To mark the 243rd American Astronomical Society meeting, Physical Review Letters, Physical Review C, and Physical Review D highlighted several significant papers in astrophysics to illustrate the type of research these journals seek to publish.
Researchers have found new evidence that high-energy neutrinos are emitted when a black hole gobbles up a hapless star.
Using cross-correlation measurements and an updated cosmic-microwave-background lensing map, researchers determine cosmological parameters with greater precision.
A space-based observatory will detect gravitational waves from so many different types of sources at once that a global approach will be needed to crunch the data.
Simultaneously detecting the gravitational-wave and neutrino signals emitted during the last second of a massive star’s life could show how such stars die.
Neutrino fast flavor conversion (FFC) typically occurs in extremely dense neutrino environments such as those of core-collapse supernovae (CCNe). The typical distance and time scales at which FFCs take place are much smaller than those accessible to hydrodynamic simulations of CCSNe. In this paper, FFCs are schematically taken into account in spherically symmetric CCSN hydrodynamic simulations and their distinctive effects are delineated.
Interstellar magnetic fields perturb the trajectories of cosmic rays, making it difficult to identify their sources. A new survey of gamma radiation produced when cosmic rays interact with the interstellar medium should help in this identification.
If ultralight dark matter particles exist, they can contribute no more than 70% of the dark matter between Earth and a set of monitored pulsars.
Supercomputer simulations of the weather on a hot Jupiter reveal a previously unseen storm pattern in which cyclones are repeatedly generated and destroyed.
