ROSAT observations of the soft X-ray background and of the cluster soft excess emission in the Hercules supercluster
Max Bonamente, Richard Lieu, Jelle Kaastra
Recent observations with the XMM-Newton satellite confirmed the existence of the soft excess phenomenon in galaxy clusters, earlier discovered in several EUVE, ROSAT and BeppoSAX o…
GRB 050911: a black hole - neutron star merger or a naked GRB
K. L. Page, A. R. King, A. J. Levan +16
GRB 050911, discovered by the Swift Burst Alert Telescope, was not seen 4.6 hr later by the Swift X-ray Telescope, making it one of the very few X-ray non-detections of a Gamma-Ray…
Determination of the Cosmic Distance Scale from Sunyaev-Zel'dovich Effect and Chandra X-ray Measurements of High Redshift Galaxy Clusters
M. Bonamente, M. Joy, S. La Roque +3
We determine the distance to 38 clusters of galaxies in the redshift range 0.14 < z < 0.89 using X-ray data from Chandra and Sunyaev-Zeldovich Effect data from the Owens Valley Rad…
Cross-Correlation analysis of WMAP and EGRET in Wavelet Space
Xin Liu, Shuang Nan Zhang
We cross correlate the Wilkinson Microwave Anisotropy Probe (WMAP) first year data and the diffuse gamma-ray intensity maps from the Energetic Gamma Ray Experiment Telescope (EGRET…
Magnetic topologies and two-class coronal mass ejections: a numerical magnetohydrodynamic study
W. Liu, X. P. Zhao, S. T. Wu +1
White-light observations of the solar corona show that there are two characteristic types of Coronal Mass Ejections (CMEs) in terms of speed-height profiles: so-called fast CMEs th…
Forming supermassive black holes by accreting dark and baryon matter
Jian Hu, Yue Shen, Yu-Qing Lou +1
Given a large-scale mixture of self-interacting dark matter (SIDM) particles and baryon matter distributed in the early Universe, we advance here a two-phase accretion scenario for…
The Sunyaev-Zel'dovich effect in a sample of 31 clusters - a comparison between the X-ray predicted and WMAP observed CMB temperature decrement
Richard Lieu, Jonathan P. D. Mittaz, Shuang-Nan Zhang
The WMAP Q, V, and W band radial profiles of temperature deviation of the cosmic microwave background (CMB) were constructed for a sample of 31 randomly selected nearby clusters of…
CASTER - a concept for a Black Hole Finder Probe based on the use of new scintillator technologies
Mark L. McConnell, Peter F. Bloser, Gary Case +13
The primary scientific mission of the Black Hole Finder Probe (BHFP), part of the NASA Beyond Einstein program, is to survey the local Universe for black holes over a wide range of…
Black hole X-ray binaries LMC X-1 and X-3: observations confront spectral models
Yangsen Yao, Q. Daniel Wang, Shuang Nan Zhang
We present a comprehensive spectral analysis of black hole X-ray binaries, LMC X-1 and LMC X-3, based on BeppoSAX observations. We test both the multi-color disk plus power law (MC…
Critical Examinations of QSO Redshift Periodicities and Associations with Galaxies in Sloan Digital Sky Survey Data
Su Min Tang, Shuang Nan Zhang
We have used the publicly available data from the Sloan Digital Sky Survey and 2dF QSO Redshift Survey to test the hypothesis that QSOs are ejected from active galaxies with period…
The temperature structure in the core of Sersic 159-03
J. de Plaa, J. S. Kaastra, M. Mendez +6
We present results from a new 120 ks XMM-Newton observation of the cluster of galaxies Sersic 159-03. In this paper we focus on the high-resolution X-ray spectra obtained with the…
Thermal and non-thermal nature of the soft excess emission from Sersic 159-03 observed with XMM-Newton
M. Bonamente, R. Lieu, J. P. D. Mittaz +2
Several nearby clusters exhibit an excess of soft X-ray radiation which cannot be attributed to the hot virialized intra-cluster medium. There is no consensus to date on the origin…
Probing the Spatial Distribution of the Interstellar Dust Medium by High Angular Resolution X-ray Halos of Point Sources
Jingen Xiang, Shuang Nan Zhang, Yangsen Yao
We studied the X-ray dust scattering halos around 17 bright X-ray point sources using {\it Chandra} data. We use an iterative method to resolve the halos at small scattering angles…
Non-Gaussianity due to Possible Residual Foreground Signals in WMAP 1st-year Data Using Spherical Wavelet Approaches
Xin Liu, Shuang Nan Zhang
We perform multi-scale non-Gaussianity detection and localization to the Wilkinson Microwave Anisotropy Probe (WMAP) first-year data in both wavelet and real spaces. Such an analys…
Submillimetre photometry of X-ray absorbed QSOs: their formation and evolutionary status
J. A. Stevens, M. J. Page, R. J. Ivison +4
We present an analysis of the submillimetre/X-ray properties of 19 X-ray absorbed, Compton-thin quasi-stellar objects (QSOs) selected to have luminosities and redshifts which repre…
The transient hard X-ray tail of GX 17+2: new BeppoSAX results
R. Farinelli, F. Frontera, A. A. Zdziarski +5
We report on results of two BeppoSAX observations of the Z source GX 17+2. In both cases the source is in the horizontal branch of the colour-intensity diagram. The persistent cont…
The Cluster Soft Excess: new faces of an old enigma
Richard Lieu, Jonathan Mittaz
Until the advent of XMM-Newton, the cluster soft excess (CSE) was the subject of some controversy due to both data analysis issues and uncertainties with the soft excess emission m…
Testing the Gamma-Ray Burst Energy Relationships
David L. Band, Robert D. Preece
Building on Nakar & Piran's analysis of the Amati relation relating gamma-ray burst peak energies E_p and isotropic energies E_iso, we test the consistency of a large sample of BAT…
