Today’s paper makes predictions for the yet-to-be-observed dwarf galaxy population around Andromeda’s satellite galaxy, M33. It provides scientific justification for a future mission with WFIRST.
Could intermediate-mass black hole activity resolve the long-standing problems with dwarf galaxies in cosmological simulations?
We report on Day 3 of the winter AAS meeting in Seattle, WA. Highlights include updates in X-ray astronomy, the discovery of a second repeating FRB, an exploration of astrochemistry in planet-forming disks, and a look at the 2020 Astronomy Decadal Survey.
Scientists can use neural networks to glimpse gravitational wave fluctuations from the early universe.
Is string theory compatible with observational data? Today’s paper looks at how avoiding the swampland of unsuccessful string theories can mean violating reliable constraints on cosmological quantities.
Neutron star black hole mergers are an ideal way to measure the Hubble constant.
