An international team of astronomers has performed X-ray, ultraviolet, and optical observations of an X-ray source known as 1RXS J165424.6-433758. Results of the observational campaign, published June 8 on the pre-print server ...
An international team of astronomers has analyzed the data from the latest phase of the Sloan Digital Sky Survey (SDSS). They discovered eight new cataclysmic variables (CV) systems. The finding is reported in a paper published ...
Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images of persistent, intense ...
