An XMM-Newton study of the RGH 80 galaxy group
Y. -J. Xue, H. Boehringer, K. Matsushita
We present an X-ray study of the galaxy group RGH 80, observed by XMM-Newton. The X-ray emission of the gas is detected out to ~ 462h^{-1}_{50} kpc, corresponding to ~ 0.45 r_{200}…

Autocorrelation function of the soft X-ray background produced by warm-hot gas in dark halos
Xiang-Ping Wu, Yan-Jie Xue
We calculate the angular two-point autocorrelation function (ACF) of the soft X-ray background (SXRB) produced by the warm-hot intergalactic medium (WHIM) associated with dark halo…

Can radiative cooling and nongravitational heating explain simultaneously the global X-ray properties of clusters and the unresolved cosmic X-ray background ?
Yan-Jie Xue, Xiang-Ping Wu
Using a simple analytic approach we address the question of whether radiative cooling, nongravitational heating and cooling plus heating models can simultaneously explain the obser…
