Light, delayed: The Shapiro Effect and the Newtonian Limit
Markus Pössel
The Shapiro effect, also known as the gravitational time delay, is close kin to the gravitational deflection of light that was the central topic of our Summer School. It is also an…
Interpretations of cosmic expansion: anchoring conceptions and misconceptions
Markus Pössel
Teaching cosmology at the undergraduate or high school level requires simplifications and analogies, and inevitably brings the teacher into contact with at least one of the pedagog…
Deriving the Schwarzschild solution from a local Newtonian limit
Markus Pössel
The Schwarzschild metric is derived in a manner that does not require familiarity with the formalism of differential geometry beyond the ability to interpret a general spacetime me…
The Shapiro time delay and the equivalence principle
Markus Pössel
The gravitational time delay of light, also called the Shapiro time delay, is one of the four classical tests of Einstein's theory of general relativity. This article derives the N…
A Beginner's Guide to Working with Astronomical Data
Markus Pössel
This elementary review covers the basics of working with astronomical data, notably with images, spectra and higher-level (catalog) data. The basic concepts and tools are presented…
Relatively complicated? Using models to teach general relativity at different levels
Markus Pössel
This review presents an overview of various kinds of models -- physical, abstract, mathematical, visual -- that can be used to present the concepts and applications of Einstein's g…
