Abstract:

In this thesis I present an in-depth study of the distribution of various neutral species in Titan’s upper atmosphere, at altitudes between 950 and 1,500 km for abundant species (N₂, CH₄ as well as their isotopes) and between 950 and 1,200 km for most minor species. However, the study of the H2 distribution on Titan is extended to an altitude as high as 6,000 km in the exosphere. The analysis is based on a large sample of Cassini/INMS (Ion Neutral Mass Spectrometer) measurements in the CSN (Closed Source Neutral) mode, obtained during 15 close flybys of Titan. The densities of abundant species

Abstract:

A major application of tandem mass spectrometry is the study of gas-phase ion chemistry. Gas-phase ion chemistry involving ion thermochemistry and ion dissociation characteristics, is one of the foundations of analytical chemistry. A signal (peak) in a mass spectrum is only identified by its mass-to-charge ratio (m/z) and may represent several isomeric ions. Isomeric species having the same element composition can be distinguished by tandem mass spectrometry. An investigation of isomeric (C,H$\sb3,$N,O) $\sp{+-}$ ions provides such an example, where four isomeric ions ( (H$\sb2$NC(H)O) $\sp{+-

Abstract:

The question of physics beyond the Standard Model remains as crucial as it was before the discovery of a Higgs boson at the Large Hadron Collider, as the theoretical and experimental shortcomings of the Standard Model remain unresolved. Indeed, theoretical problems such as the hierarchy of energy scales, the Higgs mass fine-tuning and the large number of postulated parameters need to be addressed, while the experimental observations of dark matter, dark energy and neutrino masses are not explained by the Standard Model. Many hypotheses addressing these issues predict the existence of new neutr

Abstract:

HCN is an important constituent in Titan's upper atmosphere, serving as the main coolant in the local energy budget. In this study, we derive the HCN abundance at the altitude range of 960-1400 km, combining the Ion-Neutral Mass Spectrometer data acquired during a large number of Cassini flybys with Titan. Typically, the HCN abundance declines modestly with increasing altitude and flattens to a near constant level above 1200 km. The data reveal a tendency for dayside depletion of HCN, which is clearly visible below 1000 km but weakens with increasing altitude. Despite the absence of convincing

Abstract:

Neutron stars (NS) are the most compact objects that can be directly observed. They can be used to study properties of matter at supranuclear densities. This in turn gives us information to separate between numerous theoretical equations of states of dense matter. Thermonuclear (type-I) X-ray bursts from low mass X-ray binaries can be used to address this issue. Some of these bursts can be so energetic that they cause the whole photosphere of the NS to expand. The cooling of these photospheric radius expansion bursts can be compared to theoretical atmosphere models to obtain the mass and radiu

However, new applications are nowadays developed involving neutron-induced fission in this energy domain.

A novel application of ionic liquid as a charge carrier for the analysis and detection of neutral organometallic complexes using a mass spectrometer has been presented.

Abstract:

<p> Kilohertz quasi-periodic oscillations or kHz QPOs are X-ray intensity variations observed in neutron star low-mass X-ray binary (LMXB) systems. In such systems, matter is transferred from a secondary low-mass star to a neutron star via the process of accretion. kHz QPOs occur on the timescale of the inner accretion flow and may carry signatures of the physics of strong gravity (<i>c<sup>2</sup> ~ GM/R</i>) and possibly clues to constraining the neutron star equation of state (EOS). No model to date has been able to illuminate the origin of kHz QPOs. Spectral-timing is a set of analysis tec

Abstract:

It has been established that regardless of the fact that journalism in not a one-gender- profession anymore, news is still defined from a male perspective. A number of studies through the years examined the news content and determined that it continued male.Though news veterans acknowledge significant changes in m coming of women to the newsrooms, those changes sometimes are hard to detect on the personal level. Male and female reporters claim that even though gender can affect their approach to reporting, the final product they produce does not have gender marked on it. The present Q study is

Abstract:

Cette thèse porte sur l’étude de la production de surface des ions négatifs (IN) pour des applications dans la fusion thermonucléaire. Ce travail a été réalisé à l'aide d'une source plasma PHISIS. Les IN formés en surface de l'échantillon sont collectés et analysés avec un spectromètre de masse (SM). La fonction de la distribution en énergie des ions négatifs FDEIN est mesurée. Dans cette thèse, une technique de polarisation DC pulsée est introduite pour permettre l'étude de la production d'IN en surface sur des échantillons isolants comme le diamant. Un modèle qui calcule le taux de changemen
