Variability, flaring and coherence -- the complementarity of the maser and superradiance regimes
Martin Houde, Fereshteh Rajabi, Gordon C. MacLeod +5
We discuss the role that coherence phenomena can have on the intensity variability of spectral lines associated with maser radiation. We do so by introducing the fundamental cooper…
A Keplerian disk with a four-arm spiral birthing an episodically accreting high-mass protostar
R. A. Burns, Y. Uno, N. Sakai +34
High-mass protostars (M 8 M) are thought to gain the majority of their mass via short, intense bursts of growth. This episodic accretion is thought to be faci…
A heat-wave of accretion energy traced by masers in the G358-MM1 high-mass protostar
R. A. Burns, K. Sugiyama, T. Hirota +20
High-mass stars are thought to accumulate much of their mass via short, infrequent bursts of disk-aided accretion. Such accretion events are rare and difficult to observe directly…
Ammonia masers toward G358.931-0.030
T. P. McCarthy, S. L. Breen, J. F. Kaczmarek +9
We report the detection of ammonia masers in the non-metastable (6, 3), (7, 5) and (6, 5) transitions, the latter is the first unambiguous maser detection of that transition ever m…
Modelling of the multi-transition periodic flaring in G9.62+0.20E
F. Rajabi, M. Houde, G. C. MacLeod +5
We present detailed modeling of periodic flaring events in the 6.7 GHz and 12.2 GHz methanol lines as well as the OH 1665 MHz and 1667 MHz transitions observed in the G9.62+0.20E s…
Multi-frequency VLBI observations of maser lines during the 6.7~GHz maser flare in the high-mass young stellar object G24.330.14}
A. Kobak, A. Bartkiewicz, M. Szymczak +13
Recent studies have shown that 6.7 GHz methanol maser flares can be a powerful tool for verifying the mechanisms of maser production and even the specific signatures of accretion r…
The evolution of the H2O maser emission in the accretion burst source G358.93-0.03
O. S. Bayandina, C. L. Brogan, R. A. Burns +10
The massive young stellar object (MYSO) G358.93-0.03-MM1 showed an extraordinary near-infrared- to (sub-)millimetre-dark and far-infrared-loud accretion burst, which is closely ass…
A note on the periodic methanol masers in G9.62+0.20E
DJ van der Walt, JM Maswanganye, S Etoka +2
A number of mechanisms to understand the periodic class II methanol masers associated with some high-mass star forming regions have been proposed in the past. Two recent proposals,…
