PublicationThe Kinematics of the HH 399 Jet in the Trifid Nebula
We have studied the kinematics of the HH 399 jet, which was recently discovered in the Trifid Nebula. The data were obtained in the [N II] 6583 Å line with a...

PublicationThe Kinematics of the Ionized and Molecular Hydrogen in the Starburst Galaxy NGC 253
Near-infrared H2 1-0 5(1) and Brγ velocity curves along the major axis of NGC 253 have revealed a central velocity gradient that is 7 times steeper than that...

PublicationThe kinematics of the quadrupolar nebula M 1-75 and the identification of its central star
Context. The link between how bipolar planetary nebulae are shaped and their central stars is still poorly understood. Aims: This paper investigates the...

PublicationThe kinematics of water masers in the stellar molecular outflow source, IRAS 19134+2131
Using the Very Large Array (VLA) and the Very Long Baseline Array (VLBA), we have observed water maser emission in the proto-planetary nebula candidate IRAS...
