    One of the interesting things about this paper, is that they have a modular code, StringFast which they release here: http://www.astro.ubc.ca/people/scott/stringfast.html

    Nice to see our (Morganson et al, ref 17) lensing limit on the string tension (from not finding any sets of split pairs of faint blue galaxy images in the HST archive) is still competitive - its equal to the CMB limit they take as their best case scenario :-) Mind you, we could only rule out long straight strings.We could probably put some limit on their wiggliness parametr too I suppose - but its nice that the CMB power doesn't care about wiggliness or anything.

    Another paper looking at constraining allowed models for the primordial power spectrum (in this case the potential).
