What exactly are Baryon acoustic oscillations? How do we detect them? How are they used to build a "ruler" of cosmological parameters? How are BAOs related to the late time ISW effect? and to dark energy?
Lots of questions, hopefully someone here can give me some answers or at least some comment on ths interesting stuff that brings together data from CMB power spectrum and optical surveys like SDSS or spectroscopical like the LRGs.
Thanks
