description: Aims. The project aims to understand better the role of wide brown dwarf companions on planetary systems. Methods. We obtained high-resolution spectra of six bright stars with co-moving wide substellar companions with the SONG, CARMENES, and STELLA high-resolution spectrographs. We used these spectra to derive radial velocities together with a complete set of stellar physical parameters. We then investigated radial velocities signals and discussed the fraction of planets in such systems. We also re-analyzed the ages of our targets, which were used to derive the physical parameters of wide brown dwarf companions. Finally, a compilation of systems with known planets from the literature is considered along with our sample to search for possible peculiarities in their parameter distributions. Results. Based on the derived ages of six observed systems, we re-computed the masses of the wide companions, confirming their substellar nature. We confirmed planets in the HD 3651 and HIP 70849 systems and found a new planetary candidate in the HD 46588 system. In our survey, which is sensitive mostly to Neptune-mass planets at short periods of a few days and Saturn-mass planets at longer periods of hundreds of days, we derived a frequency of planets orbiting stars with wide brown dwarf companions below 70% with the uncertainties included. Comparing the parameter distributions of our sample with single stars, we observe the enhancement of planets with short periods below six days in systems with a wide stellar companion. Finally, planets in systems with wide BD companions follow their own eccentricity distribution with a maximum at $\sim0.65$ and have periods larger than 40 days, masses larger than $0.1\,M_J$, and eccentricities larger than 0.4.

description: Sarà sicuramente capitato a tutti di non riuscire ad imparare un numero, una frase, una canzone e di non ricordare che cosa ci fosse scritto in un certo paragrafo nel libro di storia. L’apprendimento è qualcosa di decisamente complicato che implica l’attivazione di tanti processi. Apprendere un concetto significa saper comprenderlo, memorizzarlo, comunicarlo e successivamente anche applicarlo nella realtà. Quando il professore o la professoressa ti interroga non vuole solo torturarti, ma cerca di capire e valutare se hai o no assimilato quello che è stato spiegato. Ognuno di noi ha diversi modi e metodi per imparare. Se ci pensi, confrontandoti con i tuoi compagni, qualcuno preferisce ascoltare, qualche altro prendere appunti, altri ancora invece disegnare mentre il docente spiega. Inoltre, devi sapere che il processo di apprendimento segue uno sviluppo naturale. A mano a mano che cresciamo automatizziamo delle capacità. Per esempio, più leggiamo e scriviamo e più diventeremo veloci nella lettura e nella scrittura. Alcune persone però faticano a sviluppare questi automatismi e a consolidare le proprie conoscenze. Questo si verifica quando si presenta un disturbo specifico di apprendimento (DSA).

description: In this paper, we describe a mathematical model and a numerical simulation method for the condenser component of a novel two-phase thermosyphon cooling system for power electronics applications. The condenser consists of a set of roll-bonded vertically mounted fins among which air flows by either natural or forced convection. In order to deepen the understanding of the mechanisms that determine the performance of the condenser and to facilitate the further optimization of its industrial design, a multiscale approach is developed to reduce as much as possible the complexity of the simulation code while maintaining reasonable predictive accuracy. To this end, heat diffusion in the fins and its convective transport in air are modeled as 2D processes while the flow of the two-phase coolant within the fins is modeled as a 1D network of pipes. For the numerical solution of the resulting equations, a Dual Mixed-Finite Volume scheme with Exponential Fitting stabilization is used for 2D heat diffusion and convection while a Primal Mixed Finite Element discretization method with upwind stabilization is used for the 1D coolant flow. The mathematical model and the numerical method are validated through extensive simulations of realistic device structures which prove to be in excellent agreement with available experimental data.

description: The branching fraction of the $B_s\to K^0\bar K^0$ decay has been recently measured by the LHCb and Belle experiments. We study the consistency of the measured value with three relations to other decay rates and CP asymmetries which follow from the Standard Model, and from the approximate flavor $SU(3)$ symmetry of the strong interactions. We find that each of these relations is violated at a level of above $3σ$. We argue that various subleading effects -- rescattering, electroweak penguins and $SU(3)$ breaking -- if larger than theoretically expected, can account for some of these puzzles, but not for all of them simultaneously.

description: We present timing solutions for 12 pulsars discovered in the Green Bank North Celestial Cap (GBNCC) 350 MHz pulsar survey, including six millisecond pulsars (MSPs), a double neutron star (DNS) system, and a pulsar orbiting a massive white dwarf companion. Timing solutions presented here include 350 and 820 MHz Green Bank Telescope data from initial confirmation and follow-up as well as a dedicated timing campaign spanning one year. PSR J1122$-$3546 is an isolated MSP, PSRs J1221$-$0633 and J1317$-$0157 are MSPs in black widow systems and regularly exhibit eclipses, and PSRs J2022+2534 and J2039$-$3616 are MSPs that can be timed with high precision and have been included in pulsar timing array experiments seeking to detect low-frequency gravitational waves. PSRs J1221$-$0633 and J2039$-$3616 have Fermi Large Area Telescope $γ$-ray counterparts and also exhibit significant $γ$-ray pulsations. We measure proper motion for three of the MSPs in this sample and estimate their space velocities, which are typical compared to those of other MSPs. We have detected the advance of periastron for PSR J1018$-$1523 and therefore measure the total mass of the double neutron star system, $m_{\rm tot}=2.3\pm0.3$ M$_{\odot}$. Long-term pulsar timing with data spanning more than one year is critical for classifying recycled pulsars, carrying out detailed astrometry studies, and shedding light on the wealth of information in these systems post-discovery.

title: Anton P. Čechovs Methoden der Desorientierung in seinen späten Erzählungen und Dramen
Creators: name: Entenfellner, Pia-Maria
Year: 2023

description: Anton P. Čechovs Werke werden bis heute sowohl in Russland als auch im Ausland vielfach rezipiert, analysiert und aufgeführt. Das liegt mitunter daran, dass vor allem seine Spätwerke verschiedenste Interpretationsmöglichkeiten bieten, da wesentliche Teile des Textes bewusst ausgelassen und widersprüchliche Andeutungen gemacht werden. Auf diese Weise wirft Čechov Fragen auf, welche seine LeserInnen desorientieren und zur aktiven Rezeption der Texte ‚appellieren‘. Ziel dieser Arbeit ist es darum, mithilfe von Isers Konzept der ‚Leerstelle‘ die Methoden der Desorientierung in Čechovs späten Erzählungen und Dramen zu vergleichen. Dazu wird folgende Forschungsfrage gestellt: ‚Welche Methoden der Desorientierung wendet Čechov in seinen späten Erzählungen im Vergleich zu seinen späten Dramen an?‘ Um diese zu beantworten, wurde eine Analyse der ‚Leerstellen‘ im Hinblick auf die Handlungs- und Kommunikationsebene sowie die Erzähl- und Figurenperspektive an Beispielen beider Genres durchgeführt. Dabei wurde die Hypothese teilweise bestätigt, dass in den späten Dramen ein erhöhtes Maß an ‚Leerstellen‘ zu finden ist im Vergleich zu den späten Erzählungen, da mit jeder zusätzlichen Figur neue ‚Leerstellen‘ entstehen durch deren undurchsichtige Motive und heimliche Sehnsüchte. Die Hypothese wurde allerdings nur teilweise bestätigt, da Čechovs Erzählungen in anderen Bereichen wie etwa den scheinbaren Erkenntnismomenten oder dem offenen Schluss eine ebenso desorientierende Wirkung entfalten wie die späten Dramen. Schließlich wurde auch gezeigt, dass die ‚Leerstellen‘ eine wesentliche Rolle spielten in der Entstehung von Čechovs ‚prosaischem‘ Drama, welches den Weg für das moderne Theater ebnete. Alles in allem leistet diese Arbeit einen Beitrag zum Verständnis von Čechovs Entwicklung als ‚Fragensteller‘ und gibt Hinweise darauf, warum seine Werke einen so tiefen Eindruck in den RezipientInnen hinterlassen.

description: In der vorliegenden Masterarbeit erfolgt eine kulturwissenschaftlich kontextualisierte linguistische Analyse der Umbenennung von Wiener Straßennamen. Ausgehend von einer soziolinguistischen Perspektive auf die Funktion der Sprache im urbanen Raum, finden zeitgeschichtliche und soziologische Modellierungen des öffentlichen, urbanen und sozialen Raumes eine entsprechende Berücksichtigung. Denn Orte können nicht zuletzt als Träger der Erinnerung einer Gesellschaft an die Vergangenheit gesehen werden. So ist auch der öffentliche Raum in der Stadt Wien stark von sogenannten „Erinnerungsorten“ geprägt. Straßennamen – und hier vor allem personenbezogene Straßennamen – übermitteln als schriftliche Denkmäler einen Teil der Geschichte einer Gesellschaft, die stets kritisch reflektiert werden sollte. Den theoretischen Rahmen dieser Masterarbeit bilden namentheoretische und soziolinguistische Ansätze, kulturwissenschaftliche Theorien zum „Kulturellen Gedächtnis“ sowie soziologisch-philosophische Konzepte des sozialen Raumes. Im empirischen Teil der Arbeit erfolgt einerseits eine Analyse der im Bericht einer Historiker:innen-Kommission (vgl. Rathkolb [u. a.] 2013) unter „Fälle mit intensivem Diskussionsbedarf“ zusammengefassten Straßennamen nach sozioonomastischen Gesichtspunkten. Auf Basis der anschließenden inhaltlich strukturierenden qualitativen Inhaltsanalyse (nach Kuckartz / Rädiker 2022) von ausgewählten einschlägigen, online verfügbaren Medienberichten werden die Diskurse um Umbenennungen historisch belasteter Straßennamen in Wien untersucht.
description: This master thesis aims to explore a linguistic analysis of the renaming of Viennese street names contextualized by cultural studies. Based on the linguistic perspective of the function of language in an urban setting, contemporary historical and sociological modeling of public, urban and social space plays an important role, since places can be seen as carriers of memories of a society's past. Therefore, the public space in the city of Vienna is also characterized by "places of memory". In addition, street names - especially street names being directly linked to people - transmit a part of the history which should always be reflected critically. The theoretical framework of this master thesis includes name-theoretical, sociolinguistic approaches and cultural-scientific theories of "cultural memory". In the empirical part of the work, street names summarized in a report by a commission of historians (cf. Rathkolb [et al.] 2013) labelled as "cases with intensive need for discussion" are analyzed by means of socio-onomastic aspects. Subsequently, the renaming discussions of historically controversial street names in Vienna are examined by conducting a qualitative discourse-linguistic analysis of selected media reports.

description: The morphological classification of galaxies is considered a relevant issue and can be approached from different points of view. The increasing growth in the size and accuracy of astronomical data sets brings with it the need for the use of automatic methods to perform these classifications. The aim of this work is to propose and evaluate a method for automatic unsupervised classification of kinematic morphologies of galaxies that yields a meaningful clustering and captures the variations of the fundamental properties of galaxies. We obtain kinematic maps for a sample of 2064 galaxies from the largest simulation of the EAGLE project that mimics integral field spectroscopy (IFS) images. These maps are the input of a dimensionality reduction algorithm followed by a clustering algorithm. We analyse the variation of physical and observational parameters among the clusters obtained from the application of this procedure to different inputs. The inputs studied in this paper are (a) line-of-sight velocity maps for the whole sample of galaxies observed at fixed inclinations, (b) line-of-sight velocity, dispersion, and flux maps together for the whole sample of galaxies observed at fixed inclinations, (c) line-of-sight velocity, dispersion, and flux maps together for two separate subsamples of edge-on galaxies with similar amount of rotation, and (d) line-of-sight velocity, dispersion, and flux maps together for galaxies from different observation angles mixed. The application of the method to solely line-of-sight velocity maps achieves a clear division between slow rotators (SRs) and fast rotators (FRs) and can differentiate rotation orientation. By adding the dispersion and flux information at the input, low rotation edge-on galaxies are separated according to their shapes. Abridged.

description: We suggest a new Bayesian analysis using disjunct M-R constraints for extracting probability measures for cold, dense matter equations of state. One of the key issues of such an analysis is the question of a deconfinement transition in compact stars and whether it proceeds as a crossover or rather as a first order transition. The latter question is relevant for the possible existence of a critical endpoint in the QCD phase diagram under scrutiny in present and upcoming heavy-ion collision experiments.

description: Recent experimental advances in the field of cold-atom cavity QED provide a powerful tool for exploring non-equilibrium correlated quantum phenomena beyond conventional condensed-matter scenarios. We present the dynamical phase diagram of a driven Bose-Einstein condensate coupled with the light field of a cavity, with a transverse driving field red-detuned from atomic resonance. We identify regions in parameter space showing dynamical instabilities in the form of limit cycles, which evolve into chaotic behavior in the strong driving limit. Such limit cycles originate from the interplay between cavity dissipation and atom-induced resonance frequency shift, which modifies the phase of cavity mode and gives excessive negative feedback on the atomic density modulation, leading to instabilities of the superradiant scattering. We find interesting merging of the limit cycles related by a $Z_2$ symmetry, and identify a new type of limit cycle formed by purely atomic excitations. The effects of quantum fluctuations and atomic interactions are also investigated.

description: The fine spectral structures of solar radio type-I bursts were observed by the solar radio telescope AMATERAS. The spectral characteristics, such as the peak flux, duration, and bandwidth, of the individual burst elements were satisfactorily detected by the highly resolved spectral data of AMATEAS with the burst detection algorithm that is improved in this study. The peak flux of the type-I bursts followed a power-law distribution with a spectral index of 2.9-3.3, whereas their duration and bandwidth were distributed more exponentially. There were almost no correlations between the peak flux, duration, and bandwidth. That means there were no similarity shapes in the burst spectral structures. We defined the growth rate of a burst as the ratio between its peak flux and duration. There was a strong correlation between the growth rate and peak flux. These results suggest that the free energy of type-I bursts that is originally generated by non-thermal electrons is modulated in the subsequent stages of the generation of non-thermal electrons, such as plasma wave generation, radio wave emissions, and propagation. The variation of the time scale of the growth rate is significantly larger than that of the coronal environments. These results can be explained by the situation that the source region may have the inhomogeneity of an ambient plasma environment, such as the boundary of open and closed field lines, and the superposition of entire emitted bursts was observed by the spectrometer.

description: Multipartite entanglement refers to the simultaneous entanglement between multiple subsystems of a many-body quantum system. While multipartite entanglement can be difficult to quantify analytically, it is known that it can be witnessed through the Quantum Fisher information (QFI), a quantity that can also be related to dynamical Kubo response functions. In this work, we first show that the finite temperature QFI can generally be expressed in terms of a static structure factor of the system, plus a correction that vanishes as $T\rightarrow 0$. We argue that this implies that the static structure factor witnesses multipartite entanglement near quantum critical points at temperatures below a characteristic energy scale that is determined by universal properties, up to a non-universal amplitude. Therefore, in systems with a known static structure factor, we can deduce finite temperature scaling of multipartite entanglement and low temperature entanglement depth without knowledge of the full dynamical response function of the system. This is particularly useful to study 1D quantum critical systems in which sub-power-law divergences can dominate entanglement growth, where the conventional scaling theory of the QFI breaks down. The 1D spin-$\frac{1}{2}$ antiferromagnetic Heisenberg model is an important example of such a system, and we show that multipartite entanglement in the Heisenberg chain diverges non-trivially as $\sim \log(1/T)^{3/2}$. We verify these predictions with calculations of the QFI using conformal field theory and matrix product state simulations. Finally we discuss the implications of our results for experiments to probe entanglement in quantum materials, comparing to neutron scattering data in KCuF$_3$, a material well-described by the Heisenberg chain.

However, only a subset of cancer patients responds to ICB therapies causing an urgent need for novel approaches to better select patients who may benefit from immunotherapy. Here, we used metastatic ccRCC samples obtained before ICB treatment and performed cell deconvolution analysis to investigate novel biomarkers of ICB treatment response.

description: Context. Cassiopeia A is one of the most extensively studied supernova remnants (SNRs) in our Galaxy. The analysis of its spectral features with the help of low frequency observations plays an important role for understanding the evolution of the radio source through the propagation of synchrotron emission to observers through the SNR environment and the interstellar medium. Aims. In this paper we present measurements of the integrated spectrum of Cas A to characterize the properties of free-free absorption towards this SNR. We also add new measurements to track its slowly evolving and decreasing integrated flux density. Methods. We use the Giant Ukrainian radio telescope (GURT) for measuring the continuum spectrum of Cassiopeia A within the frequency range of 16-72 MHz. The radio flux density of Cassiopeia A relative to the reference source of the radio galaxy Cygnus A has been measured on May-October, 2019 with two subarrays of the GURT, used as a two-element correlation interferometer. Results. We determine magnitudes of emission measure, electron temperature and an average number of charges of the ions for both internal and external absorbing ionized gas towards in Cassiopeia A. Generally, their values are close to the ones suggested by Arias et al. (2018), although for some there are slight differences. In the absence of clumping we find the unshocked ejecta of M = 2.61 solar mass at the electron density of 15.3 cm^-3 has a gas temperature of T=100 K. If the clumping factor is 0.67, then the unshocked ejecta of 0.96 solar mass the electron density of 18.7 cm^-3. Conclusions. The integrated flux density spectrum of Cassiopeia A obtained with the GURT interferometric observations is consistent with the theoretical model within measurement errors and also reasonably consistent with other recent results in the literature.

description: The aim of this study was to investigate the effects of fructo-oligosaccharide (FOS) supplementation intake of Taiping chickens (Gallus gallus domesticus) and its stimulating effects on ileum. 120 healthy chickens were randomly divided into two groups; control group (CT) and fructo-oligosaccharides group (FOS). At the 60th day of age, ileum mucosa of three chickens per group were collected and performed transcriptome profiling of Taiping chicken ileum mucosa using the Hiseq™ 2500 sequencing platform. Compared with CT group, 50 genes were differentially expressed in the FOS group. Ten of the differently expressed genes were further validated by RT-qPCR. In addition, gene ontology and Kyoto encyclopedia of genes and genomes analyses revealed that these differentially expressed genes were mainly enriched to drug metabolism-cytochrome P450, metabolism of xenobiotics by cytochrome P450, retinol metabolism, fat digestion and absorption, herpes simplex infection and valine, leucine and isoleucine biosynthesis. The results of this study provided the help to our understanding application of fructo-oligosaccharides in indigenous chicken production and provide a theoretical basis for the genetic development of indigenous chickens.
Spectral function of the $η'$ meson in nuclear medium based on phenomenological models

description: The in-medium modification of the spectral function of the $η'$ meson with and without the spatial momentum is studied with the $Tρ$ approximation by employing two phenomenological models for the $η'N$ scattering; one is called coupled channels model and the other the $N(1895)$-dominance model. In the former model, the $η'N$ scattering amplitude is calculated in the unitarized coupled-channel approach involving the $η'N$ channel, while in the latter model the $η'N$ scattering process is dominated by the $N(1895)$ resonance with the spin and parity $J^P=1/2^-$. In the \com{coupled channels model}, one single peak of the in-medium $η'$ mode appears in the spectral function and the peak position shifts to higher energies along with the increase of the nuclear density reflecting the repulsive $η'N$ scattering length of the unitarized coupled-channel amplitude. On the other hand, two branches related to the $η'$ and $N(1895)$-hole modes appear in the $N(1895)$-dominance model. In both models, the shift of the peak position and the width in the spectral function are a few tens of MeV at the normal nuclear density for the $η'$ meson at rest in the nuclear medium. Once the spatial momentum is turned on, the peak positions in the spectral function approach the energies without the nuclear medium effect. Particularly, in the $N(1895)$-dominance model, the peak strength of the $N(1895)$-hole mode gets smaller with the finite momentum and the spectral function comes to have one single peak.

description: Whether or not space-time is fundamentally discrete is of central importance for the development of the theory of quantum gravity. If the fundamental description of space-time is discrete, typically represented in terms of a graph or network, then the apparent smoothness of geometry on large scales should be imperfect -- it should have defects. Here, we review a model for space-time defects and summarize the constraints on the prevalence of these defects that can be derived from observation.

description: Wild yak (Bos mutus) is a vulnerable bovine species on the Qinghai-Tibetan Plateau. So far, most studies on the molecular genetic diversity of wild yak have focused on autosomal and mtDNA variations based on the small number of samples. In this study, we analyzed 84 D-loop and 24 whole mitogenome sequences of wild yak to further comprehensively explore its maternal genetic diversity and lineage composition. Meanwhile, using six yak Y-specific polymorphic markers (i.e., SRY4, USP9Y, UTY19, AMELY3, OFD1Y10 and INRA189), we assessed the paternal genetic diversity and lineage composition based on eight wild yak. Our results showed that wild yak exhibited abundant maternal genetic diversity with haplotype diversities of 0.9621 ± 0.0078 and 0.9928 ± 0.0144 in the D-loop and whole mitogenome sequences, respectively. Maternal phylogenetic analysis of wild yak uncovered three defined lineages (mt-I, mt-II and mt-III). Similarly, profuse paternal genetic diversity was observed in wild yak with Y-haplotype diversity at 0.8214 ± 0.1007. Two Y-haplogroups (Y1 and Y2) and four Y-haplotypes (yH1-yH4) were identified in paternal phylogenetic analysis, indicating wild yak to be of two paternal lineages. The present study of genetic diversity and lineage composition of wild yak would provide useful information for the genetic resource conservation and utilization of this vulnerable wild species.

A Photometric Survey of Globular Cluster Systems in Brightest Cluster Galaxies
Creators: name: Harris, William E.
Publisher: name: arXiv
Year: 2022
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Hubble Space Telescope imaging for 26 giant early-type galaxies, all drawn from the MAST archive, is used to carry out photometry of their surrounding globular cluster (GC) systems. Most of these targets are Brightest Cluster Galaxies (BCGs) and their distances range from 24 to 210 Mpc. The catalogs of photometry, completed with DOLPHOT, are publicly available. The GC color indices are converted to [Fe/H] through a combination of 12-Gyr SSP (Single Stellar Population) models and direct spectroscopic calibration of the fiducial color index (F475W-F850LP). All the resulting metallicity distribution functions (MDFs) can be accurately matched by bimodal Gaussian functions. The GC systems in all the galaxies also exhibit shallow metallicity gradients with projected galactocentric distance that average $Z \sim R_{gc}^{-0.3}$. Several parameters of the MDFs including the means, dispersions, and blue/red fractions are summarized. Perhaps the most interesting new result is the trend of blue/red GC fraction with galaxy mass, which connects with predictions from recent simulations of GC formation within hierarchical assembly of large galaxies. The observed trend reveals two major transition stages: for low-mass galaxies, the metal-rich (red) GC fraction $f(red)$ increases steadily with galaxy mass, until halo mass $M_h \simeq 3 \times 10^{12} M_{\odot}$. Above this point, more than half the metal-poor (blue) GCs come from accreted satellites and $f(red)$ starts declining. But above a still higher transition point near $M_h \simeq 10^{14} M_{\odot}$, the data hint that $f(red)$ may start to increase again because the metal-rich GCs also become dominated by accreted systems.

Parallel Flow-Based Hypergraph Partitioning

Publisher: name: Schloss Dagstuhl - Leibniz-Zentrum für Informatik GmbH (LZI)
Year: 2022

description: We present a shared-memory parallelization of flow-based refinement, which is considered the most powerful iterative improvement technique for hypergraph partitioning at the moment. Flow-based refinement works on bipartitions, so current sequential partitioners schedule it on different block pairs to improve k-way partitions. We investigate two different sources of parallelism: a parallel scheduling scheme and a parallel maximum flow algorithm based on the well-known push-relabel algorithm. In addition to thoroughly engineered implementations, we propose several optimizations that substantially accelerate the algorithm in practice, enabling the use on extremely large hypergraphs (up to 1 billion pins). We integrate our approach in the state-of-the-art parallel multilevel framework Mt-KaHyPar and conduct extensive experiments on a benchmark set of more than 500 real-world hypergraphs, to show that the partition quality of our code is on par with the highest quality sequential code (KaHyPar), while being an order of magnitude faster with 10 threads.

description: We extend the study of hadron yield correlation in combination models in a recent publication to baryon-anti-baryon flavor correlations in heavy ion collisions. We show that the universal behaviors of the anti-baryon to baryon yield ratios as functions of that of $K^-$ to $K^+$ are naturally explained. We study also the "mixed ratios" and propose other measurements that might be sensitive to the hadronization mechanism.

description: Context. Star-forming regions are excellent benchmarks for testing and validating theories of star formation and stellar evolution. The Perseus star-forming region being one of the youngest (<10 Myr), closest (280-320 pc), and most studied in the literature, is a fundamental benchmark. Aims. We aim to study the membership, phase-space structure, mass, and energy (kinetic plus potential) distribution of the Perseus star-forming region using public catalogues (Gaia, APOGEE, 2MASS, PanSTARRS). Methods. We use Bayesian methodologies accounting for extinction to identify the Perseus physical groups in the phase-space, retrieve their candidate members, derive their properties (age, mass, 3D positions, 3D velocities, and energy), and attempt to reconstruct their origin. Results. We identify 1052 candidate members in seven physical groups (one of them new) with ages between 3 and 10 Myr, dynamical super-virial states, and large fractions of energetically unbound stars. Their mass distributions are broadly compatible with that of Chabrier for masses >0.1 $M_\odot$ and do not show hints of over-abundance of low-mass stars in NGC1333 with respect to IC348. These groups' ages, spatial structure, and kinematics are compatible with at least three generations of stars. Future work is still needed to clarify if the formation of the youngest was triggered by the oldest. Conclusions. The exquisite Gaia data complemented with public archives and mined with comprehensive Bayesian methodologies allow us to identify 31% more members than in previous studies, discover a new physical group (Gorgophone: 7 Myr, 191 members, and 145 $M_\odot$), and confirm that the spatial, kinematic, and energy distributions of these groups support the hierarchical star-formation scenario.

Effects of Mass Varying Neutrinos on Cosmological Parameters as determined from the Cosmic Microwave Background

description: In models with a light scalar field (the `acceleron') coupled to neutrinos, neutrino masses depend on neutrino density. The resulting coupled system of mass varying neutrinos (MaVaNs) and the acceleron can act as a negative pressure fluid and is a candidate for dark energy \cite{Fardon:2003eh} . MaVaNs also allow for higher $Σ$m$_ν$ than terrestrial bounds, giving late forming warm dark matter. In this paper we study the effect of increasing neutrino mass on the CMB spectrum, implementing MaVaNs cosmology using CMBEASY. We find that the CMB spectrum is only affected at very low multipoles. Cosmic variance allows for significant warm dark matter at late times. This implies that in MaVaNs cosmology $σ_8$ as determined by the CMB may not be a good determinant of structure evolution at late times, potentially reducing the tension between $σ$$_{8}$ as reported by Planck Collaboration \cite{PlanckSZ:2013} without increasing the tension in the Planck determined value of Hubble's constant. In addition, in MaVaNs theories, CMB data do not necessarily constrain possible neutrino mass results in terrestrial experiments.

description: We consider a non-Hermitian medium with a gain and loss symmetric, exponentially damped potential distribution to demonstrate different scattering features analytically. The condition for critical coupling (CC) for unidirectional wave and coherent perfect absorption (CPA) for bidirectional waves are obtained analytically for this system. The energy points at which total absorption occurs are shown to be the spectral singular points for the time reversed system. The possible energies at which CC occurs for left and right incidence are different. We further obtain periodic intervals with increasing periodicity of energy for CC and CPA to occur in this system.
