Probing the Nature of the Vela X Cocoon
Stephanie M. LaMassa, Patrick O. Slane, Okkie C. de Jager
Vela X is a pulsar wind nebula (PWN) associated with the active pulsar B0833-45 and contained within the Vela supernova remnant (SNR). A collimated X-ray filament ("cocoon") extend…
Probing the radio to X-ray connection of the Vela X PWN with Fermi LAT and H.E.S.S
O. C. de Jager, P. O. Slane, S. LaMassa
Morphologically it appears as if the Vela X PWN consists of two emission regions: whereas X-ray (1 keV) and very high energy (VHE) H.E.S.S. gamma-ray observations appear to define…
Echo Spectroscopy of Atomic Dynamics in a Gaussian Trap via Phase Imprints
Daniel Oblak, Juergen Appel, Patrick Windpassinger +3
We report on the collapse and revival of Ramsey fringe visibility when a spatially dependent phase is imprinted in the coherences of a trapped ensemble of two-level atoms. The phas…
Estimating the birth period of pulsars through GLAST/LAT observations of their wind nebulae
O. C. de Jager
In this paper we show that the high energy -ray flux in the GeV domain from mature pulsar wind nebulae (PWN) scales as the change in rotational kinetic energy s…
High purity bright single photon source
J. S. Neergaard-Nielsen, B. Melholt Nielsen, H. Takahashi +2
Using cavity-enhanced non-degenerate parametric downconversion, we have built a frequency tunable source of heralded single photons with a narrow bandwidth of 8 MHz, making it comp…
