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.
Radio Continuum Observations of the Candidate Supermassive Black Hole in the Dwarf Elliptical VCC 128
Pasquali, Anna; Seth, Anil; Debattista, Victor P. +4 more
The presence of black holes (BHs) at the centers of dwarf elliptical galaxies (dEs) has been argued both theoretically and observationally. Using archival HST WFPC2 data, we found the Virgo cluster dwarf elliptical galaxy VCC 128 to harbor a binary nucleus, a feature that is usually interpreted as the observable signature of a stellar disk orbitin…
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.
X-Ray Spectroscopy of SN1006 with Suzaku
Yamaguchi, H.; Koyama, K.; Bamba, A.
We report the Suzaku results on the structures of the thermal plasmas and non-thermal emissions from SN 1006, a type Ia supernova remnant. Clear evidence for a type Ia SNR is found in the metal abundances of the ejecta. Stringent constraint on the maximum electron energy and the synchrotron loss time are given from the non-thermal spectrum.
a New View of the Sun from the Hinode Space Mission
Harra, Louise K.
The Japanese/US/UK space mission, Hinode, was launched successfully in September 2006. Now, more than a year after the commissioning of the spacecraft and instruments, Hinode is unveiling a new view of the Sun. Hinode's goal is to help us to understand solar activity, and to link activity on (and below) the surface to the outer corona. This review…
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 &…
