Supplement: "Localization and broadband follow-up of the gravitational-wave transient GW150914" (2016, ApJL, 826, L13)

This Supplement provides supporting material for Abbott et al. (2016a). We briefly summarize past electromagnetic (EM) follow-up efforts as well as the organization and policy of the current EM follow-up program. We compare the four probability sky maps produced for the gravitational-wave transient GW150914, and provide additional details of the EM follow-up observations that were performed in the different bands

Localization and Broadband Follow-up of the Gravitational-wave Transient GW150914

A gravitational-wave (GW) transient was identified in data recorded by the Advanced Laser Interferometer Gravitational-wave Observatory (LIGO) detectors on 2015 September 14. The event, initially designated G184098 and later given the name GW150914, is described in detail elsewhere. By prior arrangement, preliminary estimates of the time, significance, and sky location of the event were shared with 63 teams of observers covering radio, optical, near-infrared, X-ray, and gamma-ray wavelengths with ground- and space-based facilities. In this Letter we describe the low-latency analysis of the GW data and present the sky localization of the first observed compact binary merger. We summarize the follow-up observations reported by 25 teams via private Gamma-ray Coordinates Network circulars, giving an overview of the participating facilities, the GW sky localization coverage, the timeline, and depth of the observations. As this event turned out to be a binary black hole merger, there is little expectation of a detectable electromagnetic (EM) signature. Nevertheless, this first broadband campaign to search for a counterpart of an Advanced LIGO source represents a milestone and highlights the broad capabilities of the transient astronomy community and the observing strategies that have been developed to pursue neutron star binary merger events. Detailed investigations of the EM data and results of the EM follow-up campaign are being disseminated in papers by the individual teams. </p

Psychoeducational intervention based on groupwork in diabetic subjects

Background: The chronic patient experiences a persistent condition of stress which makes it very difficult to maintain constructive reactions to the illness. The responsiveness of the environment is decisive: it may be supportive insomuch as it reinforces the adaptive characteristics of the subject, or it may challenge some areas of personal expression, taking on the dimension of ‘patient’ as the only terrain for communication with the subject. Materials and methods: Support groups were created consisting of a psychologist, a clinician, a dietician and 12 patients; a service of individual psychotherapy was installed, and lastly a weekly autogenic training programme. Results: The group defined itself as a dynamic whole, the essence of which was in the intercommunication; the subjects involved felt they could speak with greater ease of their own emotive experiences, of their social and family relationships. The exchange of information allows deeper insight into the illness and permits a more suitable reformulation of the strategies needed to address it. Conclusions: This type of intervention permitted a greater emotive involvement in educational terms towards the suggestions of the team. The benefits reported by the patients were described as follows: the security of having someone to turn to, a greater capacity to accept one’s own situation, the reinforcing of self-esteem and of autonomy, the awareness of being able to participate actively in the positive outcome of the therapies, a more conscious presence in the personal and social relations and lastly, a more appropriate use of the sanitary and social services
