PHY2030 Observing the Universe 2017-18
Dr S. Hinkley
 
Delivery Weeks: T2:01-11
Level: 5 (NQF)
Credits: 15 NICATS / 7.5 ECTS
Enrolment: 84 students (approx)

Description

In this module students will gain a basic knowledge of the universe and its contents, and good understanding of astrophysical measurement. As such it is crucial for the astrophysics project work, and when combined with the detailed understanding of stars, galaxies and cosmology obtained from the subsequent modules, PHY3063, PHY3066 and PHYM006, will provide a well-balanced grounding in astrophysics.

The specific aims of the module are to impart: a basic knowledge of the hierarchy of objects in the universe, including their structural and evolutionary relationship to each other; an understanding the underlying principles of key instrumentation used for observational astrophysics; an understanding of how we can obtain structural information and physical parameters from distant, often unresolved, objects.

Module Aims

This module pre-dates the current template; refer to the description above and the following ILO sections.
