ALFALFA is a blind survey using the Arecibo telescope designed to detect neutral hydrogen in other galaxies. A brief overview of the survey is available in the About page. If that’s not nearly enough information for you, don’t worry! Future posts will describe various aspects of the survey, data, and follow-up observations in detail. Another goal of this blog is to share the excitement (and trials) of ALFALFA, including observing reports and summaries of new science and papers as they’re published.

We’d also love to hear from you. Do you have a general question about ALFALFA that you would like answered? Post it in the comment section of this entry, and we’ll do our best to answer it.
