The Mysterious Pulsars That Switch On and Off
Pulsars emit radio radiation, but sometimes they just randomly switch off. Why is that?
A Second Mysterious Radio Outburst from Magnetar XTE J1810-197
Why is one magnetar giving off bursts of energetic radio waves? Is it related to giant pulses? FRBs? Both?
Moonetesimals likely form relatively quickly
The absence of dusty circumplanetary disks around young giant planets suggests moonetesimals grow relatively quickly.
Radio Pulsars: How Slow Do They Go?
The discovery of the slowest rotating radio pulsar, PSR J0250+5854, has scientists wondering – how slow do radio pulsars spin?
When the Sky Isn’t the Limit: Simulations of Imaging a Black Hole from Space
Recently, the world saw the first-ever images of a black hole’s shadow. Future images could be sharper with space-based telescopes!
Testing Einstein’s Equivalence Principle by Timing a Pulsar in a Stellar Triple System
PSR J0337+1715, a millisecond pulsar in a hierarchical stellar triple system with two white dwarfs, provides a stringent test of gravity via Einstein’s strong equivalence principle!
