X-Ray surface brightness and gas density fluctuations in the Coma cluster [PDF]
MNRAS, 2012, vol. 421, 1123-1135, 2011 X-ray surface brightness fluctuations in the core ($650 \times 650$ kpc) region of the Coma cluster observed with XMM-Newton and Chandra are analyzed using a 2D power spectrum approach. The resulting 2D spectra are converted to 3D power spectra of gas density fluctuations.

Surface Brightness Fluctuations of Fornax Cluster Galaxies: Calibration of Infrared Surface Brightness Fluctuations and Evidence for Recent Star Formation [PDF]
The Astrophysical Journal, 2002 We have measured K-band surface brightness fluctuations (SBFs) of 19 early-type galaxies in the Fornax cluster. Combining our results with published data, we find the absolute SBF magnitude Mbar_K = (-5.84)+(3.6)*[(V-I)-1.15]. The intrinsic cosmic scatter of Mbar_K appears to be larger than that of I-band SBFs.

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

Cosmic distances from surface brightness fluctuations [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractHigh spatial-resolution measurements of surface brightness fluctuations (SBFs) with the Hubble Space Telescope (HST) provide the most precise distances available to early-type galaxies beyond the Local Group. The observable SBF magnitude in a given bandpass is a basic property of any stellar system, corresponding to a ratio of the first and ...

Surface Brightness Fluctuations: A Case for Extremely Large Telescopes [PDF]
, 2003 The Surface Brightness Fluctuations (SBF) Method for distance determinations of elliptical galaxies is been modeled in order to investigate the effect of the Point Spread Function (PSF). We developed a method to simulate observations of SBF of galaxies having various properties and located at different distances.

Surface brightness fluctuations, tracers of stellar mass-loss? [PDF]
Proceedings of the International Astronomical Union, 2009 AbstractWe present optical and IR integrated colors and SBF magnitudes, computed from stellar population synthesis models that include emission from the dusty envelopes surrounding mass-loosing TP-AGB stars. We explore the effects of varying the mass-loss rate by one order of magnitude around the fiducial value, modifying accordingly both the stellar ...

Surface brightness fluctuations and the distance to the Virgo Cluster
The Astrophysical Journal, 1989 Preliminary results from a project to measure the fluxes of giant stars in M32, NGC 3379, and five Virgo Cluster galaxies are presented. Since the Virgo Cluster galaxies are approximately equidistant, variations in observed fluctuation amplitude from galaxy to galaxy can be ascribed to variations in absolute luminosity of the giant stars in the ...
