The ACS Virgo Cluster Survey. IV. Data Reduction Procedures for Surface Brightness Fluctuation Measurements with the Advanced Camera for Surveys [PDF]
, 2005 The Advanced Camera for Surveys (ACS) Virgo Cluster Survey is a large program to image 100 early-type Virgo galaxies using the F475W and F850LP bandpasses of the Wide Field Channel of the ACS instrument on the Hubble Space Telescope (HST). The scientific

Detection of Surface Brightness Fluctuations in Elliptical Galaxies imaged with the Advanced Camera for Surveys. B- and I-band measurements [PDF]
, 2007 Taking advantage of the exceptional capabilities of ACS on board of HST, we derive Surface Brightness Fluctuation (SBF) measurements in the B and I bands from images of six elliptical galaxies with $1500 \leq cz \leq 3500$. Given the low S/N ratio of the

Surface Brightness Fluctuations: a theoretical point of view
, 2002 We present new theoretical evaluations of optical and near-IR Surface Brightness Fluctuations (SBF) magnitudes for single-burst stellar populations in the age range t=5-15 Gyr and metallicity from $Z_{\sun}/200$ to $2Z_{\sun}$. Our theoretical predictions can be successfully used to derive reliable distance evaluations. They also appear to be a new and

Large-scale distributions of mid- and far-infrared emission from the center to the halo of M82 revealed with AKARI [PDF]
, 2002 The edge-on starburst galaxy M82 exhibits complicated distributions of gaseous materials in its halo, which include ionized superwinds driven by nuclear starbursts, neutral materials entrained by the superwinds, and large-scale neutral streamers probably

The First SNAP Surface Brightness Fluctuation Distances [PDF]
, 2023 We have successfully acquired F110W (J-band) images of 68 massive elliptical galaxies inclusters and groups out to 80 Mpc by taking advantage of the efficient Hubble Space Telescope SNAP observing mode. We used the Surface Brightness Fluctuation (SBF) technique to measure distances to 44 of the galaxies so far with a typical uncertainty of ~5 ...

The Distance to the Coma Cluster from Surface Brightness Fluctuations
, 1997 We report on the first determination of the distance to the Coma Cluster based on surface brightness fluctuation (SBF) measurements obtained from Hubble Space Telescope WFPC2 observations of the bright E0 galaxy NGC 4881 in the Coma Cluster and ground ...

Quantifying protein densities on cell membranes using super-resolution optical fluctuation imaging [PDF]
, 2017 Surface molecules, distributed in diverse patterns and clusters on cell membranes, influence vital functions of living cells. It is therefore important to understand their molecular surface organisation under different physiological and pathological ...

Surface brightness fluctuation distances for dwarf elliptical galaxies in the Fornax cluster [PDF]
, 2001 We have obtained deep B and R-band CCD images of eight dwarf elliptical (dE) galaxies in the Fornax cluster using the FORS1 instrument at the VLT in service mode under excellent atmospheric conditions.
