Measuring the gas clumping in Abell 133

Andrea Morandi, Wei Cui

This paper continues a series in which we developed a non-parametric method to measure inhomogeneities in the gas distribution from X-ray observations of galaxy clusters. In this w…

Non-parametric method for measuring gas inhomogeneities from X-ray observations of galaxy clusters

Andrea Morandi, Daisuke Nagai, Wei Cui

We present a non-parametric method to measure inhomogeneities in the intracluster medium (ICM) from X-ray observations of galaxy clusters. Analysing mock Chandra X-ray observations…

Reconstructing three-dimensional parameters of galaxy clusters via multifrequency SZ observations

Andrea Morandi, Daisuke Nagai, Wei Cui

The Sunyaev-Zeldovich (SZ) effect is a promising tool to study physical properties of the hot X-ray emitting intracluster medium (ICM) in galaxy clusters. To date, most SZ observat…

VERITAS 2008 - 2009 monitoring of the variable gamma-ray source M87

The VERITAS Collaboration, V. A. Acciari, E. Aliu +84

M87 is a nearby radio galaxy that is detected at energies ranging from radio to VHE gamma-rays. Its proximity and its jet, misaligned from our line-of-sight, enable detailed morpho…
