WISE Photometry of Galaxies within 10 Mpc
R. Brent Tully, Ehsan Kourkchi, James D. Neill
For photometry of galaxies in the infrared that extend to very low surface brightnesses, it is necessary to observe with telescopes in space. WISE and NEOWISE provide sensitive all…
Deep Hα survey of the Coma cluster: The Catalog
Sarah E. Kay, Ehsan Kourkchi, A. Molaeinezhad +4
We present a deep wide-field narrow-band imaging survey of the local rich and dynamically relaxed Coma cluster of galaxies, carried out with the Wide Field Camera at the Isaac Newt…
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…
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…
