For the purposes of considering request for Reasonable Adjustments under the Disability Standards for Education (Cwth 2005), and Student Support and Engagement Policy, academic requirements for this subject are articulated in the Subject Overview, Learning Outcomes, Assessment and Generic Skills sections of this entry.

It is University policy to take all reasonable steps to minimise the impact of disability upon academic study, and reasonable adjustments will be made to enhance a student's participation in the University's programs. Students who feel their disability may impact on meeting the requirements of this subject are encouraged to discuss this matter with a Faculty Student Adviser and Student Equity and Disability Support: http://services.unimelb.edu.au/disability

This subject provides an advanced introduction to physical cosmology. Specific topics may include the isotropic homogeneous Universe, the Robertson Walker metric, the Friedmann equations, baryogenesis, inflation, big-bang nucleosynthesis, the recombination era, density fluctuations as the origin of galaxies, the cosmic microwave background, linear and non-linear growth of structure, the Press-Schechter mass function, reionization of the IGM and gravitational lensing. Examples are drawn from past and current cosmological observations.

The objectives of this subject are:

• to challenge the students to develop knowledge of fundamental physical principles governing the formation and evolution of structure in the Universe;
• to understand the connection between the microscopic properties of particles and the macroscopic evolution of the Universe;
• to introduce students to the problems facing contemporary research in cosmology;
• to appreciate the distinction between the evolution of baryonic and non-baryonic matter;
• to develop the skills required to interpret cosmological data.

Four assignments totalling up to 48 pages (40%), evenly spaced throughout the semester, plus one end-of-semester 45-minute oral examination or one end-of-semester 3-hour written examination (60%)

This subject is not available as a breadth subject.

At the completion of this subject, students should have gained skills in:

• analysing how to solve a problem by applying simple fundamental laws to more complicated situations;
• applying abstract concepts to real-world situations;
• solving relatively complicated problems using approximations;
• participating as an effective member of a group in discussions and collaborative assignments;
• managing time effectively in order to be prepared for group discussions and undertake the assignments and exam.
