Euclid: Calibrating distances from surface brightness fluctuations with Early Release Observations of the Fornax cluster
R. Habas, M. Cantiello, G. Riccio +169
Surface brightness fluctuations (SBF), the pixel-to-pixel variations in flux that arise from the statistical distribution of stars in galaxy images, provide a powerful tool to meas…

The TRGB-SBF Project. II. Resolving the Virgo Cluster with JWST
Gagandeep S. Anand, R. Brent Tully, Yotam Cohen +9
The Virgo Cluster is the nearest substantial cluster of galaxies to the Milky Way and a cornerstone of the extragalactic distance scale. Here, we present JWST/NIRCam observations t…
