Maryland Shared Open Access Repository

MD-SOAR is a shared digital repository platform for eleven colleges and universities in Maryland. It is currently funded by the University System of Maryland and Affiliated Institutions (USMAI) Library Consortium (usmai.org) and other participating partner institutions. MD-SOAR is jointly governed by all participating libraries, who have agreed to share policies and practices that are necessary and appropriate for the shared platform. Within this broad framework, each library provides customized repository services and collections that meet local institutional needs. Please follow the links below to learn more about each library's repository services and collections.

  • Reconstruction of Electron and Ion Distribution Functions in a Magnetotail Reconnection Diffusion Region 

    Ng, Jonathan; Chen, Li-Jen; Hakim, Ammar; Bhattacharjee, Amitava (American Geophysical Union, 2020-05-23)
    In the diffusion region of magnetotail reconnection, particle distributions are highly structured, exhibiting triangular shapes and multiple striations that deviate dramatically from the Maxwellian distribution. Fully ...

  • On the rate of energy deposition by an ion ring velocity beam 

    Omelchenko, Yuri A.; Rudakov, Leonid; Ng, Jonathan; Crabtree, Chris; Ganguli, Gurudas (AIP Publishing, 2021-05-03)
    Using a novel three-dimensional electromagnetic hybrid code, XHYPERS, we simulate the generation of lower hybrid oscillations in a magnetized plasma by a heavy ion beam with a ring-shaped velocity distribution over much ...

  • Magnetopause Reconnection and Indents Induced by Foreshock Turbulence 

    Chen, Li-Jen; Ng, Jonathan; Omelchenko, Yuri; Wang, Shan (American Geophysical Union, 2021-05-31)
    Abstract Based on global hybrid simulation results, we predict that foreshock turbulence can reach the magnetopause and lead to reconnection as well as Earth-sized indents. Both the interplanetary magnetic field (IMF) and ...

  • A Case Study of Nonresonant Mode 3-s ULF Waves Observed by MMS 

    Wang, Shan; Chen, Li-Jen; Ng, Jonathan; Bessho, Naoki; Le, Guan; Fung, Shing F.; Gershman, Daniel J.; Giles, Barbara L. (American Geophysical Union, 2020-11-16)
    The nature of the 3-s ultralow frequency (ULF) wave in the Earth's foreshock region and the associated wave-particle interaction are not yet well understood. We investigate the 3-s ULF waves using Magnetospheric Multiscale ...

  • Lower-Hybrid-Drift Vortices in the Electron-Scale Magnetic Reconnection Layer 

    Ng, Jonathan; Chen, L.-J.; Le, A.; Stanier, A.; Wang, S.; Bessho, N. (American Geophysical Union, 2020-11-10)
    Abstract Lower-hybrid-drift waves driving vortical flows have recently been discovered in the electron current layer during magnetic reconnection in the terrestrial magnetotail. Yet, spacecraft measurements cannot address ...
