description: We present the Pan-STARRS1 discovery and light curves, and follow-up MMT and Gemini spectroscopy of an ultra-luminous supernova (ULSN; dubbed PS1-11bam) at a redshift of z=1.566 with a peak brightness of M_UV=-22.3 mag. PS1-11bam is one of the highest redshift spectroscopically-confirmed SNe known to date. The spectrum is characterized by broad absorption features typical of previous ULSNe (e.g., CII, SiIII), and by strong and narrow MgII and FeII absorption lines from the interstellar medium (ISM) of the host galaxy, confirmed by an [OII]3727 emission line at the same redshift. The equivalent widths of the FeII2600 and MgII2803 lines are in the top quartile of the quasar intervening absorption system distribution, but are weaker than those of gamma-ray burst intrinsic absorbers (i.e., GRB host galaxies). We also detect the host galaxy in pre-explosion Pan-STARRS1 data and find that its UV spectral energy distribution is best fit with a young stellar population age of tau~15-45 Myr and a stellar mass of M \sim (1.1-2.6)x10^9 M_sun (for Z=0.05-1 Z_sun). The star formation rate inferred from the UV continuum and [OII]3727 emission line is ~10 M_sun/yr, higher than in any previous ULSN host. PS1-11bam provides the first direct demonstration that ULSNe can serve as probes of the interstellar medium in distant galaxies. At the present, the depth and red sensitivity of PS1 are uniquely suited to finding such events at cosmologically interesting redshifts (z~1-2); the future combination of LSST and 30-m class telescopes promises to extend this technique to z~4.

The Origin of OB Runaway Stars

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: About 20% of all massive stars in the Milky Way have unusually high velocities, the origin of which has puzzled astronomers for half a century. We argue that these velocities originate from strong gravitational interactions between single stars and binaries in the centers of star clusters. The ejecting binary forms naturally during the collapse of a young ($\aplt 1$\,Myr) star cluster. This model replicates the key characteristics of OB runaways in our galaxy and it explains the $\apgt 100$\,\Msun\, runaway stars around young star clusters, e.g. R136 and Westerlund~2. The high proportion and the distributions in mass and velocity of runaways in the Milky Way is reproduced if the majority of massive stars are born in dense and relatively low-mass (5000-10000 \Msun) clusters.

description: From possibly as early as A.D. 700 to 1350, a complex series of population movements took many groups of Nahuat speakers from central and southern Mexico to Central America. In Guatemala, El Salvador, and Honduras, these groups were known as the Pipil. In Nicaragua they were called the Nicarao. For the purposes of this thesis, they are considered a single cultural entity, the Pipil-Nicarao, unified by a common cultural background, history, ideology, and language. There are sufficient archaeological, historical linguistic, and ethnohistoric data to write an ethnography of the ancient Pipil-Nicarao. The overall objective is to analyze and interpret data from various lines of inquiry-primarily archaeology, linguistics, and ethnohistory, but also geology, geography, environmental studies, botany, and zoology--and to weave the data together within an anthropological framework to create an ethnographic synthesis of Pipil-Nicarao culture, cultural adaptations, and history.

description: A significant fraction of massive stars are moving supersonically through the interstellar medium (ISM), either due to disruption of a binary system or ejection from their parent star cluster. The interaction of their wind with the ISM produces a bow shock. In late evolutionary stages these stars may undergo rapid transitions from red to blue and vice versa on the Hertzsprung-Russell diagram, with accompanying rapid changes to their stellar winds and bow shocks. Recent 3D simulations of the bow shock produced by the nearby runaway red supergiant (RSG) Betelgeuse, under the assumption of a constant wind, indicate that the bow shock is very young (<30000 years old), hence Betelgeuse may have only recently become a RSG. To test this possibility, we have calculated stellar evolution models for single stars which match the observed properties of Betelgeuse in the RSG phase. The resulting evolving stellar wind is incorporated into 2D hydrodynamic simulations in which we model a runaway blue supergiant (BSG) as it undergoes the transition to a RSG near the end of its life. We find that the collapsing BSG wind bubble induces a bow shock-shaped inner shell around the RSG wind that resembles Betelgeuse's bow shock, and has a similar mass. Surrounding this is the larger-scale retreating bow shock generated by the now defunct BSG wind's interaction with the ISM. We suggest that this outer shell could explain the bar feature located (at least in projection) just in front of Betelgeuse's bow shock.

description: We develop and subsequently explore the solution space of a simple flux transport dynamo model that incorporates a time dependent large scale meridional circulation. Based on recent observations we prescribed an analytical form for the amplitude of this circulation and study its impact in the evolution of the magnetic field. We find that cyclic variations in the amplitude and frequency of the meridional flow affect the strength of the solar cycle. Variations in the amplitude of the fluctuations influence the shape of the solar cycle but are only relevant to the cycle's strength variations when they occur at a frequency different from or out of phase of the solar cycle's.

description: We report Chandra observations of the Scd galaxy NGC 2139, which is known to host a recently formed (10^7.6 yrs) nuclear star cluster. The star cluster is undetected in X-rays, with an upper bound on 0.5-7 keV luminosity of L_X < 7.1 x 10^37 erg/s. This bound implies a bolometric accretion luminosity <0.3 percent of the Eddington luminosity for a black hole with the mass (approximately 3400 M_sun) expected from extrapolation of the M-sigma relation. The lack of X-ray emission indicates that a black hole, if present, is not undergoing significant accretion at the current time. While the central cluster is undetected, the data reveal a substantial population of bright X-ray point sources elsewhere in this galaxy, with eight qualifying as ultraluminous X-ray sources with L_X > 10^39 erg/s. We use archival Hubble Space Telescope images to identify candidate optical counterparts for seven Chandra sources, which in most cases have optical luminosities and spatial profiles consistent with star clusters. Compared with other galaxies, the number of luminous X-ray sources in NGC 2139 is larger by a factor of 4 - 10 than expected based on its present star formation rate and stellar mass. This finding can be understood if NGC 2139 has concluded a burst of star formation in the recent past, and suggests that this galaxy could be important for testing the use of X-ray source populations as a chronometer of star formation history.

description: (abridged) We present a clustering analysis of 370 high-confidence H-alpha emitters (HAEs) at z=2.23. The HAEs are detected in the Hi-Z Emission Line Survey (HiZELS), a large-area blank field 2.121um narrowband survey using the United Kingdom Infrared Telescope (UKIRT) Wide Field Camera (WFCAM). Averaging the two-point correlation function of HAEs in two ~1 degree scale fields (United Kingdom Infrared Deep Sky Survey/Ultra Deep Survey [UDS] and Cosmological Evolution Survey [COSMOS] fields) we find a clustering amplitude equivalent to a correlation length of r_0=3.7+/-0.3 Mpc/h for galaxies with star formation rates of >7 M_sun/yr. The data are well-fitted by the expected correlation function of Cold Dark Matter, scaled by a bias factor: omega_HAE=b^2 omega_DM where b=2.4^{+0.1}_{-0.2}. The corresponding 'characteristic' mass for the halos hosting HAEs is log(M_h/[M_sun/h])=11.7+/-0.1. Comparing to the latest semi-analytic GALFORM predictions for the evolution of HAEs in a LCDM cosmology, we find broad agreement with the observations, with GALFORM predicting a HAE correlation length of ~4 Mpc/h. Motivated by this agreement, we exploit the simulations to construct a parametric model of the halo occupation distribution (HOD) of HAEs, and use this to fit the observed clustering. Our best-fitting HOD can adequately reproduce the observed angular clustering of HAEs, yielding an effective halo mass and bias in agreement with that derived from the scaled omega_DM fit, but with the relatively small sample size the current data provide a poor constraint on the HOD. Our results support the broad picture that 'typical' (~L*) star-forming galaxies have been hosted by dark matter haloes with M_h<10^12 M_sun/h since z~2, but with a broad occupation distribution and clustering that is likely to be a strong function of luminosity.

description: The study identifies barriers hindering solar energy projects in Mexico and explores factors influencing public acceptance. Utilizing latent variables, the research reveals a correlation between low solar energy acceptance and government disinterest. Younger generations and higher education levels correlate with greater support for environmental conservation and solar projects. The findings emphasize the need for proactive strategies by policymakers, project developers, and stakeholders. The conclusion highlights the government's pivotal role, suggesting actions such as providing financial incentives and promoting solar initiatives to enhance public trust and acceptance. Ultimately, the research aims to guide effective measures fostering confidence in solar energy projects.
Efficient Matrix-Element Matching with Sector Showers

description: A Markovian shower algorithm based on "sector antennae" is presented and its main properties illustrated. Tree-level full-color matrix elements can be automatically incorporated in the algorithm and are re-interpreted as process-dependent 2 -> n antenna functions. In hard parts of phase-space, these functions generate tree-level matrix-element corrections to the shower. In soft parts, they should improve the logarithmic accuracy of it. The number of matrix-element evaluations required per order of matching is 1, with an unweighting efficiency that remains very high for arbitrary numbers of legs. Total rates can be augmented to NLO precision in a straightforward way. As a proof of concept, we present an implementation in the publicly available VINCIA plug-in to the PYTHIA 8 event generator, for hadronic $Z^0$ decays including tree-level matrix elements through ${\cal O}(α_s^4)$.

description: Using a framework in which all elements are constrained by Dyson-Schwinger equation studies in QCD, and therefore incorporates a consistent, direct and simultaneous description of light- and heavy-quarks and the states they constitute, we analyze the accuracy of SU(4)-flavor symmetry relations between πρπ, KρK and DρD couplings. Such relations are widely used in phenomenological analyses of the interactions between matter and charmed mesons. We find that whilst SU(3)-flavor symmetry is accurate to 20%, SU(4) relations underestimate the DρD coupling by a factor of five.

Choosing a representation of the problem addressed, an initial population, a method of selection, a crossover operator, mutation operator, the probabilities of crossover and mutation, and the insertion method creates a variant of genetic algorithms. Our work is part of the answer to this perspective to find a solution for this combinatorial problem. What are the best parameters to select for a genetic algorithm that creates a variety efficient to solve the Travelling Salesman Problem (TSP)? In this paper, we present a comparative analysis of different mutation operators, surrounded by a dilated discussion that justifying the relevance of genetic operators chosen to solving the TSP problem.

description: We present an analytical model describing complex dynamics of a hybrid nonlinear system consisting of interacting carbon nanotubes (CNT) and a plasmonic metamaterial. Our model is based on the set of coupled equations, which incorporates well-established density matrix formalism appropriate for quantum systems (CNT are described as a two level system) and harmonic-oscillator approach ideal for modelling sub-wavelength plasmonic and optical resonators. We show that the saturation nonlinearity of CNT increases multifold in the resonantly enhanced near field of a metamaterial. In the framework of our model, we discuss the effect of inhomogeneity of the CNT layer (band gap value distribution) on the nonlinearity enhancement. It is shown, that the Purcell effect is indistinguishable from the field enhancement and is described by the same phenomenological constant.

description: The first stars fundamentally transformed the early universe by emitting the first light and by producing the first heavy elements. These effects were predetermined by the mass distribution of the first stars, which is thought to have been fixed by a complex interplay of gas accretion and protostellar radiation. We performed radiation-hydrodynamics simulations that followed the growth of a primordial protostar through to the early stages as a star with thermo-nuclear burning. The circumstellar accretion disk was evaporated by ultraviolet radiation from the star when its mass was 43 times that of the Sun. Such massive primordial stars, in contrast to the often postulated extremely massive stars, may help explain the fact that there are no signatures of the pair-instability supernovae in abundance patterns of metal-poor stars in our galaxy.

We observe the longest spin relaxation times tau_S in monolayer graphene, while the spin diffusion coefficient D_S is strongly reduced compared to typical results on exfoliated graphene. The increase of tau_S is probably related to the changed substrate, while the cause for the small value of D_S remains an open question.

description: We propose a framework for natural breaking of electroweak symmetry in supersymmetric models, where elementary Higgs fields are semi-perturbatively coupled to a strong superconformal sector. The Higgs VEVs break conformal symmetry in the strong sector at the TeV scale, and the strong sector in turn gives important contributions to the Higgs potential, giving rise to a kind of Higgs bootstrap. A Higgs with mass $125\GeV$ can be accommodated without any fine tuning. A Higgsino mass of order the Higgs mass is also dynamically generated in these models. The masses in the strong sector generically violate custodial symmetry, and a good precision electroweak fit requires tuning of order $\sim 10%$. The strong sector has an approximately supersymmetric spectrum of hadrons at the TeV scale that can be observed by looking for a peak in the $WZ$ invariant mass distribution, as well as final states containing multiple $W$, $Z$, and Higgs bosons. The models also generically predict large corrections (either enhancement or suppression) to the $h \to \ga\ga$ width.

description: FAIR principles are now integral to handling research data, with ongoing challenges notwithstanding. However, the FAIR Principles, at a high level, are intended to apply to all research objects; both those used in research and those that are research outputs. Here we highlight the efforts around FAIR research software as well as Machine Learning, while emphasising the need for community-led standards and best practices in this area.

description: We study the time evolution of entangled states of a pair of identical atoms, considered in the harmonic approximation, coupled to an environment represented by an infinite set of free oscillators, with the whole system confined within a spherical cavity of radius $R$. Taking the center-of-mass and the relative-position coordinates, and using the dressed-state approach, we present the time evolution of some quantities measuring the entanglement, for both limits of a very large and a small cavity; the chosen examples are simple and illustrate these very distinct behaviors.

description: The principal objective of this study was to provide low temperature oxidation reaction models which are suitable for use in numerical simulators of in situ combustion for the Alberta's Athabasca oil sands. For the first time, in the literature, a systematic study was carried out to investigate the low temperature oxidation reactions of the liquid phase components of bitumen or heavy oils. Athabasca bitumen, free of water and minerals, was oxidized using a stirred semiflow batch reactor. Reactions were carried out in the 60°c to 1S0°c temperature range and at oxygen partial pressures of 40 kPa to 2233 kPa. The total pressures applied in the reactor ranged from 2190 kPa to 4415 kPa. Experimental data were collected in the kinetic subregime. Reactor product gas analysis was carried out using a gas chromatograph and the liquid phase oxidation product was separated into six main components (lumped components): saturates, aromatics, resins I, resins II, asphaltenes and coke. Experimental runs were made at 1S0°C, 135°c, 120°c, 105°c and 60°c, and at each temperature reactions were terminated after varying degrees of oxidation or reaction extent. Time dependent product distribution curves show that the reactions involving the liquid phase components are consecutive. The oxidation reactions were dependent on oxygen partial pressures and were independent of the total pressure in the reactor. Elemental analysis and spectroscopy tests were carried out for selected oxidized bitumen samples in an attempt to understand the chemistry of the complex oxidation reactions. Results of these tests suggest that the liquid phase products were formed through condensation, oxygen incorporation and polymerization reactions. For the first time, in the literature, kinetic models have been established for the liquid phase reaction components involved in the low temperature oxidation reactions of a mixture of complex hydrocarbons. Based on the experimental kinetic data, two main types of reaction models are proposed. These are: i) A non-steady state kinetic model to represent the overall rate of oxygen consumption. This model is second order with respect to oxygen partial pressure. ii) Four non-steady state multiresponse kinetic models representing the oxidation reactions of the liquid phase components. These components include, maltenes, oils, the resins and asphaltenes-coke. The models are first order with respect to the lumped components and fractional order in oxygen partial pressure. The invariant kinetic parameters in the models were estimated using the maximum likelihood techniques. statistically adequate. Proposed models were found.

description: We present a theoretical study of the conductance and thermopower of single-molecule junctions based on C60 and C60-terminated molecules. We first analyze the transport properties of gold-C60-gold junctions and show that these junctions can be highly conductive (with conductances above 0.1G0, where G0 is the quantum of conductance). Moreover, we find that the thermopower in these junctions is negative due to the fact that the LUMO dominates the charge transport, and its magnitude can reach several tens of micro-V/K, depending on the contact geometry. On the other hand, we study the suitability of C60 as an anchoring group in single-molecule junctions. For this purpose, we analyze the transport through several dumbbell derivatives using C60 as anchors, and we compare the results with those obtained with thiol and amine groups. Our results show that the conductance of C60-terminated molecules is rather sensitive to the binding geometry. Moreover, the conductance of the molecules is typically reduced by the presence of the C60 anchors, which in turn makes the junctions more sensitive to the functionalization of the molecular core with appropriate side groups.

description: The main result of the present paper is a statement on existence, uniqueness and regularity for mild solutions to a parabolic transport diffusion type equation that involves a non-smooth coefficient. We investigate related Cauchy problems on bounded smooth domains with Dirichlet boundary conditions by means of semigroup theory and fixed point arguments. Main ingredients are the definition of a product of a function and a (not too irregular) distribution as well as a corresponding norm estimate. As an application, transport stochastic partial differential equations driven by fractional Brownian noises are considered in the pathwise sense.

Floquet Engineering Topological Many-Body Localized Systems

description: We show how second-order Floquet engineering can be employed to realize systems in which many-body localization coexists with topological properties in a driven system. This allows one to implement and dynamically control a symmetry protected topologically ordered qubit even at high energies, overcoming the roadblock that the respective states cannot be prepared as ground states of nearest-neighbor Hamiltonians. Floquet engineering—the idea that a periodically driven nonequilibrium system can effectively emulate the physics of a different Hamiltonian—is exploited to approximate an effective three-body interaction among spins in one dimension, using time-dependent two-body interactions only. In the effective system, emulated topology and disorder coexist, which provides an intriguing insight into the interplay of many-body localization that defies our standard understanding of thermodynamics and into the topological phases of matter, which are of fundamental and technological importance. We demonstrate explicitly how combining Floquet engineering, topology, and many-body localization allows one to harvest the advantages (time-dependent control, topological protection, and reduction of heating, respectively) of each of these subfields while protecting them from their disadvantages (heating, static control parameters, and strong disorder).
Formation Of The Rare Earth Peak: Gaining Insight Into Late-Time r-Process Dynamics

description: We study the formation and final structure of the rare earth peak ($A\sim160$) of the $r$-process nucleosynthesis. The rare earth peak forms at late times in the $r$-process after neutron exhaustion (neutron-to-seed ratio unity or R=1) as matter decays back to stability. Since rare earth peak formation does not occur during \nggn \ equilibrium it is sensitive to the strong interplay between late time thermodynamic evolution and nuclear physics input. Depending on the conditions the peak forms either because of the pattern of the neutron capture rates or because of the pattern of the separation energies. We analyze three mass models under different thermodynamic conditions. We find that the subtleties of each mass model, including separation energies and neutron capture rates, influence not only the final shape of the peak but also when it forms. We identify the range of nuclei which are influential in rare earth peak formation.

description: We establish new local regularity results for the harmonic map and Yang–Mills heat flows on Riemannian manifolds of dimension greater than 2 and 4, respectively, obtaining criteria for the smooth local extensibility of these flows. As a corollary, we obtain new characterisations of singularity formation and use this to obtain a local estimate on the Hausdorff measure of the singular sets of these flows at the first singular time. Finally, we show that smooth blow-ups at rapidly forming singularities of these flows are necessarily nontrivial and admit a positive lower bound on their heat ball energies. These results crucially depend on some local monotonicity formulæ for these flows recently established by Ecker (Calc Var Partial Differ Equ 23(1):67–81, 2005) and the Afuni (Calc Var 555(1):1–14, 2016; Adv Calc Var 12(2):135–156, 2019).

description: Wenn im allgemeinen Sprachgebrauch von Strukturwandel gesprochen wird, dann sind in der Regel die mit der marktwirtschaftlichen Dynamik verbundenen, mehr oder weniger stetigen Veränderungen der wertmäßigen Beiträge der einzelnen Wirtschaftszweige und -sektoren zum Sozialprodukt gemeint. Der Begriff Strukturwandel kann sich in diesem Sinne auf die veränderte Zusammensetzung der Produktion eines Landes (Produktionsstruktur) nach Wirtschaftszweigen (sektorale Struktur) oder nach Regionen und Wirtschaftsräumen (regionale Struktur) beziehen.

Der Strukturwandel kann auch als Maß für den Entwicklungsstand einer Volkswirtschaft gelten, da er wesentlich durch den technologischen Fortschritt beeinflusst wird. Die Einführung neuer Technologien verändert in der Regel die Produktionsprozesse und die damit einhergehende Nachfrage nach Erwerbstätigen. In weniger entwickelten Ländern zeigt sich der Strukturwandel vorrangig in einem Wegfall von Arbeitsplätzen in der Landwirtschaft zugunsten eines Arbeitsplatzaufbaus in der Industrie. Mit zunehmender technologischer Entwicklung ergeben sich jedoch auch verstärkt Rationalisierungsmöglichkeiten bei der Herstellung von Waren, während Arbeitsplätze im Dienstleistungsbereich aufgebaut werden. Im weiteren Sinne beschreibt der Begriff Strukturwandel die Transformation in eine Dienstleistungsgesellschaft, die sich in jeder Veränderung der Aufteilung der Beschäftigten (Erwerbsstruktur, Beschäftigungsstruktur) nach Sektoren, Regionen, Berufen oder Qualifikationsanforderungen zeigt.

Obwohl der strukturelle Wandel einen starken Zusammenhang mit dem technologischen Fortschritt aufweist, wird er nicht allein durch diesen verursacht. Wie und was wir in Zukunft produzieren
bzw. welche Dienstleistungen wir in Zukunft anbieten werden und auf welche Weise, hängt von einer Reihe von Einflussfaktoren ab. Diese sogenannten Megatrends sind dadurch gekennzeichnet,
dass sie unser Leben in allen möglichen Bereichen für die nächsten 20 bis 30 Jahre bestimmen werden und ein globales Phänomen darstellen. Neben dem technischen Fortschritt (zum Beispiel Digitalisierung, Smart City, neue Mobilitätskonzepte) sind maßgebliche Megatrends die demografische Entwicklung (zum Beispiel Schrumpfung, Alterung, Gesundheit, [De-]Urbanisierung), die Globalisierung, der Klimawandel (verbunden mit den Klimafolgenanpassungen) sowie gesellschaftliche Veränderungen (zum Beispiel Integration häuslicher Dienste wie Pflege und Erziehung in den Arbeitsmarkt, Frauenerwerbstätigkeit, Individualisierung, Work-Life-Balance). Die aktuelle COVID-19-Pandemie wird zwar auch mittel- und langfristige Verhaltensänderungen nach sich ziehen, die das Tempo der Megatrends womöglich beeinflussen, eine Trendumkehr erscheint derzeit allerdings als eher unwahrscheinlich.
