The contribution of Galactic TeV pulsar wind nebulae to Fermi large area telescope diffuse emission

25 junio in Artículos por Website

Pulsar wind nebulae are expected to contribute to γ observations both in the GeV and TeV energy domains. We indicate with ΦGeV (ΦTeV) the integrated source flux in the energy range 1–100 GeV (1–100 TeV) probed by Fermi-LAT (H.E.S.S.). We assume that all the sources in...

Sample detailsFor this study, magnetic bilayers of Au1−xPtx 4 nm/Co 2–7 nm (x = 0, 0.25. 0.5, 0.65, 0.75, 0.85, and 1) were sputter-deposited onto oxidized Si substrates and capped with MgO 2 nm/Ta 1.5 nm protective layers (see more details in the “Method” Section). The layer thicknesses are estimated...

Order to disorder in quasiperiodic composites

15 junio in Artículos por Website

The Moiré system introduced above is parameterized by r > 0 and 0 ≤ θ < 2π, which generates a diverse assortment of periodic (“finite period”) and quasiperiodic (“infinte period”) microgeometries. To numerically calculate mathematical and physical quantities, we consider finite subsets of these systems as RLC impedance networks. Different...

Extending the time of coherent optical response in ensemble of singly-charged InGaAs quantum dots

10 junio in Artículos por Website

Coherent optical response in (In,Ga)As QDsWe study n-doped (In,Ga)As quantum dots structures embedded into the microcavity with GaAs/AlAs distributed Bragg reflectors (for details see the “Methods” section). The QD emission is represented by the photoluminescence (PL) spectrum in Fig. 1a which was measured from the...
