Major Option C1 AstrophysicsC1 AstrophysicsCourse co- ordinator: Julien Devriendt [email protected] C1 offers a total of 40 lectures on five themes covering abroad range of topics in contemporary astrophysics. Each theme takes off from the third- year courses andreaches a point where topics of current active researchcan be understood. The course uses special relativity, classical mechanicsand GR, electrodynamics, quantum mechanics andstatistical mechanics.Oxford Astrophysics

Major Option C1 AstrophysicsRadiative Processes in AstrophysicsThe Eagle Nebula star- forming region as seen by HSTOxford Astrophysics
Major Option C1 AstrophysicsIn radiative processes part of the course, we learn many of the coretechniques of professional astronomy – how to turn all those pretty picturesinto physics!We learn how to use spectroscopy to measure the extreme physicalproperties of material in deep interstellar space – high temperatures and lowdensities. Transitions forbidden under normal lab conditions often play acrucial role.We learn how emission and absorption lines are formed in stars and nebulaeand how interstellar dust affects the observed spectrum of backgroundobjects – and how to correct for it.Finally we use relativity, electrodynamics and statistical mechanics toinvestigate the interaction of photons with high- energy particles viasynchrotron, inverse- Compton and Bremsstrahlung processes .Oxford Astrophysics

Major Option C1 AstrophysicsIn high- energy astrophysics we study some of the most extreme phenomenain the Universe – active galaxy jets, supernovae, accretion onto black holes,and the high- temperature intergalactic medium.We study the fluid dynamics of strong shocks to investigate the accelerationof particles to relativistic energies.We investigate the physics of relativistic jets from accreting black holes andtheir profound influence on the formation of galaxies over cosmic time, andthe interaction between intergalactic gas and the Cosmic MicrowaveBackground, which in turn allows us to measure some of the cosmologicalparameters.Finally we study the detection of high- energy particles and photons from theground via Cherenkov radiation.Oxford Astrophysics
Major Option C1 AstrophysicsAdvanced Stellar AstrophysicsLeft: Rings around supernova 1987A observed by HST. Right: model of the ring nebula demonstratingthat the progenitor of SN1987A was likely a massive binary system in a common envelope.Oxford Astrophysics
Major Option C1 AstrophysicsIn advanced stellar astrophysics we study the evolution of massive stars andsupernovae, including gamma- ray bursts and hypernovae.We examine compact objects resulting from supernovae – neutron stars,pulsars and stellar- mass black holes – and consider accretion onto compactobjects in binary systems.Finally we study the early stages of stellar evolution – star (and planet)formation from interstellar clouds and we consider the formation of the firstgenerations of stars in the universe.Oxford Astrophysics
Major Option C1 AstrophysicsCosmology and GalaxiesOxford Astrophysics
Major Option C1 AstrophysicsThe section on Cosmology and Galaxies builds on B5 General Relativity &Cosmology. We take the expanding universe Friedmann models &investigate the amplification of density fluctuations as the universe grows.These growing fluctuations are the seeds for modern day structure fromgalaxies to superclusters and encode information about the ingredients of theuniverse – baryons, dark matter and dark energy.We study how observations of the Cosmic Microwave Background andredshift surveys of galaxies may be used to measure the relative proportionsof these componentsUsing stellar population synthesis models, stellar dynamics and gravitationallensing we study the evolution of galaxy properties throughout cosmic ages,their dependence on environment and build up evidence for the existence ofdark matter.Oxford Astrophysics

Astrophysics needs input of practically all sub-disciplines of physics and thus a course on astrophysics cannot be self-contained. However, the course should be accessible to students with just a general introduction to physics. Few sections of the text that are somewhat more advanced and that can be omitted are marked by stars. I will be glad to receive feedback from the readers of these .

Theme 7: Astrophysics The situation at the end of the 19th century can be pictured by reading Agnes Clerke’s authoritative Popular History of Astronomy During the Nineteenth Century. There was much factual knowledge, and a start on classification, but very little understanding. Sir Norman Lockyer (1836 1920) had begun to argue, based on observations of solar and stellar spectra, that .

Candidates may attempt either or both Parts. The number of marks for each question is the same, with Part (ii) of each question carrying twice as many marks as Part (i). The approximate number of marks allocated to each component of a .
DEPARTMENT OF ASTROPHYSICS INTRODUCTION The University Observatory, also known as the Department of Astronomy, was designed by architect Charles Barry. Located in the University Parks, it was built in 1873-5 to house a school of astronomical physics, the main focus of which would be research. Howard Grubb, astronomical instrument maker, was commissioned by the University to build a 12.25 inch .
