Machine-learning approaches to dispersion measure estimation for fast radio bursts
Hosein Rajabi, Zhejian Liu, Fereshteh Rajabi +1
Fast radio bursts (FRBs) are bright, mostly millisecond-duration transients of extragalactic origin whose emission mechanisms remain unknown. As FRB signals propagate through ioniz…
Quantum coherence and the invisible Universe: Subradiance as a dark matter mechanism
Martin Houde, Fereshteh Rajabi, Lamies Sati +1
The origin of dark matter in galactic halos, one of the deepest unsolved problems in astrophysics, may find an unexpected contribution from the quantum mechanics of ordinary atomic…
Relativistic Maxwell-Bloch Equations with Applications to Astrophysics
Ningyan Fang, Victor Botez, Fereshteh Rajabi +1
We derive relativistic Maxwell-Bloch equations for potential applications in astronomical environments, where various radiative processes are known to occur, including the maser ac…
Impact of propagation effects on the spectro-temporal properties of Fast Radio Bursts
Aishwarya Kumar, Fereshteh Rajabi, Martin Houde
We present a mathematical analysis of propagation-induced distortions in the spectro-temporal properties of Fast Radio Bursts (FRBs). Within the Triggered Relativistic Dynamical Mo…
