The separation runs that analyse the northern galactic cap (Sloan Digital Sky Survey, or SDSS Stripes 9-27) have nearly finished - soon we'll be able to wrap all of that data together, and with data from Nathan Cole's PhD thesis, we'll have a nice scientific paper out in the next few months. We'll keep you notified.
用于分析北半球星空(Sloan Digital Sky Survey, or SDSS Stripes 9-27)的分离程序基本上已经接近完成任务,不久之后我们就能够将所有的数据整合到一起,加上Nathan Cole的PhD假设,我们能够在近几个月内发表一篇不错的科学论文。有任何消息我们会及时通知大家的。
That doesn't mean that the separation code will be retired - far from it. We're starting new separation runs (the ones with "mix" in the name) that are testing the robustness of the separation code. We'll be running simulated data sets along side real data to test several aspects of the stream-fitting process. The main questions are: What would Milkyway@home do if something different from our model exists in the data? And how different would that something have to be in order to modify our results?
但是这并不意味着我们的分离程序将要废弃——恰恰相反,我们正在开始新的分离工作(名字里带有“mix"的)来测试程序的健康程度。我们将会同时运行测试数据和实际数据,以便测试stream-fitting过程的不同方面。主要的问题是:如果我们的模型中的数据有所变化,我们将如何继续挤奶?以及区别的程度达到多少的时候,我们就需要修改我们的结果?
Also, the release of SDSS Data Release 8 earlier this year gives us access to several stripes of data in the southern galactic cap. We are currently processing this data (It's not as continuous as the northern data, so we have to cut out areas with spotty data), and it will eventually run on Milkway@home.
同时,今年早些时候发布的SDSS Data Release 8让我们能够访问一些来自南半球的星空的数据。我们正在分析这些数据(这些数据并不像北半球这么连续,因此我们需要将区域进行点状切割),这些工作最终会在Milkyway@home上运行。
We are also looking to improve the code on Milkyway@home. My brand new paper studies the distribution function of stars in the Milky Way halo, and provides a new convolution kernel that should make Milkyway@home more effective. There are a few other results from that paper, and inside work, that we would like to implement in the Milkyway@home searches. When we update these functions, we will run stripes over again and look for differences.
我们同时也在着手改进Milkyway@home的代码。My brand new paper studies the distribution function of stars in the Milky Way halo, and provides a new convolution kernel that should make Milkyway@home more effective. 这篇论文中以及我们的工作中还有其他的一些结果,这些结果我们将会最终实施到Milkyway@home的搜索中。等我们更新了这些功能,我们将会对一些样本数据再次进行运算,看结果会有什么不同
Long story short: We're almost done with one part of Milkyway@home's mission, but there's still plenty to do. Happy Crunching!
简而言之:我们基本上完成了Milkyway@home的第一乐章,而未来还有很多在等着我们去做。努力算吧!
