ASAS-SN searches for supernova and finds variable stars too! They found so many (~90,000) that they decided to classify them all. How do you go about classifying 90,000 things? Machine learning, of course!
The Hubble constant describes the rate at which the universe expands. But different measurements of it yield different results – a problem for the cosmic standard model. Today’s paper discusses new Cepheid observations, which increase the problem – so, are we on the brink of new physics?
Supernovae may be among the most powerful events in the cosmos, but astronomers think that companion stars may be able to survive these intense explosions.
Today’s astrobite explores a newly detected triple AGN system.
The surprising result of a search for radio AGN in nearby dwarf galaxies
A neural network enables transient classification with ongoing observations, potentially providing astronomers with more time to study the transient while it is still occurring.
