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.

The surface-brightness fluctuation distance of NGC 5128

The Astronomical 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.

The Infrared Surface Brightness Fluctuation Hubble Constant [PDF]

The Astrophysical Journal, 2000
We measured infrared surface brightness fluctuation (SBF) distances to an isotropically distributed sample of 16 distant galaxies with redshifts reaching 10,000 km s-1 using the near-IR camera and multiobject spectrometer (NICMOS) on the Hubble Space ...

The TRGB−SBF Project. III. Refining the HST Surface Brightness Fluctuation Distance Scale Calibration with JWST

The Astrophysical Journal
The TRGB−SBF Project team is developing an independent distance ladder using a geometrical calibration of the tip of the red giant branch (TRGB) method in elliptical galaxies that can, in turn, be used to set the surface brightness fluctuation (SBF ...

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

Monthly 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

Carnegie Supernova Project I and II: Measurements of H 0 Using Cepheid, Tip of the Red Giant Branch, and Surface Brightness Fluctuation Distance Calibration to Type Ia Supernovae

The Astrophysical Journal
We present an analysis of Type Ia supernovae (SNe Ia) from the Carnegie Supernova Project I and II and extend the Hubble diagram from optical to near-infrared wavelengths ( uBgVriYJH ).

On the Nature of X-ray Surface Brightness Fluctuations in M87 [PDF]

The Astrophysical Journal, 2015
X-ray images of galaxy clusters and gas-rich elliptical galaxies show a wealth of small-scale features which reflect fluctuations in density and/or temperature of the intra-cluster medium.

Distance Measurements and Stellar Population Properties via Surface Brightness Fluctuations [PDF]

Publications of the Astronomical Society of Australia, 2012

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

, 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.

Surface-brightness fluctuations in stellar populations [PDF]

Astronomy & 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.
