Fast Population Leakage in Astronomical Masers: Maser Amplification and Transient Superradiance
Vahid Anari, Toktam Rashidi, Fereshteh Rajabi
We use a -type three-level Maxwell--Bloch model to test whether an inverted molecular transition in an astronomical maser source can produce maser amplification or superradianc…

A Unified Maxwell-Bloch Framework for Multi-periodic 6.7 GHz Methanol Flaring in G9.62+0.20E
T. Rashidi, V. Anari, O. Powles +4
We analyze a decade of 6.7 GHz methanol monitoring data in G9.62+0.20E, confirming the known periodicities of p1 = 241.3 +/- 2.3 d and p2 = 52.5 +/- 0.3 d, and identifying three ne…

Superradiance and Periodic 6.7 GHz Methanol Flaring in G22.356+0.066
T. Rashidi, V. Anari, A. Bartkiewicz +3
We present a comprehensive analysis of the periodic flares observed in the 6.7 GHz methanol transition in G22.356+0.066, utilizing the Maxwell-Bloch equations (MBEs) as a framework…
