Charge Coupled Devices (CCDs) are workhorses of observational astronomy. These chips are commonly used as imaging detectors in telescopes, but they have wide applications from spectroscopy to drug discovery. This paper presents read-out results from Skipper CCDs recently developed at Berkeley Labs which feature low readout noise.
Astronomers find evidence for dark matter using the universe as their laboratory. How can we try to detect these particles on Earth?
Einstein’s theory of General Relativity predicts all manner of strange astrophysical behaviors. Can we hope to observe these effects from supermassive black holes?
Take a look at three different papers written by graduate students on distant galaxies, waves on the Sun, and mapping the Milky Way.
Observational astronomers often need data from sophisticated, expensive, and rare telescopes perched on top of mountains or the edge of space. The authors of this paper showcase a totally different technique that harnesses a Yahoo! image search to figure out the orbit of a comet.
