摘要:

我们提出了一个创新的新项目的第一份报告,名为“RAD@home”,公民科学研究合作实验室建立在免费的网络服务,如Facebook,谷歌,Skype,美国宇航局Skyview,NED,TGSS等。这是印度的第一个此类网络,一个零资金,零基础设施,人力资源网络,教育和直接参与研究,数百名受过科学教育的印度本科生,无论他们在该国的正式就业和家庭位置如何。专业的国际合作者参与了对合作实验室发现的物体的后续观察和出版。在这里,我们提出了十个新发现的候选情景射电星系,已经提出了GMRT,和十个更有趣的情况下,其中包括,位于新的Mpc尺度的灯丝,可能跟踪宇宙学星系团吸积从宇宙网的三叶射电星系。另外,还发现了两个新的类Speca星系。我们用斯巴鲁和XMM-牛顿望远镜进行的后续观测的早期分析显示,Speca可能是该星系团的新成员,是一个快速旋转,质量极大的恒星形成盘星系。具有巨大射电瓣的类斑大质量星系,可能是早期宇宙中亮类星体的残留物,也可能是第一质量星系中第一个超大质量黑洞的残留物。由于Speca星系的发现不需要大型望远镜的新数据,而是免费的归档无线电光学数据,这些早期结果展示了RAD@home的发现潜力,以及它如何帮助资源丰富的专业人士,并通过互联网为欠发达地区的资源贫乏的人们展示了学术增长的模式。

英文摘要:

We present the first report on an innovative new project named "RAD@home", a citizen-science research collaboratory built on free web-services like Facebook, Google, Skype, NASA Skyview, NED, TGSS etc.. This is the first of its kind in India, a zero-funded, zero-infrastructure, human-resource network to educate and directly involve in research, hundreds of science-educated under-graduate population of India, irrespective of their official employment and home-location with in the country. Professional international collaborators are involved in follow up observation and publication of the objects discovered by the collaboratory. We present here ten newly found candidate episodic radio galaxies, already proposed to GMRT, and ten more interesting cases which includes, bent-lobe radio galaxies located in new Mpc-scale filaments, likely tracing cosmological cluster accretion from the cosmic web. Two new Speca-like rare spiral-host large radio galaxies have also been been reported here. Early analyses from our follow up observations with the Subaru and XMM-Newton telescopes have revealed that Speca is likely a new entry to the cluster and is a fast rotating, extremely massive, star forming disk galaxy. Speca-like massive galaxies with giant radio lobes, are possibly remnants of luminous quasars in the early Universe or of first supermassive black holes with in first masssve galaxies. As discoveries of Speca-like galaxies did not require new data from big telescopes, but free archival radio-optical data, these early results demonstrate the discovery potential of RAD@home and how it can help resource-rich professionals, as well as demonstrate a model of academic-growth for resource-poor people in the underdeveloped regions via Internet.
