Modeling the Mass Distribution and Gravitational Potential of Nearby Disk Galaxies: Implications for the Interstellar Medium Dynamical Equilibrium

open access: yesThe Astrophysical Journal
We characterize stellar, gas, and dark matter mass distributions for 17 nearby massive disk galaxies from the PHANGS sample. This allows us to compute the gravitational potential that vertically confines the interstellar gas and determines its ...

Rotation curves velocities obtained by warm low-density plasma simulating dark halos and “dark matter”

open access: yesAIP Advances
The free electron model with Boltzmann statistics for spherical low-density plasmas is developed further, with asymptotic relations obtaining the density of electrons, mass densities, and the potentials of such plasmas.

A Large-scale Ring Galaxy at z = 2.2 Revealed by JWST/NIRCam: Kinematic Observations and Analytical Modelling

open access: yesThe Astrophysical Journal
A unique galaxy at z = 2.2, zC406690, has a striking clumpy large-scale ring structure that persists from rest-frame UV to near-infrared, yet has an ordered rotation and lies on the star formation main sequence.

The Impact of Bar-induced Noncircular Motions on the Measurement of Galactic Rotation Curves

open access: yesThe Astrophysical Journal
We study the impact of bar-induced noncircular motions on the derivation of galactic rotation curves (RCs) using hydrodynamic simulations and observational data from the PHANGS-ALMA survey.

Preliminary Study of Dark-matter-dominated Systems: Further Analysis for Galactic Dark Matter Halos with Pressure

open access: yesThe Astrophysical Journal
Low-surface-brightness galaxies are excellent laboratories, where stars and baryonic matter act as tracers of the gravitational potential of the dark matter halo.
