SBF distances to Leo and Virgo using the HST ?
We have used archive HST WFPC2 data for three elliptical galaxies (NGC 3379 in the Leo I group, and NGC 4472 and NGC 4406 in the Virgo cluster) to determine their distances using the Surface Brightness Fluctuation (SBF) method as described by Tonry and Schneider (1988). A comparison of the HST results with the SBF distance moduli of Ciardullo et al (1993) shows significant disagreement and sugg...
متن کاملThe SBF survey of galaxy distances - J.L. Tonry
for 1.0 < (V I) < 1.3. This agrees well with theoretical estimates from stellar population models. Comparisons between SBF distances and a variety of other estimators, including Cepheid variable stars, the Planetary Nebula Luminosity Function (PNLF), Tully-Fisher (TF), Dn , SNII, and SNIa, indicate that the calibration of SBF is universally valid and that SBF error estimates are accurate. The z...
متن کاملThe ACS Virgo Cluster Survey V: SBF Calibration for Giant and Dwarf Early-type Galaxies
As part of the Advanced Camera for Survey (ACS) Virgo Cluster Survey, we have measured Surface Brightness Fluctuations (SBF) in a sample of 100 earlytype Virgo galaxies. Distances derived from these measurements are needed to explore the three-dimensional structure of the Virgo Cluster, study the intrinsic parameters of globular clusters associated with the program galaxies, and compare with th...
متن کاملDistances from Stellar Kinematics for Peculiar Virgo Cluster Spiral Galaxies
We present distance estimates for eleven peculiar Virgo cluster spiral galaxies based on measurements of the stellar kinematics of their central 2 kpc. Stellar circular velocities were obtained using two-integral dynamical models. Distances were obtained by comparing, at each radius, the stellar circular velocities with synthetic Hα rotation curves derived from NIR Tully-Fisher relations. The r...
متن کاملOn a systematic bias in SBF-based distances due to gravitational microlensing
The effect of gravitational microlensing on the determination of extragalactic distances using surface brightness fluctuations (SBF) technique is considered and a method to calculate SBF amplitudes in presence of microlensing is presented. With a simple approximation for the magnification power spectrum at low optical depth the correction to the SBF-based luminosity distance is calculated. The ...
