Basic characteristics and accumulation mechanism of Sinian−Cambrian giant highly mature and oil-cracking gas reservoirs in the Sichuan Basin, SW China

Energy Exploration & Exploitation, 2018
Old Mesoproterozoic−Cambrian successions have been regarded as an important frontier field for global oil and gas exploration in the 21st century. This has been confirmed by a recent natural gas exploration breakthrough in the Sinian and Cambrian strata,

A Resonant Beginning for the Solar System’s Terrestrial Planets

The Astrophysical Journal
In the past two decades, transit surveys have revealed a class of planets with thick atmospheres—sub-Neptunes—that must have completed their accretion in protoplanet disks.

Multiarm spirals on the periphery of disc galaxies

Open Astronomy, 2018
Spiral patterns in some disc galaxies have two arms in the centre, and three or more arms on the periphery. The same result is also obtained in numerical simulations of stellar and gaseous discs.We argue that such patterns may occur due to fast cooling ...

The Long-Lasting Activity in the Flat Spectrum Radio Quasar (FSRQ) CTA 102

Galaxies, 2019
The flat spectrum radio quasar CTA 102 ( z = 1 . 032 ) went through a tremendous phase of variability. Since early 2016 the gamma-ray flux level has been significantly higher than in previous years. It was topped by a four month long giant outburst,

First Detection of Molecular Gas in the Giant Low Surface Brightness Galaxy Malin 1

The Astrophysical Journal Letters
After over three decades of unsuccessful attempts, we report the first detection of molecular gas emission in Malin 1, the largest spiral galaxy observed to date, and one of the most iconic giant low surface brightness galaxies.
