Gaia Data Release 2. Kinematics of globular clusters and dwarf galaxies around the Milky Way
The goal of this paper is to demonstrate the outstanding quality of the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way. We focus here galax...

Radial redistribution of gas connected to a distant galaxy versus galaxy encounter.
We analyze the influence of the perturbation of gravitational field connected to a distant encounter of a spiral with a dwarf galaxy on the radial gas distribution....

ALMA Observations of the Molecular Gas in the Elliptical Galaxy NGC 3557
We present the results of CO interferometric observations of the southern elliptical galaxy NGC 3557 with ALMA. We have detected both the CO(1-0) emission line and a relatively strong continuum at 3mm....

Towards sub-kpc scale kinematics of molecular and ionized gas of star-forming galaxies at z similar to 1
We compare the molecular and ionized gas kinematics of two strongly lensed galaxies at z similar to 1 that lie on the main sequence at this redshift] rotation curves and dispersion profiles of these two galaxies. We find a ...

Stellar streams as gravitational experiments I. The case of Sagittarius
Tidal streams of disrupting dwarf galaxies orbiting around their host galaxy to dark matter on galactic scales is Milgromian dynamics (MOND), and we present here the first ever N-body simulations of the dynamical e...

PHANGS CO Kinematics: Disk Orientations and Rotation Curves at 150 pc Resolution
We present kinematic orientations and high-resolution (150 pc) rotation curves for 67 main-sequence star-forming galaxies surveyed in CO (2-1) emission by PHANGS-ALMA. Our measurements are based on the application of a new fitting m...

Testing MOND gravity in the shell galaxy NGC 3923
Context. The elliptical galaxy NGC3923 is surrounded by numerous stellar shells to observations. The MOdified Newtonian Dynamics (MOND) is a theory that aims to solve the missing mass problem by modifying the laws of classical d...
