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…
