Surface brightness fluctuation spectra to constrain stellar population properties [PDF]
Monthly 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 Astrophysical Journal, 2023 We compare infrared surface brightness fluctuation (IR SBF) distances measured in galaxies that have hosted type Ia supernovae (SNe Ia) to distances estimated from SNe Ia light-curve fits.

A Dynamic Threshold Cloud Detecting Approach based on the Brightness Temperature from FY-2 VISSR Data [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015 The traditional statistical methods and radiation transfer theory methods for cloud detecting have a high adaptability just only in those areas with a uniform surface coverage and noncomplex terrain.

Optical Surface Brightness Fluctuations of Shell Galaxies toward 100 Mpc [PDF]
The Astrophysical Journal, 2008 We measure F814W Surface Brightness Fluctuations (SBF) for a sample of distant shell galaxies with radial velocities ranging from 4000 to 8000 km/s. The distance at galaxies is then evaluated by using the SBF method. For this purpose, theoretical SBF magnitudes for the ACS@HST filters are computed for single burst stellar populations covering a wide ...

Measuring Distances Using Infrared Surface Brightness Fluctuations [PDF]
The Astrophysical Journal, 1998 Surface brightness fluctuations (SBFs) are much brighter in the IR than they are at optical wavelengths, making it possible to measure greater distances using IR SBFs. We report new K' (2.1 micron) SBF measurements of 9 galaxies in the Fornax and Eridanus clusters using a 1024^2-pixel HgCdTe array.

Towards gradient detection of surface brightness fluctuations
, 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

The Hubble Constant from Infrared Surface Brightness Fluctuation Distances*
The Astrophysical 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).
