... Pulsars offer a variety of observables for study of interstellar scattering. Observations of scattering of nearby pulsars and intra-day variable quasars point to the existence of a component of the interstellar medium (ISM) which has properties quite different from the more distant, diffuse ISM. ... The time series of electric field emitted by the pulsar is convolved with an impulse-response function due to scattering, when sampled at the observer plane [1]. ... Nearby interstellar scattering. ...

... Almost all DSOs require a telescope to see in any detail at all, though some can be detected with just binoculars, and a few can be barely seen with the unaided eye. ... DEGREE: Distances on the sky (sometimes called the celestial sphere) are measured in angular degrees rather than inches or feet. ... The magnification is the focal length of the telescope divided by the focal length of the eyepiece. ... Short focal length eyepieces are also termed high power, long focal length are low power. ...

... X-ray data of GX 3+1 (4U 1744-26) obtained in broad energy ranges using BeppoSAX (0.1­200 keV) and Rossi X-Ray Timing Explorer (RXTE) (3­200 keV) offer a unique The Astrophysical Journal, 747:99 (15pp), 2012 March 10 Seifina & Titarchuk possibility to further investigate, in detail, the evolution of X-ray spectral properties during transition events. ... In Figure 2, we illustrate our spectral model as a basic model for fitting the BeppoSAX and RXTE spectral data for GX 3+1. ... Figure 4. ...
