Selections from 2019: Neutrinos and Gravitational Waves from Cosmic Catastrophes
Some astrophysical sources should produce both neutrinos and gravitational waves. What have we learned looking for this simultaneous signal?

An Extreme Pulsar Seen in Gamma Rays
One of the fastest spinning radio pulsars known has now been detected to pulse in gamma rays, too.
Mass-ive Implications for Exoplanetary Atmospheres
To study the atmosphere of an exoplanet, it turns out we need to have a solid handle on its mass.
When A Black Hole (Partially) Destroys a Star
A new study explores what happens when a passing star has a close encounter with a supermassive black hole — and lives to tell the tale.
Climates of Distant Terrestrial Worlds
What determines the climate of an Earth-like planet orbiting its host star? A new study explores how distant worlds are shaped by their hosts.
The Appearance of a Black Hole’s Shadow
What determines the size and shape of the shadow of a black hole?
Fantastically Fast Transients and How They Happen
What caused the appearance of the fast transient SN2018kzr? A very interesting sort of neutron star may be involved.
Where’s the (Magnetic) Flux?
What’s to be done when theory and observation don’t match? A recent study may have found a missing piece in our models of the Sun’s magnetic field.
Smashing Planets to Build Giants
How do you get close-in, giant planets on eccentric orbits? A new study suggests that a violent phase of planet-smashing might be a key part of the process.
Hunting for a Dark Matter Wake
As the Large Magellanic Cloud plows through the Milky Way’s dark matter halo, it may leave telltale signs of its passage.
