DSpace/Manakin Repository

BEARdocs is currently undergoing a scheduled upgrade. We expect the upgrade to be completed no later than Monday, March 2nd, 2015. During this time you will be able to access existing documents, but will not be able to log in or submit new documents.



CASPER conducts fundamental research in astrophysics, early universe cosmology, space physics, superstring / M theory, complex (dusty) plasma physics, hypervelocity impact (shock) physics and laser hypervelocity impact simulation physics.

  • Yousefi, Raziyeh; Davis, Allen; Carmona-Reyes, Jorge; Matthews, Lorin; Hyde, Truell (Physical Review E, )
    Understanding the agglomeration of dust particles in complex plasmas requires knowledge of basic properties such as the net electrostatic charge and dipole moment of the dust. In this study, dust aggregates are formed from ...
  • Matthews, L.S.; Shotorban, B.; Hyde, T.W. (Astrophysical Journal, )
    The coagulation of cosmic dust grains is a fundamental process which takes place in astrophysical environments, such as presolar nebulae and circumstellar and protoplanetary disks. Cosmic dust grains can become charged ...
  • Kupper, M.; de Beule, C.; Wurm, G.; Matthews, L.; Kimery, J.; Hyde, T.W. (Journal of Aerosol Science, )
    Photophoresis is a force which can dominate the motion of illuminated aerosols in low pressure environments of laboratory experiments, planetary atmospheres or protoplanetary disks. In drop tower experiments we quantified ...
  • Kong, J.; Qiao, K.; Matthews, L.S.; Hyde, T.W. (Physical Review E, )
    Small number dust particle clusters can be used as probes for plasma diagnostics. The number of dust particles as well as cluster size and shape can be easily controlled employing a glass box placed within a Gaseous ...
  • Hartmann, P.; Kovacs, A. Z.; Carmona-Reyes, J.; Matthews, L.S.; Hyde, T.W. (Plasma Sources Science and Technology, )
    Using dust grains as probes in gas discharge plasma is a very promising, but at the same time very challenging method, as the individual external control of dust grains has to be solved. We propose and demonstrate the ...
