Using NASA's Chandra spacecraft, European astronomers have detected a diffuse X-ray emission around an ultraluminous X-ray pulsar in the galaxy NGC 5907. The newly detected emission could be an expanding nebula powered by ...
Astronomers from Italy and Spain have detected a new blazar by analyzing data from two astronomical surveys. The newly found object, designated DESJ014132.4-542749.9, turns out to be an extremely X-ray-weak blazar at high ...
An international team of astronomers has found that jets of 10 nearby active galactic nuclei (AGN) have changed their shape from parabolic to conical. The finding, reported in a paper published July 2 on the arXiv pre-print ...
Using NASA's Swift space telescope and NICER instrument aboard the International Space Station (ISS), astronomers have investigated the properties of an ultra-luminous X-ray pulsar known as NGC 300 ULX1. Results of this study, ...
Using very-long-baseline-interferometry (VLBI), an international team of astronomers has conducted a kinematic study of a jet of the blazar 4C+21.35. The research, presented in a paper published April 5 on the arXiv pre-print ...
Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, astronomers have detected a galaxy-wide molecular outflow from the quasar PDS 456. The findings are presented in a paper published March 25 on arXiv.org, ...
Using Russia's Spektr-R space telescope (also known as RadioAstron), astronomers have conducted high-resolution observations of the blazar S5 0716+71. The results of these observations, presented in a paper published February ...
Just over a decade ago scientists pushed magnesium atoms to new limits, jamming extra neutrons into their nuclei toward—and possibly reaching—the maximum limit for this element.
