Wright, Darren M., Watt, Clare E. J., Rae, I. Johnathan, Rankin, Robert
We present results from self-consistent simulations of the electron response to shear Alfvén pulses in the presence of non-uniform magnetic fields and the associated mirror force. We discuss how energies of resonantly accelerated beam particles are affected by the local phase velocity of the...

Interaction of ULF waves with different ion species: Pitch angle and phase space density implications
Download2016
Ren, Jie, Zong, Qui-Gang, Rankin, Robert, Zhou, Xuzhi, Wang, Y. F.
ULF waves can accelerate/decelerate the charged particles including the ring current ions via drift-bounce resonance, which play an important role in the dynamics of ring current during storm times. This study compares the different behaviors of oxygen ions (10.5–35.1 keV) and protons (0.3–12.3...

Rankin, Robert, Ridley, Aaron J., Gombosi, Tamas I., Clauer, C. Robert, Watanabe, Masakazu, Kabin, Konstantin, Sofko, George J.
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field ( IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated...

International Collaboration Within the United Nations Committee on the Peaceful Uses of Outer Space: Framework for International Space Weather Services (2018–2030)
Download2018-05-06
Mann, I. R., Di Pippo, S., Opgenoorth, H. J., Kuznetsova, M., Kendall, D. J.
Severe space weather is a global threat that requires a coordinated global response. In this Commentary, we review some previous successful actions supporting international coordination between member states in the United Nations (UN) context and make recommendations for a future approach. Member...

Inverse resonance absorption in an inhomogeneous magnetized plasma
1985
Barr, H. C., Rankin, Robert. , Boyd, T. J. M., Gardner, G. A.
The linear mode conversion of a plasma wave to a light wave in a magnetized plasma has been examined theoretically and by computer simulation. This conversion is the inverse of resonance absorption exhibiting an identical dependence on magnetic field and density scale length with an optimum...

Kelvin‐Helmholtz unstable magnetotail flow channels: Deceleration and radiation of MHD waves
Download2014
Turkakin, Hava, Rankin, Robert, Mann, Ian R.
The Kelvin-Helmholtz instability (KHI) of magnetotail flow channels associated with bursty bulk flows (BBFs) is investigated. MHD oscillations of the channel in both kink and sausage modes are investigated for KHI, and both the primary and secondary KHIs are found that drive MHD waves. These...

Kinetic theory of stimulated Raman sidescattering from magnetized plasmas
1985
Boyd, T. J. M., Rankin, Robert
A theory of stimulated Raman sidescattering in magnetized plasmas is presented based on a solution of the Vlasov–Maxwell equations. The incident laser light, in the form of extraordinary mode radiation, decays into light waves which propagate along the uniform magnetic field as right or left...

Helen Yam, Douglas R Schmitt, Gautier Njiekak,, Gabriela Davila
These sample characterization and ultrasonic laboratory measurements were collected as part of the M.Sc. thesis of Helen Yam (Yam, H., CO2 Rock Physics: A Laboratory Study, M.Sc. Thesis, University of Alberta, https://doi.org/10.7939/R36704, 2011). Some of these data are presented and analyzed...

Lord of the Rings - Return of the King: Swift-XRT observations of dust scattering rings around V404 Cygni

Beardmore, A. P., Willingale, R., Kuulkers, E., Altamirano, Diego, Motta, S. E., Osborne, J. P., Page, Kim L., Sivakoff, Gregory Robert
On 2015 June 15, the black hole X-ray binary V404 Cygni went into outburst, exhibiting extreme X-ray variability which culminated in a final flare on June 26. Over the following days, the Swift-X-ray Telescope detected a series of bright rings, comprising five main components that expanded and...

Zhang, Zhongli, Gilfanov, Marat, Voss, Rasmus, Sivakoff, Gregory Robert, Kraft, Ralph P., Brassington, Nicola J., Kundu, Arunav, Jordán, Andrés Jordán, Sarazin, Craig, L.
Aims. Based on the archival data from the Chandra observations of nearby galaxies, we study different sub populations of low-mass X-ray binaries (LMXBs) – dynamically formed systems in globular clusters (GCs) and in the nucleus of M 31 and (presumably primordial) X-ray binaries in the fields of...
