Cold HI ejected into the Magellanic Stream

J. Dempsey, N. M. McClure-Griffiths, K. Jameson +1

We report the direct detection of cold HI gas in a cloud ejected from the Small Magellanic Cloud (SMC) towards the Magellanic Stream. The cloud is part of a fragmented shell of HI…

Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays

D. R. Madison, X. -J. Zhu, G. Hobbs +23

By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…

The disturbance of a millisecond pulsar magnetosphere

R. M. Shannon, L. T. Lentati, M. Kerr +21

Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately me…
