Reheating and relic gravitational waves as remedies for degeneracies of non-canonical natural inflation
Karam Bahari, Soma Heydari, Kayoomars Karami
Here, a natural non-canonical inflationary model based on a power-law Lagrangian is investigated. We analyze the scalar spectral index and the tensor-to-scalar ratio $r…
The Effect of Flow and Magnetic Twist on Resonant Absorption of Slow MHD Waves in Magnetic Flux Tubes
Mohammad Sadeghi, Karam Bahari, Kayoomars Karami
Observations show that there are twisted magnetic flux tubes and plasma flow throughout the solar atmosphere. The main purpose of this work is to obtain the damping rate of sausage…
Warm constant-roll inflation in brane-world cosmology
Mohammad Reza Setare, Arvin Ravanpak, Karam Bahari +1
In this article we study a constant-roll inflationary model in the context of brane-world cosmology caused by a quintessence scalar field for warm inflation with a constant dissipa…
The effect of flow on resonant absorption of slow MHD waves in magnetic flux tubes
Mohammad Sadeghi, Karam Bahari, Kayoomars Karami
In this paper, we study kink and sausage oscillations in the presence of longitudinal background flow. We study resonant absorption of the kink and sausage modes in the slow contin…
Resonant absorption of kink oscillations in coronal flux tubes with continuous magnetic twist
Zanyar Ebrahimi, Karam Bahari
There are observational evidences for the existence of twisted magnetic field in the solar corona. Here, we have investigated resonant damping of the magnetohydrodynamic (MHD) kink…
