近日,中国地质大学生物地质与环境地质国家重点实验室李超教授团队在国际著名地球化学期刊《Geochimica et Cosmochimica Acta》(Nature Index)上发表题为“Spatiotemporal redox heterogeneity and transient marine shelf oxygenation in the Mesoproterozoic ocean”(中...
近日,中国地质大学生物地质与环境地质国家重点实验室李超教授团队在国际著名地学期刊《Geology》上发表了题为“Sulfur isotope evidence for transient marine-shelf oxidation duringthe Ediacaran Shuram Excursion”的学术论文,该论文通过定量数值模拟的方法首次发现了埃迪卡拉纪碳循环剧烈扰动时期(又称“Shu...
A new robotic camera with the ability to capture hundreds of thousands of stars and galaxies in a single shot has taken its first image of the sky, an event astronomers refer to as "first light." The ...
2017年4月,国际著名期刊《Geochimica et Cosmochimica Acta》刊发了中国地质大学生物地质与环境地质国家重点实验室李超教授团队的研究文章--南华盆地寒武纪早期深水短暂充氧事件(Transient deep-water oxygenation in the early Cambrian Nanhua Basin, South China)。程猛助理研究员为本文的第一作者...
The mineralogy, petrography, and oxygen-isotope compositions of porphyritic chondrules—dominant chondrule type in most chondrite groups—suggest formation by incomplete melting of isotopically diverse...
We have quantified the effects of a water mass redistribution associated with the propagation of a tsunami wave on the Earths pole path and on the Length-Of-Day (LOD) and applied our modeling results...
We performed an analysis of post-seismic stress relaxation, taking into account generalized linear rheologies. We compared the stress field (and its derived functions) obtained with a classical Maxwel...
We present Chandra/ACIS observations of the bursting X-ray transient SAX J1747.0-2853 performed on 2001 July 18. We detected a bright source at the position of R.A. = 17h47m02.s60 and decl. = -28°52'5...
Supernovaestellar explosions—are incredibly energetic, dynamic events. It is easy to imagine that they are uncommon, but the universe is a big place and supernovae are actually fairly routine. The pr...
Pioneering efforts aiming at the development of multi-messenger gravitational wave and electromagnetic astronomy have been made. An electromagnetic observation follow-up program of candidate gravitati...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
A comprehensive search for variable and transient radio sources has been conducted using ~55,000 snapshot images of the FIRST survey. We present an analysis leading to the discovery of 1,627 variable ...
During the maintained quiescence between solar cycle 23 and 24, two unusually intense (K-indices = 7) global geomagnetic disturbances separated by 6 days occurred. They were followed by a protracted i...
Abstract: CaF$_2$:Yb$^{2+}$ and SrF$_2$:Yb$^{2+}$ crystals have been investigated by a two-color UV + IR transient photoluminescence enhancement technique. The enhancement gives information about both...
In this paper we discuss the recently discovered radio transient in the nuclear region of M\,82. It has been suggested that this source is an X-ray binary, which, given the radio flux density, would r...
