850 ) and near-infrared
(J -H ) colors. The scatter about the linear calibration relations for the …
