Sgr a East and Its Surroundings Observed in X-rays
We report the results of an XMM-Newton observation of Sgr A East and its surroundings. The X-ray spectrum of Sgr A East is well represented with a two-temperature plasma model with temperatures of ∼1 and ∼4 keV. Only the iron abundance shows clear spatial variation; it concentrates in the core of Sgr A East. The derived plasma parameters suggest that Sgr A East originated in a single supernova....
متن کاملDetailed analysis of observed antiprotons in cosmic rays
In the present work, the origin of antiprotons observed in cosmic rays (above the atmosphere) is analyzed in details. We have considered the origin of the primaries, (which their interactions with the interstellar medium is one of the most important sources of antiprotons) is a supernova type II then used a diffusion model for their propagation. We have used the latest parameterization for anti...
متن کاملHigh-energy X-rays from J174545.5-285829, the Cannonball: a Candidate Pulsar Wind Nebula Associated with Sgr a East
We report the unambiguous detection of non-thermal X-ray emission up to 30 keV from the Cannonball, a few-arcsecond long diffuse X-ray feature near the Galactic Center, using the NuSTAR X-ray observatory. The Cannonball is a high-velocity (vproj ∼ 500 km s ) pulsar candidate with a cometary pulsar wind nebula (PWN) located ∼ 2 north-east from Sgr A*, just outside the radio shell of the supernov...
متن کاملX-rays from Cepheus A East and West
We report the discovery of X-rays from both components of Cepheus A, East and West, with the XMM-Newton Observatory. HH 168 joins the ranks of other energetic Herbig Haro objects that are sources of T$10 6 K X-ray emission. The HH 168 effective temperature is T = 5.8 (+3.5,-2.3) x 10 6 K and its unabsorbed luminosity is 1.1 x 10 29 erg s -1 , making it hotter and less luminous than other repres...
متن کاملPreflare Nonthermal Emission Observed in Microwaves and Hard X-Rays
We present a detailed examination on nonthermal emissions during the preflare phase of the X4.8 flare that occurred on 2002 July 23. The microwave (17GHz and 34GHz) data obtained with the Nobeyama Radioheliograph at Nobeyama Solar Radio Observatory and the hard X-ray data taken with the Reuven Ramaty High Energy Solar Spectroscopic Imager obviously showed nonthermal features in the preflare pha...
