Using X-ray observations to identify the particle acceleration mechanisms in VHE SNRs and ``dark'' VHE sources
Pühlhofer, G.
Very high energy (VHE) γ-ray observations have proven to be very successful in localizing Galactic acceleration sites of VHE particles. Observations of shell-type supernova remnants have confirmed that particles are accelerated to VHE energies in supernova blast waves; the interpretation of the γ-ray data in terms of hadronic or leptonic particle …
A scientific case for XMM-Newton continuation
McBreen, B.; Schartel, N.
The presentations made at the workshop ``XMM-Newton: The Next Decade'', held at ESAC from 4th to the 6th of July 2007, contained an overwhelming amount of new results and well justified scientific questions that can be addressed by observations with XMM-Newton. XMM-Newton has over the next decade a solid scientific case. Given the high impact of X…
Planned and serendipitous surveys with XMM-Newton
Watson, M. G.
This article compares and contrasts the virtues of planned (and normally contiguous) surveys with XMM-Newton and the XMM-Newton serendipitous sky survey and discusses various ways in which both the quality and efficiency of contiguous surveys with XMM-Newton could potentially be improved.
Open questions on black hole binaries
Kaaret, P.
I discuss open questions regarding accreting black holes in binary systems, focusing on two questions: can we measure the spins of black holes and what is the nature of the ultraluminous X-ray sources. XMM-Newton could make significant strides in answering these questions and others over the next ten years. I suggest two observational programs des…
Searching for the missing baryons in the Warm-Hot Intergalactic Medium
Barcons, X.
At low redshift (z<2), almost half of the baryons in the Universe are not found in bound structures like galaxies and clusters and therefore most likely reside in a Warm-Hot Intergalactic Medium (WHIM), as predicted by simulations. Attempts to detect WHIM filaments at cosmological distances in absorption towards bright background sources have y…
Suzaku observations of clusters of galaxies
Matsushita, K.; Suzaku SWG Team
We review results of Suzaku observations of the intracluster medium of clusters of galaxies whose O, Mg, Si, S and Fe abundances have been measured with good accuracy due to the good energy resolution and low background. Metal mass-to-light ratios were derived and we will discuss the origin of the metals. We also review the results of the search f…
Statistical properties of galaxy clusters
Böhringer, H.
Galaxy clusters are important probes to test cosmological models and interesting large-scale laboratories for astrophysical phenomena. For both applications a precise knowledge of global cluster properties, especially their mass is important. X-ray observations provide still the best key for the evaluation of cluster properties and the description…
Supernova remnants, planetary nebulae and superbubbles: Prospects for new XMM-Newton observations
Decourchelle, A.
Important results achieved over the last years on supernova remnants, planetary nebulae and superbubbles are briefly reviewed in the context of X-ray observations. I intend to review the important open scientific questions in these fields, and the specific contributions that can be made by XMM-Newton.
The X-ray-infrared/submillimetre connection and the legacy era of cosmology
Alexander, D. M.
We review some recent results on the identification and characterisation of Active Galactic Nuclei (AGN) obtained by cross correlating X-ray surveys with infrared and submillimetre surveys. We also look toward the scientific gains that could be achieved from an XMM-Newton survey of the medium-deep legacy fields that are being observed at ≈ 1-850 &…
Thread safe astronomy
Seaman, R.
Observational astronomy is the beneficiary of an ancient chain of apprenticeship. Kepler's laws required Tycho's data. As the pace of discoveries has increased over the centuries, so has the cadence of tutelage (literally, "watching over"). Naked eye astronomy is thousands of years old, the telescope hundreds, digital imaging a few decades, but to…
