A new study published in Nature Astronomy indicates that the dense, star- and dark-matter–rich environments around supermassive black hole binaries pack on the order of a million solar masses into each cubic parsec. The ...
By analyzing the data from various space observatories and ground-based telescopes, European astronomers have performed a multiwavelength study of a bright gamma-ray blazar known as S5 1044+71. The new study, published Feb. ...
Italian astronomers have performed extensive spectroscopic monitoring of a recently discovered nova known as Vulpeculae 2024, also known as V615 Vul. Results of the new observations, presented in a paper published in the ...
Astronomers have analyzed the images collected by the Hubble Space Telescope (HST) to investigate a galactic open cluster known as NGC 2158. Results of the study, published Feb. 25 on the arXiv pre-print server, provide essential ...
When the densest objects in the universe collide and merge, the violence sets off ripples, in the form of gravitational waves, that reverberate across space and time, over hundreds of millions and even billions of years. ...
