After 3 h of persistent emission, the persistent luminescence intensity was still kept (Fig. 4b).
Soft gamma repeaters (SGRs) undergo changes in their pulse properties and persistent emission during episodes of intense burst activity.
In this paper, we discuss our first attempts to model the broadband persistent emission of magnetars within a self-consistent, physical scenario.
We report the XMM-Newton detection of narrow Fe xxv and Fe xxvi X-ray absorption lines at 7 keV in the persistent emission of the dipping low-mass X-ray binary (LMXB) 4U 1323−62.
Here, we review the global properties of SGRs as well as the observed dynamics of the pulsed and persistent emission properties of SGR 1900+14, SGR 1806-20 and SGR 1627-41 during and following burst active episodes and discuss what implications these results have for the burst emission mechanism, the magnetic field dynamics of magnetars, the nature of the torque variability, and SGRs in general.
The kinetic parameters, determined from thermoluminescent glow curves, provide evidence about a possible persistent luminescence emission from the (Ba0.97Tm0.03 MoO4 sample.
We find that oxygen vacancies occur in a high concentration and introduce a dispersive empty defect band, which is distributed over a wide energy range and located from shallow to deep depth, explaining well the persistent luminescence emission with an intense intensity and a long-lasting duration.
The result, he said, is that the faint persistent plume of emissions from the attack site "is sort of prowling the city overnight, meandering.
"Many saw the [global financial crisis] as an opportunity to move the global economy away from persistent and high emissions growth," Glen Peters, a researcher at the Center for International Climate and Environmental Research in Oslo and one of the leaders of the project, said.
The study, published as a paper in the peer-review journal Nature Geoscience, called "Persistent growth of CO2 emissions and implications for reaching climate targets", is a collaboration of research groups around the world.
