description: We construct Green-Schwarz (GS) light-cone closed superstring theory from type IIB matrix model. A GS light-cone string action is derived from two dimensional N=8 U(n) noncommutative Yang-Mills (NCYM) by identifying noncommutative scale with string scale. Supersymmetry transformation for the light-cone gauge action is also derived from supersymmetry transformation for IIB matrix model. By identifying the physical states and interaction vertices, string theory is perturbatively reproduced.

description: We present computations of certain finite-size scaling functions and universal amplitude ratios in the large-N limit of the CP^{N-1} field theory. We pay particular attention to the uniform susceptibility, the spin stiffness and the specific heat. Field theoretic arguments have shown that the long-wavelength description of the phase transition between the Neel and valence bond solid states in square lattice S=1/2 anti-ferromagnets is expected to be the non-compact CP^1 field theory. We provide a detailed comparison between our field theoretic calculations and quantum Monte Carlo data close to the Neel -VBS transition on a S=1/2 square-lattice model with competing four-spin interactions (the JQ model).

description: Addressing the need for a new form of leadership to fight this global leadership crisis, Passion In Leadership In Organisations (PILIO) is investigated. Following a pragmatic research stance, this research is composed of three studies: a meta-aggregative literature review analysed with a Thematic Analysis (study 1), a mixed-methods Systematic Review (study 2), and a Grounded Theory Methodology analysed with descriptive statistics and thematic analysis (study 3). Study 1 examined 26 studies, study 2 reviewed a sample of 13,205 individuals across 44 global studies, and study 3 interviewed 22 Chief Executive Officers, men and women from all industries and regions of the world. The definitions of Passionate Leadership In Organisations and Passion In Leadership In Organisations are produced. A Passion In Leadership In Organisations model which identifies 4 types of leaders is revealed: Obsessive Leader, Sacrificial Leader, Managerial Leader, Passionate Leader. The theory of passion lifecycle is proposed explaining the evolutive level of passion in leadership through time, suggesting a point of optimal conditions. A dark side of PILIO continuum is revealed contrasting the dark side of passion versus the bright side of passion, and indicating ways to either lose to or to fight against passion in leadership. Dual Passion-People-Energy flow exposing the relationship between passion, energy and desire to connect with people is unpacked. The study evidences the multidimensional character of Passion In Leadership In Organisations and both the transferability and the humanistic and prosocial aspects of Passion In Leadership In Organisations are critically discussed. This study contributes to both the leadership literature and research on motivational constructs in Positive Psychology, offering practical insights beneficial to scholars, policy makers and practitioners in their quest to address the current global leadership crisis and the lack of a type of leader who can build a better world.

description: Upcoming missions such as Euclid and the Nancy Grace Roman Space Telescope (Roman) will use emission-line selected galaxies to address a variety of questions in cosmology and galaxy evolution in the $z>1$ universe. The optimal observing strategy for these programs relies upon knowing the number of galaxies that will be found and the bias of the galaxy population. Here we measure the $\rm{[O\ III]}\ λ5007$ luminosity function for a vetted sample of 1951 $m_{\rm J+JH+H} < 26$ galaxies with unambiguous redshifts between $1.90 < z < 2.35$, which were selected using HST/WFC3 G141 grism frames made available by the 3D-HST program. These systems are directly analogous to the galaxies that will be identified by the Euclid and Roman missions, which will utilize grism spectroscopy to find $\rm{[O\ III]}\ λ5007$-emitting galaxies at $0.8 \lesssim z \lesssim 2.7$ and $1.7 \lesssim z \lesssim 2.8$, respectively. We interpret our results in the context of the expected number counts for these upcoming missions. Finally, we combine our dust-corrected $\rm{[O\ III]}$ luminosities with rest-frame ultraviolet star formation rates to present a new calibration of the SFR density associated with $1.90 < z < 2.35$ $\rm{[O\ III]}$-emitting galaxies. We find that these grism-selected galaxies contain roughly half of the total star formation activity at $z\sim2$.

description: We report equations of motion for the occupation numbers of natural spin orbitals and show that adiabatic extensions of common functionals employed in ground-state reduced-density-matrix-functional theory have the shortcoming of leading always to occupation numbers which are independent of time. We illustrate the exact time-dependence of the natural spin orbitals and occupation numbers for the case of electron-ion scattering and for atoms in strong laser fields. In the latter case, we observe strong variations of the occupation numbers in time.

description: The idea of symbolic controllers tries to bridge the gap between the top-down manual design of the controller architecture, as advocated in Brooks' subsumption architecture, and the bottom-up designer-free approach that is now standard within the Evolutionary Robotics community. The designer provides a set of elementary behavior, and evolution is given the goal of assembling them to solve complex tasks. Two experiments are presented, demonstrating the efficiency and showing the recursiveness of this approach. In particular, the sensitivity with respect to the proposed elementary behaviors, and the robustness w.r.t. generalization of the resulting controllers are studied in detail.

description: We study the phase diagram of a two component Fermi system with a weak attractive interaction. Our analysis includes the leading order Hartree energy shifts and pairing correlations at finite temperature and chemical potential difference between the two fermion species. We show that in an asymmetric system, the Hartree shift to the single particle energies are important for the phase competition between normal and superfluid phase and can change the phase transition curve qualitatively. At large asymmetry we find that a novel but somewhat fragile superfluid state can be favored due to finite temperature effects. We also investigate the transition between the normal phase and an inhomogeneous superfluid phase to study how gradient instabilities evolve with temperature and asymmetry. Finally, we adopt our analysis to study the density profiles of similar asymmetric Fermi systems that are being observed in cold atom experiments.

For certain restricted classes of disordered potentials, the latter supercurrent algebra based conformal field theories can arise as non-trivial low energy fixed points. For all cases with such a fixed point, we compute the density of states exponents as a function of N.

description: The analysis of computer and communication networks gives rise to some interesting inverse problems. This paper is concerned with active network tomography where the goal is to recover information about quality-of-service (QoS) parameters at the link level from aggregate data measured on end-to-end network paths. The estimation and monitoring of QoS parameters, such as loss rates and delays, are of considerable interest to network engineers and Internet service providers. The paper provides a review of the inverse problems and recent research on inference for loss rates and delay distributions. Some new results on parametric inference for delay distributions are also developed. In addition, a real application on Internet telephony is discussed.

Stock market reaction to auditor changes by OTC firms
Creators: name: Kinnear, Valerie Ann
Publisher: name: University of British Columbia
Year: 2010

description: This thesis examines the stock market reaction to auditor change announcement by OTC firms. The general motivation stemmed from previous research on this topic that 1) failed to adequately motivate the empirical investigation and 2) found insignificant results. The theoretical justification for expecting a market reaction is based on the existence of product differentiation in the market for audit services in terms of the level of credibility an auditor can offer. It is conjectured that client firms will demand more credibility as the proportion of external ownership in the firm increases. Management's re-evaluation of their optimal residual firm value and perquisite consumption combination after a change in the ownership structure is suggested as a possible reason for an auditor change. The auditor change signals information about the manager and causes a market reaction. A sample of 44 non-Big Eight to Big Eight and 15 Big Eight to non-Big Eight auditor changes are examined. The standard event study method of abnormal residual analysis is replaced with a new method in which cross-sectional market model regressions in the announcement and a control period on the same firms are compared. Results provide strong evidence that the increase in firm value from an auditor change announcement is greater for non-Big Eight to Big Eight changes than Big Eight to non-Big Eight changes. Evidence is also found that firms changing auditors experience greater variability in returns during an announcment period than during a control period prior to the change.

Refractive Geometry for Underwater Domes

description: Underwater cameras are typically placed behind glass windows to protect them from the water. Spherical glass, a dome port, is well suited for high water pressures at great depth, allows for a large field of view, and avoids refraction if a pinhole camera is positioned exactly at the sphere's center. Adjusting a real lens perfectly to the dome center is a challenging task, both in terms of how to actually guide the centering process (e.g. visual servoing) and how to measure the alignment quality, but also, how to mechanically perform the alignment. Consequently, such systems are prone to being decentered by some offset, leading to challenging refraction patterns at the sphere that invalidate the pinhole camera model. We show that the overall camera system becomes an axial camera, even for thick domes as used for deep sea exploration and provide a non-iterative way to compute the center of refraction without requiring knowledge of exact air, glass or water properties. We also analyze the refractive geometry at the sphere, looking at effects such as forward- vs. backward decentering, iso-refraction curves and obtain a 6th-degree polynomial equation for forward projection of 3D points in thin domes. We then propose a pure underwater calibration procedure to estimate the decentering from multiple images. This estimate can either be used during adjustment to guide the mechanical position of the lens, or can be considered in photogrammetric underwater applications.

description: In this paper we use the latest corrections to the Newton-Einstein secular perihelion rates of some planets of the Solar System, phenomenologically estimated with the EPM2004 ephemerides by the Russian astronomer E.V. Pitjeva, to put severe constraints on the range parameter lambda characterizing the Yukawa-like modifications of the Newtonian inverse-square law of gravitation. It turns out that the range cannot exceed about one tenth of an Astronomical Unit. We assumed neither equivalence principle violating effects nor spatial variations of $α$ and $λ$. This finding may have important consequences on all the modified theories of gravity involving Yukawa-type terms with range parameters much larger than the Solar System size. However, caution is advised since we, currently have at our disposal only the periehlion extra-rates estimated by Pitjeva: if and when other groups will estimate their own corrections to the secular motion of perihelia, more robust and firm tests may be conducted.

description: High frequency velocity oscillations were observed in the spectral lines Fe I 543.45nm and 543.29nm, using 2D spectroscopy with a Fabry- Perot and speckle reconstruction, at the VTT in Tenerife. We investigate the radial component of waves with frequencies in the range 8 - 22mHz in the internetwork, network and a pore. We find that the occurrence of waves do not show any preference on location and are equally distributed over down-flows and up-flows, regardless of the activity of the observed area in the line of Fe I 543.45nm. The waves observed in the lower formed line of Fe I 543.29nm seem to appear preferentially over down-flows.

description: The azimuthal asymmetry of direct photons originating from primary hard scatterings between partons is calculated. This can be accounted for by the inclusion of the color dipole orientation, which is sensitive to the rapid variation of the nuclear profile. To this end we introduce the dipole orientation within the saturation model of Golec-Biernat and Wüsthoff, while preserving all its features at the cross-section level. We show that the direct photon elliptic anisotropy v2 coming from this mechanism changes sign and becomes negative for peripheral collisions, albeit it is quite small for nuclear collisions at the RHIC energy.

description: We study observational constraints on the non-metricity $f(Q)$-gravity which reproduces an exact $Λ$CDM background expansion history while modifying the evolution of linear perturbations. To this purpose we use Cosmic Microwave Background (CMB) radiation, baryonic acoustic oscillations (BAO), redshift-space distortions (RSD), supernovae type Ia (SNIa), galaxy clustering (GC) and weak gravitational lensing (WL) measurements. We set stringent constraints on the parameter of the model controlling the modifications to the gravitational interaction at linear perturbation level. We find the model to be statistically preferred by data over the $Λ$CDM according to the $χ^2$ and deviance information criterion statistics for the combination with CMB, BAO, RSD and SNIa. This is mostly associated to a better fit to the low-$\ell$ tail of CMB temperature anisotropies.

The double quasar Q2138-431: detection of a lensing galaxy

description: This paper reviews the question of whether the wide separation double quasar Q2138-431 is a gravitational lens. From early work, the two quasar images are known to have almost identical spectra and redshifts, but no lensing galaxy has so far been detected. In this paper we used recent deep surveys in infrared and optical bands to search for the presence of a galaxy with the expected properties of a gravitational lens. The search revealed a $5 σ$ detection of a faint galaxy between the two quasar images on a deep $J$-band frame from the VISTA Science Archive, with apparent magnitude $J = 20.68$. Non-detection in the $I$-band implied a redshift $z > 0.6$, and mass modelling of the quasar system gave a mass of $1.31 \times 10^{12} M_\odot$ for the lensing galaxy, with mass-to-light ratio $M_{\odot}/L_{\odot} = 9.0$. Archival photographic data from the UK 1.2m Schmidt telescope covering 25 years were used to construct light curves for the two quasar images, which were then cross-correlated to measure any time lag. This showed image B to lead image A by around a year, consistent with 410 days from the mass model. Although the similarity of the spectra and the detection of the lensing galaxy are the most compelling arguments for the classification of Q2138-431 as a gravitational lens, the time delay and mass-to-light ratio provide a consistent picture to support this conclusion. The wide separation of the quasar images and the simplicity of the mass model make Q2138-431 an excellent system for the measurement of the Hubble constant.

Whistles characteristics of common dolphins (Delphinus sp.)in the Hauraki Gulf, New Zealand
Creators: name: Petrella, Vincenzo
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2009

description: Quantifying the vocal repertoire of a species is critical for subsequent analysis of signal functionality, geographic variation and social relevance. Vocalisations of free-ranging common dolphins (Delphinus sp) have not previously been described from New Zealand waters. Herein, I present the first quantitative analysis of whistle characteristics to be undertaken on the New Zealand population. Acoustic data were collected in the Hauraki Gulf, Auckland between February 2008 and May 2009, during surveys from the tour boat Dolphin Explorer. Data were collected from 28 independent dolphin groups using PZ-1A hydrophone and MZ-NH700 digital audio disk. Recordings were analysed using Raven Pro 1.3 and whistles classified into seven contours containing 29 subtypes. A total of 105.1 minutes of recordings were collected involving 11,715 whistles. Vocalisations of New Zealand common dolphins spanned 3.2 to 23.00 kHz, with most whistles occurring between 11 and 13 kHz. The shortest and longest whistles recorded were 0.01 and 4.00 s (mean = 0.27, SD = 0.32), respectively. Of the twelve whistle types recorded, 82% have previously been recorded within U.K populations. Additional contours, apparently specific to New Zealand Delphinus were also identified. Of the 2,663 whistles analysed, downsweeps (35.9%) were the most frequent whistle type, followed by upsweeps (28.5%), constant (16.4%) and sine (7.0%) contours. Concave and convex contours were least observed within the New Zealand population, accounting for just 6.1% each. Of all the whistle types identified in Hauraki Gulf common dolphins, the least modulated subtypes were the most prevalent. Data presented here offer a first insight into the whistle characteristics of New Zealand common dolphins. Comparsions with previously studied populations reveal marked differences in the whistle frequency and modulation of the New Zealand population. Inter-population differences suggest behaviour and the local environment likely play a role in shaping the vocal repertoire of this species.

description: This paper provides an introduction to some stochastic models of lattice gases out of equilibrium and a discussion of results of various kinds obtained in recent years. Although these models are different in their microscopic features, a unified picture is emerging at the macroscopic level, applicable, in our view, to real phenomena where diffusion is the dominating physical mechanism. We rely mainly on an approach developed by the authors based on the study of dynamical large fluctuations in stationary states of open systems. The outcome of this approach is a theory connecting the non equilibrium thermodynamics to the transport coefficients via a variational principle. This leads ultimately to a functional derivative equation of Hamilton-Jacobi type for the non equilibrium free energy in which local thermodynamic variables are the independent arguments. In the first part of the paper we give a detailed introduction to the microscopic dynamics considered, while the second part, devoted to the macroscopic properties, illustrates many consequences of the Hamilton-Jacobi equation. In both parts several novelties are included.

description: A methodology Is presented in this thesis which addresses the water quality manager's problem of maximizing the biochemical oxygen demand loadings in reaches of a tidal river, subject to dissolved oxygen concentration regulation at various compliance levels. The non-linear tidal dynamics and BOD-DO processes were explicitly accounted for by numerical, finite-difference models incorporated as equality and inequality constraints of a non-linear programming problem solved by a direct search algorithm. This methodology was applied to the Nicomekl River in Surrey B.C., to investigate policy implications and its applicability, using a microcomputer, to the resolution of actual pollution management problems.

description: We study the two-dimensional kinematics of the H-alpha-emitting gas in the nearby barred Scd galaxy, NGC 6946, in order to determine the pattern speed of the primary m=2 perturbation mode. The pattern speed is a crucial parameter for constraining the internal dynamics, estimating the impact velocities of the gravitational perturbation at the resonance radii, and to set up an evolutionary scenario for NGC 6946. Our data allows us to derive the best fitting kinematic position angle and the geometry of the underlying gaseous disk, which we use to derive the pattern speed using the Tremaine-Weinberg method. We find a main pattern speed Omega_p=22 km/s/kpc, but our data clearly reveal the presence of an additional pattern speed Omega_p=47 km/s/kpc in a zone within 1.25 kpc of the nucleus. Using the epicyclic approximation, we deduce the location of the resonance radii and confirm that inside the outer Inner Lindblad Resonance radius of the main oval, a primary bar has formed rotating at more than twice the outer pattern speed. We further confirm that a nuclear bar has formed inside the Inner Lindblad Resonance radius of the primary bar, coinciding with the inner Inner Lindblad Resonance radius of the large-scale m=2 mode oval.

description: MegaRoller is a Horizon 2020 project which aims at developing and demonstrating a Power Take-off unit (PTO) able to increase the output from the few 100 kW range to a full 1 MW range. The project will generate extensive know-how in the area of PTO design and control systems, with the aim to decrease the levelized cost of energy of next generation Oscillating Wave Surge Converter devices. The project Work Package 5 – Validation & Impact Evaluation focuses on demonstrating that the models and technical solutions produced in the project meet the objectives issued regarding PTO performance, power quality, reliability, and cost reduction. Together with demonstration and validation activities (Tasks 5.1-5.3) and life-cycle cost assessment (Task 5.5), the project includes the evaluation of the environmental and socio-economic impacts expected from the MegaRoller device (Task 5.4). The present report builds on the Deliverable 2.61 which presented a method for EIA and SEIA for wave energy (WE) projects. The method was based on an exhaustive literature review on previous EIAs for similar installations, leading to the identification of a set of receptors and stressors potentially related to the development of nearshore wave energy devices, mitigation measures to be implemented, and monitoring techniques to be carried out. This report presents the development of an Environmental and Socioeconomic Impact Assessment Tool (ESIAT) and its application to the MegaRoller installation2 . The aim is for ESIAT to provide the environmental and socioeconomic impact assessment of the MegaRoller installation (including all stages of its development: preparation, construction, operation, decommissioning), allowing the developer, managers, and regulators for a quicker and more informed decision-making with regards to the mitigation of impacts that might come from the MegaRoller and to the monitoring of such impacts. The ESIAT was developed based on the findings from D2.6 and from further literature review carried out to include more recent developments on EIAs and monitoring activities undertaken for Marine Renewable Energy (MRE) projects and especially at WE installations. The impact assessment is provided by the ESIAT as a very extensive file; therefore, this report summarizes the assessment of the most significant impacts, the full assessment being attached to this report as Annex 1.

description: The paper proposes a new mathematical model of economic cycles and crises, which generalizes the well-known model of Dubovsky S.V. The novelty of the proposed model lies in taking into account the effect of heredity (memory), as well as the introduction of harmonic functions responsible for the arrival of investments in fixed assets and new management technologies in innovation. The mathematical description is given using the Gerasimov-Caputo fractional derivatives, which are studied within the framework of the theory of fractional calculus. The mathematical model was investigated using the numerical method of Adams-Bashforth-Moulton (ABM), phase trajectories were constructed. It is shown that the proposed mathematical model can have both regular and chaotic regimes.

description: This paper reports an application of gas-kinetic BGK scheme to the computation of turbulent compressible convection in the stellar interior. After incorporating the Sub-grid Scale (SGS) turbulence model into the BGK scheme, we tested the effects of numerical parameters on the quantitative relationships among the thermodynamic variables, their fluctuations and correlations in a very deep, initially gravity-stratified stellar atmosphere. Comparison indicates that the thermal properties and dynamic properties are dominated by different aspects of numerical models separately. An adjustable Deardorff constant in the SGS model $c_μ=0.25$ and an amplitude of artificial viscosity in the gas-kinetic BGK scheme $C_2=0$ are appropriate for current study. We also calculated the density-weighted auto- and cross-correlation functions in Xiong's (\cite{xiong77}) turbulent stellar convection theories based on which the gradient type of models of the non-local transport and the anisotropy of the turbulence are preliminarily studied. No universal relations or constant parameters were found for these models.

description: Sedimentologische und geochemische Untersuchungen eines Bodenprofils aus Dünensanden bei Rotenburg/Wümme (Niedersachsen) ermöglichen die Beschreibung von Verlagerungsprozessen in Podsolen. Daten der Elementverteilung bestätigen eine abwärts gerichtete Verlagerung der Sesquioxide (Aluminium, Eisen, Mangan) und des Nährstoffes Kalium aus den Auswaschungshorizonten des Oberbodens in die tiefer liegenden Anreicherungshorizonte. Darüber hinaus gelingt der Nachweis der Schwermetalle Zink und Titan im Oberboden. Beide Metalle sind ebenso wie die Zunahme von klastischen Partikeln in der Korngröße Silt nur durch windverlagerte und kontaminierte Stäube erklärbar. Die angewandten Methoden eignen sich zur Charakterisierung von natürlichen Prozessen in Bodenprofilen und können auch zur Interpretation von menschlichen Einflüssen herangezogen werden. Dieser methodische Ansatz kann ebenso zum Nachweis von veränderten Elementverteilungen, wie z. B. bei archäologischen Befunden, eingesetzt werden.

description: Assuming a two-component quasar structure model consisting of a central compact source and an extended outer feature, we produce microlensing simulations for a population of star-like objects in the lens galaxy. Such a model is a simplified version of that adopted to explain the brightness variations observed in Q0957 (Schild & Vakulik 2003). The microlensing light curves generated for a range of source parameters were compared to the light curves obtained in the framework of the OGLE program. With a large number of trials we built, in the domain of the source structure parameters, probability distributions to find "good" realizations of light curves. The values of the source parameters which provide the maximum of the joint probability distribution calculated for all the image components, have been accepted as estimates for the source structure parameters. The results favour the two-component model of the quasar brightness structure over a single compact central source model, and in general the simulations confirm the Schild-Vakulik model that previously described successfully the microlensing and other properties of Q0957. Adopting 3300 km/s for the transverse velocity of the source, the effective size of the central source was determined to be about 2x10^15 cm, and Epsilon =2 was obtained for the ratio of the integral luminosity of the outer feature to that of the central source.

description: Ziel dieses Beitrags ist es, die bisher vorhandenen Kenntnisse zu der fachlich kaum beachteten Dohrener Burg bei Heerstedt (Gemeinde Beverstedt, Lkr. Cuxhaven) zusammenzutragen und in Verbindung mit den aktuellen Sondenfunden das wissenschaftliche Potential eines als stark zerstört geltenden Fundplatzes zu diskutieren. Das Bild zeichnet eine für die Region typische Niederungsburg. Viele Fragen werden durch die weitgehend undokumentierte Planierung wohl ungeklärt bleiben. Dennoch steht die im ausgehenden 12. Jh. gegründete Burg nicht nur im Zusammenhang mit der Territorialgeschichte, sondern erlaubt auch über die Funde Rückschlüsse auf den Alltag und das Handwerk in der Burg. Teils vergoldete Pferdegeschirrbeschläge, eine Bronzeschale und ein Goldring weisen dabei auf das Standesbewusstsein der auf der Burg eingesetzten Ministerialen hin. Das vorliegende Ergebnis resultiert zuletzt aus einer sehr vertrauensvollen Zusammenarbeit zwischen kommunaler Denkmalpflege und ehrenamtlichen Sondengängern.

description: L'incessante evolversi degli strumenti e delle metodologie ha inevitabilmente imposto un approccio diverso nel settore della conoscenza e documentazione del patrimonio architettonico. In questo scenario, le dinamiche innescate dalle innovazioni tecnologiche, se da un lato stimolano la ricerca tecnico-scientifica ad approfondire le caratteristiche operative dei differenti strumenti, dall’altro generano un interessante confronto pluridisciplinare, orientato soprattutto ad indagare gli aspetti culturali generati dalla rivoluzione informatica, per ipotizzare possibili criteri di utilizzo delle nuove tecnologie.

description: The study of the observational properties of uncommonly long bursts from low luminosity sources with extended decay times up to several tens of minutes is important when investigating the transition from a hydrogen-rich bursting regime to a pure helium regime and from helium burning to carbon burning as predicted by current burst theories. IGR J17254-3257 is a recently discovered X-ray burster of which only two bursts have been recorded: an ordinary short type I X-ray burst, and a 15 min long burst. An upper limit to its distance is estimated to about 14.5 kpc. The broad-band spectrum of the persistent emission in the 0.3-100 keV energy band obtained using contemporaneous INTEGRAL and XMM-Newton data indicates a bolometric flux of 1.1x10^-10 erg/cm2/s corresponding, at the canonical distance of 8 kpc, to a luminosity about 8.4x10^35 erg/s between 0.1-100 keV, which translates to a mean accretion rate of about 7x10^-11 solar masses per year. The low X-ray persistent luminosity of IGR J17254-3257 seems to indicate the source may be in a state of low accretion rate usually associated with a hard spectrum in the X-ray range. The nuclear burning regime may be intermediate between pure He and mixed H/He burning. The long burst is the result of the accumulation of a thick He layer, while the short one is a prematurate H-triggered He burning burst at a slightly lower accretion rate.

description: We present the color-magnitude diagrams and star formation histories (SFHs) of seven ultra-faint dwarf galaxies: Horologium 1, Hydra 2, Phoenix 2, Reticulum 2, Sagittarius 2, Triangulum 2, and Tucana 2, derived from high-precision Hubble Space Telescope photometry. We find that the SFH of each galaxy is consistent with them having created at least 80% of the stellar mass by $z\sim6$. For all galaxies, we find quenching times older than 11.5 Gyr ago, compatible with the scenario in which reionization suppresses the star formation of small dark matter halos. However, our analysis also reveals some differences in the SFHs of candidate Magellanic Cloud satellites, i.e., galaxies that are likely satellites of the Large Magellanic Cloud and that entered the Milky Way potential only recently. Indeed, Magellanic satellites show quenching times about 600 Myr more recent with respect to those of other Milky Way satellites, on average, even though the respective timings are still compatible within the errors. This finding is consistent with theoretical models that suggest that satellites' SFHs may depend on their host environment at early times, although we caution that within the error bars all galaxies in our sample are consistent with being quenched at a single epoch.
