Module Aims and Objectives:

This module is a distance learning unit for the University Certificate in Cosmology and is a core module for the Cert HE in Astronomy. It provides a broad introduction to modern cosmology.

It will provide students with:

1.    educational material to allow them to logically assimilate information about ideas and concepts in modern cosmology.

2.    the background to current developments in the subject area and an awareness of why it is important to continue with future research.

3.    an awareness of how cosmology (through astronomical observations) can be used to probe and test the extremes and uncertainties of physics.

4.    information that will stimulate further their interest in cosmology and astrophysics.

Syllabus and Content:

THE BIG BANG - THE SECOND ERA

·       the hot big bang model - the “standard model”

·       expansion --> cooling

·       hot particles and radiation

·       what happened to antimatter

·       protons and neutrons form

·       atomic nuclei form

·       atoms form - recombination

·       decoupling - cosmic background radiation

BEFORE THE BIG BANG - THE FIRST ERA

·       inflation

·       theory + speculation

·       why the big bang was hot

·       why the universe expands

·       total energy = zero ?

·       solving the horizon and flatness problems

·       cosmology <--> particle physics

AFTER THE BIG BANG - THE THIRD ERA

·       steady expansion, astrophysics

·       the meaning of expansion

·       distance becomes harder to define

·       Einstein’s equations

·       redshift

·       horizons

·       the Cosmic Background Radiation (CBR)

·       observational evidence for expansion

·       Hubble

·       Tolman test (1991)

·       CBR hotter in the past

·       absorption lines

·       Hubble’s constant

·       galaxy formation

·       epoch of formation

·       dark matter

·       Hubble Space Telescope images, Keck results.

·       open or closed

·       exciting research topics

Teaching and Learning Strategy:

Students will learn via self-study, supported by detailed distance learning material supplied by the Department according to a Course Schedule. Each student will receive Course Notes and a Workbook. The Course Notes, which are closely linked to a course textbook, will be based on how we use observations, coupled to basic physical principles, to understand the phenomena of the Universe. The Workbook contains the assessed coursework and self-test exercises. Additional material will be available via the Course Website to supplement the examples given in the Workbook. The website will contain topical information on popular articles related the material in the course and some of the assignments will contain questions to encourage students to broaden their awareness of different sources of information including traditional libraries and the internet.

Tutorial support will provided by e-mail, electronic discussion groups and telephone.

Learning outcomes:

Students will be able to demonstrate:

·      a broad understanding of the subject of cosmology which may form a basis for further studies in astronomy, astrophysics and related sciences

·      elementary problem solving skills

·      the ability to summarise scientific information and concepts

·      the ability to research a scientific topic.

Assessment Strategy:

The module assessment is by coursework only and there is no examination.

There are three equally weighted items of coursework normally consisting of two question sheets and one essay of about 1000 - 1500 words. There is no requirement to pass each of the assessment individually provided that the essay is attempted and the overall module mark is 40% or more.
