Inferences from Surface Brightness Fluctuations of Zwicky 3146 via the Sunyaev–Zel’dovich Effect and X-Ray Observations [PDF]
The Astrophysical Journal, 2023 The galaxy cluster Zwicky 3146 is a sloshing cool-core cluster at z = 0.291 that in Sunyaev–Zel’dovich (SZ) imaging does not appear to exhibit significant pressure substructure in the intracluster medium.

New Near-Infrared Surface Brightness Fluctuation Models [PDF]
Mon.Not.Roy.Astron.Soc.362:1208,2005, 2005 We present new theoretical models for surface brightness fluctuations in the near-infrared. We show the time evolution of near-infrared brightness fluctuation properties over large age and metallicity ranges, i.e., from 12 Myr to 16 Gyr, and from Z/Zsun=1/50 to Z/Zsun=2.5, for single age, single metallicity stellar populations.

Anomalous surface brightness fluctuations in NGC 4489 [PDF]
Astronomy & Astrophysics, 2001 Anomalously high K-band surface brightness fluctuations (SBF) have been reported in NGC 4489 by Pahre & Mould (1994), Jensen et al. (1996) and Jensen et al. (1998). However, these conclusions were uncertain because of relatively low signal-to-noise data. New high signal-to-noise data for NGC 4489 have been obtained at the NOAO/KPNO 2.1m and the ESO/

The Infrared Surface Brightness Fluctuation Hubble Constant [PDF]
The Astrophysical Journal, 2001 We measured infrared surface brightness fluctuation (SBF) distances to an isotropically-distributed sample of 16 distant galaxies with redshifts reaching 10,000 km/s using the near-IR camera and multi-object spectrometer (NICMOS) on the Hubble Space Telescope (HST).

Surface Brightness Fluctuations and the Stellar Population in Elliptical Galaxies [PDF]
Symposium - International Astronomical Union, 1995 The Surface Brightness Fluctuation (SBF) method introduced by Tonry & Schneider (1988) is known as a distance indicator. However, we focus on another aspect. Our aim is to obtain new information on the stellar population that constitutes an elliptical galaxy by comparing radial gradients in SBF magnitudes with traditional broad-band colours.

Distances from Surface Brightness Fluctuations [PDF]
, 1998 The practice of measuring galaxy distances from their spatial fluctuations in surface brightness is now a decade old. While several past articles have included some review material, this is the first intended as a comprehensive review of the surface brightness fluctuation (SBF) method.

VLT Deep I-band Surface Brightness Fluctuations of IC 4296 [PDF]
Astron.Astrophys. 361 (2000) 68, 2000 From theoretical predictions, the introduction of 8-m class telescopes permits one to extend Surface Brightness Fluctuations measurements from the ground to ~7000 km/s, with a precision that is comparable to current space-based measurements. We have measured I--band SBF in IC 4296 in Abell 3565 cz~3630 km/s with the ESO Very Large Telescope.

Surface brightness fluctuation distances for nearby dwarf elliptical galaxies [PDF]
Astronomy & Astrophysics, 2001 We obtained B and R-band CCD images for the dwarf elliptical (dE) galaxies DDO44, UGC4998, KK98_77, DDO71, DDO113, and UGC7356 at the NOT. Using Fourier analysis technique we measure stellar R-band surface brightness fluctuations (SBFs) and magnitudes in 29 different fields of the galaxies.
