description: We study the dynamical evolution of supermassive black holes, in the late stage of galaxy mergers, from kpc to pc scales. In particular, we capture the formation of the binary, a necessary step before the final coalescence, and trace back the main processes causing the decay of the orbit. We use hydrodynamical simulations of galaxy mergers with different resolutions, from $20\,\rm pc$ down to $1\,\rm pc$, in order to study the effects of the resolution on our results, remove numerical effects, and assess that resolving the influence radius of the orbiting black hole is a minimum condition to fully capture the formation of the binary. Our simulations include the relevant physical processes, namely star formation, supernova feedback, accretion onto the black holes and the ensuing feedback. We find that, in these mergers, dynamical friction from the smooth stellar component of the nucleus is the main process that drives black holes from kpc to pc scales. Gas does not play a crucial role and even clumps do not induce scattering or perturb the orbits. We compare the time needed for the formation of the binary to analytical predictions and suggest how to apply such analytical formalism to obtain estimates of binary formation times in lower resolution simulations.

description: We demonstrate that in a coupled two-qubit system any single-qubit gate can be decomposed into two conditional two-qubit gates and that any conditional two-qubit gate can be implemented by a manipulation analogous to that used for a controlled two-qubit gate. Based on this we present a unified approach to implement universal single-qubit and two-qubit gates in a coupled two-qubit system with fixed always-on coupling. This approach requires neither supplementary circuit or additional physical qubits to control the coupling nor extra hardware to adjust the energy level structure. The feasibility of this approach is demonstrated by numerical simulation of single-qubit gates and creation of two-qubit Bell states in rf-driven inductively coupled two SQUID flux qubits with realistic device parameters and constant always-on coupling.

description: One of the ultimate missions of lattice QCD is to simulate atomic nuclei from the first principle of the strong interaction. This is an extremely hard task for the current computational technology, but might be reachable in coming quantum computing era. In this paper, we discuss the computational complexities of classical and quantum simulations of lattice QCD. It is shown that the quantum simulation scales better as a function of a nucleon number and thus will outperform for large nuclei.
Analysis of blow-ups for the double obstacle problem in dimension two

description: In this article we study a normalised double obstacle problem with polynomial obstacles $ p^1\leq p^2$ under the assumption that $ p^1(x)=p^2(x)$ iff $ x=0$. In dimension two we give a complete characterisation of blow-up solutions depending on the coefficients of the polynomials $p^1, p^2$. In particular, we see that there exists a new type of blow-ups, that we call double-cone solutions since the coincidence sets $\{u=p^1\}$ and $\{u=p^2\}$ are cones with a common vertex. We prove the uniqueness of blow-up limits, and analyse the regularity of the free boundary in dimension two. In particular we show that if the solution to the double obstacle problem has a double-cone blow-up limit at the origin, then locally the free boundary consists of four $C^{1,γ}$-curves, meeting at the origin. In the end we give an example of a three-dimensional double-cone solution.

The analysis is based on data containing 347 million BBbar events recorded with the BaBar detector at the PEP-II asymmetric B factory. We measure the branching fractions BR(B+ -> rho+ gamma) = (1.10 +0.37/-0.33 +/- 0.09) x 10-6 and BR(B0 -> rho0 gamma) = (0.79 +0.22/-0.20 +/- 0.06) x 10-6, and set a 90% C.L. upper limit BR(B0 -> omega gamma) < 0.78 x 10-6. We also measure the isospin-averaged branching fraction BR(B->rho/omega gamma) = (1.25 +0.25/-0.24 +/- 0.09) x 10-6, from which we determine |Vtd/Vts| = 0.200 +0.021/-0.020 +/- 0.015, where the first uncertainty is experimental and the second is theoretical.

description: Thermo-osmotic flows, generated at liquid-solid interfaces by thermal gradients, can be used to produce electric currents from waste heat on charged surfaces. The two key parameters controlling the thermo-osmotic current are the surface charge and the interfacial enthalpy excess due to liquid-solid interactions. While it has been shown that the contribution from water to the enthalpy excess can be crucial, how this contribution is affected by surface charge remained to be understood. Here, we start by discussing how thermo-osmotic flows and induced electric currents are related to the interfacial enthalpy excess. We then use molecular dynamics simulations to investigate the impact of surface charge on the interfacial enthalpy excess, for different distributions of the surface charge, and two different wetting conditions. We observe that surface charge has a strong impact on enthalpy excess, and that the dependence of enthalpy excess on surface charge depends largely on its distribution. In contrast, wetting has a very small impact on the charge-enthalpy coupling. We rationalize the results with simple analytical models, and explore their consequences for thermo-osmotic phenomena. Overall, this work provides guidelines to search for systems providing optimal waste heat recovery performance.

The Effect of Annealing on the Reversal of Amorphization in Plutonium Tetrafluoride

description: This dissertation is focused on the radiolysis of plutonium tetrafluoride under long-term storage conditions. Amorphous plutonium tetrafluoride samples were subjected to thermogravimetric/differential thermal analyses, X-ray diffraction analyses, and muffle furnace annealing experiments in argon gas to investigate the totality of this radiolysis, and the effect that thermal annealing has on its reordering. There are three main areas of focus presented in this work that were used to investigate these phenomena. First, thermogravimetric/differential thermal analyses and X-ray diffraction analyses were used to uncover the possible mechanisms responsible for the amorphization in plutonium tetrafluoride through pre-annealing and post-annealing analyses on milligram samples. Second, gram samples of the plutonium tetrafluoride were annealed within flowing argon gas for short time durations. These samples were analyzed with X-ray diffraction to determine the rapidity of recrystallization in plutonium tetrafluoride. Third, gram samples of the plutonium tetrafluoride were annealed within flowing argon gas for long time durations. These samples were analyzed with X-ray diffraction to determine the effect of time at temperature on the recrystallization in plutonium tetrafluoride. The results of these three investigations are that plutonium tetrafluoride that has been stored near 50 years is amorphous. Its amorphization appears to be a result of self-induced alpha radiolysis from the decay of the plutonium isotopes. The alpha particle and the recoil nucleus of this decay look to be the primary driver of this radiolysis through Frenkel type defects and F-center formation. Radiolysis in plutonium tetrafluoride does not follow the crystal lattice parameter expansion as seen in plutonium dioxide. The crystallite size in amorphous plutonium tetrafluoride has been shown to increase under annealing conditions, and this recrystallization begins near 400°C under short and long time scales (minutes to hours) in argon gas.

description: In the last decades there have been an increasing interest in improving the accuracy of spacecraft navigation and trajectory data. In the course of this plan some anomalies have been found that cannot, in principle, be explained in the context of the most accurate orbital models including all known effects from classical dynamics and general relativity. Of particular interest for its puzzling nature, and the lack of any accepted explanation for the moment, is the flyby anomaly discovered in some spacecraft flybys of the Earth over the course of twenty years. This anomaly manifest itself as the impossibility of matching the pre and post-encounter Doppler tracking and ranging data within a single orbit but, on the contrary, a difference of a few mm$/$s in the asymptotic velocities is required to perform the fitting. Nevertheless, no dedicated missions have been carried out to elucidate the origin of this phenomenon with the objective either of revising our understanding of gravity or to improve the accuracy of spacecraft Doppler tracking by revealing a conventional origin. With the occasion of the Juno mission arrival at Jupiter and the close flybys of this planet, that are currently been performed, we have developed an orbital model suited to the time window close to the perijove. This model shows that an anomalous acceleration of a few mm$/$s$^2$ is also present in this case. The chance for overlooked conventional or possible unconventional explanations is discussed.

description: Terahertz nonlinear optics is a viable method to interrogate collective phenomena in quantum materials spanning ferroelectrics, charge-density waves, and superconductivity. In superconductors this includes the Higgs amplitude and Josephson phase modes. We have investigated the nonlinear c-axis response of optimally doped La$_{1.85}$Sr$_{0.15}$CuO$_4$ using high-field THz time domain spectroscopy (THz-TDS) at field strengths up to $\sim$80 kV/cm. With increasing field, we observe a distinct red-shift of the Josephson plasma edge and enhanced reflectivity (above the plasma edge) arising from third harmonic generation. The non-monotonic temperature dependent response is consistent with nonlinear drive of the Josephson Plasma Mode (JPM) as verified with comparison to theoretical expectations. Our results add to the understanding that, using THz light, the JPM (in addition to the Higgs mode) provides a route to interrogate and control superconducting properties.

We demonstrate operation of a controlled-Z gate in both continuous-wave and pulsed regimes of operation, fully characterising it in each case using quantum process tomography. We also demonstrate a fully-resolving, nondeterministic optical Bell-state analyser based on this controlled-Z gate. This new architecture is ideally suited to guided optics implementations of optical gates.

The effect of atomistic interactions on RNA conformational distributions, folding and ligand binding via molecular dynamics simulations and docking
Creators: name: Sadat Hayatshahi, Sayyed Hamed
Publisher: name: University of Utah
Year: 2019

description: Advances in molecular dynamics (MD) simulation methodologies have enabled researchers to explore the conformational spaces of biological macromolecules more efficiently and quickly. Specifically, the development of enhanced sampling techniques has provided researchers with well-converged conformational ensembles of small macromolecules. It has been shown that converged simulations of small ribonucleic acids (RNA) such as tetranucleotides result in the population of experimentally unknown conformations, indicating RNA force field artifacts. However, although being imperfect, the current RNA force fields have also been useful in characterizing the varied interactions of ions and ligands with RNA. In this thesis, we analyze conformational ensembles of dinucleotide monophosphates generated with different force fields and water models with the aim of pinpointing force field problems. We also utilize the current force fields to demonstrate the preferential potassium binding to a buried ion-binding site in a ribosomal RNA molecule known as GTPase Associating Center (GAC) and also to elucidate an ion-dependent step in its unfolding pathway. We further show magnesium-independency of binding of a crystallographic 2-benzimidazole ligand to the Internal Ribosome Entry Site (IRES) of Hepatitis C virus (HCV), using MD simulations and docking. Our strategy is to assess simulation results with existing experimental data, and then also use simulation results to increase insight into RNA interactions and folding. These methods allow us to identify deficiencies of some current RNA force fields.
The Effects of Commonly Used Antibiotic Medications on the Efficacy of Tyrosine Kinase Inhibitors in Philadelphia Chromosome Positive Leukemia

description: The main purpose of this thesis project is to develop and validate a high-throughput protocol to test drug-drug interactions. As a model, tyrosine kinase inhibitors were tested with commonly used antibiotics in Philadelphia chromosome positive leukemia patients. Tyrosine kinase inhibitors (TKI's), such as imatinib mesylate and dasatinib, are currently the frontline therapeutic agents for patients with leukemia characterized with the presence of the Philadelphia chromosome (Ph+), generated through a translocation event between chromosomes 9 and 22 (t[9,22][q34;q11]). However, interactions between TKI's and medications commonly taken by patients with leukemia, including antibiotics, have not been significantly studied. In this thesis, a protocol was established using innovative, high-throughput technology to determine imatinib and dasatinib maximal inhibitory concentrations and possible interactions with drugs that are often administered concomitantly with TKI therapy, antibiotics in particular. K562 cells were cultured in the presence of TKI's and cell proliferation was measured. Inhibitory concentrations of the TKI's were determined. Imatinib at concentrations IC10, IC50, and IC90 were then co-incubated with co-medications at concentrations reflecting therapeutic exposure. Co-medications were gentamicin, ceftazidime, sulfamethoxazole, trimethoprim, and a combination of sulfamethoxazole and trimethoprim at a 1:23 ratio, respectively, to emulate the constituents of the antibiotic commonly known as Bactrim. The results determined that sulfamethoxazole and trimethoprim have no significant effect on K562 cell proliferation or the ability of imatinib to reduce K562 cell proliferation. Gentamicin and ceftazidime displayed no difference from control perturbation on imatinib efficacy. However, gentamicin and ceftazidime were found to have an effect on K562 proliferation without the addition of a TKI. Therefore, further investigation is necessary to understand the mechanism behind gentamicin and ceftazidime reducing K562 cell proliferation. This assay can also be used to assess for potential in vitro TKI-drug interactions using robust, high-throughput screening techniques.

description: Red Blood Cells flowing in a microchannel undergo dispersion in the flow direction due to the non-uniform velocity profile while transverse migration due to cell-wall interactions tends to focus them along the center line. This results in a dispersion of RBC transit times through a capillary that is directly related to their transverse migration properties. By analogy with the Taylor-Aris problem, we present an experimental method to characterise this phenomenon by injecting pulses of red blood cells and measuring the evolution of their length along the channel, and varying mechanical parameters such as RBC deformability and fluid viscosity. A direct comparison of experimental results with a model that incorporates longitudinal advection and transverse migration shows that this principle provides through a simple dispersion measurement an evaluation of migration characteristics that are directly connected to cell mechanical properties.

description: The $\sim 3σ$ discrepancy between the predicted and observed reactor anti-neutrino flux, known as the reactor anti-neutrino anomaly, continues to intrigue. The recent discovery of an unexpected bump in the reactor anti-neutrino spectrum, as well as indications that the flux deficit is different for different fission isotopes seems to disfavour the explanation of the anomaly in terms of sterile neutrino oscillations. We critically review this conclusion in view of all available data on electron (anti)neutrino disappearance. We find that the sterile neutrino hypothesis cannot be rejected based on global data and is only mildly disfavored compared to an individual rescaling of neutrino fluxes from different fission isotopes. The main reason for this is the presence of spectral features in recent data from the NEOS and DANSS experiments. If state-of-the-art predictions for reactor fluxes are taken at face value, sterile neutrino oscillations allow a consistent description of global data with a significance close to $3σ$ relative to the no-oscillation case. Even if reactor fluxes and spectra are left free in the fit, a $2σ$ hint in favour of sterile neutrinos remains, with allowed parameter regions consistent with an explanation of the anomaly in terms of oscillations.

It is shown that $Z_{2n}$ orbifold models have massless conjugate pairs, $R$ and $\overline R$, in certain twisted sectors as well as one of untwisted subsectors. Using these twisted sectors, $Z_{2n}$ orbifold models are classified into two types. Conjugate pairs, $R$ and $\overline R$, lead to $D$-flatness as $\langle R \rangle = \langle \overline R \rangle \neq 0$. We investigate generic superpotentials derived from orbifold models so as to show that this direction is indeed a flat direction.

description: This paper presents the TransBoat, a novel omnidirectional unmanned surface vehicle (USV) with a magnetbased docking system for overwater construction with wave disturbances. This is the first such USV that can build overwater structures by transporting modules. The TransBoat incorporates two features designed to reject wave disturbances. First, the TransBoat's expandable body structure can actively transform from a mono-hull into a multi-hull for stabilization in turbulent environments by extending its four outrigger hulls. Second, a real-time nonlinear model predictive control (NMPC) scheme is proposed for all shapes of the TransBoat to enhance its maneuverability and resist disturbance to its movement, based on a nonlinear dynamic model. An experimental approach is proposed to identify the parameters of the dynamic model, and a subsequent trajectory tracking test validates the dynamics, NMPC controller and system mobility. Further, docking experiments identify improved performance in the expanded form of the TransBoat compared with the contracted form, including an increased success rate (of ~ 10%) and reduced docking time (of ~ 40 s on average). Finally, a bridge construction test verifies our system design and the NMPC control method.

Effects of Relative Permeability and Capillary Pressure on Numerical Simulations of Multiphase Flow in Geologic Carbon Storage Formations

description: A critical aspect in the risk assessment of geologic carbon storage, a carbon-emissions reduction method under extensive review and testing, is effective multiphase CO2 flow and transport simulation. Relative permeability and capillary pressure are flow parameters particularly critical for accurate forecasting of multiphase behavior of CO2 in the subsurface. The relative permeability relationship assumed and especially the residual saturation of the gas phase greatly impacts predicted CO2 trapping mechanisms and long-term plume migration behavior. The capillary pressure relationship assumed will impact the long-term CO2 plume movement in the reservoir and the sealing behavior of the cap rock. A primary goal of this study is to evaluate the impact the selection of relative permeability and capillary pressure relationships has on the efficacy of regional-scale CO2 sequestration models. To accomplish this, we selected the San Rafael Swell area of East-central Utah as a case study to evaluate the impact of two-phase relative permeability formulations on CO2 plume movement and behavior. We evaluated five different relative permeability relationships to quantify their relative impacts on forecasted flow results of the model, with all other parameters maintained uniform and constant. A second study site, the Farnsworth Unit (FWU) in North Texas, was used to evaluate the impact of relative permeability and capillary pressure relationships in a three-phase environment (gas, oil, water). We applied a novel approach to assigning relative permeability and capillary pressure relationships in the FWU numerical model. Ongoing work by the SWP has identified distinct regions of porosity and permeability coloration that are believed to exhibit similar flow characteristics called hydrostratigraphic units. We assign and calibrate relative permeability and capillary pressure by hydrostratigraphic units (heterogeneous parameter assignment). Petrophysical and mercury intrusion capillary pressure measurements for each of the hydrostratigraphic units were used to calibrate and parameterize relative permeability relationship and capillary pressure relationships. Results of forward simulations with the newly-calibrated models were compared to models that assigned relative permeability and capillary pressure by geologic formation or lithology alone (homogenous parameter assignment).

description: We present pulse-phase X-ray spectroscopy of the high-mass X-ray pulsar SMC X-1 from five different epochs, using Chandra X-ray Observatory ACIS-S and XMM-Newton EPIC-pn data. The X-ray spectrum consistently shows two distinct components, a hard power law and a soft blackbody with kT_BB ~ 0.18 keV. For all five epochs the hard component shows a simple double-peaked pulse shape, and also a variation in the power law slope, which becomes harder at maximum flux and softer at minimum flux. For the soft component, the pulse profile changes between epochs, in both shape and phase relative to the power law pulses. The soft component is likely produced by reprocessing of the hard X-ray pulsar beam by the inner accretion disk. We use a model of a twisted inner disk, illuminated by the rotating X-ray pulsar beam, to simulate pulsations in the soft component due to this reprocessing. We find that for some disk and beam geometries, precession of an illuminated accretion disk can roughly reproduce the observed long-term changes in the soft pulse profiles.

description: The radio spectral index is a powerful probe for classifying cosmic radio sources and understanding the origin of the radio emission. Combining data at 147 MHz and 1.4 GHz from the TIFR GMRT Sky Survey (TGSS) and the NRAO VLA Sky Survey (NVSS), we produced a large-area radio spectral index map of ~80 per cent of the sky (Dec > -40 deg), as well as a radio spectral index catalogue containing 1,396,515 sources, of which 503,647 are not upper or lower limits. Almost every TGSS source has a detected counterpart, while this is true only for 36 per cent of NVSS sources. We released both the map and the catalogue to the astronomical community. The catalogue is analysed to discover systematic behaviours in the cosmic radio population. We find a differential spectral behaviour between faint and bright sources as well as between compact and extended sources. These trends are explained in terms of radio galaxy evolution. We also confirm earlier reports of an excess of steep-spectrum sources along the galactic plane. This corresponds to 86 compact and steep-spectrum source in excess compared to expectations. The properties of this excess are consistent with normal non-recycled pulsars, which may have been missed by pulsation searches due to larger than average scattering along the line of sight.

description: Einstein's theory of General Relativity implies that energy, i.e. matter, curves space-time and thus deforms lightlike geodesics, giving rise to gravitational lensing. This phenomenon is well understood in the case of the Schwarzschild metric, and has been accurately described in the past; however, lensing in the Kerr space-time has received less attention in the literature despite potential practical observational applications. In particular, lensing in such space is not expressible as the gradient of a scalar potential and as such is a source of curl-like signatures and an asymmetric shear pattern. In this paper, we develop a differentiable lensing map in the Kerr metric, reworking and extending previous approaches. By using standard tools of weak gravitational lensing, we isolate and quantify the distortion that is uniquely induced by the presence of angular momentum in the metric. We apply this framework to the distortion induced by a Kerr-like foreground object on a distribution of background of sources. We verify that the new unique lensing signature is orders of magnitude below current observational bounds for a range of lens configurations.

description: From a new perspective, we discuss the thermodynamic entropy of $n+2$-dimensional Reissner-Nordström-de Sitter(RNdS) black hole and analyze the phase transition of the effective thermodynamic system. Considering the correlations between the black hole event horizon and the cosmological horizon, we conjecture that the total entropy of the RNdS black hole should contain an extra term besides the sum of the entropies of the two horizons. In the lukewarm case, the effective temperature of the RNdS black hole is the same as that of the black hole horizon and the cosmological horizon. Under this condition, we obtain the extra contribution to the total entropy. With the corrected entropy, we derive other effective thermodynamic quantities and analyze the phase transition of the RNdS black hole in analogy to the usual thermodynamic system.

The Effects of a Bullying Prevention Program on Bullying Expression and Overall School Climate
Creators: name: Allen, Dania Lisette
Publisher: name: University of Utah
Year: 2019

description: The purpose of this study was to determine whether a bullying prevention program would decrease student reports of victimization, perpetrating of bullying acts, and witnessing bullying behavior, as well as increase student-reported feelings of safety. Teacher reports of school climate and witnessing bullying were also assessed. Participants in this study were third-, fourth-, and fifth-grade students and their classroom teachers, from two suburban K-8 schools in the southwestern part of the United States. Bullying Prevention - Positive Behavior Supports (BP-PBS) was used at the experimental school as the intervention. The control group received no intervention. Students completed a researcher-created questionnaire pre- and postintervention, which assessed student-reported victimization, witnessing of bullying behavior, self-reported bullying behavior, and feelings of overall safety. Teachers at both schools completed the School Climate Inventory - Revised (SCI-R), as well as a teacher-version of the bullying questionnaire. An analysis of covariance (ANCOVA) was conducted to statistically adjust for baseline differences in three variables. A two-way ANOVA was used for the remaining variable (perpetrator) to determine if significant changes occurred following the intervention. Results from the ANCOVA indicate significant effect at postintervention for the victim variable (F (1, 434) = 4.450, p = .035) and the witness variable (F (1, 434) = 15.063, p = .000). ANCOVA results were not significant for the safety variable (F (1, 434) = .359, p = .549). Two-way ANOVA results were not significant for iv the perpetrator variable (F (1, 434) = 2.701, p = .101). ANCOVA results were not significant for the teacher bullying questionnaire for school (F (1,20) = .846, p = .377) or the SCI-R for school (F (1, 20) = .054, p = .830) or grade (F (2,20) = .932, p = .423). ANCOVA results were significant for the teacher bullying questionnaire for grade (F (2, 20) = .4663, p = .034). Analysis of the ODRs indicate no difference in reports of bullying from the 2015-2016 to 2016-2017 school years.

description: We construct a sequence of explicit blow-ups and blow-downs on irreducible compact Hermitian symmetric spaces $X$ which transforms it into a projective space of the same dimension. Moreover this resolves a birational map given by Landsberg and Manivel. Centers of the blow-ups for $X$ are constructed by loci of chains of minimal rational curves and centers of the blow-ups for the projective space are constructed from the variety of minimal rational tangents of $X$ and its higher secant varieties.

The Geometry of $N=2$ Strings with Torsion

Year: 1996
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: $N=2$ string theories are formulated in space-times with 2 space and 2 time dimensions. If the world-sheet matter system consists of 2 chiral superfields, the space-time is Kahler and the dynamics are those of anti-self-dual gravity. If instead one chiral superfield and one twisted chiral superfield are used, the space-time is a hermitian manifold with torsion and a dilaton. The string spectrum consists of a scalar, which is a potential $K$ determining the metric, torsion and dilaton. The dynamics imply that the curvature with torsion is anti-self-dual, and an action is found for the potential $K$. It is argued that any $N=2$ sigma-model with twisted chiral multiplets in any dimension can be deformed to a conformally invariant theory if the lowest order contribution to the conformal anomaly vanishes. If there are isometries, more general geometries are possible in which the dilaton is the Killing potential for a holomorphic Killing vector.
description: 10 pages, phyzzx, no figures. The discussion of conformal invariance is improved, and the class of geometries considered is generalised to include general dilaton backgrounds, in which the dilaton is the Killing potential for a holomorphic isometry

description: In this paper we discuss the X-ray point source population of NGC 4472, an elliptical galaxy in the Virgo cluster. We used recent deep Chandra data combined with archival Chandra data to obtain a 380 ks exposure time. We find 238 X-ray point sources within 3.7' of the galaxy centre, with a completeness flux, F(X,0.5-2 keV)= 6.3x$10^{-16}$ $erg s^{-1} cm^{-2}$. Most of these sources are expected to be low mass X-ray binaries. We finding that, using data from a single galaxy which is both complete and has a large number of objects (~ 100) below 10$^{38}$ $erg s^{-1}$, the X-ray luminosity function is well fit with a single power law model. By cross matching our X-ray data with both space based and ground based optical data for NGC 4472, we find that 80 of the 238 sources are in globular clusters. We compare the red and blue globular cluster subpopulations and find red clusters are nearly six times more likely to host an X-ray source than blue clusters. We show that there is evidence that these two subpopulations have significantly different X-ray luminosity distributions. Source catalogues for all X-ray point sources, as well as any corresponding optical data for globular cluster sources, are also presented here.
