Synchronized dynamics of cortical neurons with time-delay feedback
Alexandra S. Landsman, Ira B. Schwartz
The dynamics of three mutually coupled cortical neurons with time delays in the coupling are explored numerically and analytically. The neurons are coupled in a line, with the midd…
Power spectra of black holes and neutron stars as a probe of hydrodynamical structure of the source. Diffusion theory and its application to Cyg X-1 and Cyg X-2 X-ray observations
Lev Titarchuk, Nikolai Shaposhnikov, Vadim Arefiev
We present a model of Fourier Power Density Spectrum (PDS) formation in accretion powered X-ray binary systems derived from the first principles of the diffusion theory. Timing pro…
Tracing Ghost Cavities with Low Frequency Radio Observations
Tracy Clarke, Elizabeth Blanton, Craig Sarazin +5
We present X-ray and multi-frequency radio observations of the central radio sources in several X-ray cavity systems. We show that targeted radio observations are key to determinin…
Dipole moments from atomic-number-dependent potentials in analytic density-functional theory
Brett I. Dunlap, Shashi P. Karna, Rajendra R. Zope +1
Molecular dipole moments of analytic density-functional theory are investigated. The effect of element-dependent exchange potentials on these moments are examined by comparison wit…
Monitoring the Bi-Directional Relativistic Jets of the Radio Galaxy 3C 338
G. Gentile, C. Rodriguez, G. B. Taylor +4
We present the analysis of VLA and VLBA observations of the radio source 3C 338, associated with the cD galaxy NGC 6166, the central dominant galaxy of the cluster Abell 2199. The…
GLAST Large Area Telescope Multiwavelength Planning
O. Reimer, P. F. Michelson, R. A. Cameron +3
Gamma-ray astrophysics depends in many ways on multiwavelength studies. The Gamma-ray Large Area Space Telescope (GLAST) Large Area Telescope (LAT) Collaboration has started multiw…
