The symbiotic system AG Draconis: Soft X ray bremsstrahlung from the nebulae

Cu 1.75 S identified, using X-ray diffraction analysis, products from the pretreatment of the chalcocite mineral with 30 kg/t H 2 SO 4 , 40 kg/t NaCl and 7 days of curing time at

The three Cycle 14 X-ray point source detections (HbDs1, NGC 6337, Sp 1) continue the trend, noted in Paper I, that soft (∼0.6–1.0 keV) X-ray sources likely indicate the presence

As a first step, we verify the analysis procedure using simu- lated point-like sources with the computed spectra correspond- ing to (1) the inner part of the lunar disk (the total

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

In addition to two learning modes that are articulated in the literature (learning through incident handling practices, and post-incident reflection), the chapter

• 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)

To do that, we have introduced, for both the case of trivial and non-trivial ’t Hooft non-abelian flux, the back- ground symmetric gauge: the gauge in which the stable SU (N )

These data collectively show PN spectra with thermal dust continua, nebular emission lines, and a variety of dust signatures, with characteristics of carbon-rich and
