XMM-Newton and Chandra combined analysis of the most massive galaxy clusters at z~1
XMM-Newton and Chandra combined analysis of the most massive galaxy clusters at z~1 Talk by Dr. Iacopo Bartalucci (CEA, Université Paris-Saclay)
Given at the Instituto de Astrofísica de Canarias on May 10th, 2018 10:30 AM We present a detailed study of the spatially resolved thermodynamic and hydrostatic mass profiles of the five most massive clusters detected at z~1 via the Sunyaev-Zel'dovich effect. These objects represent an ideal laboratory to test our models in a mass regime where structure formation is driven mainly by gravity. We present a method to study these objects that optimally exploits information from XMM-Newton and Chandra observations. The combination of Chandra’s excellent spatial resolution and XMM-Newton’s photon collecting power allows us to spatially resolve the profiles from the core to the outskirts, for the first time in such objects. Evolution properties are investigated by comparison with the REXCESS local galaxy cluster sample. Finally, we discuss the current limitations of this method in the context of joint analysis of future Chandra and XMM large programs and, more generally, of multi-wavelength efforts to study high redshift objects.

Deciphering Eta Carinae’s eruptive twin
ESA's XMM-Newton has spotted surprising changes in the powerful streams of gas from two massive stars in the binary star system HD 5980. One of the two stars had a major outburst reminiscent of the 19th-century eruption of Eta Carinae, and astronomers expected that its X-ray emission would fade gently over the years. Instead, they found the pair was two and a half times brighter than a decade earlier, and its X-ray emission was even more energetic, suggesting that colliding stellar winds don’t behave as expected.

Light Path Through XMM-Newton's Telescopes
Artist's impression of the XMM-Newton spacecraft. The animation shows how the light is collected by XMM-Newton's three telescopes through their entrance baffles. Within each telescope, the X-ray photons then pass a set of barrel-shaped coaxial mirrors (only a few of the actual 58 concentric mirrors are depicted). After grazing the gold-plated mirrors, the now focused X-ray photons are collected at the other end of the 10-meter-long spacecraft where the detectors of the EPIC  and RGS  instruments are located. The animation ends with a close-up of a telescope entrance baffle.  At the prime focus of each of the spacecraft's three telescopes, behind a six-position filter wheel, is a European Photon Imaging Camera (EPIC). With silicon chips that can register extremely weak X-ray radiation, these advanced Charge-Coupled Device cameras (CCD) are capable of detecting rapid variations in intensity, down to a thousandth of a second and less!  For a complementary analysis of the spectrum, two of the three telescopes have a grating structure on their mirror module that reflects about 40 per cent of the incoming rays to a secondary focus, with its own CCD camera. This Reflection Grating Spectrometer (RGS) "fans out" the various wavelengths, thus indicating, in more detail than EPIC, the exact condition of individual elements, such as oxygen and iron.

Supermassive Black Hole Wind Theory Proven by NASA & ESA!
NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) and ESA’s (European Space Agency) XMM-Newton telescope are showing that fierce winds from a supermassive black hole blow outward in all directions -- a phenomenon that had been suspected, but difficult to prove until now. http://proxyponder.com/2015/02/supermassive-black-hole-wind-theory-proven-by-nasa-and-esa/ Source: http://www.nasa.gov/press/2015/february/nasa-esa-telescopes-give-shape-to-furious-black-hole-winds/index.html#.VOa81fnF8uk Find Me & Follow Me: https://twitter.com/ShantiUniverse

Launch of XMM-Newton aboard Ariane 504, December 10 1999.
In this fifth episode of the [email protected]
vodcast series Rebecca Barnes will give us a glimpse of the hot, energetic and often violent Universe revealed through X-ray and gamma-ray astronomy, look at ESA missions that detect this hidden light and find out how the science that these missions perform is meticulously planned.
Centaurus A: The dark heart of a cosmic collision
Two of ESA's space observatories, XMM-Newton and Herschel, have combined to create a multi-wavelength view of violent events taking place within the giant galaxy of Centaurus A. The new observations strengthen the view that it may have been created by the cataclysmic collision of two older galaxies. New images taken with the Herschel space observatory with unprecedented resolution at far-infrared wavelengths show that the giant black scar of obscuring dust crossing the centre of Centaurus A all but disappears. ESA's XMM-Newton X-ray observatory recorded the high-energy glow from one of the jets, extending over 12 000 light years away from the galaxy's bright nucleus. XMM-Newton's X-ray view shows not only the way that the jet interacts with the surrounding interstellar matter, but also the galaxy's intensely active nucleus, and its large gaseous halo.
The Galactic Bulge as seen by XMM-Newton and INTEGRAL satellites
The central region of our Milky Way, the Galactic Bulge, is a rich host of variable high-energy X-ray and gamma-ray sources. Thanks to regular observations by XMM-Newton and Integral observatories over the last ten years, this dynamic environment has been charted in extensive detail, as revealed in this video.
A New View of an Icon: M16 in the Eagle Nebula
The Eagle Nebula as never seen before. In 1995, the Hubble Space Telescope's 'Pillars of Creation' image of the Eagle Nebula became one of the most iconic images of the 20th century. Now, two of ESA's orbiting observatories, XMM-Newton and Herschel satellites, have shed new light on this enigmatic star-forming region. The ESA Herschel Space Observatory's new image shows the pillars and the wide field of gas and dust around them. Captured in far-infrared wavelengths, the image allows astronomers to see inside the pillars and structures in the region. In parallel, a new multi-energy X-ray image from ESA's XMM-Newton telescope shows those hot young stars responsible for carving the pillars.
Astronomy Cast 276: XMM-Newton
Andromeda's coat of many colours
ESA's fleet of space telescopes has captured the nearby Andromeda Galaxy, also known as M31, in different wavelengths. Most of these wavelengths are invisible to the eye and each shows a different aspect of the galaxy's nature.
Visible light, as seen by optical ground-based telescopes and our eyes, reveals the various stars that shine in the Andromeda Galaxy, yet it is just one small part of the full spectrum of electromagnetic radiation. There are many different wavelengths that are invisible to us but which are revealed by ESA's orbiting telescopes. Starting at the long wavelength end, the Planck spacecraft collects microwaves. These show up particles of incredibly cold dust, at just a few tens of degrees above absolute zero. Slightly higher temperature dust is revealed by the shorter, infrared wavelengths observed by the Herschel space telescope. This dust traces locations in the spiral arms of the Andromeda Galaxy where new stars are being born today. The XMM-Newton telescope detects wavelengths shorter than visible light, collecting ultraviolet and X-rays. These show older stars, many nearing the end of their lives and others that have already exploded, sending shockwaves rolling through space. By monitoring the core of Andromeda since 2002, XMM-Newton has revealed many variable stars, some of which have undergone large stellar detonations known as novae. Ultraviolet wavelengths also display the light from extremely massive stars. These are young stars that will not live long. They exhaust their nuclear fuel and explode as supernovae typically within a few tens of millions of years after they are born. The ultraviolet light is usually absorbed by dust and re-emitted as infrared, so the areas where ultraviolet light is seen directly correspond to relatively clear, dust-free parts of Andromeda. By putting all of these observations together, and seeing Andromeda in its many different colours, astronomers are able to follow the life cycle of the stars.
XMM Newton: unveiling the universe
In 1895 German physicist Wilhelm Röntgen discovered rays which he didn't know much about, so he called them X-Rays. One of the best known applications for these rays today is medical imaging. In space scientists are interested in the sources of X-Rays. The ten year XMM Newton mission is the subject of this "Space" programme....
