description: The elastic properties of the Zr$_{50}$Cu$_{40}$Ag$_{10}$ metallic alloy, such as the bulk modulus $B$, the shear modulus $G$, the Young's modulus $E$ and the Poisson's ratio $σ$, are investigated by molecular dynamics simulation in the temperature range $T=250-2000$ K and at an external pressure of $p = 1.0$ bar. It is shown that the liquid-glass transition is accompanied by a considerable increase in the shear modulus $G$ and the Young's modulus $E$ (by more than $50\%$). The temperature dependence of the Poisson's ratio exhibits a sharp fall from typical values for metals of approximately $0.32-0.33$ to low values (close to zero), which are characteristic for brittle bulk metallic glasses. Non-monotonic temperature dependence of the longitudinal and transverse sound velocity near the liquid-glass transition is also observed. The glass forming ability of the alloy is evaluated in terms of the fragility index $m$. As found, its value is $m\approx64$ for the Zr$_{50}$Cu$_{40}$Ag$_{10}$ metallic glass, that is in a good agreement with the experimental data for the Zr-Cu-based metallic glasses.

description: Σκοπός της εργασίας ήταν η μελέτη της σχολικής επίδοσης αγοριών και κοριτσιών που φοιτούν στο Γυμνάσιο. Αρχικά μελετήθηκαν οι παράγοντες που διαμορφώνουν τη σχολική επίδοση και σχετίζονται με το φύλο. Η κατασκευή της ταυτότητας του φύλου επιδρά στη διαμόρφωση του ανδρισμού (masculinity) και της θηλυκότητας (feminity) στη σχολική τάξη. Το κρυφό αναλυτικό πρόγραμμα, τα προβαλλόμενα έμφυλα στερεότυπα των σχολικών βιβλίων, οι έμφυλες στάσεις και προσδοκίες των εκπαιδευτικών διαμορφώνουν έμφυλα τη σχολική επίδοση αγοριών και κοριτσιών. Στη συνέχεια με μελέτη περίπτωσης διερευνήθηκε στην ελληνική πραγματικότητα η πιθανότητα διαφοροποιημένης σχολικής επίδοσης αγοριών και κοριτσιών που φοίτησαν στο γυμνάσιο από το σχολικό έτος 2002-2003 έως το σχολικό έτος 2007-2008. Χρησιμοποιήθηκε η ποσοτική μέθοδος και η στατιστική επεξεργασία των δεδομένων. Παρατηρήθηκε ότι από τάξη σε τάξη κατά τη διάρκεια φοίτησης αγοριών και κοριτσιών στο γυμνάσιο σημειώνονται χαμηλότερες επιδόσεις. Οι επιδόσεις των κοριτσιών και των αγοριών διαφοροποιούνται. Τα κορίτσια προάγονται ή απολύονται την εξεταστική περίοδο του Ιουνίου και τα αγόρια απορρίπτονται την περίοδο του Ιουνίου ή παραπέμπονται στην εξεταστική περίοδο του Σεπτεμβρίου. Τα κορίτσια σε σύγκριση με τα αγόρια έχουν καλύτερες επιδόσεις σε όλα τα μαθήματα.
description: Aim of this work was the study of boys’ and girls’ school attainment in the High school. Initially were studied the factors that shape the school attainment and are related with the gender. The configuration of gender identity affects in the constructive of masculinity and femininity in the school class. Gender stereotypes appear in the school books, in the attitudes and expectations of teachers and in the hidden curriculum and all the above shape the attainment of boys and girls. Afterwards studying this case was investigated the probability of boys’ and girls’ differentiated attainment. The quantitative method and the statistical processing of data were used. The degrees in all courses for six Greek school years were researched, from school year 2002-2003 until school year 2007-2008. It was detected that through the classes during the study of boys and girls in the high school are obtaining lower degrees. The girls’ and boys’ degrees are differentiated. The girls are mostly promoted or released in the examining period of June while the boys are often rejected in the same period or are repeating the exams in the period of September. The girls compared to the boys have better school attainment in the all courses.

description: We present a catalogue of galaxies in Abell 3653 from observations made with the 2dF spectrograph at the Anglo-Australian Telescope. Of the 391 objects observed, we find 111 are bone-fide members of Abell 3653. We show that the cluster has a velocity of cz = 32214 +/- 83 km/s (z=0.10738 +/- 0.00027), with a velocity dispersion typical of rich, massive clusters of sigma_{cz} = 880^{+66}_{-54}. We find that the cD galaxy has a peculiar velocity of 683 +/- 96 km/s in the cluster restframe - some 7sigma away from the mean cluster velocity, making it one of the largest and most significant peculiar velocities found for a cD galaxy to date. We investigate the cluster for signs of substructure, but do not find any significant groupings on any length scale. We consider the implications of our findings on cD formation theories.

description: We present the pressure-temperature phase diagram La$_5$Co$_2$Ge$_3$ up to $\sim$ 5\,GPa, which was constructed from magnetization, resistivity and specific heat measurements. At ambient pressure, La$_5$Co$_2$Ge$_3$ is an itinerant ferromagnet with a Curie temperature $T_\textrm C\sim$ 4\,K. Upon increasing pressure up to $\sim$ 1.7\,GPa, $T_\textrm C$ is suppressed down to $\sim$ 3\,K. Upon further increasing pressure, our results suggest that La$_5$Co$_2$Ge$_3$ enters a different low-temperature ground state. The corresponding transition temperature, $T^*$, has a nonmonotonic pressure dependence up to $\sim$ 5\,GPa. Our results demonstrate that the ferromagnetic quantum critical point in La$_5$Co$_2$Ge$_3$ is avoided by the appearance of a different, likely magnetically ordered state that has an antiferromagnetic component.

description: At the conceptual level, a model for ensuring information security of a cyber-physical system is proposed. For data protection the model represents a system invariant to any point of its connection in the architecture of cyber-physical system. Basic requirements to the information security model are formulated from the system positions. The structural model of information security of cyber-physical system is presented. Detection of unauthorized influence is determined by analyzing deviations of indirect signs of hardware functioning from their normative values.

description: The transition interface sampling (TIS) technique allows to overcome large free energy barriers within reasonable simulation time, which is impossible for straightforward molecular dynamics. Still, the method does not impose an artificial driving force, but it surmounts the timescale problem by an importance sampling of true dynamical pathways. Recently, it was shown that the efficiency of TIS to calculate reaction rates is less sensitive to the choice of reaction coordinate than those of the standard free energy based techniques. This could be an important advantage in complex systems for which a good reaction coordinate is usually very difficult to find. We explain the principles of this method and discuss some of the promising applications related to zeolite formation.

description: Introduction: Popliteal artery aneurysms (PAA) can be very challenging, especially in cases of very large PAAs, with a minimal number of case reports published in the literature.

Methods: This is a case report of a 68-year-old male patient with hypertension, hyperlipidemia, diabetes, and schizophrenia who was found to have a giant (10x8x6cm) partially thrombosed PAA, treated with interposition polytetrafluoroethylene (PTFE) graft via a posterior approach.

Results: Under general anesthesia, the patient was placed in a prone position, and an extended lazy "S" incision was made on the popliteal fossa. After obtaining proximal and distal exposure, the aneurysm sac was skeletonized, preserving the popliteal vein and the tibial nerve. After proximal and distal control was obtained, the patient was systemically heparinized, and the aneurysm sac was opened. Some genicular branches were ligated inside the aneurysm, and part of the aneurysm sac was excised. A 7 mm PTFE graft was used for reconstruction in an end-to-end fashion. Suction drains were placed in the popliteal space, and the fascia and skin were approximated. The patient was discharged home on the 2nd postoperative day on aspirin and statin with ultrasound surveillance. The patient has remained asymptomatic during follow-up with a patent graft.

Conclusions: Open surgical repair constitutes the gold standard of care for huge PAAs to prevent distal thromboembolic events and mass pressure effects from the aneurysm. Documentation of additional experience with open repair of huge PAAs would be beneficial and could help clinical decision-making.

description: We present 3.6, 4.5, 5.8, 8.0, 24, and 70 micron images of the Crab Nebula obtained with the Spitzer Space Telescope IRAC and MIPS cameras, Low- and High-resolution Spitzer IRS spectra of selected positions within the nebula, and a near-infrared ground-based image made in the light of [Fe II]1.644 micron. The 8.0 micron image, made with a bandpass that includes [Ar II]7.0 micron, resembles the general morphology of visible H-alpha and near-IR [Fe II] line emission, while the 3.6 and 4.5 micron images are dominated by continuum synchrotron emission. The 24 micron and 70 micron images show enhanced emission that may be due to line emission or the presence of a small amount of warm dust in the nebula on the order of less than 1% of a solar mass. The ratio of the 3.6 and 4.5 micron images reveals a spatial variation in the synchrotron power law index ranging from approximately 0.3 to 0.8 across the nebula. Combining this information with optical and X-ray synchrotron images, we derive a broadband spectrum that reflects the superposition of the flatter spectrum jet and torus with the steeper diffuse nebula, and suggestions of the expected pileup of relativistic electrons just before the exponential cutoff in the X-ray. The pulsar, and the associated equatorial toroid and polar jet structures seen in Chandra and HST images (Hester et al. 2002) can be identified in all of the IRAC images. We present the IR photometry of the pulsar. The forbidden lines identified in the high resolution IR spectra are all double due to Doppler shifts from the front and back of the expanding nebula and give an expansion velocity of approximately 1264 km/s.

description: The physical principles of causality and unitarity put strong constraints on the analytic structure of the flat-space S-matrix. In particular, these principles give rise to the Steinmann relations, which require that the double discontinuities of scattering amplitudes in partially-overlapping momentum channels vanish. Conversely, at cosmological scales, the imprint of causality and unitarity is in general less well understood---the wavefunction of the universe lives on the future space-like boundary, and has all time evolution integrated out. In the present work, we show how the flat-space Steinmann relations emerge from the structure of the wavefunction of the universe, and derive similar relations that apply to the wavefunction itself. This is done within the context of scalar toy models whose perturbative wavefunction has a first-principles definition in terms of cosmological polytopes. In particular, we use the fact that the scattering amplitude is encoded in the scattering facet of cosmological polytopes, and that cuts of the amplitude are encoded in the codimension-one boundaries of this facet. As we show, the flat-space Steinmann relations are thus implied by the non-existence of codimension-two boundaries at the intersection of the boundaries associated with pairs of partially-overlapping channels. Applying the same argument to the full cosmological polytope, we also derive Steinmann-type constraints that apply to the full wavefunction of the universe. These arguments show how the combinatorial properties of cosmological polytopes lead to the emergence of flat-space causality in the S-matrix, and provide new insights into the analytic structure of the wavefunction of the universe.

description: Η παρούσα εργασία διερευνά τις αντιθέσεις μεταξύ του κεφαλαίου και των κινημάτων με κέντρο τις μεταβολές στον αστικό ιστό και το δημόσιο χώρο κι επιχειρεί να αποδομήσει την ουσία των διαφορετικών συμφερόντων που εγγράφονται στην πολιτική διαπάλη των δύο πλευρών, με την αξιοποίηση του ειδικού παραδείγματος της περιοχής των Εξαρχείων στην εποχή του gentrification και των ιδιωτικοποιήσεων.
Η ανάλυση των αστικών πολιτικών που μετάλλαξαν τις πόλεις του δυτικού καπιταλισμού στην πορεία από τον 19ο ως τον 21ο αιώνα, επιχειρεί να συμβάλει στη βαθύτερη κατανόηση των δομικών χαρακτηριστικών του καπιταλιστικού συστήματος ως προς τη σύνδεση χωρικών πολιτικών και σχεδιασμού με την παραγωγή, την οικονομία και τις κοινωνικές σχέσεις, ενώ η διερεύνυση των αιτιών, των στόχων, του περιεχομένου και των μορφών που χαρακτηρίζουν τα κινήματα που αναδεικνύονται μέχρι και σήμερα ως προσπάθειες υπεράσπισης του δημόσιου χώρου, των πόλεων και ευρύτερα των συμφερόντων της εργατικής τάξης, είναι οι δύο κεντρικοί άξονες που θέτουν και την τεκμηριωμένη βάση για εξειδίκευση της μελέτης στο παράδειγμα των Εξαρχείων.
description: This paper is research about the contrasts between the capital and the social movements centered on the changes in the urban fabric and the public space and it attempts to deconstruct the essence of the different interests that are registered in the political struggle of the two sides, using the special example of the area of Exarchia in the era of gentrification and privatization.
The analysis of the urban policies that transformed the cities of western capitalism from the 19th to the 21st century, attempts to contribute to a deeper understanding of the structural features of the capitalist system in terms of the connection of spatial policies and planning with production, economy and social relations, while the investigation of the causes, objectives, content and forms that characterize the movements that emerge to this day as efforts to defend public space, cities and more broadly the interests of the working class, are the two central axes that set the basis for specialization of the research in the example of the Exarchia.

description: We present the results of an 80 ks Chandra ACIS-S observation of the double pulsar system J0737-3039. Furthermore, we report on spectral, spatial and timing analysis of the combined X-ray observations performed so far for this system. Fitting a total of ~1100 photons, we show that the X-ray spectrum of the J0737-3039 system is very soft, and not satisfactorily modeled by a simple blackbody or an atmospheric model. However, it is not possible yet to discriminate between a predominantly non-thermal and a predominantly thermal origin for the X-ray emission. Adopting a simple power-law emission model, the photon index (Gamma=3.7) and the implied conversion efficiency of the rotational energy of PSR J0737-3039A into X-ray emission (4.1x10^-4, for a distance to the source of 500 pc) are compatible with the X-ray photons being emitted in the magnetosphere of PSR J0737-3039A. This hypothesis is also supported by the absence of detectable X-ray orbital modulation (up to ~20%) or any X-ray nebular emission and it is in agreement with the high (~75%) X-ray pulsed fraction of PSR J0737-3039A. A two blackbody or a Comptonized blackbody model also reproduce the data, and the upper limit to the value of the hydrogen column density N_H <10^20 cm^-2, is in better agreement (with respect to the power-law model) with the Galactic N_H in that direction and at that distance. For the two blackbody model the implied emission radii and temperatures are also compatible with those seen in other recycled pulsars, calling for the bulk of the X-ray photons being originated from heated regions at the surface of pulsar A. On the other hand, in the Comptonized blackbody model, the electron temperature seems to be significantly smaller than in other similar objects.

description: The extraction of spectral features from a music clip is a computationally expensive task. As in order to extract accurate features, we need to process the clip for its whole length. This preprocessing task creates a large overhead and also makes the extraction process slower. We show how formatting a dataset in a certain way, can help make the process more efficient by eliminating the need for processing the clip for its whole duration, and still extract the features accurately. In addition, we discuss the possibility of defining set generic durations for analyzing a certain type of music clip while training. And in doing so we cut down the need of processing the clip duration to just 10% of the global average.

Κρίθηκε, αρχικά, αναγκαία η μελέτη της ιδανικής γι’ αυτούς Σχολικής Αγωγής, μιας και η Θρησκευτική Αγωγή εντάσσεται στην προσπάθεια του σχολείου για ψυχοσωματική τελείωση του παιδιού. Ο στόχος της Θρησκευτικής Αγωγής για τους δύο παιδαγωγούς δε διαφοροποιείται από τον προτεινόμενο στόχο των Προγραμμάτων Σπουδών της εποχής, που επιθυμεί το Θρησκευτικό Μάθημα να κινείται βάσει των αρχών του Ευσεβισμού-Ορθολογισμού, υπερτονίζοντας τη συγκινησιακή πλευρά της θρησκείας. Καμία καινοτομία δεν παρουσιάζεται, με εξαίρεση την αύξηση των σχολικών περιπάτων και την κατάργηση του σχολικού εγχειριδίου. Ωστόσο, ο Εκπαιδευτικός Διχασμός μεταβάλλει το στόχο του Μαθήματος: ο Δελμούζος επιθυμεί μια παιδεία α-κομματοποιημένη, με αναπόσπαστο το Θρησκευτικό Μάθημα από αυτή, ενώ ο Γληνός κινείται στον άξονα του Μαρξισμού, που καταργεί κάθε μορφή θρησκείας.
description: The present study aims to illuminate all those points that formate the frame of the visualized Religious Education for Delmouzos and Glinos. As Religious Education participates in the school’s attempt for child’s heart and hand completion, it was necessary at first to study the ideal Scholastic Education for both of them. The Religious Education’s target for the two men isn’t differentiated from the Essays Programs’ suggested target in this period, which desires the Religious lesson’s process according to the principles of Piety-Rationalism, by emphasizing the touching side of religion. None innovation is taking place, exempted the augmentation of outings and the abolition of school manual. But the Educational Disunion changes the lesson’s target. Delmouzos doesn’t desire an Education connected with Politics, by considering that Religious education is united with Scholastic Education. In a contrary way, Glinos is moving himself on the axis of Marxism, which abolishes every religion form.
Sign problem and MEM in lattice field theory with the $θ$ term

description: Lattice field theory with the $θ$ term suffers from the sign problem. The sign problem appears as flattening of the free energy. As an alternative to the conventional method, the Fourier transform method (FTM), we apply the maximum entropy method (MEM) to Monte Carlo data obtained using the CP$^3$ model with the $θ$ term. For data without flattening, we obtain the most probable images of the partition function ${\hat{\cal Z}}(θ)$ with rather small errors. The results are quantitatively close to the result obtained with the FTM. Motivated by this fact, we systematically investigate flattening in terms of the MEM. Obtained images ${\hat{\cal Z}}(θ)$ are consistent with the FTM for small values of $θ$, while the behavior of ${\hat{\cal Z}}(θ)$ depends strongly on the default model for large values of $θ$. This behavior of ${\hat{\cal Z}}(θ)$ reflects the flattening phenomenon.

description: We have investigated the characteristics of the currents in a pump-driven fermionic Mach-Zehnder interferometer. The system is implemented in a conductor in the quantum Hall regime, with the two interferometer arms enclosing an Aharonov-Bohm flux $Φ$. Two quantum point contacts with transparency modulated periodically in time drive the current and act as beam-splitters. The current has a flux dependent part $I^{(Φ)}$ as well as a flux independent part $I^{(0)}$. Both current parts show oscillations as a function of frequency on the two scales determined by the lengths of the interferometer arms. In the non-adiabatic, high frequency regime $I^{(Φ)}$ oscillates with a constant amplitude while the amplitude of the oscillations of $I^{(0)}$ increases linearly with frequency. The flux independent part $I^{(0)}$ is insensitive to temperature while the flux dependent part $I^{(Φ)}$ is exponentially suppressed with increasing temperature. We also find that for low amplitude, adiabatic pumping rectification effects are absent for semitransparent beam-splitters. Inelastic dephasing is introduced by coupling one of the interferometer arms to a voltage probe. For a long charge relaxation time of the voltage probe, giving a constant probe potential, $I^{(Φ)}$ and the part of $I^{(0)}$ flowing in the arm connected to the probe are suppressed with increased coupling to the probe. For a short relaxation time, with the potential of the probe adjusting instantaneously to give zero time dependent current at the probe, only $I^{(Φ)}$ is suppressed by the coupling to the probe.

description: Advanced electrical conductors that outperform copper and aluminum can revolutionize our lives, enabling billions of dollars in energy savings and facilitating a transition to an electric mobility future. Nanocarbons (carbon nanotubes and graphene) present a unique opportunity for developing advanced conductors for electrical power, communications, electronics, and electric machines for the aerospace, marine, and automotive industries. This paper compiles the major research progress in the field of advanced nanocarbon-based and metal-nanocarbon conductors. It also elucidates the competitiveness and implications of advanced conductors with respect to conventional ones and describes their materials science, properties, and characterization. Finally, several areas of future research for advanced electrical conductors are proposed.

description: Q fever is an ubiquitous zoonosis caused by Coxiella burnetii, an intracellular bacterium that can produce acute or chronic infections in humans. These forms are characterized by different evolution, serological profile and treatment that must be very long to achieve a cure in chronic forms. However, the serological profile for diagnosis and the real value of serology for predicting outcome are controversial, and management dilemmas for many patients with Q fever infection are continuously emerging. In this case report, we present a 20-year-old man from Nicaragua who worked as a farmer with a culture-negative infective endocarditis who presented with a mycotic aneurysm. The present report reviews the clinical presentation and diagnosis of Q fever IE.

description: We present data on long-range multiplicity correlations in ultra-relativistic heavy ion collisions at the top RHIC energy ($\sqrt{s_{NN}}$ = 200 GeV) from the STAR experiment. The data shows a long-range multiplicity correlation extending across a gap of 1.6 units in pseudorapidity. The data is over predicted by a multiparticle production model with hadronization of independent strings, or fusion of two color strings. This can be interpreted in terms of additional dynamical reduction in the number of particle sources.

description: Saint Kosmas Aitolos acted in a very difficult period for our nation, due to Turkish sovereignty. He fought for the spiritual rebirth of the nation, the preservation of the Greek language and the Orthodox faith. Throughout his struggle he remained faithful to the original, traditional ideas of the East and was not influenced by the irreligious ideas of the Enlightenment. Through his deeds he managed to stop Islamization and helped the enslaved Greeks to prosper, consolidate the Orthodox faith and educate themselves. Therefore, he was rightly recognized by our species as one of the leading lights, teachers, prophets and saints of our church.

Σε όλο τον αγώνα του παρέμεινε πιστός στις γνήσιες, παραδοσιακές ιδέες της ανατολής και δεν επηρεάστηκε από τις άθεες ιδέες του κινήματος του διαφωτισμού. Με το έργο του κατόρθωσε να σταματήσει τους εξισλαμισμούς, να βοηθήσει τους υπόδουλους Έλλη-νες να ορθοποδήσουν, να εδραιωθούν στην ορθόδοξη πίστη και να μορφωθούν. Δί-καια λοιπόν αναγνωρίστηκε από το γένος μας ως ένας από τους σημαντικότερους φω-τιστές, δασκάλους, προφήτες και αγίους της εκκλησίας μας.

description: This paper proposes to use keypoints as a self-supervision clue for learning depth map estimation from a collection of input images. As ground truth depth from real images is difficult to obtain, there are many unsupervised and self-supervised approaches to depth estimation that have been proposed. Most of these unsupervised approaches use depth map and ego-motion estimations to reproject the pixels from the current image into the adjacent image from the image collection. Depth and ego-motion estimations are evaluated based on pixel intensity differences between the correspondent original and reprojected pixels. Instead of reprojecting the individual pixels, we propose to first select image keypoints in both images and then reproject and compare the correspondent keypoints of the two images. The keypoints should describe the distinctive image features well. By learning a deep model with and without the keypoint extraction technique, we show that using the keypoints improve the depth estimation learning. We also propose some future directions for keypoint-guided learning of structure-from-motion problems.

description: Using projective superspace techniques, we consider 4D N = 2 and 5D N = 1 gauged supersymmetric nonlinear sigma-models for which the hyper-Kahler target space is (an open domain of the zero section of) the cotangent bundle of a real-analytic Kahler manifold. As in the 4D N = 1 case, one may gauge those holomorphic isometries of the base Kahler manifold (more precisely, their lifting to the cotangent bundle) which are generated by globally defined Killing potentials. In the U(1) case, by freezing the background vector (tropical) multiplet to a constant value of its gauge-invariant superfield strength, we demonstrate the generation of a chiral superpotential, upon elimination of the auxiliary superfields and dualisation of the complex linear multiplets into chiral ones. Our analysis uncovers a N = 2 superspace origin for the results recently obtained in hep-th/0601165.

description: We study the competition interface between two growing clusters in a growth model associated to last-passage percolation. When the initial unoccupied set is approximately a cone, we show that this interface has an asymptotic direction with probability 1. The behavior of this direction depends on the angle $θ$ of the cone: for $θ\geq180^{\circ}$, the direction is deterministic, while for $θ<180^{\circ}$, it is random, and its distribution can be given explicitly in certain cases. We also obtain partial results on the fluctuations of the interface around its asymptotic direction. The evolution of the competition interface in the growth model can be mapped onto the path of a second-class particle in the totally asymmetric simple exclusion process; from the existence of the limiting direction for the interface, we obtain a new and rather natural proof of the strong law of large numbers (with perhaps a random limit) for the position of the second-class particle at large times.

description: We present a theory for the onset of spin density wave order in the superconducting ground state of the cuprates. We compute the scaling dimensions of allowed perturbations of a `relativistic' fixed point with O(4)xO(3) symmetry, including those associated with the fermionic nodal Bogoliubov quasiparticles. Analyses of up to six loops show that all perturbations with square lattice symmetry are likely irrelevant. We demonstrate that the fermion spectral functions are primarily damped by the coupling to fluctuations of a composite field with Ising nematic order. We also discuss the influence of quenched disorder.

description: We present a new method for the calculation of black hole perturbations induced by extended sources in which the solution of the nonlinear hydrodynamics equations is coupled to a perturbative method based on Regge-Wheeler/Zerilli and Bardeen-Press-Teukolsky equations when these are solved in the frequency domain. In contrast to alternative methods in the time domain which may be unstable for rotating black-hole spacetimes, this approach is expected to be stable as long as an accurate evolution of the matter sources is possible. Hence, it could be used under generic conditions and also with sources coming from three-dimensional numerical relativity codes. As an application of this method we compute the gravitational radiation from an oscillating high-density torus orbiting around a Schwarzschild black hole and show that our method is remarkably accurate, capturing both the basic quadrupolar emission of the torus and the excited emission of the black hole.

description: Local examples of jet-induced star formation lend valuable insight into its significance in galaxy evolution and can provide important observational constraints for theoretical models of positive feedback. Using optical integral field spectroscopy, we present an analysis of the ISM conditions in Minkowski's Object ($z = 0.0189$), a peculiar star-forming dwarf galaxy located in the path of a radio jet from the galaxy NGC 541. Full spectral fitting with PPXF indicates that Minkowski's Object primarily consists of a young stellar population $\sim 10$ Myr old, confirming that the bulk of the object's stellar mass formed during a recent jet interaction. Minkowski's Object exhibits line ratios largely consistent with star formation, although there is evidence for a low level ($\lesssim 15$ per cent) of contamination from a non-stellar ionising source. Strong-line diagnostics reveal a significant variation in the gas-phase metallicity within the object, with $\log\left( \rm O / H \right) + 12$ varying by $\sim 0.5$ dex, which cannot be explained by in-situ star formation, an enriched outflow from the jet, or enrichment of gas in the stellar bridge between NGC 541 and NGC 545/547. We hypothesise that Minkowski's Object either (a) was formed as a result of jet-induced star formation in pre-existing gas clumps in the stellar bridge, or (b) is a gas-rich dwarf galaxy that is experiencing an elevation in its star formation rate due to a jet interaction, and will eventually redden and fade, becoming an ultra-diffuse galaxy as it is processed by the cluster.
