‘The dawn of a new era in astronomy’（图）
天文学 银河系 黑洞
2023/6/21
Not long ago, the idea of photographing a black hole was as quixotic as photographing a unicorn. Now, scientists have not one but two images of two different supermassive black holes — and they both l...

First Observations Merging Neutron Stars Mark New Era Astronomy
2017/10/26
Two months ago, the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO) notified astronomers around the world of the possible detection of gravitational waves from the merger of two ne...
Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. The titanic supernova, called Supernova 1987A (SN 1987A), blazed with the power of 100 million suns ...
Radio properties of supernova outbursts remain poorly understood despite longstanding campaigns following events discovered at other wavelengths. After ~ 30 years of observations, only ~ 50 supernovae...
Spectroscopic and photometric surveys of the Milky Way and its stellar clusters in the Gaia era
Spectroscopic photometric surveys o stellar clusters

The DRAO Synthesis Telescope the post-CGPS Era
2011/1/13
The DRAO ST was used for the past 15 years as the primary instrument for the Canadian Galactic Plane Survey. This has been a spectacularly successful project, advancing our understanding of the Milky ...
Ultraviolet Spectroscopic Observations of Coronal Streamers in the SOHO Era
Sun corona ultraviolet
2010/9/16
Measurements made with the Ultraviolet Coronagraph Spectrometer (UVCS) on the Solar and Heliospheric Observatory can be used to determine physical parameters in the solar corona such as hydrogen and i...
The diffuse high-energy gamma-ray emission of the Milky Way arises from interactions of cosmic-rays (CRs) with interstellar gas and radiation field in the Galaxy. The neutral hydrogen (H I) gas compon...
The Cosmological Evolution of Blazars and the Extragalactic Gamma-Ray Background in the Fermi Era
Cosmological Evolution Blazars Extragalactic Gamma-Ray Background
2010/3/8
The latest determination of the extragalactic gamma-ray background (EGRB) radiation by Fermi is compared with the theoretical prediction of the blazar component by Inoue & Totani (2009; hereafter IT09...
