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 ...

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 ...

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 ...

The jet-like appearance arises when this arrangement is viewed from the side; the team created synthetic images of their simulated spicules that show individual jet-like features. These “jets” have ...

This apparent paradox comes from the different nature of cold and warm clouds. Cold clouds are denser and more compact, occupying much smaller physical scales than warm clouds. So to match the length ...

While it’s common to find millisecond pulsars in binary systems — in fact, many millisecond pulsars are thought to spin up to their incredible speeds via accretion from a stellar companion — it’s rare ...

Join us in Salt Lake City, UT, 10–14 January 2027 for exceptional science at the 249th meeting of the American Astronomical Society. Register today! The American Astronomical Society (AAS) is the ...

S250818k offered a rare opportunity to associate the light from a kilonova with a gravitational wave detection, a feat achieved only once so far, in 2017. The intrigue surrounding S250818k was ...
