Dust in SPACE: Studying the growth of planetesimals with a suborbital rocket experiment

By sending a chamber of dust on a suborbital ballistic rocket, the authors of this paper hope to find out how planetesimals form.

AR Coating with a Silicon Dicing Saw

Anti-reflection coatings aren’t just for your glasses — telescope lenses need them too! Here we look at a new technique for reducing reflections in lenses made of silicon.

What Can Radio Emission Tell Us About Dark Matter?

Dark matter particles annihilating could potentially create electrons and positrons, generating continuum synchrotron emission. This paper attempts to find this signature in nearby dwarf galaxies.

Cosmic Rays from the Telescope Array

An array of cosmic ray telescopes in western Utah is determining the origin of the most energetic particles in the Universe.

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.

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 2: Touchdown Pole!

I’m spending a month working on a telescope at the South Pole. In this post, I travel from New Zealand to the Pole in a ski-equipped military plane!

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!
