Hello there! I’m Jacinta Delhaize. Welcome to my website and blog. I’m an Australian astronomer currently working as a Square Kilometre Array post-doctoral fellow at the University of Cape Town, South Africa. I started here recently in July 2018 and prior to that was a postdoc at the University of Zagreb, Croatia for four years.
I completed my PhD in radio astronomy at the International Centre for Radio Astronomy Research, University of Western Australia, and part-time at the University of Oxford. Prior to that I completed a Bachelor of Science with a physics major at the University of Western Australia.
I consider myself an observational radio astronomer. My research focuses on the field of galaxy evolution – trying to understand why the physical properties of galaxies have changed over the history of the Universe. To do this, I use large radio telescopes such as the Parkes 64m dish, the Australia Telescope Compact Array and the Karl G. Jansky Very Large Array. With these instruments we perform large-scale radio continuum and spectral line surveys of the sky and combine them with information from across the electromagnetic spectrum.
I’m also very passionate about science communication, popularisation and outreach. I think it’s essential to make our science accessible to everyone: including the general public, students, media, policy makers and other scientists. This helps to promote an interest and appreciation for science, the scientific method and critical thinking – which all impact our every day lives. I believe that effective science communication can literally change the world!
If you’d like to know more about the many great reasons to communicate astronomy, and how this can have a very meaningful impact on the world, check out my blog post on the topic.
About the feature image
The feature image at the top of the page is from the Galactic All Sky Survey (GASS). It shows the 21cm emission of hydrogen gas along the plane of our Milky Way galaxy. The survey was conducted with the Parkes radio telescope by Naomi McClure-Griffiths and team.
The colour in the image represents the velocity of the gas. And so this image shows light from hydrogen gas that is travelling towards and away from us. Hence it nicely matches the theme of `Travelling light’!
The purplish light you can see in the background is part of the Leading Arm of the Magellanic Stream – a huge stream of hydrogen gas getting ripped off the Large and Small Magellanic Clouds as they interact with the Milky Way.
I worked with this GASS data during some of my undergraduate/Honours research into the gas-to-dust ratio of the Magellanic Stream.
