... As these data span a large range in redshift, they are ideal for testing the validity of Type Ia supernova progenitor models with the distribution of expected \delay times," from progenitor star formation to SN Ia explosion, and the SN rates these models predict. Through a Bayesian maximum likelihood test, we determine which delay- time models best reproduce the redshift distribution of SNe Ia discovered in this survey. ... 1998) SD model. ... We tested two Gaussian delay time distribution models. ...

This course will deal with the issues of how to acquire and analyze data for the purpose of transforming emotional debates on environmental problems into objective ones. ... In other words, this course is about how you shape environmental debate/policy around real data nd how ultimately, policy is limited by the reliability and availability of relevant data. ... Since the course material is always available, there is no longer a need for students to incessantly take notes in class. ...
