[ArXiv]4th week, Mar. 2008

The numbers of astro-ph preprints on average have been decreased so as my hours of reading abstracts…. cool!!! By the way, there is a paper about solar cycle, PCA, ICA, and Lomb-Scargle periodogram.

  • [astro-ph:0803.3154]B. G. Elmegreen
    The Stellar Initial Mass Function in 2007: A Year for Discovering Variations

  • [astro-ph:0803.3260]J.K. Lawrence, A.C. Cadavid & A. Ruzmaikin
    Rotational quasi periodicities and the Sun – heliosphere connection (I wish arxiv provides keywords. My keywords to this preprint are solar cycle, Lomb-Scargle periodogram, PCA, ICA, all interesting to CHASC folks. Particularly, I felt some similarity to one of stat310 talks about Gravity Probe B)

  • [astro-ph:0803.3775] L. Samushia, & B. Ratra
    Constraints on Dark Energy from Galaxy Cluster Gas Mass Fraction versus Redshift data (another example of Monte Carlo Markov Chain, not Markov chain Monte Carlo in the abstract but MCMC is not their research focus)
