The onset of stellar bars at Cosmic Noon. Bar-driven quenching and AGN co-evolution in a mature disc galaxy
Luca Costantin, Lorenzo Morelli, Cristina Cabello +15
Observations with the JWST revealed an unexpected abundance of barred galaxies at Cosmic Noon. However, the physical properties of these early bars are almost unconstrained, as it…
Jeans criterion in hydrostatic stratified media
Mahmood Roshan, Asiyeh Habibi
The classical Jeans stability criterion neglects spatial gradients in background physical quantities such as density and pressure. Here, we revisit the Jeans analysis for a non-rot…
A bar stability criterion distinguishing between modified gravity and dark matter in galaxies
Tahere Kashfi, Mahmood Roshan, Virginia Cuomo +3
This paper presents a study on the distinguishability of dark matter and Modified Newtonian Dynamics (MOND) at galactic scales based on the stability criterion proposed by Efstathi…
The Tremaine-Weinberg method at high redshifts
Mahmood Roshan, Asiyeh Habibi, J. Alfonso L. Aguerri +11
This paper examines the reliability of the Tremaine-Weinberg (TW) method in measuring the pattern speed of barred galaxies at high redshifts. Measuring pattern speeds at high redsh…
The redshift evolution of galactic bar pattern speed in TNG50
Asiyeh Habibi, Mahmood Roshan, Mohammad Hosseinirad +4
In this paper, the redshift evolution of the galactic bar properties, like the bar length, pattern speed, and bar fraction, has been investigated for simulated galaxies at stellar…
Thermal instability of thin accretion disks in the presence of wind and toroidal magnetic field
Asiyeh Habibi, Shahram Abbassi
We study the local thermal stability of thin accretion disks. We present a full stability analysis in the presence of a magnetic field and more importantly wind. For wind, we use a…
Fourier analysis of advection-dominated accretion flows
Asiyeh Habibi, Shahram Abbassi, Mohsen Shadmehri
We implement a new semi-analytical approach to investigate radially self-similar solutions for the steady-state advection-dominated accretion flows (ADAFs). We employ the usual …
Exact analytical solutions for ADAFs
Asiyeh Habibi, Shahram Abbassi, Mohsen Shadmehri
We obtain two-dimensional exact analytic solutions for the structure of the hot accretion flows without wind. We assume that the only non-zero component of the stress tensor is $T_…
Local stability criterion for self-gravitating disks in modified gravity
Asiyeh Habibi, Mohammad Taghi Mirtorabi, Mahmood Roshan
We study local stability of self-gravitating fluid and stellar disk in the context of modified gravity theories which predict a Yukawa-like term in the gravitational potential of a…
