Astronomy & Astrophysics at Macquarie

1. Astronomy & Astrophysics at Macquarie • Physics can be an exciting and dynamic field of study • Astronomy and astrophysics courses have been designed to offer an interesting and diverse range of topics which start with fundamental concepts and background material and finish with a detailed description of astrophysical phenomena and the underlying physics. Feb 22rd 2010

2. Faculty Astronomers at Macquarie • Prof. Quentin Parker Is director of the astronomy CORE. Research activities are mainly but not exclusively associated with Wide Field Astronomy and narrow-band surveys and the Macquarie/AAO/Strasbourg H-alpha Catalogue of Galactic Planetary Nebulae (MASH) of which he is head. • Prof. Mark Wardle Theoretical investigations of interstellar clouds including supernova remnants, shock waves, masers, star formation, protoplanetary discs and the Galactic Centre. Collaborations here and in the USA on interpretation of radio/sub-mm/ir/optical(HST)/x-ray(Chandra) observations of the Galactic Centre, SNRs, molecular clouds and star-forming regions. • A/Prof Orsola De Marco Research activities are mainly focussed on the role of binary stars in the shaping and evolution of Planetary Nebulae and on the theoretical aspects of binary interactions. • Dr Dan Zucker • Dr Jon Lawrence & Dr. Alan Vaughan Feb 22rd 2010

3. ASTR170 – ASTRONOMYProf. Quentin Parker & Dr. Dan Zucker • This is a general-education unit of study which is offered internally every year . It is usually taken in 2nd year except for those entering the astronomy stream when they are encouraged to undertake the subject in first year. It gives a broad introduction to the field and includes: • some basic mechanics and optics; • historical development of astronomical instruments and techniques across the whole electromagnetic spectrum; • celestial coordinate systems & navigation; • Stars, galaxies, nebulae, quasars, pulsars, black holes; • evolutionary models and alternatives; • basic cosmology. • Experimental lab work may be chosen from such topics as geometrical and physical optics, spectra, photography, galaxy classification, use of an optical telescope and a simple radio telescope • Some practical sessions will be spent at the Division's observatory (evenings).

4. MACQUARIE UNIVERSITY, DEPARTMENT OF PHYSICS RESEARCH – ASTRONOMY & ASTROPHYSICS CORE Astronomy and astrophysics research has grown rapidly at Macquarie over the last 6 years. There are now ~30 group members including 5 academic staff, 4 associates, 4 postdoctoral fellows, 10 PhD students, 4 masters students and various honours students engaged in a vigorous program of diverse research: See http://www.physics.mq.edu.au/astronomy/ Macquarie astronomers have built a strong international reputation. Current research strengths include wide-field astronomy, optical, infrared and radio studies of planetary nebulae and supernova remnants, stellar proper motions, and theoretical studies of shock-waves, star formation and black holes. Our deep LMC Hα stack image SMP27 HST image of LMC planetary nebula SMP27 Output metrics 2003-2008: Publications:150+ papers including 60+ in refereed journals; Major Grants with a total value ~$3m; Major telescope access won on world’s most prestigious observatories such as HST, SPITZER, CHANDRA, GEMINI, ESO VLT) equivalent to $4.2m of facility access; 5 PhD completions since Dec 2005 – most go in to industry.

Image is 120 by 48 arcmin This 400 by 900 light-year mosaic of several Chandra images of the central region of our Milky Way galaxy reveals hundreds of white dwarf stars, neutron stars, and black holes bathed in an incandescent fog of multimillion-degree gas. The supermassive black hole at the center of the Galaxy is located inside the bright white patch in the center of the image. The colors indicate X-ray energy bands - red (low), green (medium), and blue (high). Feb 22rd 2010

16. ASTR178 Other Worlds: Planets and Planetary Systems • Semester 2 1st year course 3cp (People & Planet unit) • This unit explores our solar system and the newly-found planetary systems around other suns. • We examine the processes that have shaped the marvelous variety of worlds within our own solar system, from the scorched and buckled surface of Mercury to the geysers of frozen methane on Neptune's largest moon, Triton. • From this we build an understanding of how our solar system formed and subsequently evolved to become the system that we inhabit today. • We look at the discovery of a startling variety of planets around other stars. • These provide a new and challenging perspective on our place in the Universe that is modifying the scientific theories of how generic planetary systems are formed. The unit will highlight breaking news as the unit proceeds. • The practical component of the unit includes observing the planets with the telescopes of the Macquarie University Observatory. • Prerequisites and Corequisites: NONE!! • Lecturers: De Marco, Parker, (Gilchrist) Feb 22rd 2010
