Glitch – Investigating the densest matter in the universe: The 2016 glitch of the Vela pulsar

Thursday 7 June 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

Pulsars are neutron stars that are the remnants of supernova explosions. They are highly dense and rotate rapidly, some with accuracy better than atomic clocks. The Vela pulsar famously “glitches” or speeds up in rotation roughly every three years. No glitch has ever been observed in-action with a radio telescope large enough to see individual pulses, until now. Some remarkable events occurred and these will be covered in detail. The presentation will be aimed at people who have a general interest in astronomy.

Abstract

Photonics is a disruptive technology whose impact and potential to transform industry and our lives has been likened to those of electronics. We all use photonics enabled devices every day such as lasers, sensors and optical fibres, even without realising it. The global photonics market is currently worth around USD$500 billion and is expected to grow to over US$600 billion by 2023, which makes physics and photonics a very attractive prospect to join this locally and internationally growing high-tech industry.

This talk will explore the different approaches and devices used for harnessing light to measure the world around us, for example temperature, magnetic fields, gravity, corrosion and much more.

Biography

Shedding light on dark matter

Thursday 10 May 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Chris Power
International Centre for Radio Astronomy Research, University of Western Australia

A standard cosmological model has emerged over the last 30 or so years in which the matter content of the Universe is predominantly in the form of an exotic non-baryonic matter, quite unlike the ordinary matter of everyday experience. Uncovering the physical nature of this dark matter is one of the most pressing problems facing fundamental physics and cosmology in the 21st century.

Astronomical observations and modelling have played a key role in establishing what we think we know so far about the dark matter – the widely favoured Cold Dark Matter (CDM) model predicts successfully the large-scale distribution of galaxies in a cosmic web, and is consistent with our deepest observations of the early Universe, which show that galaxies, groups, and cluster are the product of mergers over the last 13 or so billion years of cosmic time. The CDM model is not without its problems, however, and, in particular, it is on the smallest galactic mass scales of dwarfs and satellites of the kind we find around the Milky Way that it has faced its most severe challenges.

I will review what the latest observations and numerical simulations are telling us about dark matter, and I will speculate on what we might learn in the coming years, especially as observation, theory, and experiment place more stringent limits on what the dark matter can be.

From Mad Scientists to Eco-Warriors: The changing image of scientists in fiction and film

Tuesday 10 April 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Adjunct Associate Professor Roslynn Haynes
School of English, Media and Performing Arts, University of New South Wales

For approximately 600 years, from 1380 to 1980, scientists or their predecessors, the alchemists and natural philosophers, fared ill at the hands of writers and, later, film makers.

They were obsessed to the point of madness, or evil, amoral, arrogant, impersonal, and inhuman. At best, they were well intentioned but blind to the dangers of forces they barely controlled. They were Faustus and Frankenstein, Jekyll and Moreau, Caligari and Strangelove – the scientists of film and fiction, cultural archetypes that reflected ancient fears of tampering with the unknown or unleashing the little-understood powers of nature.

Yet, since the 1990s, there has been a trend by novelists to present scientists as more complex, realistic figures, many honest and admirable even if confused as to their role. They are eco-warriors saving the planet, or medical researchers discovering new cures for humanity. However, in films, the mad, evil stereotype endures. What are the reasons for this disparity?  What do they teach us about the difficulties scientists have in convincing politicians and large sections of society of the need to take environmental pollution and climate change seriously?

DavidOttawayGravitational Wave Detection and the Birth of Multi Messenger Astronomy”

Prof. David Ottaway,
University of Adelaide

 

Abstract:

The existence of gravitational waves was first predicted by Albert Einstein as a direct consequence of his Theory of General Relativity. These waves were first directly detected on Earth a little more than 2 years ago. These waves were created by the collision between two black holes that occurred over a billion years ago. The significance of this detection was celebrated with the awarding of the 2017 Nobel Prize in Physics to Weiss, Barish and Thorne. Further detections have helped solve the mystery of how gold and other heavy elements are created in the Universe. In this talk I will present an overview of the field of gravitational wave detection and how this has led to the opening of a new window on the universe.

The Birth of Suns

Thursday 30 November 2017, 6.00-7.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Mark Krumholz
Research School of Astronomy and Astrophysics, Australian National University

We’ve all learned that space is an empty vacuum, but it’s not. The space between the stars in our Galaxy contains, on average, about 1 atom per cubic centimeter. That’s a better vacuum than the best vacuum chamber we know how to make, but there are a lot of cubic centimeters in interstellar space, so the mass of all the gas between the stars adds up to about 10% of the mass of all the stars put together. The temperature of this gas varies enormously from place to place in the Galaxy, with temperatures as high as
millions of degrees and as low as a few degrees above absolute zero.

In the coldest regions of interstellar space, over millions of years gravity is able to draw the atoms together into immense clouds that ultimately condense into clusters of new stars. In our Galaxy, this process produces stars at a rate of about 1 new Sun per year, and the stars it makes are typically the size of the Sun or a little smaller. While we understand how this happens in general outline, many fundamental questions remain unanswered. What sets the rate at which stars form? What determines the final sizes of the individual stars? Where did our Sun form, and what happened to its siblings, the stars that formed out of the same cloud?

In this talk Mark will describe what we currently know, and what we don’t, about the birth of new Suns.
