The morphology of the Magellanic Clouds revealed by stars of different age: results from the DENIS survey

The spatial distribution of sources populating different regions of the colour-magnitude diagram (I-J, I) extracted from the DENIS catalogue towards the Magellanic Clouds (DCMC -- Cioni et al. 2000) reveal significantly different morphologies. Each region is associated to a different age group. The Large Magellanic Cloud (LMC) shows an extended circular shape with a prominent, off center bar, a nucleus and irregular spiral arms. The Small Magellanic Cloud shows a perturbated structure with a prominent central concentration of stars. Old and young populations are offset from one another.Comment: 4 pages and 7 figures, accepted for publication in A&A Journal Letter

Magellanic Cloud Periphery Carbon Stars IV: The SMC

The kinematics of 150 carbon stars observed at moderate dispersion on the periphery of the Small Magellanic Cloud are compared with the motions of neutral hydrogen and early type stars in the Inter-Cloud region. The distribution of radial velocities implies a configuration of these stars as a sheet inclined at 73+/-4 degrees to the plane of the sky. The near side, to the South, is dominated by a stellar component; to the North, the far side contains fewer carbon stars, and is dominated by the neutral gas. The upper velocity envelope of the stars is closely the same as that of the gas. This configuration is shown to be consistent with the known extension of the SMC along the line of sight, and is attributed to a tidally induced disruption of the SMC that originated in a close encounter with the LMC some 0.3 to 0.4 Gyr ago. The dearth of gas on the near side of the sheet is attributed to ablation processes akin to those inferred by Weiner & Williams (1996) to collisional excitation of the leading edges of Magellanic Stream clouds. Comparison with pre LMC/SMC encounter kinematic data of Hardy, Suntzeff, & Azzopardi (1989) of carbon stars, with data of stars formed after the encounter, of Maurice et al. (1989), and Mathewson et al. (a986, 1988) leaves little doubt that forces other than gravity play a role in the dynamics of the H I.Comment: 30 pages; 7 figures, latex compiled, 1 table; to appear in AJ (June 2000

Infrared Surface Brightness Analysis of Galaxies in Compact Groups

Images of 7 Compact groups of galaxies (CG) were obtained using the 2.1m telescope in San Pedro Martir (B.C. Mexico) equipped with the NIR camera CAMILA. The NIR images trace the mass of the galaxies, through the oldest and more evolved stellar populations. The goal of this project is to search for evidence of morphological perturbations correlated with the level of activity (AGN or star formation) of the galaxies. We find that the level of perturbation is well correlated with activity observed in optical spectrocopy (Coziol et al. 2004). Evidence for perturbations decreases from more active groups to less active groups, confirming the classification. Our analysis suggests that galaxies in more active groups are undergoing important transformations due to interaction and merging and that the whole groups is on a merger path. Galaxies in less active CG have gone through similar processes in the recent past and are either in a final merging phase or in equilibrium due to a more massive halo of dark matter.Comment: 2 pages, 1 figure, Proc.

Rehabilitacja psychologiczna (i emocjonalna readaptacja) żołnierzy powracających ze strefy walki

The current article presents the essence of theoretical provisions related to professional, psychological, and social rehabilitation of those servicemen who returned from the combat zone in eastern Ukraine. It is noted that psychological rehabilitation is considered as a kind of psychological assistance in that part, which aims to restore the lost (impaired) mental capabilities, emotional functioning, and health. It is emphasized that the object of psychological rehabilitation are people who have received combat mental trauma, which is manifested acutely or delayed in time. The principles of psychological rehabilitation are highlighted: the principle of prevention, the principle of urgency, the principle of the proximity of rehabilitation institutions to the line of combat, the principle of simplicity of measures, the principle of continuity and individualization of measures. The experience of direct rehabilitation work with the military is described; recommendations for optimization of the rehabilitation process are given. It is emphasized that in the process of rehabilitation there is a place for both, unlocking the system of psychological protection of servicemen, and creating an emotionally supportive atmosphere in the group, and for implementing individual and group psychocorrection, training the effective communication skills.W artykule przedstawiono istotę zasad teoretycznych związanych z rehabilitacją zawodową, psychologiczną i społeczną żołnierzy, którzy powrócili ze strefy walki we wschodniej Ukrainie. Należy podkreślić, że rehabilitacja psychologiczna jest uważana za rodzaj pomocy psychologicznej, która ma na celu przywrócenie utraconych (lub dysfunkcyjnych) zdolności poznawczych, funkcjonowania emocjonalnego i zdrowia. Przedmiotem rehabilitacji psychologicznej są osoby, które podejmują pokonanie traumy psychicznej, występującej w formie ostrej lub przewlekłej. Opisano następujące zasady rehabilitacji psychologicznej: zasadę zapobiegania, zasadę pilności, zasadę bliskości instytucji rehabilitacyjnych w stosunku do linii walki, zasadę prostoty środków, zasadę ciągłości i indywidualizacji środków. Ponadto wskazano na doświadczenie bezpośredniej rehabilitacji w wojsku; podano zalecenia dotyczące optymalizacji procesu rehabilitacji. Zaakcentowano, że w procesie rehabilitacji jest miejsce zarówno na odblokowanie zasobów osobistych psychologicznych żołnierzy, jak i stworzenie emocjonalnie wspierającej atmosfery grupowej. Proces rehabilitacji może też obejmować wdrożenie psychoterapii indywidualnej i grupowej oraz szkolenie skutecznych umiejętności komunikacyjnych
