The nature of 50 Palermo Swift BAT hard X ray objects through optical spectroscopy

Roughly 50% of the PNe observed by Chandra harbor X-ray-luminous CSPNe, while soft, diffuse X-ray emission tracing shocks—in most cases, “hot bubbles”—formed by energetic

Barcel´ o’s work [2] and the Bessel functions estimates (2.0.3), these operators will be shown to be uniformly bounded in the same range of polar mixed norm spaces..

Some of these techniques, such as X-ray diffraction, X-ray photoelectron spectroscopy, Transmission electron microscopy or Raman spectroscopy, have been used rather as

• Analysis of long-term variability of high-energy sources in the optical and X-ray bands, using INTEGRAL observations from IBIS (the gamma-ray imager), JEM-X (the X-ray monitor)

We study the dark nature of GRB 130528A through multi-wavelength observations and conclude that the main reason for the optical darkness is local extinction inside of the host

We have characterized the structural and magnetic properties of these platelets by Mössbauer spectroscopy, x-ray transmission microscopy (TXM), transmission electron microscopy

To date, the most used and reliable experimental approaches for structural determination of macromolecules are X-ray crystallography, nuclear magnetic resonance (NMR) spectroscopy,

As we have seen, even though the addition of a cosmological constant to Einstein’s eld equations may be the simplest way to obtain acceleration, it has its caveats. For this rea-
