Internally-driven warps in disc galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 Any perturbation to a disc galaxy that creates a misalignment between the planes of the inner and outer disc, will excite a slowly evolving bending wave in the outer disc. The torque from the stiff inner disc drives a retrograde, leading-spiral bending wave that grows in amplitude as it propagates outward over a period of several Gyr.

Entropy and Mass Distribution in Disc Galaxies [PDF]
Galaxies, 2020 The relaxed motion of stars and gas in galactic discs is well approximated by a rotational velocity that is a function of radial position only, implying that individual components have lost any information about their prior states.

Potential impact of the Sagittarius dwarf galaxy on the formation of young O-rich stars. [PDF]
Nat CommunThe Milky Way underwent significant transformations in its early history, characterised by violent mergers and satellite galaxy accretion. However, recent observations reveal notable star formation events over the past 4 Gyr, likely triggered by ...

Dark matter mass loss in galaxy flybys: dependence on impact parameter [PDF]
Serbian Astronomical Journal, 2022 Galaxy flybys, interactions where two independent halos inter-penetrate but detach at a later time and do not merge, occur frequently at lower redshifts.

Formation of Transitional cE/UCD Galaxies through Massive/Dwarf Disc Galaxy Mergers
Galaxies, 2023 The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky Way type were studied in detail. The remnant of such interaction after numerous crossings of the satellite through the disc of the main galaxy was a compact ...

Formation of Major Types of Galaxies Based on the Energy Circulation Theory
Reports in Advances of Physical Sciences, 2022 The standard cosmology can answer almost nothing about how the structure of a galaxy is formed. It expects a supermassive black hole at the center and dark matter in the halo to explain the circulation of stars and its velocity.
