Frycz, P., Samson, J. C., Rankin, Robert

Using a compressible, three-dimensional resistive monohydrodynamic (MHD) computer simulation code, we examine the evolution of standing wave field line resonances (FLRs) in the nightside of the Earth's magnetosphere. The MHD code that is used allows for a full nonlinear description and enables us...

Petrosyan, Rafayel, Narayan, Abhishek, Woodside, Michael T

The use of force probes to induce unfolding and refolding of single molecules through the application of mechanical tension, known as single-molecule force spectroscopy (SMFS), has proven to be a powerful tool for studying the dynamics of protein folding. Here we provide an overview of what has...

Schriver, David, Trávníček, Pavel M., Rankin, Robert, Paral, Jan

Two flybys of Mercury by the NASA MESSENGER spacecraft on January 14 and October 6, 2008 provide insight into the spatial distribution of the heavy ion exosphere around the planet. The relatively quiet solar wind conditions and interplanetary magnetic field (IMF) orientation allow us to compare...

Software developed to calculate the stress concentrations in the vicinity of a borehole drilled at an arbitrary direction through an elastically anisotropic rock formation. The code developed is based on the Lekhnitskij-Amadei solution. This code is associated with Li, W., D.R. Schmitt, M....

Liu, Y., Zong, Qui-Gang, Rankin, Robert, Zhou, Xuzhi, Foster, John C.

“Zebra stripes” are newly found energetic electron energy-spatial (L shell) distributed structure with an energy between tens to a few hundreds keV in the inner radiation belt. Using high-quality measurements of electron fluxes from Radiation Belt Storm Probes Ion Composition Experiment (RBSPICE)...

Fenrich, Frances R., Nedie, Abiyu Z., Rankin, Robert

Ultra-low frequency (ULF) field line resonances (FLRs) cause oscillations in F-region plasma flows and can be detected in SuperDARN measured line-of-sight (l-o-s) velocities. In this paper, we characterize a ULF wave event with coordinated use of SuperDARN HF radars, optical instrumentation,...

Russell, Thomas D., Soria, Roberto, Miller-Jones, James C. A., Curran, P. A., Markoff, Sera, Russell, D. M., Sivakoff, Gregory Robert

We present the results of our quasi-simultaneous radio, submm, infrared, optical and X-ray study of the Galactic black hole candidate X-ray binary MAXI J1836−194 during its 2011 outburst. We consider the full multiwavelength spectral evolution of the outburst, investigating whether the evolution...

Curran, P. A., Coriat, Mickael, Miller-Jones, James C. A., Armstrong, R. P., Edwards, P. G., Sivakoff, Gregory Robert, Woudt, Patrick Alan, Altamirano, Diego, Belloni, Thomaso. M., Corbel, Stephane, Fender, Rob P., Körding, Elmar. G., Krimm, H. A., Markoff, Sera, Migliari, Simone, Russell, D. M., Stevens, J., Tzioumis, T.

Swift J1745−26 is an X-ray binary towards the Galactic Centre that was detected when it went into outburst in 2012 September. This source is thought to be one of a growing number of sources that display ‘failed outbursts’, in which the self-absorbed radio jets of the transient source are never...

Frycz, P., Samson, J. C., Rankin, Robert, Harrold, B. G.

Magnetohydrodynamic, field line resonances in the Earth's magnetosphere can have very large velocity shears and field-aligned currents. Auroral radar measurements of high-latitude resonances indicate that the velocities associated with the resonances in the E and F regions am often substantially...

Shankar, Francesco, Sivakoff, Gregory Robert, Vestergaard, Marianne, Dai, Xinyu

We cross-correlate the Sloan Digital Sky Survey Data Release 3 quasar sample with Faint Images of the Radio Sky at Twenty centimetres (FIRST) and the Vestergaard et al. black hole (BH) mass sample to compare the mean accretion histories of optical and radio quasars. We find significant...
