Designing a Self-Steering Spacecraft
As we push spacecraft to the edges of our solar system and beyond, it gets harder and harder to navigate them from Earth. But what if spacecraft could steer themselves, using observations of pulsars? Read on to find out how!
Closing In on the Epoch of Reionization
An array of dipole antennas in South Africa’s Karoo desert offers the best limit on the power spectrum of the Epoch of Reionization.
Astrobites on the Ice, Part 5: South Pole Station
I’m spending a month at the South Pole working on a CMB telescope. In this last post, we tour South Pole Station and run a race around the world!
Astrobites on the Ice, Part 4: A Day in the Life
I’m spending a month at the South Pole working on a CMB telescope. In this installment, I measure the telescope’s sidelobes and close up a receiver.
The search for WIMP annihilation in the Sun
The quest for identifying the dark matter particle is well underway. Today, we discuss the work of the ANTARES collaboration, which is using a neutrino telescope to search for signals of dark matter annihilation in the Sun.
Astrobites on the Ice, Part 3: A Tour of DSL and MAPO
I’m spending a month working on a telescope at the South Pole. In this post, we take a tour of the two observatory buildings hosting Cosmic Microwave Background experiments.
Astrobites on the Ice, Part 1: Halfway to Pole
I’m spending the next month working on a telescope at the South Pole. In this first installment, I check out New Zealand and get my Extreme Cold Weather gear!
How to use DNA to search for dark matter
Can DNA be used to detect dark matter? Guest author Elisa Chisari explains how biology and physics can combine to teach us more about the universe.
Polarization in Stacked X-ray Imaging Detectors
Why are there so few X-ray imaging polarimeters? This paper determines the intrinsic sensitivity of stacked imaging detectors to hard X-ray polarization.
The FORCAST Camera on SOFIA
A new infrared camera is now flying 41,000 feet above the Earth’s surface!
