Anomalous surface brightness fluctuations in NGC 4489 [PDF]
Astronomy & Astrophysics, 2001 Anomalously high K-band surface brightness fluctuations (SBF) have been reported in NGC 4489 by Pahre & Mould (1994), Jensen et al. (1996) and Jensen et al. (1998). However, these conclusions were uncertain because of relatively low signal-to-noise data. New high signal-to-noise data for NGC 4489 have been obtained at the NOAO/KPNO 2.1m and the ESO/

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.

ON THE NATURE OF X-RAY SURFACE BRIGHTNESS FLUCTUATIONS IN M87 [PDF]
The Astrophysical Journal, 2016 ABSTRACT X-ray images of galaxy clusters and gas-rich elliptical galaxies show a wealth of small-scale features that reflect fluctuations in density and/or temperature of the intracluster medium. In this paper we study these fluctuations in M87/Virgo to establish whether sound waves/shocks, bubbles, or uplifted cold gas dominate the ...

Infrared Surface Brightness Fluctuations of Magellanic Star Clusters [PDF]
The 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.

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

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.
