New optical velocities for local galaxy candidates
Maksim Chazov, Igor Karachentsev, Serafim Kaisin
The authors measured radial velocities for 46 nearby galaxy candidates with the 6‑m BTA telescope, identifying new probable satellite galaxies of several Local Volume hosts and est…
Optical identification of the FASHI sources: toward the extended Local Volume
Aleksandra E. Nazarova, Dmitry I. Makarov, Igor D. Karachentsev +3
We extracted a list of 662 nearby (within Mpc) HI-detection sources from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) All Sky HI Survey (FASHI) and mad…
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…
100 Proof: HI Observations of 100 Nearby Dwarf Galaxies with the 100-meter Green Bank Telescope
Aleksandra E. Nazarova, John M. Cannon, Igor D. Karachentsev +4
We describe the results of observations with the 100m Robert C. Byrd Green Bank Telescope (GBT) in the HI line of 105 nearby dwarf galaxies, 60 of which were discovered recently in…
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…
