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…
Dwarf galaxies in non-local gravity
Ivan De Martino, Riccardo Della Monica, Mahmood Roshan
The nature of dark matter remains one of the most pressing open questions in modern cosmology. Despite extensive experimental efforts, no direct or indirect detection of dark matte…
Dynamical friction by coupled dark energy
Nasrin Nari, Mahmood Roshan
In this paper, we examine dynamical friction at galactic scales within the framework of coupled dark energy. This model posits dark energy as coupled quintessence, which maintains…
