An international team of astronomers has performed a comprehensive, multiwavelength study of a blazar known as 1ES 1218+304. Results of the research, presented in a paper published January 3 on the arXiv preprint server, ...
Using NASA's Fermi spacecraft, Chinese astronomers have investigated the variability and spectral behavior of gamma-ray flares in a distant blazar known as 3C 279. Results of the study, presented in a paper published in the ...
Astronomers from Argentina and France have investigated the evolutionary history of an eccentric high-mass X-ray binary known as GX 301-2. Results of the study, published December 22 on the arXiv pre-print repository, deliver ...
Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has inspected the recent outburst of an accreting millisecond X-ray pulsar known ...
By analyzing the data from NASA's Swift spacecraft and from the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station, astronomers have investigated an active optical transient known as ...
How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including ...
