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. IV. A Color Calibration of the TRGB in the JWST F090W+F150W Filters
Maksim I. Chazov, Dmitry I. Makarov, R. Brent Tully +7
Observations with JWST in the F090W band provide a powerful tool for determining galaxy distances based on tip of the red giant branch (TRGB) measurements. It is a great convenienc…
The Local Distance Network: a community consensus report on the measurement of the Hubble constant at 1% precision
H0DN Collaboration, Stefano Casertano, Gagandeep Anand +35
The direct, empirical determination of the local value of the Hubble constant (H0) has markedly advanced thanks to improved instrumentation, measurement techniques, and distance es…
FAST-SBF: an automatic procedure for the measurement of Surface Brightness Fluctuations for large sky surveys
Gabriele Riccio, Michele Cantiello, Rebecca Habas +9
The Surface Brightness Fluctuation method is one of the most reliable and efficient ways of measuring distances to galaxies within 100 Mpc. While recent implementations have increa…
The infrared jet of M87 observed with JWST
Jan Röder, Maciek Wielgus, Joseph B. Jensen +2
We present the first JWST+NIRCam images of the giant elliptical active galaxy M87 and its jet at 0.90, 1.50, 2.77 and 3.56 m. We analysed the large-scale jet structure, identif…
The TRGB-SBF Project. III. Refining the HST Surface Brightness Fluctuation Distance Scale Calibration with JWST
Joseph B. Jensen, John P. Blakeslee, Michele Cantiello +5
The TRGB-SBF Project team is developing an independent distance ladder using a geometrical calibration of the tip of the red giant branch (TRGB) method in elliptical galaxies that…
