The kitchen is set to be installed between December 22nd and January 8th. “It won’t be in time for Christmas, because as long as the kids are here we need to use the kitchen. But we’re hoping it will be finished by the start of the new school term, a bit like a late Christmas present,” said Lady Camille Barnett, President of the AIDS Foundation.“We still do what we can to give the place a little ‘holiday spirit.’ The kids will have a Christmas party and exchange of gifts. They put up a Christmas tree last week and they’re very proud of it.“At our afterschool program, we have a part-time cook who prepares a meal for the kids – the idea being that once they have a meal at the end of the day they’ll be able to take their medication,” said Lady Barnett. “Our kitchen was in dire need of renovation. The buildings we’re in now were donated to us in the late 1990s, and not much work has ever been done to them because we’ve had to use our resources for other things. CIBC FirstCaribbean’s donation will go towards renovating the kitchen area, which is vital to the work that we do with young people.”Established in 1992, the AIDS Foundation engages in HIV/AIDS education, awareness, advocacy, support, treatment, and prevention. Their afterschool program caters to people of all ages, and has three components: academic, psycho-social, and medical.“On the academic side, we have trained educators who work with the kids from 4:00pm until 5:30pm on school assignments Monday through Thursday. The psycho-social component happens on Friday and it’s all the interaction we do to support them in terms of their health, especially those who are HIV positive. We teach them anything from self-esteem building, to making good choices and life skills. With the medical component we work very closely with the Ministry of Health, because they’re the healthcare providers for these young individuals. We are actively involved with making sure they get to clinic appointments and that they take their medication.“We also found that as some of these kids have grown up, they need help with job preparation and we’re doing that with them as well. So I like to call this the ‘holistic program,’ because we try to support them and meet all of the needs they have. Sometimes it involves housing – at one point our social worker actually housed three of the kids in her home because there was no place for them to go and no one for them to be with. We try to provide complete support for them and at the end of the day we want them to be healthy, productive, and independent young people – that’s the goal,” said Lady Barnett.Part of that process involves creating a “safe space” that is comfortable for program participants. “There’s still a stigma surrounding HIV, and you don’t want the children coming to a place that’s broken down because that’s not good for their self-esteem. You want the place to look nice. We’re receiving help to renovate our stairs soon, because they’re in pretty bad condition. So along with the donation from CIBC FirstCaribbean to renovate our kitchen – all of that is just giving it a little facelift. I think coming to a place that looks decent and not broken down enhances everybody’s self-esteem.”Photo captions: CIBC FirstCaribbean’s donation to the AIDS Foundation will help give the non-profit organisation a much-needed ‘facelift’ in time for the New Year.

Citation: Fermi observations provide insights into the nature of Terzan 5 globular cluster (2019, June 3) retrieved 18 August 2019 from https://phys.org/news/2019-06-fermi-insights-nature-terzan-globular.html Three new millisecond pulsars discovered in Terzan 5 globular cluster Observations of globular clusters (GCs) in our Milky Way galaxy are of high importance for astronomers as they are among the oldest objects in the universe. Therefore, they could serve as natural laboratories for the study of stellar evolution processes.Discovered about a half-century ago, Terzan 5 is a 12-billion-year-old galactic GC located some 19,000 light years away. The cluster has a particularly high central stellar density, high metallicity, and also the highest stellar interaction rate of all GCs in the Milky Way. Terzan 5 is known to host 37 out of 130 millisecond pulsars (MSPs) detected so far, what makes it a record holder when it comes to the largest number of MSPs in a galactic GC. Previous studies of this cluster have also shown that it contains at least two distinct stellar populations with different ages and iron content. This could suggest that Terzan 5 may not be a “true” globular cluster, but a result of a merger of two clusters, for instance, or a remnant of a disrupted galaxy.In order to get more detailed information about Terzan 5, which could verify these possibilities, an international team of astronomers led by Hambeleleni Ndiyavala of North-West University in Potchefstroom, South Africa, decided to analyze new data obtained by the Fermi spacecraft. This dataset allowed the researchers to model the broadband spectral energy distribution (SED) in the cluster.”We therefore aimed to gather more data on Terzan 5 and model the updated SED in a leptonic scenario,” the astronomers wrote in the paper.In particular, the spectral model described in the study postulates four spectral components, namely: low-energy synchrotron radiation (LESR), high-energy synchrotron radiation (HESR), curvature radiation (CR) and inverse Compton (IC). The model also allowed the astronomers to constrain the MSP population’s distribution of spin-down luminosity.According to the study, the updated SED in Terzan 5 is most likely due to a cumulative pulsed emission from a population of embedded MSPs. Moreover, it could be as well attributed to unpulsed emission from the interaction of leptonic winds with ambient magnetic and soft-photon fields.”We obtained new Fermi data that we could fit using a model for the cumulative CR from a population of MSPs embedded within Terzan 5. These data also proved to be constraining for the low-energy tail of the unpulsed IC component, yielding a particle efficiency of ηp~3 percent, depending on the choice of several parameters, notably〈 ̇Evis〉and NMSP,tot,” the paper reads.In concluding remarks, the astronomers underlined the importance of further studies of Terzan 5 and similar clusters to get a more comprehensive view on the nature and properties of galactic GCs in general. They added that such instruments like the Cherenkov Telescope Array (CTA) could be much helpful in identifying new very-high-energy (VHE) GCs.”This will allow us to further scrutinize competing emission models, as well as developing new, more complete and comprehensive ones that might explain the spatial and spectral properties of galactic GCs at an ever increasing level of detail,” the authors of the paper noted.
