H₂O MegaMaser emission in NGC 4258 indicative of a periodic disc instability

Harnessing the resolving power of space very long baseline interferometry results in a link between 22 GHz H₂O MegaMaser emission and accretion activity in the thin disc around the nucleus of galaxy NGC 4258. The emission regions appear consistent with a periodic magneto-rotational instability in the disc.

New maser species tracing spiral-arm accretion flows in a high-mass young stellar object

Conditions in an accretion burst around a high-mass young stellar object (HMYSO) were sufficient to pump two species previously not known to maser. HDO and HNCO were found to trace spiral-arm features in the accretion flow onto the HMYSO.
