The authors then estimate the average masses of the hidden supermassive black holes using the average properties of the broad ...

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 ...

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 ...

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 ...

A number of different mechanisms predict that during this process, the protoplanet should emit light at a certain frequency associated with electrons jumping between energy levels in hydrogen atoms — ...

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 ...

Redshift distribution: The median redshift for this sample is z = 3.3, which is higher than that of less luminous galaxies, suggesting that brighter submillimeter galaxies are found at higher ...

Enormous, cool stars like Betelgeuse can inform studies of stellar evolution, supernovae, gravitational waves, and more! Dr. Emily Levesque reveals what we can learn from red supergiants in her new ...

The distribution of gas within the disk, traced by emission from carbon monoxide, roughly follows the pattern seen in previous observations of small dust grains: the orbits of WISPIT 2b and 2c are ...

The authors focus on small regions on the very edge of the supernova shock front, six northern and eight southern, to carefully measure the motion of the shock between the two sets of observations. In ...

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 ...
