New near-infrared surface brightness fluctuation models [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2005
We present new theoretical models for surface brightness fluctuations (SBFs) in the nearinfrared (near-IR). We show the time evolution of near-IR brightness fluctuation properties over large age and metallicity ranges, i.e. from 12 Myr to 16 Gyr and from

A synthesis of data from fundamental plane and surface brightness fluctuation surveys [PDF]

open access: greenMonthly Notices of the Royal Astronomical Society, 2001
We perform a series of comparisons between distance-independent photometric and spectroscopic properties used in the surface brightness fluctuation (SBF) and fundamental plane (FP) methods of early-type galaxy distance estimation. The data are taken from

The Hubble Constant from Infrared Surface Brightness Fluctuation Distances [PDF]

open access: yesThe Astrophysical Journal, 2021
We present a measurement of the Hubble constant H 0 from surface brightness fluctuation (SBF) distances for 63 bright, mainly early-type galaxies out to 100 Mpc observed with the WFC3/IR on the Hubble Space Telescope (HST).

Surface brightness fluctuation spectra to constrain stellar population properties [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
We present a new set of Surface Brightness Fluctuation spectra computed with the E-MILES stellar population synthesis models. The model SBF spectra cover the range 1680-50000 Angstrom at moderately high resolution, all based on extensive empirical ...

New Optical and Near-Infrared Surface Brightness Fluctuation Models. II. Young and Intermediate-Age Stellar Populations [PDF]

open access: bronze, 2005
We present theoretical surface brightness fluctuation (SBF) amplitudes for single-burst stellar populations of young and intermediate age (25 Myr ≤ t ≤ 5 Gyr) and metallicities Z = 0.0003, 0.001, 0.004, 0.008, 0.01, 0.02, and 0.04.

Modelling of surface brightness fluctuation measurements. Methodology, uncertainty, and recommendations [PDF]

open access: yesAstronomy & Astrophysics
The goal of this work is to scrutinise the surface brightness fluctuation (SBF) calculation methodology. We analysed the SBF derivation procedure, measured the accuracy of the fitted SBF under controlled conditions, retrieved the uncertainty ...

The ACS Virgo Cluster Survey. IV. Data Reduction Procedures for Surface Brightness Fluctuation Measurements with the Advanced Camera for Surveys [PDF]

open access: bronze, 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

The Surface Brightness Fluctuation Survey of Galaxy Distances. II. Local and Large‐Scale Flows [PDF]

open access: green, 2000
We present results from the Surface Brightness Fluctuation (SBF) Survey for the distances to 300 early-type galaxies, of which approximately half are ellipticals.
