“…Rapid response to transient events, such as Novae, Dwarf Novae and X-ray transients, is of key importance to unveil changes in the physical conditions of accreted or ejected flows through the outburst evolution of the UV emission lines and continuum. Only very recently the onset of jets has also been identified in WDs accreting at high rate [61,62], suggesting that disc/jet coupling mechanism is ubiquitous in all types of binaries (BHs, NS and WDs). Also, the ratio of UV and X-ray luminosities is recently recognized as important discriminator between NS and BH binaries [52] and that FUV continuum could be affected by synchrotron emission from the jet.…”

“…For instance, alkali-doublet (AD) type transitions, the separation is proportional to α 2 . The Many Multiplets (MM) method compares many transitions from different multiplets, from different atoms/ions yielding uncertainties as low as ∆α/α≈ 10 -6 [29,104,61]. Indications of variations of α with redshift and location in space have been obtained from measurements of the resonance UV multiplets of Fe II, Ni II, Cr II, Zn II and Mg II [106].…”

“…These multiplets are observed in the visible range for redshifts z>1.6 henceforth, the current measurements have been obtained with 10-m class ground based telescopes. As shown in the figure, the measurements are very uncertain, especially because of the atmospheric effects (refraction index, sky lines, [61]). Measurements from space would be much more accurate provided that stable high resolution spectroscopy and a high collecting surface to reach z=2 is provided.…”

This contribution gathers the contents of the white paper submitted by the UV community to the Call issued by the European Space Agency in March 2013, for the definition of the L2 and L3 missions in the ESA science program. We outlined the key science that a large UV facility would make possible and the instrumentation to be implemented. The growth of luminous structures and the building blocks of life in the Universe began as primordial gas was processed in stars and mixed at galactic scales. The mechanisms responsible for this development are not wellunderstood and have changed over the intervening 13 billion years. To follow the evolution of matter over cosmic time, it is necessary to study the strongest (resonance) transitions of the most abundant species in the Universe. Most of them are in the ultraviolet (UV; 950 Å–3000 Å) spectral range that is unobservable from the ground. A versatile space observatory with UV sensitivity a factor of 50–100 greater than existing facilities will revolutionize our understanding of the Universe. Habitable planets grow in protostellar discs under ultraviolet irradiation, a by-product of the star-disk interaction that drives the physical and chemical evolution of discs and young planetary systems. The electronic transitions of the most abundant molecules are pumped by this UV field, providing unique diagnostics of the planet-forming environment that cannot be accessed from the ground. Earth’s atmosphere is in constant interaction with the interplanetary medium and the solar UV radiation field. A 50–100 times improvement in sensitivity would enable the observation of the key atmospheric ingredients of Earth-like exoplanets (carbon, oxygen, ozone), provide crucial input for models of biologically active worlds outside the solar system, and provide the phenomenological baseline to understand the Earth atmosphere in context

Figures de témoins: Médiations littéraires et fictionnelles du génocide des Tutsi au Rwanda

International audienceIn what way can the special position of witnesses from outside and witnesses of the aftermath that characterizes many writers who, in the space of twenty years, have devoted works to transmit the memory of the Tutsi genocide in Rwanda help redefine the notion of testimony, and above all, on what terms? To the extent that a media memory of the event (essentially in the form of images broadcast in the mass media in 1994) predates the work of writers, the idea is to question, from an ethical and aesthetic point of view, the potential of literary fiction to construct and transmit the memory of this event today. While updating some elements of a poethics [une poethique] of mediation, this paper also seeks to measure how, beyond the use of a style that can be described as iconic, certain literary works can attempt a true passing on of memory capable of crossing timeand boundaries between author and reader, others and myself, visible and invisible, conscious and unconscious, giving a new dimension to the issue of testimony

Murambi de Boubacar Boris Diop: L'écriture testimoniale comme transfiguration émotive du réel?

Cet essai vise à analyser Murambi . Le livre des ossements de Boubacar Boris Diop comme une œuvre de témoignage inspirée du génocide des Tutsi et Hutu modérés du Rwanda en 1994. Après un crime aussi odieux, il est nécessaire de dénoncer le mal et se souvenir des victimes. Cependant un véritable travail de mémoire consécutif à un crime de masse n'est possible qu'à la faveur d'une émotion politique qui désigne sans ambigüité victimes et bourreaux Nous voudrions attirer l'attention sur le contexte socio-politique qui a abouti à la production du roman pour mieux élucider les modalités d'écriture qui s'y déploient. Nous employons à dessein l'expression transfiguration émotive du réel pour parler des dispositions textuelles dont se sert l'œuvre d'art pour rendre compte de l'indicible souffrance des victimes du génocide, ceci dans un contexte socio-historique doublement marqué par les émotions: au plan social et politique. Il s'agit à terme de dire ce qui constitue la singularité de Murambi dans le vaste corpus des témoignages sur le génocide des Tutsi du Rwanda.
