Enigmatic Explosions: How Different Supernova Models Yield Very Different Galaxies
Accounting for the uncertainty in supernova explosion parameters can substantially change the star formation history and morphology of galaxy simulations.
Using a Random Forest to Classify ASAS-SN Variable Stars
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!
Do we need to expand the cosmological standard model? New cepheid observations suggest yes
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?
Searching for Supernova Survivors
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.
A Discovery of a Triple AGN System
Today’s astrobite explores a newly detected triple AGN system.
Not all Black Holes that Wander are Lost
The surprising result of a search for radio AGN in nearby dwarf galaxies
