description: We present optical and near-infrared spectroscopic observations of the optical Einstein ring 0047-2808. We detect both [OIII] lines 4959, 5007 near 2.3 micron, confirming the redshift of the lensed source as z=3.595. The Ly-a line is redshifted relative to the [OIII] line by 140+-20 km/s. Similar velocity shifts have been seen in nearby starburst galaxies. The [OIII] line is very narrow, 130 km/s FWHM. If the ring is the image of the centre of a galaxy the one-dimensional stellar velocity dispersion sigma=55 km/s is considerably smaller than the value predicted by Baugh et al. (1998) for the somewhat brighter Lyman-break galaxies. The Ly-a line is significantly broader than the [OIII] line, probably due to resonant scattering. The stellar central velocity dispersion of the early-type deflector galaxy at z=0.485 is 250+-30 km/s. This value is in good agreement both with the value predicted from the radius of the Einstein ring (and a singular isothermal sphere model for the deflector), and the value estimated from the D_n-sigma relation.

description: The project ”Waves and turbulence on wavy coastal seabeds inducing vertical scalar transport” is part of the graduate school Baltic Transcoast. This graduate school aimed to investigate the interaction between a coastal fen and the Baltic sea. In this work, the mixing and transport of the submarine groundwater discharge (SGD) was investigated in a defined laboratory experiment. For this, a new wave channel ground model was constructed and produced to facilitate the variation of different parameters for the investigations.
Catalytic and Sorption Measurements Using Flux Response Technology
Creators: name: Sasegbon, Ayodeji Oladipo
Publisher: name: Imperial College London
Year: 2014

description: Advancements in characterisation techniques in the field of heterogeneous catalysis have been explored, in particular the powerful in situ perturbation method, Flux Response Technology (FRT). The adaptation of FRT as a novel in situ perturbation technique in gas sorption measurements continues to yield consistent results with literature values. This is made possible because FRT measures miniscule changes in transient flows in the order of 10-2 μl/min for gaseous processes involving a change in volume (dV/dt). These changes are measured directly by a very sensitive differential pressure transducer (DPT) in a pneumatic system analogous to an electrical Wheatstone bridge assembly, whereby gas molecules replace electrons and capillaries function as resistors. By showing the successful incorporation of the measurements of adsorption capacities and diffusivity coefficients in the same experimental window, FRT’s use as a bolt-on technology for the rapid screening of catalyst material has been highlighted. The technique possesses a distinct advantage in requiring no prior calibrations to the system, enabling the analysis of a broad spectrum of materials and gases. The FRT technique also features a unique ability in being able to act as a dual flowrate and composition detector through the use of carefully calculated delay lines to separate changes in flowrate caused by perturbations of concentration and changes in composition. The FRT technique provides a quick, simple, accurate, and inexpensive method of characterising material properties in situ in heterogeneous catalysis. Several studies into the dynamics of gas sorption processes utilising FRT measurements on adsorbents were undertaken in the completion of this PhD. The diffusivity parameters of propane in varying alumina/CeZrOx washcoats of Cordierite monoliths were investigated under isothermal conditions. A novel method of analysing FRT derived response profiles with the Zero Length Column (ZLC) model was established and reported on. The diffusion coefficients obtained were consistent with previously reported macroscopic data and compared well when evaluating the structural differences of the washcoats of each sample (Granato et al., 2010). The dynamics of ammonia sorption on commercially available zeolites with varying SiO2/Al2O3 ratios was analysed to investigate the total acidity of these zeolites. The dynamics of carbon dioxide sorption were also investigated to analyse the total basicity of the same zeolite samples. Process optimisations were conducted to obtain an ultra fast isotherm measurement technique for the analysis of nitrogen sorption on aluminium oxides with varying surface areas at 77 K. Finally, insights into the development of a dynamic parallel performance testing (DPPT) FRT setup were undertaken to directly compare the activities of catalytic material operating side by side.

description: A block lower triangular Toeplitz system arising from time-space fractional diffusion equation is discussed. For efficient solutions of such the linear system, the preconditioned biconjugate gradient stabilized method and flexible general minimal residual method are exploited. The main contribution of this paper has two aspects: (i) A block bi-diagonal Toeplitz preconditioner is developed for the block lower triangular Toeplitz system, whose storage is of $\mathcal{O}(N)$ with $N$ being the spatial grid number; (ii) A new skew-circulant preconditioner is designed to fast calculate the inverse of the block bi-diagonal Toeplitz preconditioner multiplying a vector. Numerical experiments are given to demonstrate the efficiency of our preconditioners.

description: Quadrature squeezing of light is investigated in a hybrid atom-optomechanical system comprising a cloud of two-level atoms and a movable mirror mediated by a single-mode cavity field. When the system is at high temperatures with quadrature fluctuations of light much above the standard quantum limit (SQL), excitation counting on the collective atomic state can effectively reduce the light noise close to the SQL. When the system is at low temperatures, considerable squeezing of light below the SQL is found at steady state. The squeezing is enhanced by simply increasing the atom-light coupling strength with the laser power optimized close to the unstable regime, and further noise reduction is achieved by decreasing various losses in the system. The presence of atoms and excitation counting on the atoms lessen the limitation of thermal noise, and the squeezing can be achieved at environment temperature of the order K. The nonclassicality of the light, embodied by the negative distributions of the Wigner function, is also studied by making non-Gaussian measurements on the atoms. It is shown that with feasible parameters excitation counting on the atoms is effective in inducing strongly optical nonclassicality.

description: We present a semi-analytic model for self-consistently evolving a population of globular clusters (GCs) in a given host galaxy across cosmic time. We compute the fraction of GCs still hosting intermediate-mass black holes (IMBHs) at a given redshift in early and late type galaxies of different masses and sizes, and the corresponding rate of tidal disruption events (TDEs), both main-sequence (MS) and white dwarf (WD) stars. We find that the integrated TDE rate for the entire GC population can exceed the corresponding rate in a given galactic nucleus and that $\sim 90$% of the TDEs reside in GCs within a maximum radius of $\sim 2-15$ kpc from the host galaxy's center. This suggests that observational efforts designed to identify TDEs should not confine themselves to galactic nuclei alone, but should also consider the outer galactic halo where massive old GCs hosting IMBHs would reside. Indeed, such off-centre TDEs as predicted here may already have been observed. MS TDE rates are more common than WD TDE rates by a factor 30 (100) at $z\leq 0.5$ ($z=2$). We also calculate the rate of IMBH-SBH mergers across cosmic time, finding that the typical IMRI rate at low redshift is of the order of $\sim 0.5-3$ Gpc$^{-3}$ yr$^{-1}$, which becomes as high as $\sim 100$ Gpc$^{-3}$ yr$^{-1}$ near the peak of GC formation. Advanced LIGO combined with VIRGO, KAGRA, ET and LISA will be able to observe the bottom-end and top-end of the IMBH population, respectively.

description: We present an optical imaging study of 20 southern-sky nova remnants which has resulted in the discovery of four previously unknown nova shells -- V842 Cen, RR Cha, DY Pup and HS Pup. The study has also revealed previously unobserved features in three other known shells -- those of BT Mon, CP Pup and RR Pic. The images of BT Mon, V842 Cen, RR Cha, DY Pup and HS Pup have been processed using several deconvolution algorithms (Richardson-Lucy, maximum entropy and clean) in addition to straightforward point-source subtraction in an attempt to resolve the shells from the central stars. The use of four different methods enables us to make a qualitative judgement of the results. Notably, the shell of RR Pic displays tails extending outwards from clumps in the main ejecta similar to those previously detected in DQ Her.

The method analyzes combinations of subsets in the data set in a Bayesian model comparison way, potentially finding outliers, subsets of data affected by systematics or new physics. In order to validate our analysis and assess its sensitivity we performed several cross-checks, for example by removing some of the data or by adding artificially contaminated points, while we also generated mock data sets in order to estimate confidence regions of the iR. Applying this methodology, we found no anomalous behavior in the $fσ_8(z)$ data set, thus validating its internal robustness.

description: Defects, both intrinsic and hydrogen-induced, are commonplace in electrochemical processes, particularly in catalysis where hydrogen can penetrate the catalysts and influence chemical reactions. Palladium (Pd), renowned for its high hydrogen permeability, forms defects upon exposure to hydrogen. Herein, we investigate various defective Pd-surfaces containing missing row, vacancy, and adatom defects, and their interplay with hydrogen atoms to enhance our understanding of Pd-based catalysts during hydrogenation reactions or with Pd as a cathode. Low-index defective surfaces and various hydrogen (H) coverages are explored to construct surface Pourbaix diagrams (SPD) and study their H-termination at specific pH and potential. The SPDs show increased hydrogen adsorption upon lowering the electrode potential. The stability of defective surfaces follows Pd’(110) > Pd’(100) > Pd’(111), in contrast to the stability trend observed for pristine surfaces, Pd(111) > Pd(100) > Pd (110). This reversal is attributed to the tendency of ‘less stable’ open surfaces, such as Pd(110), to reconstruct, or be stabilized by hydrogen. Our study emphasizes the importance of hydrogen sublayers in stabilizing H-covered defective surfaces, which facilitates the formation of Pd vacancies in the sublayers. Our work is essential to advance catalysis and surface science, as it provides valuable insights into material restructuring under elec?trocatalytic environments.

description: A new class of polyimides had been synthesized from a novel aromatic diamine, 2',7'-bis(4-aminophenoxy)-spiro(4,5-diazafluoren-9,9'-xanthene). Polyimides were prepared by two-stage polycondensation of diamine monomer with various aromatic dianhydride. These polymers showed good thermal stability, solubility and optical transparency. These polymers showed good thermal stability, solubility and optical transparency. Except 6a, all polyimides were dissolved in aprotic polar solvents at room temperature. The glass transition temperatures (Tg) of the poly(ether imide)s were determined to be 338–423 °C and 345–428 °C by dynamic mechanical thermal analyses (DMA) and differential scanning calorimeter (DSC), respectively. Decomposition temperature for 10% weight loss all of these poly(ether imide)s above 560 °C in both nitrogen and air atmospheres. Normalized transparencies in the visible region (400–780 nm) were recorded between 67% and 83%. The dielectric constants of polyimide film were recorded in the range of 2.56–3.12 at 1 KHz.

description: We measure the anisotropic midinfrared response of electrons and phonons in bulk YBa2Cu3O7-δ after femtosecond photoexcitation. A line shape analysis of specific lattice modes reveals their transient occupation and coupling to the superconducting condensate. The apex oxygen vibration is strongly excited within 150 fs, demonstrating that the lattice absorbs a major portion of the pump energy before the quasiparticles are thermalized. Our results attest to substantial electron-phonon scattering and introduce a powerful concept probing electron-lattice interactions in a variety of complex materials.

description: Financial derivatives are contracts that can have a complex payoff dependent upon underlying benchmark assets. In this work, we present a quantum algorithm for the Monte Carlo pricing of financial derivatives. We show how the relevant probability distributions can be prepared in quantum superposition, the payoff functions can be implemented via quantum circuits, and the price of financial derivatives can be extracted via quantum measurements. We show how the amplitude estimation algorithm can be applied to achieve a quadratic quantum speedup in the number of steps required to obtain an estimate for the price with high confidence. This work provides a starting point for further research at the interface of quantum computing and finance.

Warm absorbers in active galactic nuclei

Year: 1995
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Recent {\it ASCA} observations confirm the presence of X-ray absorption due to partially ionized gas in many Seyfert 1 galaxies; the so-called warm absorber. Constraints on the location of the warm material are presented with the conclusion that this material lies at radii coincident with, or just outside, the broad-line region. The stability of this warm material to isobaric perturbations under the assumptions of thermal and photoionization equilibrium is also studied. It is shown that there is a remarkably small range of ionization parameter, $ξ$, for which the warm absorber state is stable. The robustness of this result to changes in the shape of the primary continuum, the assumed density and optical depth is investigated. Given the constraints on the location and the stability properties of the material, several models for the environments of Seyfert nuclei are discussed. These attempt to explain the presence of significant amounts of partially ionized material. In particular, various models of the broad-line region are discussed. The simple two-phase model of the broad-line region proves to be unsatisfactory. A model of the broad-line region is presented in which a turbulent, hot intercloud medium is mechanically heated. Turbulent mixing layers could then give rise to warm absorption features. Finally, a model is discussed in which the warm absorber is due to a steady state, radiatively driven outflow.

On Homoclinic Orbits to Center Manifolds in Hamiltonian Systems
Creators: name: Giles, William
Publisher: name: Imperial College London
Year: 2014

description: The objects of study in this thesis are Hamiltonian systems of ordinary differential equations possessing homoclinic orbits. A homoclinic orbit is a solution of the system which converges to the same invariant set as time approaches both positive and negative infinity. In our case, the invariant set in question is assumed to be a nonhyperbolic equilibrium state. Such an equilibrium state possesses a center manifold, containing all orbits which remain close to the equilibrium. We are concerned with finding orbits which converge to orbits in the center manifold in both time directions. We consider firstly the case in which the nonhyperbolic eigenvalues at the equilibrium consist of pairs of nonzero purely imaginary eigenvalues. We study the set of homoclinics to the center manifold by constructing an operator on a suitable function space whose zeros correspond to homoclinics. We use a Lyapunov-Schmidt technique to reduce the problem to that of studying the zero set of a real-valued function defined on the center manifold, which has a critical point at the origin. A formula is found for the Hessian matrix at this critical point, involving the so called scattering matrix. Under nonresonance and nondegeneracy conditions, we characterise the possible Morse indices of the Hessian, permitting an application of the Morse lemma to describe the set of homoclinics. We also consider special cases, including reversible systems. We then consider a more geometric approach to the problem, allowing us to define a nonlinear analogue of the scattering matrix using stable and unstable foliations of the invariant manifolds. We use this approach to unfold the system in parametrised families - we consider here also the case of a two dimensional center manifold corresponding to zero eigenvalues - bifurcation diagrams are produced for homoclinics to the origin in this case. The effects of additional reversible structure are again considered.

description: In modern socio-cultural conditions, a significant update of the philosophical concept of the modern city as a subject of self-consciousness and culture is becoming more and more popular. The constructiveness of the idea of a noospheric city as an alternative to the traditional concept of functionality, set on the basis of the development of technology and digital-information culture, is justified. The philosophy of the impression economy, its categorical apparatus, strategic lines of development, tools and applications are considered as a methodological basis for the formation of a noospheric city. The model of the noospheric city in the context of the impression economy shows the nature of information and communication, axiological, ethical, and aesthetic connections and reveals their specifics and functions.
Nonlinear adaptive estimation with application to sinusoidal identification
Creators: name: Chen, Boli
Publisher: name: Imperial College London
Year: 2015

description: Parameter estimation of a sinusoidal signal in real-time is encountered in applications in numerous areas of engineering. Parameters of interest are usually amplitude, frequency and phase wherein frequency tracking is the fundamental task in sinusoidal estimation. This thesis deals with the problem of identifying a signal that comprises n (n ≥ 1) harmonics from a measurement possibly affected by structured and unstructured disturbances. The structured perturbations are modeled as a time-polynomial so as to represent, for example, bias and drift phenomena typically present in applications, whereas the unstructured disturbances are characterized as bounded perturbation. Several approaches upon different theoretical tools are presented in this thesis, and classified into two main categories: asymptotic and non-asymptotic methodologies, depending on the qualitative characteristics of the convergence behavior over time. The first part of the thesis is devoted to the asymptotic estimators, which typically consist in a pre-filtering module for generating a number of auxiliary signals, independent of the structured perturbations. These auxiliary signals can be used either directly or indirectly to estimate—in an adaptive way—the frequency, the amplitude and the phase of the sinusoidal signals. More specifically, the direct approach is based on a simple gradient method, which ensures Input-to-State Stability of the estimation error with respect to the bounded-unstructured disturbances. The indirect method exploits a specific adaptive observer scheme equipped with a switching criterion allowing to properly address in a stable way the poor excitation scenarios. It is shown that the adaptive observer method can be applied for estimating multi-frequencies through an augmented but unified framework, which is a crucial advantage with respect to direct approaches. The estimators’ stability properties are also analyzed by Input-to-State-Stability (ISS) arguments. In the second part we present a non-asymptotic estimation methodology characterized by a distinctive feature that permits finite-time convergence of the estimates. Resorting to the Volterra integral operators with suitably designed kernels, the measured signal is processed, yielding a set of auxiliary signals, in which the influence of the unknown initial conditions is annihilated. A sliding mode-based adaptation law, fed by the aforementioned auxiliary signals, is proposed for deadbeat estimation of the frequency and amplitude, which are dealt with in a step-by-step manner. The worst case behavior of the proposed algorithm in the presence of bounded perturbation is studied by ISS tools. The practical characteristics of all estimation techniques are evaluated and compared with other existing techniques by extensive simulations and experimental trials.

On the development and implementation of high-order flux reconstruction schemes for computational fluid dynamics
Creators: name: Witherden, Freddie
Publisher: name: Imperial College London
Year: 2015

description: High-order numerical methods for unstructured grids combine the superior accuracy of high-order spectral or finite difference methods with the geometric flexibility of low-order finite volume or finite element schemes. The Flux Reconstruction (FR) approach unifies various high-order schemes for unstructured grids within a single framework. Additionally, the FR approach exhibits a significant degree of element locality, and is thus able to run efficiently on modern streaming architectures, such as graphics processing units (GPUs). The aforementioned properties of FR mean it offers a promising route to performing affordable, and hence industrially relevant, scale-resolving simulations of hitherto intractable unsteady flows within the vicinity of real-world engineering geometries. In this thesis a formulation of the FR approach that is suitable for solving non-linear advection-diffusion type problems on mixed curvilinear grids is developed. Issues around aliasing are explored in detail and techniques for mitigation outlined. A methodology for identifying symmetric quadrature rules inside of a variety of domains is also presented and used to find several rules that appear to be an improvement over those in literature. This methodology is also used to obtain improved sets of solution points inside of triangular elements. PyFR, an open-source Python based framework for solving the compressible Navier–Stokes equations using the FR approach, is also developed. It is designed to target a range of hardware platforms via use of an in-built domain specific language based on the Mako templating engine. PyFR is able to operate on mixed grids in both two and three dimensions and can target NVIDIA GPUs, AMD GPUs, and Intel CPUs. Results are presented for various benchmark flow problems, single-node performance is discussed, heterogeneous multi-node capabilities are analysed, and scalability is demonstrated on up to 2000 NVIDIA K20X GPUs for a sustained performance of 1.3 PFLOP/s.

We illustrate how three-body pseudopotentials (PPs) can be readily computed from the analytical expressions for a wide variety of different systems, and show that for realistic systems, softening the bare Coulomb interactions (e.g. finite thickness or screening) can significantly suppress three-body interactions. More interestingly, for experimental systems without Galilean invariance (which is common for real materials), there is strong evidence that higher orders in band dispersion can drive the Moore-Read state from anti-Pfaffian to Pfaffian phase. Our analysis points to the importance of the realistic band structure details to the non-Abelian topological phases, and the analytical expressions we derived can also be very useful for high fidelity numerical computations.

description: We have investigated the properties of a complete K-band selected sample of 35 elliptical and S0 galaxies brighter than K=20.15 in the Hubble Deep Field, as representative of the field galaxy population. This sample has been derived from deep K-band image by the KPNO-IRIM camera, by applying a rigorous morphological classification scheme based on quantitative analyses of the surface brightness profiles. The broad-band spectra of the sample galaxies allow us to date their dominant stellar populations. The majority of bright early-types in this field are found at redshifts z<1.3 to display colors indicative of a fairly wide range of ages (typically 1.5 to 3 Gyrs). We find that the major episodes of star-formation building up typical M_star galaxies have taken place during a wide redshift interval 11.3, which should be detectable during the luminous star-formation phase expected to happen at these redshifts. Obvious solutions are a) that the merging events imply perturbed morphologies which prevent selecting them by our morphological classification filter, or b) that a dust-polluted ISM obscures the (either continuous or episodic) events of star-formation. We conclude that the likely solution is a combination thereof, i.e. a set of dust-enshrouded merging-driven starbursts occurring during the first few Gyrs of the galaxy's lifetime.

description: We explore the ability of gravitational-wave detectors to extract the redshift distribution of binary black hole (BBH) mergers. The evolution of the merger rate across redshifts $0 < z \lesssim 1$ is directly tied to the formation and evolutionary processes, providing insight regarding the progenitor formation rate together with the distribution of time delays between formation and merger. Because the limiting distance to which BBHs are detected depends on the masses of the binary, the redshift distribution of detected binaries depends on their underlying mass distribution. We therefore consider the mass and redshift distributions simultaneously, and fit the merger rate density, ${dN}/{dm_1\,dm_2\,dz}$. Our constraints on the mass distribution agree with previously published results, including evidence for an upper mass cutoff at $\sim 40 \ M_\odot$. Additionally, we show that the current set of six BBH detections are consistent with a merger rate density that is uniform in comoving volume. Although our constraints on the redshift distribution are not yet tight enough to distinguish between BBH formation channels, we show that it will be possible to distinguish between different astrophysically motivated models of the merger rate evolution with $\sim 100$--$300$ LIGO-Virgo detections (to be expected within 2--5 years). Specifically, we will be able to infer whether the formation rate peaks at higher or lower redshifts than the star formation rate, or the typical time delay between formation and merger. Meanwhile, with $\sim 100$ detections, the inferred redshift distribution will place constraints on more exotic scenarios such as modified gravity.

Quantifying the spatial and temporal response of UTH and OLR to deep convection over Tropical Africa
Creators: name: Ingram, James
Publisher: name: Imperial College London
Year: 2015

description: Upper Tropospheric Humidity (UTH) has a strong control on clear-sky Outgoing Longwave Radiation (OLR). Moisture from the boundary layer is transported to the drier upper troposphere by convective ascent in the tropics and realised in the form of deep convective clouds. The spatial and temporal response of UTH and the corresponding OLR are cause for debate. This study uses geostationary satellite imagery from the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) to estimate UTH using water vapour channel radiances. Deep convection over Tropical Africa is detected using the difference between 6.2 mm and 7.3 mm brightness temperatures. The sensitivity of TOA brightness temperatures to cloud properties including cloud top height and optical depth are modelled using the Santa Barbara Disort Atmospheric Radiative Transfer model with thresholds developed using colocated matchups with CloudSat and CALIPSO cloud classifications. The most appropriate thresholds are determined using probability statistics and receiver operating characteristic curves. Deep convective clouds are tracked over their lifetime in June and December 2010 using a cloud tracking algorithm, based on an area overlap method. A general robust pattern in the UTH response emerges. A stronger response of UTH is found in the spatial domain than that over the temporal domain. UTH decreases with distance from the cloud edge, whilst a small increase is seen over the cloud lifetime. This was found to be controlled by cloud size and cloud lifetime, with larger and longer lived clouds causing a stronger perturbation in UTH. The UTH response was found to be stronger in June than in December. A strong negative correlation is found between UTH and OLR perturbations, with OLR measured using the Geostationary Earth Radiation Budget (GERB) instrument. This pattern is stronger in December than June.
