| Abstract: |
The method of measuring the variations in surface brightness of an
early-type galaxy, known as surface brightness fluctuations (SBF),
has been developed as an excellent tool for measuring distances and for
probing the ages and metallicities of red giant branch stars in old,
metal-rich populations.
SBF is an extragalactic distance technique with ∼5% precision that
can be used out to 100 Mpc without having to resolve individual stars or
monitor them for long periods of time. The SBF method bridges the gap between
resolved stellar population studies and the extragalactic distance scale,
and therefore touches on many of the topics discussed in this conference
recognizing the contributions of Jeremy Mould. This paper includes some
recent applications of the technique and some prospects for future IR SBF
observations with JWST and next-generation ground-based telescopes. |
