Two weeks in review (October 27-November 9)
Evidently I forgot to post one of these roundups last week, so here’s two weeks’ worth of writing all at once! Also, I have a new sticker design you can order, for those of you (like me) who don’t willingly run for exercise, but want to feel you’ve accomplished something anyway. At least in a…

The Solar System boundary and the week in review (September 8-14)
‘Twas a busy week! High-resolution observations show how black hole jets churn galactic gas (Ars Technica): One portion of my PhD thesis involved galactic feedback. That’s the process by which jets from black holes at the center of galaxies push material away, potentially affecting star formation and other activity. This article addressed the observation of…

Much ado about nothing in today’s dark matter non-announcement
OK, I might be feeling a little cranky about this, but my article for Ars Technica is a little more measured. I’ll have a longer analysis for Galileo’s Pendulum tomorrow, for those who want it. The short version: the Alpha Magnetic Spectrometer (AMS-02) is a particle detector installed on the International Space Station. For several…

Planck: news from the infant Universe
For cosmology-lovers like me, yesterday was a full, busy day. The Planck telescope released its first full set of data, refining the estimates of the age of the Universe and its contents. I wrote two big pieces, one for Ars Technica and one for Galileo’s Pendulum. First Planck results: the Universe is still weird and…

Will we ever know the identity of dark matter?
Forgive me if I get excited for a moment, but…today marks my first contribution to BBC Future! The feature I contributed is part of the “Will we ever?” series, in which science writers ask some big questions about what research may or may not be able to answer in the future. My article pondered whether…

“A” is for axion
Originally posted on Galileo's Pendulum: Wot’s all this, now? Today I begin a new feature, which I will try to update once a week: the Alphabet of Cosmology. In these entries, I’ll highlight a concept, experiment, or observation in cosmology—the study of the history, contents, and evolution of the Universe—that may not be as…
