Abstract

We determined H I 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 sources that could correspond to these galaxies. Four of them are probable peripheral satellites of the bright spiral galaxies: NGC 3556, NGC 4258, NGC 4274 and NGC 4490, while others are isolated objects. The considered sample has the following median parameters: a heliocentric velocity of Vh = 542 km s−1, an H I-line width of W50 = 28 km s−1, a hydrogen mass of = 6.83, a stellar mass of = 7.19, and a specific star formation rate of sSFR = −10.17 yr−1.
