description: Terahertz (THz) and sub-THz frequency emitter and detector technologies are receiving increasing attention, underpinned by emerging applications in ultra-fast THz physics, frequency-combs technology and pulsed laser development in this relatively unexplored region of the electromagnetic spectrum. In particular, semiconductor-based ultrafast THz receivers are required for compact, ultrafast spectroscopy and communication systems, and to date, quantum well infrared photodetectors (QWIPs) have proved to be an excellent technology to address this given their intrinsic ps-range response However, with research focused on diffraction-limited QWIP structures (lambda/2), RC constants cannot be reduced indefinitely, and detection speeds are bound to eventually meet un upper limit. The key to an ultra-fast response with no intrinsic upper limit even at tens of GHz is an aggressive reduction in device size, below the diffraction limit. Here we demonstrate sub-wavelength (lambda/10) THz QWIP detectors based on a 3D split-ring geometry, yielding ultra-fast operation at a wavelength of around 100 μm. Each sensing meta-atom pixel features a suspended loop antenna that feeds THz radiation in the ~20 m3 active volume. Arrays of detectors as well as single-pixel detectors have been implemented with this new architecture, with the latter exhibiting ultra-low dark currents below the nA level. This extremely small resonator architecture leads to measured optical response speeds - on arrays of 300 devices - of up to ~3 GHz and an expected device operation of up to tens of GHz, based on the measured S-parameters on single devices and arrays.

Hypercharge Flux in IIB and F-theory: Anomalies and Gauge Coupling Unification

description: We analyse hypercharge flux GUT breaking in F-theory/Type IIB GUT models with regards to its implications for anomaly cancellation and gauge coupling unification. To this aim we exploit the Type IIB limit and consider 7-brane configurations that for the first time are guaranteed to exhibit net hypercharge flux restriction to matter curves. We show that local F-theory models with anomalies of type U(1)_Y-U(1)^2 in the massless spectrum can be consistent only if such additional U(1)s are globally geometrically massive (in the sense that they arise from non-Kahler deformations of the Calabi-Yau four-fold). Further, in such cases of geometrically massive U(1)s hypercharge flux can induce new anomalies of type U(1)_Y^2-U(1) in the massless spectrum, violating constraints in local models forbidding such anomalies. In particular this implies that it is possible to construct models exhibiting a U(1)_{PQ} global symmetry which have hypercharge flux doublet-triplet splitting and no further exotics. We also show that the known hypercharge flux induced splitting of the gauge couplings in IIB models at tree-level can be reduced by a factor of 5 by employing a more F-theoretic twisting of U(1) flux by hypercharge flux bringing it to well within MSSM 2-loop results. In the case of net restriction of hypercharge flux to matter curves this tree-level splitting becomes more involved, is tied to the vacuum expectation values of certain closed-string fields, and therefore gauge coupling unification becomes tied to the question of moduli stabilisation.

description: The rare phenomenon of ribbon-like hard X-ray (HXR) sources up to 100 keV found in the 2005 May 13 M8.0 flare observed with the \textit{Reuven Ramaty High Energy Solar Spectroscopic Imager} provides detailed information on the spatial distribution of flare HXR emission. In this Letter, we further investigate the characteristics of HXR emission in this event using imaging spectroscopy, from which we obtain spatially resolved HXR spectral maps during the flare impulsive phase. As a result we found, along a flare ribbon, an anticorrelation relationship between the local HXR flux and the local HXR spectral index. We suggest that this can be regarded as a spatial analog of the well-known temporal soft-hard-soft spectral evolution pattern of the integrated HXR flux. We also found an anticorrelation between HXR spectral index and local electric field along the ribbon, which suggests the electron acceleration by the electric field during flares.

description: W is a systematic approach toward the construction of event-driven, interactive, real-time software. W is driven by practical concerns, including the desire to reuse existing code wherever possible, the limited real-time software support in popular operating systems, and system cost. W provides a simple, efficient, software interconnection system, giving objects a uniform external interface based on setting attributes to values via asynchronous messages. An example shows how W is used to implement real-time computer music programs combining graphics and MIDI.

description: In the hierarchical paradigm of structure formation, galaxy clusters are the largest objects ever to virialize. They are thought to grow by accreting mass through large scale, strong virial shocks. Such a collisionless shock is expected to accelerate relativistic electrons, thus generating a spectrally flat leptonic virial ring. However attempts to detect virial rings have all failed, leaving the shock paradigm unconfirmed. Here we identify a virial $γ$-ray signal by stacking Fermi-LAT data for 112 clusters, enhancing the ring sensitivity by rescaling clusters to their virial radii and utilizing the anticipated spectrum. In addition to a central unresolved, hard signal (detected at the nominal $5.8σ$ confidence level), probably dominated by active galactic nuclei, we identify ($5.9σ$) a bright, spectrally flat $γ$-ray ring at the expected shock position. It corresponds to $\sim 0.6\%$ (with an uncertainty factor $\sim2$) thermal energy deposition in relativistic electrons over a Hubble time. This result validates the shock paradigm, calibrates its parameters, and indicates that the cumulative emission from such shocks significantly contributes to the diffuse extragalactic $γ$-ray and radio backgrounds.

description: The Tillinghast Reflector Echelle Spectrograph (TRES) is a fiber-fed optical spectrograph with a resolution of 44,000. TRES is a workhorse for recon spectroscopy as part of the TESS Follow-up Observing Program (TFOP). To date, over 2500 spectra of over 1000 TOIs have been obtained with TRES. In addition, over 200 TOIs have been observed with the Fiber-fed Echelle Spectrograph (FIES). These spectra are carefully examined to search for possible false positives such as double-lined spectra or targets that show large velocity variation indicating a stellar companion. The spectra are also used to derive stellar parameters using the Stellar Parameter Classification (SPC) tool. Extracted spectra along with quick-look stellar classification plots from the TRES pipeline are uploaded to ExoFOP-TESS weekly to encourage community collaboration. A full SPC analysis of all TRES and FIES spectra is being run to provide effective temperature, surface gravity, projected rotational velocity and metallicity. A quality flag indicator will also be applied to the classifications based on the quality of the data and the stellar type/parameters. These parameters will be uploaded to ExoFOP-TESS once the analysis is complete for community use.

description: We have found that individual presolar silicon carbide (SiC) dust grains from supernovae show a positive correlation between 49Ti and 28Si excesses, which is attributed to the radioactive decay of the short-lived (t1/2=330 day) 49V to 49Ti in the inner highly 28Si-rich Si/S zone. The 49V-49Ti chronometer constrains that these supernova SiC dust grains formed at least two years after their parent stars exploded. This result supports recent dust condensation calculations that predict a delayed formation of carbonaceous and SiC grains in supernovae. The astronomical observation of continuous buildup of dust in supernovae over several years can, therefore, be interpreted as a growing addition of C-rich dust to the dust reservoir in supernovae.

description: We present JHK$_{s}$ observations of the metal-poor ([Fe/H] $10^{-11}$ $M_\odot \,{\rm yr}^{-1}$, confirming that metal-poor stars can form substantial amounts of dust. We also find tentative evidence for oxygen-rich dust formation at low metallicity, contradicting previous models that suggest oxygen-rich dust production is inhibited in metal-poor environments. The total rates of dust injection into the interstellar medium of Leo A and Sextans A are (8.2 $\pm$ 1.8) $\times 10^{-9}$ $M_\odot \,{\rm yr}^{-1}$ and (6.2 $\pm$ 0.2) $\times 10^{-7}$ $M_\odot \,{\rm yr}^{-1}$, respectively. The majority of this dust is produced by a few very dusty evolved stars, and does not vary strongly with metallicity.

description: The edge physics of graphene based systems is well known to be highly sensitive to the atomic structure at the boundary, with localized zero mode edge states found only on the zigzag type termination of the lattice. Here we demonstrate that the graphene twist bilayer supports an additional class of edge states, that (i) are found for all edge geometries and thus are robust against edge roughness, (ii) occur at energies coinciding with twist induced van Hove singularities in the bulk and (iii) possess an electron density strongly modulated by the moiré lattice. Interestingly, these "moiré edge states" exist only for certain lattice commensurations and thus the edge physics of the twist bilayer is, in dramatic contrast to that of the bulk, not uniquely determined by the twist angle.

description: Most music processing attempts to focus on one particular feature or structural element such as pitch, beat location, tempo, or genre. This hierarchical approach, in which music is separated into elements that are analyzed independently, is convenient for the scientific researcher, but is at odds with intuition about music perception. Music is interconnected at many levels, and the interplay of melody, harmony, and rhythm are important in perception. As a first step toward more holistic music analysis, music structure is used to constrain a beat tracking program. With structural information, the simple beat tracker, working with audio input, shows a large improvement. The implications of this work for other music analysis problems are discussed.

description: The shape and periodic nature of stellar light curves can uncover important information about a star’s intrinsic properties, in addition to revealing possible companions. TESS has obtained high-precision space-based time-series photometry of nearly the entire sky, allowing for a large-scale study of stellar variability that is not sensitive to the diurnal limitation of ground-based surveys. We search for periodicity in ~230,000 stars that were observed at 2-minute cadence during the TESS primary mission and identify ~55,000 stars with significant sinusoidal variability on timescales of 0.01-13 days that could be attributed to rotational modulations, stellar pulsations, or binarity. We will discuss the population statistics for stars in our sinusoidal stellar variability catalog and make comparisons with those at similar timescales (<13 days) detected by Kepler. Our stellar variability catalog will be a valuable resource to the stellar astrophysics and exoplanet communities, in that it will aid 1) studying the characteristics of periodic variable stars; 2) understanding interactions between host star variability and planetary atmospheres; and 3) identifying false positives caused by stellar variability for future planet candidates.

description: We report a single crystal neutron and x-ray diffraction study of the hybrid improper multiferroic Ca3Mn1.9Ti0.1O7 (CMTO), a prototypical system where the electric polarization arises from the condensation of two lattice distortion modes.With increasing temperature (T ), the out-of-plane, antiphase tilt of MnO6 decreases in amplitude while the in-plane, in-phase rotation remains robust and experiences abrupt changes across the first-order structural transition. Application of hydrostatic pressure (P) to CMTO at room temperature shows a similar effect. The consistent behavior under both T and P reveals the softness of antiphase tilt and highlights the role of the partially occupied d orbital of the transition-metal ions in determining the stability of the octahedral distortion. Polarized neutron analysis indicates the symmetry-allowed canted ferromagnetic moment is less than the 0.04 μB/Mn site, despite a substantial out-of-plane tilt of the MnO6 octahedra.

description: The Higgs branch of minimally supersymmetric five dimensional SQCD theories increases in a significant way at the UV fixed point when the inverse gauge coupling is tuned to zero. It has been a long standing problem to figure out how, and to find an exact description of this Higgs branch. This paper solves this problem in an elegant way by proposing that the Coulomb branches of three dimensional ${\cal N}=4$ supersymmetric quiver gauge theories, named "Exceptional Sequences", provide the solution to the problem. Thus, once again, 3d ${\cal N}=4$ Coulomb branches prove to be useful tools in solving problems in higher dimensions. Gauge invariant operators on the 5d side consist of classical objects such as mesons, baryons and gaugino bilinears, and non perturbative objects such as instanton operators with or without baryon number. On the 3d side we have classical objects such as Casimir invariants and non perturbative objects such as monopole operators, bare or dressed. The duality map works in a very interesting way.

description: TESS is poised to increase the number of stellar rotation period estimates by an order of magnitude, but the mission’s systematics have complicated period searches. While several efforts attempt to solve this problem by removing systematics, standard methods of data reduction have shown limited success. Here I present a method to predict rotation periods from TESS full-frame image light curves using deep learning. This method relies on a training set of simulated light curves convolved with TESS galaxy light curves to emulate the instrumental noise and systematics observed in stellar signals. The simulations include surface differential rotation, spot evolution, and activity level to make the light curves as realistic as possible. Our approach allows the network to learn the difference between rotation signals and TESS systematics. With the added ability to predict uncertainty in the period, we can determine what regions of parameter space the predictions are most credible, producing a reliable set of rotation periods. I present the first set of rotation periods obtained with this method and explore TESS’s insights to stellar structure and evolution through the lens of rotation.

description: Provenance techniques aim to increase the reliability of human judgments about data by making its origin and derivation process explicit. Originally motivated by the needs of scientific databases and scientific computation, provenance has also become a major issue for business and government data on the Web. However, so far provenance has been studied only in relatively restrictive settings: typically, for data stored in databases or scientific workflow systems, and processed by query or workflow languages of limited expressiveness. Long-term provenance solutions require an understanding of provenance in other settings, particularly the general-purpose programming or scripting languages that are used to glue different components such as databases, Web services and workflows together. Moreover, what is required is not only an account of mechanisms for recording provenance, but also a theory of what it means for provenance information to explain or justify a computation. In this paper, we begin to outline a such a theory of self-explaining computation. We introduce a model of provenance for a simple imperative language based on operational derivations and explore its properties.

description: We present results from the optical, ultraviolet and X-ray monitoring of the NLS1 galaxy IRAS 13224-3809 taken with Swift and XMM-Newton during 2016. IRAS 13224-3809 is the most variable bright AGN in the X-ray sky and shows strong X-ray reflection, implying that the X-rays strongly illuminate the inner disc. Therefore, it is a good candidate to study the relationship between coronal X-ray and disc UV emission. However, we find no correlation between the X-ray and UV flux over the available ~40 day monitoring, despite the presence of strong X-ray variability and the variable part of the UV spectrum being consistent with irradiation of a standard thin disc. This means either that the X-ray flux which irradiates the UV emitting outer disc does not correlate with the X-ray flux in our line of sight and/or that another process drives the majority of the UV variability. The former case may be due to changes in coronal geometry, absorption or scattering between the corona and the disc.

description: We study adaptive dynamics in games where players abandon the population at a given rate, and are replaced by naive players characterized by a prior distribution over the admitted strategies. We demonstrate how such process leads macroscopically to a variant of the replicator equation, with an additional term accounting for player turnover. We study how Nash equilibria and the dynamics of the system are modified by this additional term, for prototypical examples such as the rock-scissor-paper game and different classes of two-action games played between two distinct populations. We conclude by showing how player turnover can account for non-trivial departures from Nash equilibria observed in data from lowest unique bid auctions.

description: The exoplanet yield of the TESS mission is expected to surpass that of Kepler, and the relatively bright stars observed by TESS will be significantly more amenable to RV follow-up. Yet TESS is more sensitive to detection biases than its predecessor, as close to 75% of the sky coverage of the TESS primary mission has a continuous time baseline of just 27 days. In these regions of the sky, TESS will observe no more than a single transit for any exoplanet with an orbital period longer than a month. The orbital parameters that can be derived for these “single-transit planet candidates” (STPCs) will be poorly constrained relative to those derived for exoplanets observed to transit multiple times, posing a challenge for follow-up observations. But long-period planets are nevertheless worth confirming and characterizing. Here, I present a framework for maximizing the efficiency of RV observations of STPCs. By leveraging information on exoplanet populations from Kepler, I show that one can develop an informed follow-up strategy even without strong constraints on the orbital period or eccentricity. I also highlight how this information can be used to design dynamic, adaptive observing schemes for queue-based instruments such as NEID.

description: Module systems for languages with complex type systems, such as Standard ML, often lack the ability to express mutually recursive type and function dependencies across module boundaries. Previous work by Crary, Harper and Puri [5] set out a type-theoretic foundation for recursive modules in the context of a phase-distinction calculus for higher-order modules. Two constructs were introduced for encoding recursive modules: a fixed-point module and a recursively dependent signature. Unfortunately, the implementations of both constructs involve the use of equi-recursive type constructors at higher-order kinds, the equivalence of which is not known to be decidable. In this paper, we show that the practicality of recursive modules is not contingent upon that of equi-recursive constructors. We begin with the theoretical infrastructure described above and study precisely how equi-recursiveness is used in the recursive module constructs, resulting in a clarification and generalization of the underlying ideas. We then examine in depth how the recursive module constructs in the revised type system can serve as the target of elaboration for a recursive module extension to Standard ML.

description: We address the question whether the ILC can resolve the LHC Inverse Problem within the framework of the MSSM. We examine 242 points in the MSSM parameter space which were generated at random and were found to give indistinguishable signatures at the LHC. After a realistic simulation including full Standard Model backgrounds and a fast detector simulation, we find that roughly only one third of these scenarios lead to visible signatures of some kind with a significance $\geq 5$ at the ILC with $\sqrt s=500$ GeV. Furthermore, we examine these points in parameter space pairwise and find that only one third of the pairs are distinguishable at the ILC at $5σ$.

description: We present an inductively coupled-plasma reactive-ion etching process that simultaneously provides both a high etch rate and unprecedented selectivity for gallium phosphide (GaP) in the presence of aluminum gallium phosphide (Al$_\textrm{x}$Ga$_{1-\textrm{x}}$P). Utilizing mixtures of silicon tetrachloride (SiCl$_4$) and sulfur hexafluoride (SF$_6$), selectivities exceeding 2700:1 are achieved at GaP etch rates above 3000 nm/min. A design of experiments has been employed to investigate the influence of the inductively coupled-plasma power, the chamber pressure, the DC bias and the ratio of SiCl$_4$ to SF$_6$. The process enables the use of thin Al$_\textrm{x}$Ga$_{1-\textrm{x}}$P stop layers even at aluminum contents of a few percent.

A matched filter approach for blind joint detection of galaxy clusters in X-ray and SZ surveys

description: The combination of X-ray and SZ observations can potentially improve the cluster detection efficiency when compared to using only one of these probes, since both probe the same medium: the hot ionized gas of the intra-cluster medium. We present a method based on matched multifrequency filters (MMF) for detecting galaxy clusters from SZ and X-ray surveys. This method builds on a previously proposed joint X-ray-SZ extraction method (Tarrío et al. 2016) and allows to blindly detect clusters, that is finding new clusters without knowing their position, size or redshift, by searching on SZ and X-ray maps simultaneously. The proposed method is tested using data from the ROSAT all-sky survey and from the Planck survey. The evaluation is done by comparison with existing cluster catalogues in the area of the sky covered by the deep SPT survey. Thanks to the addition of the X-ray information, the joint detection method is able to achieve simultaneously better purity, better detection efficiency and better position accuracy than its predecessor Planck MMF, which is based on SZ maps only. For a purity of 85%, the X-ray-SZ method detects 141 confirmed clusters in the SPT region, whereas to detect the same number of confirmed clusters with Planck MMF, we would need to decrease its purity to 70%. We provide a catalogue of 225 sources selected by the proposed method in the SPT footprint, with masses ranging between 0.7 and 14.5 $\cdot 10^{14}$ Msun and redshifts between 0.01 and 1.2.

Cold giants around M dwarfs: rare gems or unseen multitudes?

description: The Transiting Exoplanet Survey Satellite (TESS) is optimized to search nearby M dwarf stars for transiting extrasolar planets, providing new opportunities to study planets orbiting low-mass stars. I seek to take advantage of these opportunities by conducting a survey of the coldest planets in these systems to constrain their occurrence rates and find targets for future mass and atmospheric characterization. To identify these planets in the TESS (and K2) data, I have designed a pipeline to detect both single- and multiply-transiting long-period planets. Based on a simulated planet catalog (Barclay et al., 2018), I anticipate 27 single-transiting and 32 multiply-transiting M dwarf planets with P>20 days from the TESS primary mission. To vet targets, I am creating a convolution neural network using the novel method of converting light curves into Gramian Angular Difference Fields to better recognize transit patterns. As nearly half of the anticipated long-period planets will be detected as single-transits, I look to the TESS extended mission to recover additional transits, which will facilitate finding true periods using ground based follow-up.

Kinetics of excitations on the Fermi arcs in underdoped cuprates at low temperature

description: The Fermi-liquid-like (FL) resistivity recently observed in clean HgBa2CuO4 below the pseudogap temperature was related to carriers at the nodal points on the Fermi surface [4]. We show that this necessitates important implications for the electronic spectrum of underdoped (UD) cuprates in whole. Photoemission experiments picture the spectrum as of metallic arcs separated from each other by regions with large energy gaps. We solved the kinetic equation in such model rigorously. The Fermi arcs carriers contribute to FL resistivity, if scattering between the opposite nodal points admits the Umklapp processes. The Hall coefficient defines the effective number of carriers on arcs and has the positive sign. For clean materials the expression is applicable only at weak magnetic fields. We discuss the Fermi arcs concept further in light of recent experimental findings and argue that the idea of reconstructed FS in UD cuprates is not consistent with the FL-like resistivity.

description: Calibration of the science instruments of the James Webb Space Telescope (JWST) is performed using standard stars. Their spectral types include white dwarfs, A, and G stars because they can be modeled to high accuracy. Selecting stars which are stable to within 2% allows accurate and reliable modeling [1,2]. Therefore, stars that vary in brightness because of pulsation, rotation, eclipses, flares or any other reason may need to be removed from the list of candidates. The Transiting Exoplanet Survey Satellite (TESS) has observed 34 candidate calibration stars for JWST. We examined the TESS light curves for evidence of periodic and transient phenomena and report on any detected variability. Using Lomb-Scargle periodograms, we searched for any significant periodic signals less than 15 days. We detected several variable stars in the set, and the peak-to-peak amplitudes for one were larger than 1%.

description: The goal of this paper is to investigate properties of clusterized nuclear matter which is believed to be present in crusts of neutron stars at subnuclear densities. It is assumed that the whole system can be represented by the set of Wigner-Seitz cells, each containing a nucleus and an electron background under the condition of electroneutrality. The nuclear structure calculations are performed within the relativistic mean-field model with the NL3 parametrization. The first set of calculations is performed assuming the constant electron background. The evolution of neutron and proton density distributions was systematically studied along isotopic chains until very neutron-rich system beyond the neutron dripline. Then we have replaced the uniform electron background with the realistic electron distributions, obtained within the Thomas-Fermi approximation in a self-consistent way with the proton distributions. Finally, we have investigated the evolution of the $β$-stability valley as well as neutron and proton driplines with the electron density.

description: There are thousands of previously known and newly identified eclipsing binaries observed almost continuously for nearly a year long during Year 2 of the TESS mission. These precise and unique data sets give us an opportunity to measure a significant amount of their eclipse times on a time-scale comparable to the usual outer orbital periods of compact hierarchical triple stellar systems (below 1-2 years). In our project, we obtain the light curves from TESS Full-Frame Images of more than 4,000 eclipsing binaries observed at least during 8 Sectors and determine their eclipse timing variations in order to search for the signals of third-body perturbations and/or light travel time effect caused by an unseen, more distant component. We present orbital solutions for the identified triple systems and statistical considerations will also be discussed.
