very initial steps...

State College, Wednesday.

The afternoon seminar was by Mocioiu (Penn State) who talked about me favourite sub-atomic particle, neutrinos. The discussion was mainly focussed on what we've learnt about neutrinos over the last 10 years, and it seems, quite lot such as - non-zero masses, flavour switching, physics beyond the SM of PP (and this is even before taking cosmological results into account!). Now, instead of trying to understand neutrinos from the Sun, we are beginning to get in a position to understand the Sun from neutrinos (inner fusion processes etc.) She also talked about atmospheric neutrinos from *VERY* high energy cosmic rays (>10^9 Gev), and current experiments aiming to detect them. However, the bottom line of this (for me) was that no-one has yet to see a single very high energy neutrino from a cosmic ray and the most distantly detected neutrinos are still from 1987A...

Thursday a.m.
Spent most of the morning trying to write a potential introduction to, ahem, my next paper. Basically trying to motivate a cross-clustering analysis of LRGs and QSOs...

Thursday p.m.
Got a little bit side-tracked in doing a lit review for current/past papers on the Alcock-Paczynski effect, only to discover Bohdan Paczynski actually died earlier this year :-(

Worked a little bit more on my PSU TLT and am realising that this needs to be finished before I can start working on my LBNL talk!!
