CCAPP Summer Seminar
"Counting Giants"
Johnny Greco (OSU Physics)
The new generation of wide-field imaging surveys will
uncover thousands of diffuse dwarf galaxy candidates beyond the Local
Group. Reliable distances will be required to confirm the nature of
these candidates and to study their numbers and physical properties as
a function of environment. Surface brightness fluctuations (SBF) offer
a powerful method for measuring galaxy distances using imaging data
alone, making it one of the most promising tools for finding and
studying dwarf galaxies with current and future wide-field surveys. I
will provide an introduction to the SBF method and present results
from my ongoing work to simulate SBF in detail and implement it in
practice using high-resolution ground-based imaging data.
