The authors then estimate the average masses of the hidden supermassive black holes using the average properties of the broad ...
about systems at different scales. For example, in the traditional formulation of modified Newtonian dynamics (MOND), Newton’s second law is modified to boost the effect of gravitational forces once ...
The nearby starburst galaxy NGC 253 has been experiencing enhanced star formation for the past few tens of millions of years, mostly in massive young star clusters embedded near t ...
Editor’s Note: Astrobites is a graduate-student-run organization that digests astrophysical literature for undergraduate students. As part of the partnership between the AAS and astrobites, we ...
NASA’s JWST has found a population of compact, red light sources called “little red dots” (LRDs). Numerous hypotheses have ...
Weller and collaborators utilized ASTRID, a high-resolution cosmological simulation that includes a sophisticated prescription for seeding and evolving black holes. Unlike in some other cosmological ...
In total, the complete database contains information about 10,259 star clusters and stellar associations and their individual members. The authors identified more than 11,000 new candidate cluster and ...
Need a place to publish works in progress, comments and clarifications, null results, or timely reports of observations in astronomy and astrophysics? RNAAS is open for submissions. The American ...
The 58th meeting of the AAS Division for Planetary Sciences will take place 25–30 October 2026 in Spokane, WA. Register today! The American Astronomical Society (AAS) is the major organization of ...
Now, the team has obtained new photometry from the Gran Telescopio Canarias and the United Kingdom Infra-Red Telescope, plus spectroscopy from the Gran Telescopio Canarias, to get a better sense of ...
It turns out that the fate of a binary system depends on whether it is dynamically “hard” or “soft.” Hard binaries are generally tightly bound, and they tend to get “harder” from stellar flybys, which ...
