The deep SARAO MeerKAT Galactic Plane Survey (SMGPS) covers the whole southern Milky Way along a narrow strip of Δ𝑏 ∼ 3◦. While primarily aimed at exploring the inner Galaxy, the SMGPS provides a unique opportunity to trace the large-scale distribution of galaxies from their redshifted HI-line emission. Thanks to the excellent resolution and sensitivity of the SMGPS (rms = 0.30-0.60 mJy/beam),...

The Vela supercluster (VSCL) is an extended and massive supercluster located at l ~ 275°±15°; |b| < 10°, and cz ~ 18000 km s-1. Its location is of particular interest in view of its proximity to the apex, where residual bulk flows suggest a considerable surplus of mass. However, a major fraction of its extent has little data below Galactic latitudes of |b| < 7–8° because of the obscuration by...

A representative sample of nearby galaxies is the basis for solving various problems of extragalactic astronomy, a source of important information about galaxies, their formation and evolution, distribution in space and the formation of the large-scale structure of the Universe. The Local Volume, a sphere of about 10 Mpc radius, gives us a unique opportunity to observe a large number of dwarf...

We analyzed the velocity field near the Local Group outside the virial zones of Milky Way and Andromeda galaxies on scales from 400 to 1400 kpc. The Hubble flow model allows us to estimate the total mass of the Local Group of $M_\mathrm{LG} = (2.42 \pm 0.12) \times 10^{12}$ $M_\odot$, which is in excellent agreement with the sum of the individual masses of Our Galaxy and Andromeda inside their...
