Abstract: This article presents a novel type of very long baseline astronomical interferometer that uses the fluctuations, as a function of time, of the intensity measured by a quadratic detector, ...

we investigate the smearing versus sensitivity trade-off, and show that in certain regimes a favourable compromise can be achieved. We show the application of this technique to simulated data from the ...

Astronomers analyzing M87*, the first black hole ever imaged, have discovered that its shadow changes from year to year. The ...

Achieving this resolution with an ordinary telescope would require a dish the size of the Earth, which is clearly not possible. Instead, the EHT uses very long baseline interferometry, which involves ...

A team of international researchers has successfully conducted the first very long baseline interferometry (VLBI) observations at an unprecedented wavelength of 870 micrometers, opening new ...

Scientific instruments onboard also include a neutral atom imager, an extreme ultraviolet camera, and an Earth-Moon Very Long Baseline Interferometry (VLBI) test system. VLBI has a variety of uses ...

Long underwear — a.k.a. long johns ... Merino even offers UV protection — plus, unlike the typical wool, it’s “very soft and feels very nice against your skin,” adds Savala.

亚毫米波段是天文观测的重要窗口，涵盖宇宙再电离及高红移星系普查、宇宙生命起源、黑洞等科学前沿。中国科学院紫金山天文台李婧研究员在《科学通报》2025年第7期“巾帼科苑•女科学家”专辑中发表观点文章，代表中国亚毫米波天文团队结合自身的地理、技术、人才优 ...

现在一提起射电望远镜，人们往往首先就会想起中国天眼FAST，这台借助贵州喀斯特天坑地形修建的望远镜是世界上最大的单天线射电望远镜,总直径500米，观测时跟踪天体的部分有效口径约300米。自建成以来它取得了多次重大发现，是我国天文学家的骄傲。不过，这台 ...

Carl Barus, -of Brown University, recently published by the Carnegie Institution of Washington, a number of interesting applications of achromatic interferometry are described. In the first ...

It can be costly for investors to confuse quick “swing trades” in fashionable companies with long-term holdings that provide reliable returns thanks to consistent and substantive success.
