Measuring Distances Using Infrared Surface Brightness Fluctuations
Measuring Distances Using Infrared Surface Brightness Fluctuations
Surface brightness fluctuations (SBFs) are much brighter in the infrared than they are at optical wavelengths, making it possible to measure greater distances using IR SBFs. We report new K' (2.1 μm) SBF measurements of nine galaxies in the Fornax and Eridanus clusters using a 10242 pixel HgCdTe array. We …
