Simulations of the dynamics of magnetized jets and cosmic rays in galaxy clusters [PDF]
Monthly notices of the Royal Astronomical Society, 2018 Feedback processes by active galactic nuclei in the centres of galaxy clusters appear to prevent large-scale cooling flows and impede star formation. However, the detailed heating mechanism remains uncertain.

Dark Coincidences: Small-Scale Solutions with Refracted Gravity and MOND
Universe, 2023 General relativity and its Newtonian weak field limit are not sufficient to explain the observed phenomenology in the Universe, from the formation of large-scale structures to the dynamics of galaxies, with the only presence of baryonic matter.

THE ASYMMETRIC DRIFT AND THE ROTATION CURVE OF THE GALAXY
Odessa Astronomical Publications, 2014 Asymmetric drift in the solar neighbourhood is studied by the means of the RAVE data. The asymmetric drift correction is applied to the SDSS data to measure the rotation curve of the Milky Way in the extended solar neighbourhood.

A rumble in the dark: signatures of self-interacting dark matter in supermassive black hole dynamics and galaxy density profiles [PDF]
, 2017 We explore for the first time the effect of self-interacting dark matter (SIDM) on the dark matter (DM) and baryonic distribution in massive galaxies formed in hydrodynamical cosmological simulations, including explicit baryonic physics treatment.

The cosmology dependence of galaxy clustering and lensing from a hybrid N-body–perturbation theory model [PDF]
, 2021 We implement a model for the two-point statistics of biased tracers that combines dark matter dynamics from $N$-body simulations with an analytic Lagrangian bias expansion.

Dynamics of Powerful Radio Galaxies
Galaxies, 2023 Analytical models describing the dynamics of lobed radio sources are essential for interpretation of the tens of millions of radio sources that will be observed by the Square Kilometre Array and pathfinder instruments. We propose that historical models can be grouped into two classes in which the forward expansion of the radio source is driven by ...

A Comparison of Supermassive Black Hole Mass of NGC 4151 Using Different Methods
Passer Journal, 2020 We found a new value of supermassive black hole (SMBH) mass in the middle of type 1 Seyfert, NGC 4151 galaxy. In this Study, the image of NGC 4151 galaxy was deprojected to face-on, using spiral galaxy of face-on, and applied IRAF to calculate the ...
