Millimetre Observations of Maser-Emitting Planetary Nebulae

Galaxies, 2022
Observations in the millimetre bands of maser-emitting planetary nebulae (PNe) are crucial to study their circumstellar molecular gas at the beginning of the PN phase.

High-sensitivity Observations of the H2O Megamasers of NGC 1068: Precise Astrometry and Detailed Kinematics

The Astrophysical Journal, 2023
We present High Sensitivity Array observations of the H _2 O megamasers of NGC 1068. We obtain absolute astrometry with 0.3 mas precision that confirms the association of the disk masers with the nuclear radio continuum source S1.

MASERS AS TRACERS OF ANGULAR MOMENTUM IN MOLECULAR OUTFLOWS

Tecnociencia, 2023
The dissipation of angular momentum of collapsing molecular cores is a key component in the formation of stars. Previous observations have reported that highly collimated protostellar jets can remove angular momentum from low-mass protostars.
