Universe@Home是华沙大学的分布式计算项目,目标是建立第一个模拟的行星数据库,不管是最早的星辰还是最奇异的双生黑洞。这一全面的恒星数据库将会成为全世界的天文学家的一个学术资源,同时也对大众教育提供帮助。




This proposal aims to create the first database of the simulated stellar content of the Universe,from the earliest stars to the most exotic black hole binaries. This comprehensive stellar library willbe a world-wide scientific resource for astronomers, and an educational asset for the public. Witha state-of-the-art suite of computational tools, we can calculate the physical properties of individualstars, evolve them in time, and track how they interact with each other as they age. With this libraryof stellar populations that spans the known range of star formation histories and initial elementalabundances, it is possible to tackle fundamental science questions that have been out of reach ingeneral relativity, astronomy, and cosmology. As a group we will use this database to characterize thepopulation of supernova progenitor stars that have been used to discover the mysterious dark energythat accelerates the expansion of the Universe; we can calculate how (if at all) binary evolutionfacilitates the formation of ultra-luminous X-ray sources, and we can model the number and physicalproperties of neutron stars and black holes that strongly emit gravitational waves that are at theheart of research into gamma-ray bursts – the most energetic explosions known-to-date. The datathat we create can be mined not only to match current observations, but to predict how the skywill appear to future astronomical observatories as new windows to the Universe open. Altogether,this proposal will allow us to consolidate a strong and highly visible research group; an independentcomputational center that trains a new cohort of highly educated students, and communicates withthe public via innovative science venues, and offer a fresh look at the Universe.

2015-03-17: Universe@Home Test, Badges

As on main production server I have added badges to project.

Badges (and points steps) are same as on Universe@Home main project except that all badges for test project have added capital "T" letter into corner of icon.

2015-03-17:Universe@Home Test,奖牌
我们已经在主服务器上加入了奖牌功能。
除了所以奖牌图标上都有“T”字样之外,其它(包括分数节点)都与Universe@Home主项目项目相同。

Next paper published in the Astrophysical Journal
Simulations done with the use of Universe@Home and the analysis performed in the cooperation between University of Warsaw (Poland) and University of Ferrara (Italy) resulted in a research paper publication in the Astrophycial Journal, one of the highest ranked scientific journals worldwide! The article can be found on arXiv: https://arxiv.org/abs/1707.01586

The research on hypothetical quark stars was the first of its kind and gave a few very interesting conclusions. Although we showed that the presence of these objects cannot be proved or rejected on the base of available observations, quark stars have a potential to explain the long gamma ray burst phenomena and the so called "strangelets pollution" problem.

项目方在Astrophysical Journal发表了一篇论文
具体内容不懂,不翻译了。。

2018-03-09: Universe@Home, BHDB application

On our server just start new BHDB (Black Hole Database) application.
First work units release will be testing one, to check if everything is ok with application and points system :)

In near future we will publish more information about it.

2018-03-09: Universe@Home, BHDB 程序
我们在服务器上启用了新的黑洞数据库(Black Hole Database ,BHDB)程序。
我们将会对接下来的首次任务发放进行独立的测试,以确保没有意外发生:)
在不久的将来我们将发布更多的相关信息。

2019-02-28: Universe@Home, We got a grant!

As Krzysztof have already said, we got a grant in the Maestro program. It will allow to continue the project for the next few years. We hope that the project will still provide an exceptionally computational power for the science.

The Maestro program of the National Science Centre aims at providing funding for pioneering research. The research should be done by groups led by senior scientists. The projects must result in extending our understanding of physical phenomena and potentially lead to scientific discoveries. It is one of the biggest funding programs of the NSC.

You can read about the scientific goals here

2019-02-28: Universe@Home, 我们拿到拨款了!
如Krzysztof之前说的那样,我们拿到了一笔来自“大师”计划(The Maestro program)的拨款。这笔拨款能维持我们的项目运作数年,我们希望本项目能够继续为科学研究提供特别的计算能力。
The Maestro program 是国家科学中心为资助尖端研究而设立的项目。他们挑选资助项目的条件非常苛刻,研究须由资深科学家带领团队完成,且要求项目成果能够拓展我们对于物理现象的认知、具有产生科学发现的潜力。Universe@home 是国家科技中心赞助力度最大的一个项目。

合成的黑洞数据库已发布!
我们发布第一个合成数据库的,其中包括双星中的黑洞(即具有引力约束的伴星)和作为单个对象存在的双星。后者可能是由巨大的单颗恒星形成的(至少比太阳大二十倍),或者更可能是由于双星破坏和恒星合并所致。这项研究是其他更深入分析银河系和其他星系中黑洞种群的起点。论文在https://ui.adsabs.harvard.edu/abs/2019ApJ...885....1W
数据库在https://universeathome.pl/universe/bhdb.php
