Résumé :

This thesis presents the results from the Chandra Deep Group Survey, a survey dedicated to find high redshift groups of galaxies in deepest observations available in the Chandra archive. The catalogue compiled from this survey contains 26 groups and 36 clusters with available redshifts, with largest redshift being 1.3. This sample has been used to investigate the evolution of the thermal state of the gas at the centre of groups and compare this evolution to that of clusters. Different parameters have been used to quantify the strength of cool cores and it has been showed that groups and cluste

Résumé :

<p> Studies of scaling relations in groups and clusters of galaxies have shown that the X-ray properties of groups deviate the most from the self-similar prediction. This is because groups are more affected by non-gravitational processes due to their shallower potential well, a behaviour which makes groups an ideal class of systems for the study of the impact of feedback. From the observational point of view, the study of the X-ray properties of groups, especially at high redshifts is hindered by their lower surface brightness compared to their more massive counterparts. We present the result

This thesis presents the results from photometric time-series observations of Jupiter-family comets (JFCs). A method was developed that allows mutual absolute photometric calibration of data taken at different epochs with different instruments and results in absolute-calibration uncertainty of ∼0.02 mag. The method was applied to various datasets with the goal of studying the rotation rates and surface properties of ten comets. Previously published properties of JFCs were collected and complemented by new results. The resulting comprehensive sample was used to study the ensemble properties of

Résumé :

It has been long known that galaxy properties are strongly connected to their environment; however, a complete picture is still missing. This work's aim is to better understand the role of environment in shaping the galaxy properties, using a sample of 25 redshift-selected galaxy groups at 0.060 < z < 0.063, for which 30 multi-wavelength parameters are available. Given the wide variety of group dynamical states, it was fundamental to try and identify different classes of groups performing a statistical clustering analysis using all the available parameters independently of their physical meani

An experimental investigation has been undertaken in an attempt to determine the mechanism of formation of anomalous eutectics. A melt fluxing method and a drop tube technique have been used to undercool eutectic Ag-Cu alloy. During the fluxing experiments, the growth fronts of the undercooled alloy samples have been monitored using high speed camera imaging. The evolved microstructures of the fluxed samples undercooled ≤ 60 K exhibit a trizonal structure consisting of mixed anomalous and lamellar eutectic. The high speed camera imaging reveals that the growth front propagates in a spasmodic m

This thesis is comprised of X-ray and optical studies of 27 X-ray selected galaxy clusters from the XMM-LSS survey. These systems are mostly groups and poor clusters, with temperatures 0.6-4.8 keV, spanning the redshift range 0.05 to 1.05, hence these are some of the highest redshift X-ray selected clusters to have been studied. In the X-ray study, the evolution in the X-ray surface brightness profiles of the hot intracluster plasma is studied. Comparing the profiles with a standard -model it is found that 54% of the sample possess cuspy (cool) cores. Trends with both temperature and redshift

In-situ temperature measurements during welding were carried out by placing thermocouples at different locations from the weld interface.

They attributed this surprising effect to the combination of precipitation strengthening mechanism and TRIP effect of reverted/retained austenite.

Résumé :

The chemistry of large carbon-containing molecules in space is widely researched with notable advances including understanding of the aromatic infrared emission features in terms of their general origin in polycyclic aromatic hydrocarbon (PAH) molecules, identification of the fullerenes C60 and C70 as the largest molecules detected in the interstellar medium, and knowledge of the structure and composition of various solid-state interstellar grains. However, there remain major challenges. The work described in this Thesis addresses some longstanding, unanswered questions in astrochemistry, such
