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

open access: yesMonthly Notices of the Royal Astronomical Society, 2020
ABSTRACT We present a new set of surface brightness fluctuation (SBF) spectra computed with the E-MILES stellar population synthesis models. The model SBF spectra cover the range λλ1680–50 000 at moderately high resolution, all based on extensive empirical stellar libraries.

The Hubble Constant from Infrared Surface Brightness Fluctuation Distances*

open access: yesAstrophysical Journal, 2021
Abstract 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).

The surface-brightness fluctuation distance of NGC 5128

open access: yesAstronomical Journal, 1990
Observations are presented of the surface-brightness fluctuations and photometry of globular clusters in the interacting galaxy NGC 5128 (Centaurus A). It is found that the fluctuation apparent magnitudes are 26.08 and 28.12; the I band magnitude implies that NGC 5128 is 3.1 + or - 0.1 Mpc distant.

Testing the surface brightness fluctuation method on dwarf galaxies in the COSMOS field

open access: yesMonthly Notices of the Royal Astronomical Society, 2023
ABSTRACT Dwarf galaxies are important tracers of small-scale cosmological structure, yet much of our knowledge about these systems comes from the limited sample of dwarf galaxies within the Local Group. To make a comprehensive inventory of dwarf populations in the local Universe, we require effective methods for deriving distance ...

Modelling of surface brightness fluctuation measurements

open access: yesAstronomy and Astrophysics
Aims. 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 associated with the variability of a system that is inherently stochastic, and studied the SBF reliability

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

open access: yesMonthly 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 fluctuations (SBF) and fundamental plane (FP) methods of early-type galaxy distance estimation. The data are taken from two recent surveys: the SBF Survey of Galaxy Distances and the Streaming Motions of Abell Clusters

Surface-brightness fluctuations in stellar populations [PDF]

open access: yesAstronomy & Astrophysics, 2006
Aims. A new theoretical calibration of surface-brightness fluctuations (SBF) for single age, single metallicity stellar populations is presented for the optical and near-IR broad-band filters, as well as for the HST WFPC2 and ACS filters. Methods. The IAC-star code is used. Two Padua and the Teramo stellar evolution libraries have been considered.
