description: We study the orbital evolution of eccentric binary neutron stars. The orbit is described as a Quasi-Keplarian orbit with perturbations due to tidal couplings. We find that the tidal interaction between stars contributes to orbital precession, in addition to the Post-Newtonian procession. The coupling between the angular and radial motion of the binary also excites a series of harmonics in the stars' oscillation. In the small eccentricity limit, this coupling mainly gives rise to an additional orbital resonance, with the orbital frequency being one third of the f-mode frequency. For a binary with initial eccentricity $\sim 0.2$ at $50$Hz orbital frequency, the presence of this tidal resonance introduces $\sim 0.5$ phase shift in the gravitational waveform till merger, subject to uncertainties in neutron star equation of state and the distribution of binary component masses. Such phase shift in the late-inspiral stage is likely detectable with third-generation gravitational-wave detectors.

description: We use a semi-analytic model of halo formation to study the dynamical history of giant field galaxies like the Milky Way. We find that in a concordance LCDM cosmology, most isolated disk galaxies have remained undisturbed for 8-10 Gyr, such that the age of the Milky Way's thin disk is unremarkable. Many systems also have older disk components which have been thickened by minor mergers, consistent with recent observations of nearby field galaxies. We do have a considerable problem, however, reproducing the morphological mix of nearby galaxies. In our fiducial model, most systems have disk-to-bulge mass ratios of order 1, and look like S0s rather than spirals. This result depends mainly on merger statistics, and is unchanged for most reasonable choices of our model parameters. We discuss two possible solutions to this morphology problem in LCDM.

Observational constraints on growth of massive black holes

Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the observational constraints on the growth of massive black holes (BHs) in galactic nuclei. We use the velocity dispersions of early-type galaxies obtained by the SDSS and the relation between BH mass and velocity dispersion to estimate the local BH mass density to be 2.5x10^5 Msun/Mpc^3. We also use the QSO luminosity function from the 2dF Redshift Survey to estimate the BH mass density accreted during optically bright QSO phases. The local BH mass density is consistent with the density accreted during optically bright QSO phases if QSOs have an efficiency 0.1. By studying the continuity equation for the BH mass distribution, including the effect of BH mergers, we find relations between the local BH mass function and the QSO luminosity function. If the BH mass is assumed to be conserved during BH mergers, comparison of the predicted relations with the observations suggests that luminous QSOs (L_{bol}>10^{46} erg/s) have a high efficiency (e.g. 0.2), and the growth of high-mass BHs (>10^8 Msun) comes mainly from accretion during optically bright QSO phases, or that luminous QSOs have a super-Eddington luminosity. If luminous QSOs are not accreting with super-Eddington luminosities and the growth of low-mass BHs also occurs mainly during optically bright QSO phases, less luminous QSOs must accrete with a low efficiency <0.1; alternatively, they may accrete with high efficiency, but a significant fraction should be obscured. We estimate that the mean lifetime of luminous QSOs is (3-13)x10^7 yr, which is comparable to the Salpeter time. We also investigate the case in which total BH mass decreases during BH mergers due to gravitational radiation, and the observations again suggest that BHs in most luminous QSOs are Kerr BHs accreting with an efficiency >0.1.

description: The current state of the chemical functionalization of three types of single sheet 2D materials, namely, graphene, molybdenum disulfide (MoS2), and black phosphorus (BP) is summarized. Such 2D sheet polymers represent currently an emerging field at the interface of synthetic chemistry, physics, and materials science. Both covalent and non-covalent functionalization of sheet architectures allows for a systematic modification of their properties, i.e. an improvement of solubility and processability, the prevention of re-aggregation or a band gap tuning. Next to successful functionalization concepts also fundamental challenges are addressed. These include the insolubility and polydispersity of most 2D sheet polymers, the development of suitable characterization tools, the identification of effective binding strategies, the chemical activation of the usually rather unreactive basal planes for covalent addend binding, and the regioselectivity of plane addition reactions. Although a number of these questions remain elusive in this review, the first promising concepts to overcome such hurdles have been listed.
Three-dimensional MHD simulations of Radiatively cooling, Pulsed Jets

description: (Abridged) We here investigate, by means of fully 3-D Smoothed Particle Magnetohydrodynamic numerical simulations, the effects of magnetic fields on overdense, radiatively cooling, pulsed jets, using different initial magnetic field topologies and strengths ($B \simeq 260 μ$G-0). The relative differences that have been previously detected in 2-D simulations involving distinct magnetic field configurations are diminished in the 3-D flows. While the presence of toroidal magnetic components can modify the morphology close to the jet head inhibiting its fragmentation in the early jet evolution, as previously reported in the literature, the impact of the pulsed-induced internal knots causes the appearance of a complex morphology at the jet head (as required by the observations of H-H jets) even in the MHD jet models with toroidal components. The detailed structure and emission properties of the internal working surfaces can be also significantly altered by the presence of magnetic fields. The increase of the magnetic field strength improves the jet collimation, and amplifies the density (by factors up to 1.4, and 4) and the Hα$ intensity (by factors up to 4, and 5) behind the knots of jets with helical field and $β\simeq 1-0.1$ (respectively), relative to a non magnetic jet. As a consequence, the corresponding $I_{[SII]}}/I_{H}α}$ ratio (which is frequently used to determine the excitation level of HH objects) can be decreased in the MHD models with toroidal components relative to non-magnetic calculations. We also find that the helical mode of the K-H instability can be triggered in MHD models with helical magnetic fields, causing some jet wiggling. No evidence for the formation of the nose cones is found in the 3-D flows, nor even in the $β\simeq 0.1$ case.

We contrast the systematic errors that afflict such a system with those that affect correlation polarimeters; the Planck design has some important advantages when measuring very weak signals such as the CMB. We also review systematic effects arising from the choice of scan strategy for all-sky mapping missions like Planck.[For the Planck-LFI consortium].

description: We investigate the Lagrangian statistics of three-dimensional rotating turbulent flows through direct numerical simulations. We find that the emergence of coherent vortical structures because of the Coriolis force leads to a suppression of the "flight-crash" events reported by Xu, et al. [Proc. Natl. Acad. Sci. (U.S.A) 111, 7558 (2014)]. We perform systematic studies to trace the origins of this suppression in the emergent geometry of the flow and show why such a Lagrangian measure of irreversibility may fail in the presence of rotation.

description: Infrared Space Observatory 3 - 25 $μ$m spectra of the R Coronae Borealis stars V854 Cen, R CrB, and RY Sgr are presented and discussed. Sharp emission features coincident in wavelengths with the well known Unidentified Emission Features are present in the spectrum of V854 Cen but not of R CrB or RY Sgr. Since V854 Cen is not particularly H-poor and has a 1000 times more H than the other stars, the emission features are probably from a carrier containing hydrogen. There is a correspondence between the features and emission from laboratory samples of hydrogenated amorphous carbon. A search for C$_{60}$ in emission or absorption proved negative. Amorphous carbon particles account for the broad emission features seen between 6 - 14 $μ$m in the spectrum of each star.

Subjects: subject: financial stress

description: Financial stress creates pressure on individuals and families and can contribute to various short- and long-term issues. It not only affects the lives of the individuals, but also has a profound influence on countries’ politics and development. This thesis expands the explorations and study of this particularly sensitive and complex issue, focusing on the effects of financial stress on psychosocial processes in Australia. With the liberalisation and deregulation of financial markets, wide array of financial products and services become more available, and consumers are presented with more challenges and opportunities alike. The continuous progress of financial liberalisation challenges the whole society, requiring people to be well‐equipped with financial knowledge and financial skills to make sound financial decisions. A low level of financial literacy is more likely to lead to mismanaged savings and to affect retirement wealth accumulation. Inadequate financial management can result in financial hardship, with elevated levels of distress from greater exposure to chronic and acute stressors, such as monthly bills payment difficulties, family and relationship problems, and poor neighbourhood relations. This thesis uses cross-sectional and longitudinal panel data obtained from HILDA, the Household, Income and Labour Dynamics in Australia Survey, to generate a model to analyse the impact of financial stress on psychosocial processes in Australia. For the purpose of this analysis, indexes for financial stress, financial literacy, financial self-efficacy and social cohesion were developed to study these effects on Australian households. [...]
Making Birth-Death Processes from Backward Fokker-Planck Equations for Computing Expectations in Langevin Systems

description: A method to direct evaluation of expectations for Langevin systems (stochastic differential equations) is proposed. The method is based on a birth-death process which is derived using combinations of dummy variables and It{ô} formula. As a pedagogical example, a double-well system and expectations for sigmoid-type functions are used. It is shown that the proposed method has some merits from computational point of view; only one time-integration for the birth-death process gives expectations for various initial conditions in the original Langevin systems. Furthermore, the same time-integration result is available for computing various center positions of the sigmoid-type functions.

description: Educational attainment and work outcomes for young people in state care are often poor, leaving them ill-prepared to live independently as adults (Biehal, Clayden, Stein, & Wade, 1994; Courtney, Dworsky, Lee, & Raap, 2010; Elze, Auslander, Stiffman, & McMillen, 2005; Jackson & Ajayi, 2007; Wade & Dixon, 2006). Most encounter obstacles to finding and sustaining employment in the early years after care (Cheung & Heath, 1994; Dworsky, 2005; Jackson & Cameron, 2012; Mendes, 2009) and have compromised employment pathways such as under-employment, low rates of pay and slow employment progress (Dixon, 2006; Goerge et al., 2002; Hook & Courtney, 2011). This thesis is concerned with the school-to-work transition for young people in care and how they develop ideas and plans about future work options. This process is also known as career development. Career development is a life-long process related to choosing an occupation and lifestyle (Brown & Brooks, 1990; Hartung, Porfeli, & Vondracek, 2005). It involves self-knowledge, knowledge of the world of work and true reasoning (Parsons, 1909; Patton & McMahon, 1999), and may be influenced by a range of individual and environmental factors (Lent, Brown, & Hackett, 1996). There is a general view of the centrality of career engagement to adult self-sufficiency and functioning (Astin, 1984), but little is known about the career development process for young people in care.

description: Young adolescents today are growing up in an environment rich in digital technology. They are highly connected with their technology always on and always on them. In this digital culture there are consistent concerns regarding the impact of this new way of being, and adult-generated concerns include perceived diminished childhood, bullying and fear which dominate much of the widely held understanding of the digital culture which these young people inhabit. In this culture of fear and in the context of schools, adult-generated strategies for enhancing the experience of young people engaging with social networking is generally the norm and student voice is repressed. In contrast, this study set out to explore the experience of young people with respect to their engagement with social networking, through the privileging of student voice rather than assuming that adult knowledge be applied. Specifically, students aged from approximately 12-16 years, in the middle years of schooling (Years 7-9), are the subject of this study as they constitute the years where rapid growth and development, identity formation and establishing practices associated with social networking occur.

description: Symplectic integrators are a foundation to the study of dynamical $N$-body phenomena, at scales ranging from from planetary to cosmological. These integrators preserve the Poincaré invariants of Hamiltonian dynamics. The $N$-body Hamiltonian has another, perhaps overlooked, symmetry: it is smooth, or, in other words, it has infinite differentiability class order (DCO) for particle separations greater than $0$. Popular symplectic integrators, such as hybrid methods or block adaptive stepping methods do not come from smooth Hamiltonians and it is perhaps unclear whether they should. We investigate the importance of this symmetry by considering hybrid integrators, whose DCO can be tuned easily. Hybrid methods are smooth, except at a finite number of phase space points. We study chaotic planetary orbits in a test considered by Wisdom. We find that increasing smoothness, at negligible extra computational cost in particular tests, improves the Jacobi constant error of the orbits by about $5$ orders of magnitude in long-term simulations. The results from this work suggest that smoothness of the $N$-body Hamiltonian is a property worth preserving in simulations.

description: In a 52 ks-long Chandra ACIS-S observation of the nearby starburst galaxy NGC 3628, obtained to study the starburst-driven outflow from this galaxy, we have detected a very luminous (L_X = 1.1e40 erg/s in the 0.3-8.0 keV energy band) point source located at least 20 arcsec (~970 pc) from the nucleus of the galaxy. No radio, optical or near-IR counterpart to this source has been found. This is most probably the reappearance of the strongly-variable X-ray-luminous source discovered by Dahlem et al (1995), which faded by a factor >27 between December 1991 and March 1994 (at which point it had faded below the detection limit in a ROSAT HRI observation). This source is clearly a member of an enigmatic class of X-ray sources that are considerably more luminous than conventional X-ray binaries but less luminous than AGN, and which are not found at the dynamical center of the host galaxy. The Chandra spectrum is best-fit by an absorbed power law model with a photon index of Gamma = 1.8+/-0.2, similar to that seen in Galactic BH binary candidates in their hard state. Bremsstrahlung models or multi-color disk models (the favored spectral model for objects in this class based on ASCA observations) can provide statistically acceptable fits only if the data at energies E > 5 keV is ignored. This is one of the first X-ray spectra of such an object that is unambiguously that of the source alone, free from the spectral contamination by X-ray emission from the rest of the galaxy that affects previous spectral studies of these objects using ASCA.

description: We generally analyze prompt high-energy emission above a few hundreds of GeV due to synchrotron self-Compton scattering in internal shocks. However, such photons cannot be detected because they may collide with cosmic infrared background photons, leading to electron/positron pair production. Inverse-Compton scattering of the resulting electron/positron pairs off cosmic microwave background photons will produce delayed MeV-GeV emission, which may be much stronger than a typical high-energy afterglow in the external shock model. We expand on the Cheng & Cheng model by deriving the emission spectrum and duration in the standard fireball shock model. A typical duration of the emission is ~ 10^3 seconds, and the time-integrated scattered photon spectrum is nu^{-(p+6)/4}, where p is the index of the electron energy distribution behind internal shocks. This is slightly harder than the synchrotron photon spectrum, nu^{-(p+2)/2}. The lower energy property of the scattered photon spectrum is dependent on the spectral energy distribution of the cosmic infrared background radiation. Therefore, future observations on such delayed MeV-GeV emission and the higher-energy spectral cutoff by the Gamma-Ray Large Area Space Telescope (GLAST) would provide a probe of the cosmic infrared background radiation.

description: Expensive black box systems arise in many engineering applications but can be difficult to optimize because their output functions may be complex, multi-modal, and difficult to understand. The task becomes even more challenging when the optimization is subject to multiple constraints and no derivative information is available. In this paper, we combine response surface modeling and filter methods in order to solve problems of this nature. In employing a filter algorithm for solving constrained optimization problems, we establish a novel probabilistic metric for guiding the filter. Overall, this hybridization of statistical modeling and nonlinear programming efficiently utilizes both global and local search in order to quickly converge to a global solution to the constrained optimization problem. To demonstrate the effectiveness of the proposed methods, we perform numerical tests on a synthetic test problem, a problem from the literature, and a real-world hydrology computer experiment optimization problem.

description: Single-shot absorption measurements have been performed using the multi-keV X-rays generated by a laser wakefield accelerator. A 200 TW laser was used to drive a laser wakefield accelerator in a mode which produced broadband electron beams with a maximum energy above 1 GeV and a broad divergence of $\approx15$ miliradians FWHM. Betatron oscillations of these electrons generated $1.2\pm0.2\times10^6$ photons/eV in the 5 keV region, with a signal-to-noise ratio of approximately 300:1. This was sufficient to allow high-resolution XANES measurements at the K-edge of a titanium sample in a single shot. We demonstrate that this source is capable of single-shot, simultaneous measurements of both the electron and ion distributions in matter heated to eV temperatures by comparison with DFT simulations. The unique combination of a high-flux, large bandwidth, few femtosecond duration X-ray pulse synchronised to a high-power laser will enable key advances in the study of ultra-fast energetic processes such as electron-ion equilibration.

description: Let f: X -> Y be a separated morphism of schemes of finite type over a finite field of characteristic p, let Lambda be an artinian local Z_p-algebra with finite residue field, let m be the maximal ideal of Lambda, and let L^\bullet be a bounded constructible complex of sheaves of finite free Lambda-modules on the étale site of Y. We show that the ratio of L-functions L(X,L^\bullet)/L(Y,f_! L^\bullet), which is a priori an element of 1+T Lambda[[T]], in fact lies in 1+ m T Lambda [T]. This implies a conjecture of Katz predicting the location of the zeroes and poles of the L-function of a p-adic étale lisse sheaf on the closed unit disk in terms of étale cohomology with compact support.

description: The Supernova/Acceleration Probe (SNAP) is a proposed space-borne observatory that will survey the sky with a wide-field optical/near-infrared (NIR) imager. The images produced by SNAP will have an unprecedented combination of depth, solid-angle, angular resolution, and temporal sampling. For 16 months each, two 7.5 square-degree fields will be observed every four days to a magnitude depth of AB=27.7 in each of the SNAP filters, spanning 3500-17000Å. Co-adding images over all epochs will give AB=30.3 per filter. In addition, a 300 square-degree field will be surveyed to AB=28 per filter, with no repeated temporal sampling. Although the survey strategy is tailored for supernova and weak gravitational lensing observations, the resulting data will support a broad range of auxiliary science programs.

Light Sheet Depth Imaging

description: As robots are developed for large-scale applications in autonomous driving, package delivery, and agriculture, there is a growing need for affordable and reliable depth sensing. Robots use active illumination sensors like scanning LIDAR and depth cameras to perceive their worlds. Scanning LIDAR is prevalent because it offers long-range, robust sensing, but it is expensive and only captures sparse point
measurements. Consumer depth cameras, on the other hand, are inexpensive and produce high-rate, dense depth measurements but fail outdoors in bright light. This thesis developed active illumination depth cameras and sensing methodologies that combine the robustness of scanning LIDAR with the speed, sampling density, and economy of consumer depth cameras. Rather than sample the entire
scene at once like consumer depth cameras or with points like LIDAR, the key approach uses sheets of projected light and imaging to rapidly sample the scene along
a single line at a time. Using this approach, four contributions have been made. The first is a contribution
to the development of a light sheet depth imaging device that applies the concept of epipolar imaging to continuous-wave time-of-flight cameras. The resulting depth camera can see up to 15 meters in bright sunlight and is robust to global illumination and motion. The next contribution developed a second generation of this camera that demonstrated sensing ranges up to 50 meters. The third contribution uses the projected sheets of light and imaging to triangulate and sense along a 3D line. By sweeping this line through the volume with galvomirrors, a programmable light curtain
is formed that detects objects along its surface at five frames per second. Finally, rapid imaging of programmable light curtains at 60 frames per second was enabled
with the custom development of a device that uses the rolling shutter of a camera to steer the imaging plane instead of a galvomirror. The speed and selectivity provided
by this device enabled applications in agile depth sensing where scenes are adaptively sampled based on detected regions of interest. The research developed in this thesis contributes methods and hardware for high resolution
depth imaging that works in challenging conditions, provides methods for computationally inexpensive agile depth sensing, and has the economics that could enable next generation and wide-scale applications in mobile robotics, agriculture, and industrial manufacturing.
Supernova Hosts for Gamma-Ray Burst Jets: Dynamical Constraints

description: I constrain a possible supernova origin for gamma-ray bursts by modeling the dynamical interaction between a relativistic jet and a stellar envelope surrounding it. The delay in observer's time introduced by the jet traversing the envelope should not be long compared to the duration of gamma-ray emission; also, the jet should not be swallowed by a spherical explosion it powers. The only stellar progenitors that comfortably satisfy these constraints, if one assumes that jets move ballistically within their host stars, are compact carbon-oxygen or helium post-Wolf-Rayet stars (type Ic or Ib supernovae); type II supernovae are ruled out. Notably, very massive stars do not appear capable of producing the observed bursts at any redshift unless the stellar envelope is stripped prior to collapse. The presence of a dense stellar wind places an upper limit on the Lorentz factor of the jet in the internal shock model; however, this constraint may be evaded if the wind is swept forward by a photon precursor. Shock breakout and cocoon blowout are considered individually; neither presents a likely source of precursors for cosmological GRBs. These envelope constraints could conceivably be circumvented if jets are laterally pressure-confined while traversing the outer stellar envelope. If so, jets responsible for observed GRBs must either have been launched from a region several hundred kilometers wide, or have mixed with envelope material as they travel. A phase of pressure confinement and mixing would imprint correlations among jets that may explain observed GRB variability-luminosity and lag-luminosity correlations.

description: For a>0,let W^a(t) be the a-neighbourhood of standard Brownian motion in R^d starting at 0 and observed until time t.It is well-known that E|W^a(t)|~kappa_a t (t->infty) for d >= 3,with kappa_a the Newtonian capacity of the ball with radius a. We prove that lim_{t->infty} 1/t^{(d-2)/d}log P(|W^a(t)|<=bt) = -I^{kappa_a}(b) in (-infty,0) for all 0infty.This is markedly different from the optimal strategy for large deviations |W^a(t)|<=f(t) with f(t)=o(t),where W^a(t) is known to fill completely a ball of volume f(t) and nothing outside,so that W^a(t) has no holes and f(t)^{-1/d}W^a(t) is localised in the limit as t->infty.We give a detailed analysis of the rate function I^{kappa_a},in particular,its behaviour near the boundary points of (0,kappa_a).It turns out that I^{kappa_a} has an infinite slope at kappa_a and,remarkably,for d>=5 is nonanalytic at some critical point in (0,kappa_a),above which it follows a pure power law.This crossover is associated with a collapse transition in the optimal strategy.We also derive the analogous moderate deviation result for d=2.In this case E|W^a(t)|~2pi t/log t (t->infty),and we prove that lim_{t->infty} 1/log t log P(|W^a(t)|<=bt/log t) =-I^{2pi}(b)in (-infty,0) for all 0
