SUMMARY:A Novel Lya Forest Statistic and Constraints on the IGM - Khee-Gan

DESCRIPTION:The Lyman-alpha Forest is an important probe of the inter-gala
 ctic medium (IGM)\, which comprises >90% of baryons at high redshifts and 
 is the reservoir for galaxy formation. At z<3\, HeII reionization is predi
 cted to be the dominant process in regulating the properties of the IGM. I
  will introduce a new statistic\, the threshold clustering functions\, whi
 ch can detect thermal inhomogeneities from HeII reionization when applied 
 to SDSS data. I will also discuss some of the systematics involved\, and q
 uantify the ability of this statistic to distinguish between different toy
  models of the IGM.
