(Not) Detecting Planets around Brown Dwarfs with Radio Waves
Forbich, Berger, and Reid attempt to use a large radio array to detect stellar wobbles induced by orbiting planets at larger separations than are usually probed
The Habitability of Exomoons
The search for exoplanets in their habitable zones continues. But exomoons could be habitable, too! This paper models hypothetical exomoons in four real systems to determine the habitability of moons around planets that don’t necessarily stay in the habitable zone.
Lensing B-modes in the Cosmic Microwave Background polarization
Gravitational lensing causes distortions in the polarization of the Cosmic Microwave Background. In this astrobite, we discuss recent results from the South Pole Telescope collaboration measuring patterns caused by lensing in the CMB polarization. What do these patterns tell us about the Universe?
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.
Nature versus nurture in the growth of galaxies
Galaxies have more than doubled in size since they first formed, but why?
Astrophysical Classics: Neutral Hydrogen in the Universe, Part 2
Gas in the Universe went from being mostly neutral to mostly ionized as the first galaxies formed, and the signature of this process is imprinted in quasar spectra. The review of the classic paper by Gunn & Peterson continues in this second in the three-part series.
