Modified Baryonic Dynamics: two-component cosmological simulations with light sterile neutrinos [PDF]
, 2014 In this article we continue to test cosmological models centred on Modified Newtonian Dynamics (MOND) with light sterile neutrinos, which could in principle be a way to solve the fine-tuning problems of the standard model on galaxy scales while ...

Near-infrared spectroscopy of gamma-ray burst host galaxies at z≳: insights into host galaxy dynamics and interpretations of afterglow absorption spectra [PDF]
, 2011 This paper presents near-infrared echellette spectra of faint galaxies in the fields around GRB 050820A at redshift z= 2.613 and GRB 060418 at z= 1.490.

The local extragalactic velocity field, the local mean mass density, and biased galaxy formation [PDF]
, 1987 The biased galaxy formation picture accounts for the low apparent mass density derived from clustering dynamics by the assumption that the mass per galaxy is unusually low in the regions of high density where clustering has been studied.

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.

Galaxy Dynamics: Secular Evolution and Accretion [PDF]
Proceedings of the International Astronomical Union, 2010 Recent results are reviewed on galaxy dynamics, bar evolution, destruction and re-formation, cold gas accretion, gas radial flows and AGN fueling, minor mergers. Some problems of galaxy evolution are discussed in particular, exchange of angular momentum,

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.
