Why SKA hear at Study in Australia – itsReal

Over the past several years, discussions have been occurring in several countries about the next logical step in radio astronomy following the construction of the large millimetre array ALMA. An initiative has emerged to develop a telescope to provide two orders of magnitude increase in sensitivity over existing facilities at metre to centimetre wavelengths. To achieve this goal will require a telescope with one square kilometre of collecting area – one hundred times more collecting area than the Very Large Array (VLA).

The Square Kilometre Array (SKA) will probe the gaseous component of the early Universe, thereby addressing fundamental questions in research on the origin and evolution of the Universe. The SKA will complement planned facilities at other wavelengths, such as ALMA and James Webb Space Telescope (JWST). HI, CO and continuum radiation would be observed from the interstellar medium of most of the galaxies the JWST will discover in the infrared at large redshifts.

Extensive discussion of the science drivers and of the evolving technical possibilities has led to a concept for the Square Kilometre Array and a set of design goals. The SKA will be an interferometric array of individual antenna stations, synthesizing an aperture with diameter of up to several 1000 kilometers. A number of configurations are under consideration to distribute the 1 million square metres of collecting area. These include 30 stations each with the collecting area equivalent to a 200 metres diameter telescope, and 150 stations each with the collecting area of a 90 m telescope ( more about design and location proposals ).

Approximately 50% of the collecting area is to be contained within a centrally-condensed inner array of 5km diameter to provide ultrahigh brightness sensitivity at arc-second scale resolution for studies of the faint spectral line signatures of structures in the early Universe. Another 25 % of the collecting area will be located within a diameter of 150 km, and the remainder out to 3000 km or more. This high angular resolution capability will allow imaging of faint emission from the interstellar medium of distant galaxies, as well as the surface of stars, and the active nuclei of galaxies.

Top Five Principal Science Drivers for SKA Project

Perth Education City is proud to present Professor Peter Quinn for a special seminar at the Australian Education Showcase 2009 on the cosmic journey back in time – the findings, the mysteries uncovered and the new generation of telescopes that will be built. http://www.facebook.com/home.php#/event.php?eid=56490093699

Key science projects

The SKA science impact will be extraordinary. Recently the SKA’s International Science Advisory Committee (ISAC) has agreed upon five principal science drivers against whose requirements any technical design must be tested.

> The cradle of life
There is increasing interest in the community in astrobiology and in the search for Earth-like planets. The SKA has the unique potential for finding evidence of extra-solar terrestrial planets and of other life like us.

>Strong field tests of gravity using pulsars and black holes
Pulsar surveys with the SKA can discover tens of thousands of pulsars, amongst which we expect to find a pulsar in orbit around a stellar-mass black hole and pulsars in close orbit around the super-massive black hole at the Galactic Centre. more…
> The origin and evolution of Cosmic Magnetism
Radio astronomy is uniquely placed in its capability to study magnetic fields at great distances. Large-scale polarimetric studies will allow us to completely characterize the evolution of magnetic fields in galaxies, clusters and the inter-galactic medium; to investigate the connection between the formation of magnetic fields and the formation of structure in the early Universe, and to provide solid constraints on when and how the first magnetic fields in the Universe were generated. more…

> Galaxy evolution, cosmology and dark energy
The original motivation for building the SKA was to detect HI in normal galaxies at high redshift. Such an experiment promises a particularly exciting result, in that the vast volume of space probed by an SKA HI galaxy survey will provide an exquisite matter power spectrum, with which we can compute the Universe’s Equation of State, and map out the strength of Dark Energy as a function of cosmic epoch. At the same time, the SKA’s unique capability to observe the neutral atomic component of gas in galaxies will allow us to chart the kinematics, merger history and environment of ordinary galaxies as they evolve from redshifts z~5 to the present. more…
> Probing the Dark Ages
The ensemble of the data collected by SKA can provide unique information on how the first galaxies and black holes assembled themselves, and how they influenced their environment. more…
