TL;DR: In this paper, the contribution of normal and starburst galaxies to the populations which make up the X-ray background and present their directly measured Xray number counts is described. And the authors look to the future, suggesting that it is important that the populatio n of X -ray faint normal and Starburst galaxies be well constrained in order to design the next generation of Xray observatories, which will outnumber the "mighty" AGN.

TL;DR: In this article, the authors show that the absorbers are more complicated than previous simple models assumed; current absorber models need to be extended to the high-luminosity, high-velocity, and high-ionization regime appropriate for BAL QSOs.

TL;DR: In this paper, the authors present imaging and spectral analyses of Sgr A East from deep Chandra observations, and propose that the cannonball is a candidate neutron star created by the supernova that also produced the remnant SgrA East.

TL;DR: In this article, Chandra X-ray observations of the Galactic center with the ACIS instrument on the Chandra Xray Observatory reveal a wealth of detail in the spatial distribution and the spectrum of the hot interstellar gas.

TL;DR: In this article, the authors report on the results of their monitoring program of SNR 1987A with the Chandra X-Ray Observatory, showing that the blast wave has reached the dense inner ring on the western side of the SNR, as well as in the east.
