Yves Bonnefoy traduttore di Shakespeare: il poeta e la prova del dialogo

Contemporary French poet Yves Bonnefoy has always been attracted by English poetry, especially by Shakespeare’s work. Translating Shakespeare’s plays and sonnets has been a fundamental experience for him. The contact with a different culture, a different language and a different sort of poetry has been an important moment in his poetic experience. The dialogue between the French and the Elizabethan poet, which started in the 1950s, hasn't stopped yet and it offers some interesting perspectives to study Bonnefoy's work from a new point of view. Translation – which is first of all a poetic experience to him – is in fact the chance to get in touch with somebody else's poetry and to establish a dialogue with his poetic universe. Such a dialogue requires on the one hand an ‘ethic’ attitude on the translator's part, that is an attentive listening and a deep understanding of the original text. However, Bonnefoy has to create a new ‘poetic’ text in his own language. This is why the ‘seeds’ of his own poetry are also present in his translated texts, in which it is possible to clearly distinguish both the presence of the French poet’s own voice and his attempt to open his ‘speech’ to the specific quality of the Shakespearean poetry. On the other hand, such a deep contact with Shakespeare's work has changed the French poet, contributing to the development and maturity of his own poetry. Indeed, the Elizabethan poet is present in his work in different ways, in his critical essays as well as in his poems. Against this background, the aim of the present study is to define the complex dialogic forms and the osmotic relationships between the poetic experience and the experience of translation, which are considered two different moments of the same ontological research by the French poet.

Strong semiclassical gravity in the universe and the laboratory

Three published papers are resumed in this thesis. Different aspects of the semiclassical theory of gravity are discussed. In chapter 1 we find a new perturbative (yet analytical) solution to the unsolved problem of the metric junction between two Friedmann-Robertson-Walker using Israel's formalism. The case of an expanding radiation core inside an expanding or collapsing dust exterior is treated. This model can be useful in the "landscape" cosmology in string theory or for treating new gravastar configurations. In chapter 2 we investigate the possible use of the Kodama vector field as a substitute for the Killing vector field. In particular we find the response function of an Unruh detector following an (accelerated) Kodama trajectory. The detector has finite extension and backreaction is considered. In chapter 3 we study the possible creation of microscopic black holes at LHC in the brane world model. It is found that the black hole tidal charge has a fundamental role in preventing the formation of the horizon.

The Universe 10 Billion years ago: Morphologies, Star-formation rates and Galactic-scale winds in z ∼ 2 Galaxies

This thesis is devoted to the study of the properties of high-redsfhit galaxies in the epoch 1 < z < 3, when a substantial fraction of galaxy mass was assembled, and when the evolution of the star-formation rate density peaked. Following a multi-perspective approach and using the most recent and high-quality data available (spectra, photometry and imaging), the morphologies and the star-formation properties of high-redsfhit galaxies were investigated. Through an accurate morphological analyses, the built up of the Hubble sequence was placed around z ~ 2.5. High-redshift galaxies appear, in general, much more irregular and asymmetric than local ones. Moreover, the occurrence of morphological k-­correction is less pronounced than in the local Universe. Different star-formation rate indicators were also studied. The comparison of ultra-violet and optical based estimates, with the values derived from infra-red luminosity showed that the traditional way of addressing the dust obscuration is problematic, at high-redshifts, and new models of dust geometry and composition are required. Finally, by means of stacking techniques applied to rest-frame ultra-violet spectra of star-forming galaxies at z~2, the warm phase of galactic-scale outflows was studied. Evidence was found of escaping gas at velocities of ~ 100 km/s. Studying the correlation of inter-­stellar absorption lines equivalent widths with galaxy physical properties, the intensity of the outflow-related spectral features was proven to depend strongly on a combination of the velocity dispersion of the gas and its geometry.
