The Metal Content of Resolved Galaxies
Lidia N. Makarova, Denis G. Purytin, R. Brent Tully +1
We present a homogeneous metallicity analysis of old stellar populations in Local Volume (LV) galaxies using data from the CMDs/TRGB catalog of the Extragalactic Distance Database…
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 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…
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…
