On the Origin of Asymmetries in Bilateral Supernova Remnants

AIMS: We investigate whether the morphology of bilateral supernova remnants (BSNRs) observed in the radio band is determined mainly either by a non-uniform interstellar medium (ISM) or by a non-uniform ambient magnetic field. METHODS: We perform 3-D MHD simulations of a spherical SNR shock propagating through a magnetized ISM. Two cases of shock propagation are considered: 1) through a gradient of ambient density with a uniform ambient magnetic field; 2) through a homogeneous medium with a gradient of ambient magnetic field strength. From the simulations, we synthesize the synchrotron radio emission, making different assumptions about the details of acceleration and injection of relativistic electrons. RESULTS: We find that asymmetric BSNRs are produced if the line-of-sight is not aligned with the gradient of ambient plasma density or with the gradient of ambient magnetic field strength. We derive useful parameters to quantify the degree of asymmetry of the remnants that may provide a powerful diagnostic of the microphysics of strong shock waves through the comparison between models and observations. CONCLUSIONS: BSNRs with two radio limbs of different brightness can be explained if a gradient of ambient density or, most likely, of ambient magnetic field strength is perpendicular to the radio limbs. BSNRs with converging similar radio arcs can be explained if the gradient runs between the two arcs.Comment: 14 pages, 8 Figures; paper accepted for publication in A&A; the paper with high-resolution figures can be downloaded at http://www.astropa.unipa.it/~orlando/PAPERS/sorlando_6045.pd

Russian Migration and Psychological Aspect

The problem of regional migration is treated in the article. The development of the Far Eastern territories is a priority now. The government has developed many large-scale projects aimed at supporting the remote region, but the problem of emigration of the economically active population has not settled since 1991. The problem of the outflow of promising young personnel from its territory is particularly acute. The purpose of this research is to study the reasons for the migration of young people from the Primorsky Region - one of the regions of the Far East. The main tasks were to obtain visions of migration moods and motivation of migration behavior of students. The study used a psychological verbal-communicative method - a survey in which a specially designed list of questions was used as a means to collect information from the respondent. The survey covered about 1,000 respondents between the ages of 15 and 30.  The research has shown that the main reason for emigration of school graduates is the opportunity to progress, studying in prestigious domestic and foreign universities, working in the largest Russian and foreign companies, that not enough represented here. Excellent and good rated school graduates prefer to enter Moscow and St. Petersburg universities. This means that most prospective workers in the future want to leave the territory of the region. Analysis of the responses of the university graduates revealed the prevalence of negative expectations about their future and the future of the territories. The data indicated that the main reasons to leave the country and the Primorsky Region are low job prospects for university graduates, lack of self-realization possibilities, low wages and the instability of the region’s political and socio-economic situation. In addition, the situation is exacerbated by the fact that respondents, for the most part, do not know about the projects that are being implemented in the region and do not see career prospects, which confirms the implementation of many strategic projects of the region only on paper. The lack of measures to prevent the emigration of young people will have a number of negative economic and social consequences, one of which is the reduction of competitevness of the territory. Creating favorable conditions for young people in the region, active public policy to attract young skilled professionals in Primorye is a prerequisite for the development of the region's intellectual capital and a guarantee of its dynamic socio-economic development.The problem of regional migration is treated in the article. The development of the Far Eastern territories is a priority now.

El desarrollo de los territorios del Lejano Oriente es una prioridad ahora. El gobierno ha desarrollado muchos proyectos a gran escala destinados a apoyar a la región remota, pero el problema dela emigración de la población económicamente activa no se ha resuelto desde 1991. Elproblema de la salida de jóvenes prometedores de su territorio es particularmente grave. El propósito de esta investigación es estudiar las razones de la migración de jóvenes de la región de Primorsky, una de las regiones del Lejano Oriente. Las tareas principales fueron obtener visiones de los estados de ánimo migratorios y la motivación del comportamiento migratorio de los estudiantes. El estudio utilizó un método psicológico verbal-comunicativo, una encuesta en la que se utilizó una lista especialmente diseñada de preguntas como un medio para recopilar información del encuestado. La encuesta abarcó a aproximadamente 1,000 encuestados entre las edades de 15 y 30. La investigación ha demostrado que la razón principal de la emigración de los graduados de laescuela es la oportunidad de progresar, estudiando en prestigiosas universidades nacionales y extranjeras, trabajando en las mayores universidades rusas y extranjeras. empresas, que no están suficientemente representadas aquí. Los graduados de escuelas excelentes y con buena calificación prefieren ingresar a las universidades de Moscú y San Petersburgo. Esto significa que la mayoría de los futuros trabajadores en el futurodesean abandonar el territorio de la región. El análisis de las respuestas de los graduados universitarios reveló la prevalencia de expectativas negativas sobre su futuro y el futuro de los territorios. Los datos indicaron que las principales razones para abandonar el país y la región de Primorsky son las bajas perspectivas laborales paralos graduados universitarios, la falta de posibilidades de autorrealización, los bajos salarios y la inestabilidad de la situación política y socioeconómica de la región.Además, la situación se ve exacerbada por el hecho de que los encuestados, en su mayor parte, no conocen los proyectos que se están implementando en la región y no ven perspectivas de carrera, lo que confirma la implementación de muchos proyectos estratégicos de la región solamente. en papel. La falta de medidas para prevenir la emigración de los jóvenes tendrá una serie de consecuencias económicas y sociales negativas, una de las cuales es la reducción de la competitividad del territorio. La creación de condiciones favorables para los jóvenes de la región, una política pública activa paraatraer a jóvenes profesionales calificados en Primorye es un requisito previo para el desarrollo del capital intelectual de la región y una garantía de su dinámico desarrollo socioeconómico

Aspect angle for interstellar magnetic field in SN 1006

A number of important processes taking place around strong shocks in supernova remnants (SNRs) depend on the shock obliquity. The measured synchrotron flux is a function of the aspect angle between interstellar magnetic field (ISMF) and the line of sight. Thus a model of non-thermal emission from SNRs should account for the orientation of the ambient magnetic field. We develop a new method for the estimation of the aspect angle, based on the comparison between observed and synthesized radio maps of SNRs, making different assumptions about the dependence of electron injection efficiency on the shock obliquity. The method uses the azimuthal profile of radio surface brightness as a probe for orientation of ambient magnetic field because it is almost insensitive to the downstream distribution of magnetic field and emitting electrons. We apply our method to a new radio image of SN 1006 produced on the basis of archival VLA and Parkes data. The image recovers emission from all spatial structures with angular scales from few arcseconds to 15 arcmin. We explore different models of injection efficiency and find the following best-fitting values for the aspect angle of SN 1006: phi=70 +/- 4.2 deg if the injection is isotropic, phi=64 +/- 2.8 deg for quasi-perpendicular injection (SNR has an equatorial belt in both cases) and phi=11 +/- 0.8 deg for quasi-parallel injection (polar-cap model of SNR). In the last case, SN 1006 is expected to have a centrally-peaked morphology contrary to what is observed. Therefore, our analysis provides some indication against the quasi-parallel injection model.Comment: Accepted for publication in MNRA
