Using a normalizing flow emulator, researchers predict the gravitational wave strain distribution due to supermassive black hole binaries; this method outperforms Gaussian process methods.
The current orbit of Mars’s larger and closer-in moon, Phobos, is consistent with either formation in the early solar system and inward migration, or production in an ongoing ring–moon cycle.
High-resolution imagery, thermal observations, topographic, geological, and mineralogical analyses suggest that a previously identified cave candidate is connected to the subsurface cave environment.
Stellar-mass black holes may become ensnared in gravitational traps in the disks around accreting black holes, but simulations show how binary black holes may be able to escape or remove the traps.
A newly discovered pulsar exhibits both persistent dim pulses as well as sporadic bright pulses similar to what is seen from rotating radio transients.
An analysis of coronal mass ejections during solar cycles 23 and 24 shows that the mass-loss rate of these events changes with the solar cycle, with certain latitudinal dependencies also present.
