Implications from the Velocity Profile of the M87 Jet: A Possibility of a Slowly Rotating Black Hole Magnetosphere

Published: November 2022

Abstract
Motivated by the measured velocity profile of the M87 jet using the Korean very-long-baseline interferometry (VLBI) network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA) by Park et al. indicating that the starting position of the jet acceleration is farther from the central engine of the jet than predicted in general relativistic magnetohydrodynamic simulations, we explore how to mitigate the apparent discrepancy between the simulations and the KaVA observation. We use a semi-analytic jet model proposed by Tomimatsu & Takahashi consistently solving the transmagnetic field structure but neglecting any dissipation effects. By comparing the jet model with the observed M87 jet velocity profile, we find that the model can reproduce the logarithmic feature of the velocity profile and can fit the observed data when choosing c/(100r

F
) makes a light-cylinder radius (r
lc) larger, and it consequently pushes out a location of a starting point of the jet acceleration. Using the estimated Ω
F
we further estimate the magnetic field strength on the event horizon scale in M87 by assuming Blandford–Znajek process is in action. The corresponding magnetic flux threading the event horizon of M87 is in good agreement with a magnetically arrested disk regime.
Dynamical Disruption Timescales and Chaotic Behavior of Hierarchical Triple Systems
Authors: Hayashi 林 Toshinori 利憲 , Trani Alessandro A. , Suto 須藤 Yasushi 靖 
Published: November 2022

Abstract
We examine the stability of hierarchical triple systems using direct N-body simulations without adopting a secular perturbation assumption. We estimate their disruption timescales in addition to the mere stable/unstable criterion, with particular attention to the mutual inclination between the inner and outer orbits. First, we improve the fit to the dynamical stability criterion by Mardling & Aarseth widely adopted in the previous literature. Especially, we find that that the stability boundary is very sensitive to the mutual inclination; coplanar retrograde triples and orthogonal triples are much more stable and unstable, respectively, than coplanar prograde triples. Next, we estimate the disruption timescales of triples satisfying the stability condition up to 109 times the inner orbital period. The timescales follow the scaling predicted by Mushkin & Katz, especially at high e
out where their random walk model is most valid. We obtain an improved empirical fit to the disruption timescales, which indicates that the coplanar retrograde triples are significantly more stable than the previous prediction. We furthermore find that the dependence on the mutual inclination can be explained by the energy transfer model based on a parabolic encounter approximation. We also show that the disruption timescales of triples are highly sensitive to tiny changes of the initial parameters, reflecting the genuine chaotic nature of the dynamics of those systems.
Analysis of Thermal Emissions of Exoplanets with Axially Symmetric Temperature Gradients
Authors: Carter Jennifer L. 
Published: November 2022

Abstract
Here a new method of modeling the thermal emissions of exoplanets is described, in which the temperature gradient of an exoplanet is approximated by splitting it into N zones. First, we seek to determine how much this method differs from a simple dayside–nightside model used by previous researchers and found that the difference between the N-zone and the dayside–nightside models is greatest during the primary transit of the exoplanet, and for large temperature gradients. Next, we determine under what conditions EXONEST, a Bayesian inference software package, is able to correctly determine the model used to generate synthetic light-curve data. EXONEST is best able to determine the model used to generate synthetic data when the mass of the exoplanet is known, the added noise to the data is low, and the thermal emissions are large compared to the ellipsoidal variations. Finally, EXONEST was used to analyze photometric data for exoplanets Kepler-41b and Kepler-412b, and the dayside brightness temperatures were estimated to be 2574 ± 59 and 2496 ± 64 K, and those of the nightside were estimated to be 860 ± 316 and 874 ± 333 K for Kepler-41b and Kepler-412b, respectively. Finally, we found that the hottest zone for both planets was the zone nearest the terminator on the dayside of the exoplanet. This surprising result suggests that the model is better applied to exoplanets with little to no heat recirculation.
X-Ray and GeV-γ-Ray Emission Property of TeV Compact Symmetric Object PKS 1413+135 and Implication for Episodic Jet Activity
Authors: Gan Ying-Ying , Zhang Jin , Yao Su , Zhang Hai-Ming , Liang Yun-Feng , Liang En-Wei 
Published: November 2022

Abstract
PKS 1413+135, a compact symmetric object (CSO) with a two-sided parsec-scale structure in its miniature radio morphology, is spatially associated with 4FGL J1416.1+1320 and recently detected with MAGIC telescopes. We comprehensively analyze its X-ray and gigaelectronvolt γ-ray observation data to reveal its high-energy radiation physics. It is found that the source is in a low-flux stage before MJD 58500 and experiences violent outbursts after MJD 58500 in the gigaelectronvolt band. The flux at 10 GeV varies by ∼3 orders of magnitude, and the gigaelectronvolt-flux variation is accompanied by clear spectral variation, which is characterized as a soft log-parabola spectrum in the low-flux state and a hard power-law spectrum in the bright flares. The amplitude of the variability of X-rays is lower than that of γ-rays, and no correlation of variability between γ-rays and X-rays is observed. Fitting the broadband spectral energy distribution during a gigaelectronvolt outburst with a multi-zone leptonic model, we show that the gigaelectronvolt γ-rays are attributed to the external Compton process while the X-rays are a hybrid of several components. The predicted teraelectronvolt γ-ray flux during the gigaelectronvolt outburst is consistent with the detection of MAGIC telescopes. These results, together with its CSO radio morphology, imply that PKS 1413+135 has episodic nuclear jet activities. The weak γ-ray emission before MJD 58500 may be from its sub-parsec-/parsec-scale jet component powered by previous activities, and the violent outbursts with short timescale variability after MJD 58500 could be attributed to the recently restarted jet activity.
A Machine Learning Framework to Predict Images of Edge-on Protoplanetary Disks

Published: November 2022

Abstract
The physical structure and properties of protoplanetary disks are typically derived from spatially resolved disk images. Edge-on disks in particular provide an important view point on the vertical structure and degree of settling of disks. Such analyses rely on radiative transfer (RT) calculations that are generally computationally intensive due to the high optical depth of disks. Here we present a machine learning framework that has the potential to dramatically speed up the forward modeling process by approximating the results of RT calculations. This framework, trained on an initial set of RT calculations, utilizes an autoencoder neural network to enable the generation of synthetic scattered light images of edge-on disks directly from a set of physical parameters. We demonstrate that this framework generates synthetic images 2–3 orders of magnitude faster than using RT calculations. These machine learning-generated images appear to approximate the RT images well, in particular preserving their size and shape. We also find a strong correlation between the latent space representations of the generated disk images and several of their associated physical parameters. Finally, we discuss potential changes to the framework, such as methods to further improve the image quality, extending the framework to multiple wavelengths, and inverting the process to infer physical parameters from observed images. Overall, these new tools have the potential to enable a more efficient and uniform analysis of edge-on disk properties and the initial conditions of planet formation.
The Effect of Primordial Black Holes and Streaming Motions on Structure Formation
Authors: Atrio-Barandela F. 
Published: November 2022

Abstract
Primordial black holes could be an important component of the dark matter in the universe. If they exist, they would add a Poisson component to the matter power spectrum. The extra power would speed up the emergence of dark matter halos that seed the formation of first stars and galaxies. Kashlinsky suggested that the additional velocity fluctuations would accelerate the infall of baryons onto the dark matter potential wells. We analyze the effect of primordial black holes on the baryon infall from recombination to reionization and find the correction to be a few percent of the power suppression first identified by Tseliakhovich & Hirata. However, the dynamical effect of this correction in addition to the extra power speeds up the formation of halos in the mass range of 104–105−6
M
⊙, while slightly decreasing the formation of those in the range 106–108
M
⊙, confirming earlier analytic estimates and recent results of numerical simulations.
Une ténébreuse collaboration : Balzac, Hetzel, Chlendowski, Bertall, Gavarni
Authors: Baroni Silvia 
Published: November 2022

L’article analyse la collaboration entre Balzac, les éditeurs Hetzel et Chlendowski, et les illustrateurs Bertall et Gavarni pour la publication de trois œuvres illustrées : Philosophie de la vie conjugale , Paris marié et Petites misères de la vie conjugale . Nous nous interrogeons d’abord sur une question légale : comment Hetzel a-t‑il pu publier Paris marié , alors que Balzac avait signé avec Chlendowski un contrat qui l’empêchait de publier les Petites misères de la vie conjugale chez d’autres éditeurs dans un délai de six mois ? Nous tentons d’approfondir ensuite la collaboration entre Balzac et les deux illustrateurs ; alors que l’exemple de Bertall met en lumière certaines ambiguïtés dans le rapport de l’illustrateur avec le romancier, le cas de Paris marié , où l’illustration est « un libre commentaire » du texte écrit réalisé à l’insu de Balzac, témoigne de l’indépendance croissante de l’illustrateur, ce dernier dépendant de l’éditeur plutôt que de l’écrivain.
Balzac et ses « aides de camp »
Authors: Méra Brigitte 
Published: November 2022

Il s’agira de s’interroger sur la puissance d’élucidation de l’expression et de son origine. C’est en 1835, que Belloy et Grammont sont engagés comme secrétaires pour corriger les Œuvres complètes de Saint-Aubin , Balzac n’en ayant ni le temps ni le désir. Par la suite, une collaboration plus protéiforme s’établit grâce à la presse et à un apprentissage collectif. Cependant, peu de remaniements se feront et sans contrôle de l’auteur ; si bien que le néologisme « modernité » ne sera nullement relevé, 41 ans pourtant avant Baudelaire. L’Excommunié corrigé essentiellement par Belloy en raison d’un incendie, présente, quant à lui, et sous les corrections, un Balzac autrement plus fécond que le ou les secrétaires. Quant aux Contes artistes , l’auteur s’efforce d’obtenir des détails sur la peinture et la musique autour de lui, mais s’arroge le droit de les modifier en consultant plutôt Diderot et la vie de Beethoven. Par conséquent, et en conclusion, l’écrivain fera peu appel à ses aides de camp pour de simples raisons : il travaille sur les placards, et sa discipline est plutôt solitaire. Aussi la modernité balzacienne est bel et bien l’expression d’une originalité personnelle, irremplaçable.
Balzac et Dostoïevski : une collaboration inattendue
Authors: Aubin Marie-Christine 
Published: November 2022

Si, dans le langage courant, l’idée de collaboration sous-entend souvent le fait de travailler ensemble à une œuvre commune dans un espace commun, il peut aussi y avoir des collaborations en quelque sorte décalées, soit dans le temps soit dans l’espace. Ainsi Balzac, qui entrevoit déjà son lecteur comme cocréateur de son œuvre, n’aurait sûrement pas nié que non seulement les auteurs qui ont nourri sa pensée et son imagination ont pu jouer le rôle de collaborateurs de ses œuvres – Dante ne lui a-t‑il pas soufflé le titre de sa Comédie humaine ? – mais aussi que lui-même pourrait jouer un rôle semblable auprès de jeunes auteurs. C’est ce qui s’est produit avec Dostoïevski qui, à dix-sept ans, en 1838, a découvert Balzac et s’est pris de passion pour ses écrits qu’il a lus d’un trait l’été suivant. L’influence de Balzac sur Dostoïevski est telle que celui-ci décide de le prendre pour maître et d’apprendre le métier d’écrivain en traduisant Eugénie Grandet qu’il considère comme « une merveille ». Phrase après phrase, il réfléchit, non seulement au sens, mais aussi aux émotions qu’il ressent à la lecture du roman. Puis, au fil de sa traduction, il se demande comment construire un roman, créer des personnages authentiques, décrire des lieux de telle sorte qu’on y retrouve la vivacité et l’expressivité qu’il a ressenties à la lecture. Il apprend à observer le monde et à en tirer des leçons, à penser son vécu d’une manière nouvelle, autant de réflexions qui contribueront à la formation littéraire du grand écrivain. Cette traduction, commencée en 1843 alors que Dostoïevski n’avait que 22 ans, fut, en 1844, sa première publication. L’année suivante paraissait son premier roman, Les Pauvres gens , où l’on retrouvera, selon Leonid Grossman, bien des caractéristiques du maître, car Dostoïevski « avait lu [Balzac] au point de l’imiter, au point de ressentir le besoin de partager son œuvre en la traduisant, et même au point d’adopter la terminologie et le style de son idole littéraire. » Par sa traduction, Dostoïevski n’a pas seulement établi les bases de ce qu’il allait devenir comme écrivain, il a contribué à la diffusion, mais aussi à l’aura, de l’œuvre balzacienne, du vivant de l’auteur comme dans sa postérité.
Réflexions sur les portes et les fenêtres dans La Comédie humaine
Authors: Dupuis Danielle 
Published: November 2022

Portes et fenêtres figurent par centaines dans La Comédie humaine . C’est, bien sûr, en tant qu’observateur des réalités de son époque que Balzac s’est intéressé à ces éléments de l’environnement quotidien de ses personnages. Mais il en a fait surtout usage en tant que romancier. Portes et fenêtres par les scènes qui leur sont inhérentes, relevant d’une esthétique picturale, théâtrale voire cinématographique avant l’heure, scandent l’intrigue à moins qu’elles ne soient directement à l’origine du drame. Elles ne sont donc jamais évoquées gratuitement et par elles nous avons accès à ce qui aurait pu nous être dérobé : le huis clos de la vie privée.
Expectations of learner nurses in sampled clinical areas of the Limpopo province, South Africa
Authors: Mafumo Julia L. , Netshikweta Mutshinyalo L. 
Published: November 2022

Background: Nurse training in South Africa requires placing learner nurses in real-life setting for them to gain practical experience. To complete their training and be competent practitioners, learner nurses must have expectations and aspirations when they go for practice.Aim: This study sought to understand learner nurses’ expectations at clinical learning areas during placement.Setting: Four clinical learning areas in the Limpopo province were purposely sampled. Tertiary, regional and district hospitals were sampled to obtain information from different levels of care.Methods: A qualitative, descriptive and contextual design was used to explore the expectations of learner nurses during clinical placements. Permission to conduct the study was obtained from various bodies and ethical considerations were ensured. Nonprobability purposive sampling was used, and six focus groups were formed. Each focus group discussion (FGD) had six to eight participants. The FGDs were according to level of study, with the third and fourth levels each having two FGDs because of the number of participants.Results: The following three themes emerged: milieu in the clinical learning areas, learning in the clinical areas and self-actualisation.Conclusion: The clinical learning areas are institutions of promoting learning through practice. They should promote learning and offer support to learners so that learners meet their expectations, which may prevent discouragement and attrition.Contribution: This study adds to the body of knowledge in nursing education and practice because when students’ expectations are met, their training outcome might be positive leading to competent professional nurses.
Experiences and coping strategies of parents living with adolescents misusing nyaope substance
Authors: Masombuka Jan , Mathibela Faith 
Published: November 2022

Background: Nyaope is a South African substance whose usage continues to escalate among young people. Regrettably, the negative effects of this scourge impact not only the misusers but also their parents who unavoidably have to endure the problems associated with their adolescents’ dependence.Aim: The study sought to explore the experiences and coping strategies of parents living with adolescents who misuse nyaope.Setting: The study was undertaken in Soshanguve township, situated in the north of the city of Tshwane in the Gauteng province of South Africa.Methods: Using a qualitative approach, the study adopted dimensions of both explorative and descriptive designs to develop an in-depth understanding of experiences and coping strategies of parents living with adolescents who misuse nyaope in Soshanguve Township. Individual face-to-face semistructured interviews through purposive sampling were conducted by the researchers to collect data from eight parents of such adolescents.Results: Three themes emerged, namely parents’ experiences of how they detected the onset of the adolescents’ misuse of nyaope, effects of adolescents’ misuse of nyaope on parents and family as a whole and parents’ coping strategies in dealing with the adolescents.Conclusion: From the shared stories, it is evident that parents are overly concerned about the extent of damage cause by adolescents’ misuse of nyaope within the family system.Contribution: This study will enable scholars in the field of substance misuse to conduct further research on the phenomenon and generate new knowledge that will contribute towards formulating future policies and implementing new intervention strategies.
