Testing the Surface Brightness Fluctuation Method on Dwarf Galaxies in the COSMOS Field [PDF]

open access: yes, 2023
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.

Yonsei Evolutionary Population Synthesis (YEPS) Model. III. Surface Brightness Fluctuation of Normal and Helium-enhanced Simple Stellar Populations [PDF]

open access: yesAstrophysical Journal Supplement Series, 2020
We present an evolutionary population synthesis model of the surface brightness fluctuation (SBF) for normal and He-enriched simple stellar populations (SSPs).

Surface-brightness fluctuations in stellar populations [PDF]

open access: yesProceedings of the International Astronomical Union, 2006
Abstract 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 filters. The IAC-star code is used together with two Padua and the Teramo stellar evolution libraries.

The Next Generation Virgo Cluster Survey (NGVS). XVIII. Measurement and Calibration of Surface Brightness Fluctuation Distances for Bright Galaxies in Virgo (and Beyond) [PDF]

open access: yes, 2018
We describe a program to measure surface brightness fluctuation (SBF) distances to galaxies observed in the Next Generation Virgo Cluster Survey (NGVS), a photometric imaging survey covering 104 deg2 of the Virgo cluster in the u*, g, i, and z bandpasses

Infrared Surface Brightness Fluctuations of Magellanic Star Clusters [PDF]

open access: yesThe Astrophysical Journal, 2004
We present surface brightness fluctuations (SBFs) in the near--IR for 191 Magellanic star clusters available in the Second Incremental and All Sky Data releases of the Two Micron All Sky Survey (2MASS), and compare them with SBFs of Fornax Cluster galaxies and with predictions from stellar population models. Our goals are twofold.

The Next Generation Virgo Cluster Survey (NGVS). III. A Catalog of Surface Brightness Fluctuation Distances and the Three-dimensional Distribution of Galaxies in the Virgo Cluster [PDF]

open access: yesAstrophysical Journal
The surface brightness fluctuation (SBF) method is a robust and efficient way of measuring distances to galaxies containing evolved stellar populations. Although many recent applications of the method have used space-based imaging, SBF remains a powerful

MEASURING INFRARED SURFACE BRIGHTNESS FLUCTUATION DISTANCES WITH HST WFC3: CALIBRATION AND ADVICE [PDF]

open access: yes, 2015
We present new calibrations of the near-infrared (near-IR) surface brightness fluctuation (SBF) distance method for the F110W ( J 110 ?> ) and F160W ( H 160 ?> ) bandpasses of the Wide Field Camera 3 Infrared Channel (WFC3/IR) on the Hubble Space ...

Towards gradient detection of surface brightness fluctuations

open access: yes, 2022
Abstract: Surface Brightness Fluctuations (SBF) magnitudes have been proved as a potential tool for the study of composite stellar populations in galaxies. In particular, we focus on the detection of metal-poor secondary components in metal-rich dominated early type galaxies. Our current work consists in studying radial profiles of SBFs, hence we study
