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…
Problems of cosmology on small scales of the Universe
I. D. Karachentsev
Six challenges for the standard cosmological model CDM are listed, which arise when comparing theoretical predictions with observational data on scales of ~1 Mpc. Different par…
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 Binary Ballet: Mapping Local Expansion Around M81 & M82
Jenny Wagner, David Benisty, Igor D. Karachentsev
This study of the M81 complex and its Hubble flow delivers new and improved Tip of the Red Giant Branch (TRGB)-based distances for nine member galaxies, yielding a total of 58 gala…
Eleven Local Volume dwarf galaxies in the FASHI survey
Aleksandra Nazarova, Dmitry Makarov, Igor Karachentsev +2
We determined HI parameters for eleven nearby late-type dwarf galaxies using FASHI data cubes, despite the fact that the first version of the FASHI catalog does not list any radio…
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…
