Effects of Galaxy Formation on Thermodynamics of the Intracluster Medium
We present detailed comparisons of the intracluster medium (ICM) in cosmological Eulerian cluster simulations with deep Chandra observations of nearby relaxed clusters. To assess the impact of galaxyExpand
Testing X-ray Measurements of Galaxy Clusters with Cosmological Simulations
X-ray observations of galaxy clusters potentially provide powerful cosmological probes if systematics due to our incomplete knowledge of the ICM physics is understood and controlled. In this paper weExpand
A new robust low-scatter X-ray mass indicator for clusters of galaxies
We present a comparison of X-ray proxies for the total cluster mass, M_(500), including the spectral temperature (T_X), gas mass measured within r_(500) (M_(g,500)), and the new proxy, Y_X, which isExpand
D-branes and spinning black holes
Abstract We obtain a new class of spinning charged extremal black holes in five dimensions, considered both as classical configurations and in the Dirichlet (D)-brane representation. The degeneracyExpand
Efficient Generation of Jets from Magnetically Arrested Accretion on a Rapidly Spinning Black Hole
We describe global, 3D, time-dependent, non-radiative, general-relativistic, magnetohydrodynamic simulations of accreting black holes (BHs). The simulations are designed to transport a large amountExpand
On the Incidence of Strong Mg II Absorbers along Gamma-Ray Burst Sight Lines
We report on a survey for strong (rest equivalent width Wr ≥ 1 A), intervening Mg II systems along the sight lines to long-duration gamma-ray bursts (GRBs). The GRB spectra that comprise the surveyExpand
The Formation and Fragmentation of Primordial Molecular Clouds
Many questions in physical cosmology regarding the thermal history of the intergalactic medium, chemical enrichment, reionization, etc., are thought to be intimately related to the nature andExpand
Feedback in simulations of disc-galaxy major mergers
Using hydrodynamic simulations of disc-galaxy major mergers, we investigate the star formation history and remnant properties when various parametrizations of a simple stellar feedback model areExpand
EVIDENCE FOR LOW BLACK HOLE SPIN AND PHYSICALLY MOTIVATED ACCRETION MODELS FROM MILLIMETER-VLBI OBSERVATIONS OF SAGITTARIUS A
Millimeter very long baseline interferometry (mm-VLBI) provides the novel capacity to probe the emission region of a handful of supermassive black holes on sub-horizon scales. For Sagittarius A* (SgrExpand
Global optical/infrared-X-ray correlations in X-ray binaries: quantifying disc and jet contributions
The optical/near-infrared (OIR) region of the spectra of low-mass X-ray binaries appears to lie at the intersection of a variety of different emission processes. In this paper we presentExpand
