A Journey Through the Last 100 Years of Astronomy, Coming to Birr in August 2019!

The International Astronomical Union’s 100th Anniversary Exhibition (IAU100) is coming to Birr! I-LOFAR is delighted to be hosting this unique exhibition celebrating the last 100 years of astronomy around the world. It will be launched on Thursday 8th of August and will then be on display from Friday 9th to Friday 16th of August.

For our launch we are very please to say that we will be joined by Professor Tom Ray from the Dublin Institute of Advanced studies (DIAS), one of our I-LOFAR Consortium members. Prof Ray is one of Ireland’s leading astronomers and the Irish representative on the ESO (European Southern Observatory) council. Prof Ray will be speaking at John’s Hall at 18:00 on Thursday 8th August and all are welcome to attend. 

This exhibition is a journey through some of the most significant and surprising breakthroughs that shaped astronomy, technology and culture over the last century. It is underpinned by three universal questions which are just as relevant today as they were a hundred years ago; 

What is the size and structure of the Universe? 

How do stars form and shine? 

Is there life elsewhere in the universe?

The exhibition has been travelling around the world for the past year, premiering in Vienna at the IAU General Assembly in August 2018, and is now here in Ireland for the next few months. It started in Armagh, until the 31st of July, next stop is Birr, and then it will move on to Dublin, Cork and Galway. 

The IAU100 Exhibition will be displayed in John’s Hall and the I-LOFAR Education Centre here in Birr. Birr Vintage Week and Arts Festival will also be taking place from the 2nd to the 10th of August, so be sure to check it all out!

I-LOFAR is hosting the IAU100 exhibition with support from Science Foundation Ireland and Offaly County Council.

Astronomers Publish New Map of the Sky Detecting Thousands of Previously Unknown Galaxies

– Team includes researchers from University College Dublin

– Data from I-LOFAR telescope in Birr, Co. Offaly used as part of the survey project

An international team of more than 200 astronomers from 18 countries, including researchers from University College Dublin (UCD), has today published the first phase of a major new sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope.

The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve.

A special issue of the scientific journal Astronomy & Astrophysics is dedicated to the first twenty-six research papers describing the survey and its first results.

Radio astronomy reveals processes in the Universe that we cannot see with optical instruments. In this first part of the sky survey, LOFAR observed a quarter of the northern hemisphere at low radio frequencies. At this point, approximately ten percent of that data is now being made public. It maps three hundred thousand sources, almost all of which are galaxies in the distant Universe; their radio signals have travelled billions of light years before reaching Earth.

Associate Professor John Quinn, UCD School of Physics and his PhD student, Sean Mooney, who is supported through an Irish Research Council Government of Ireland Postgraduate Scholarship, are members of the LOFAR surveys key science project.

They are lead authors on one of the papers published today and contributed to several others. Their paper is focused on the jets from supermassive black holes that are pointed towards the Earth.

Professor Huub Röttgering, Leiden University, and principal investigator of the surveys team said, “If we take a radio telescope and we look up at the sky, we see mainly emission from the immediate environment of massive black holes. With LOFAR we hope to answer the fascinating question: where do those black holes come from?”

“What we do know is that black holes are pretty messy eaters. When gas falls onto them they emit jets of material that can be seen at radio wavelengths.”

Associate Professor John Quinn, UCD School of Physics said, “The LOFAR survey provides us with an unprecedented view of galaxies with supermassive black holes at their centers, and how they evolve. The sensitivity and resolution of this LOFAR survey is unparalleled at low frequencies, and the technological advancements required to make this possible are relatively recent.”

Sean Mooney, PhD student, UCD School of Physics said, “We’re interested in studying high-speed jets of plasma that are ejected from supermassive black holes, and the survey is a goldmine of information for us. Now that the data are public, it will surely prove to be a useful resource for many other astrophysicists around the world also.”

Creating low-frequency radio sky maps requires significant computational resources. Much of the analysis has been done at a data centre at SURFsara in Amsterdam, which hosts over 20,000 terabytes of LOFAR data.

“It is the largest astronomical data collection in the world. Processing the enormous data sets is a huge challenge for scientists. What normally would have taken centuries on a regular computer was processed in less than one year using the high throughput compute cluster (Grid) and expertise”, said Dr Raymond Oonk, SURFsara, a member of the international team of researchers.

Machine learning algorithms are being used to automate parts of the analysis, with some of this work being done at UCD on powerful computing clusters.

The international LOFAR telescope consists of a European network of radio antennas, connected by a high-speed fibre-optic network spanning seven countries. LOFAR was designed, built and is now operated by ASTRON (Netherlands Institute for Radio Astronomy), with its core located in Exloo in the Netherlands.

The Irish station was installed in the grounds of Birr Castle, Co. Offaly in 2017, with support from Science Foundation Ireland, Enterprise Ireland, the Department of Business, Enterprise, and Innovation, Offaly County Council, the Department of Culture, Heritage, and Gaeltacht, UCD, TCD, Armagh Observatory, DCU, UCC, NUIG, DIAS, and AIT.

The 26 research papers in the special issue of Astronomy & Astrophysics were done with only the first two percent of the sky survey. The team aims to make sensitive high-resolution images of the whole northern sky, which will reveal 15 million radio sources in total.

“This sky map will be a wonderful scientific legacy for the future. It is a testimony to the designers of LOFAR that this telescope performs so well”, said Carole Jackson, Director General of ASTRON.

“Just imagine some of the discoveries we may make along the way. I certainly look forward to it”, she added.

The special issue of Astronomy & Astrophysics is titled LOFAR Surveys.

The paper which Sean Mooney and Associate Professor John Quinn are lead authors is entitled Blazars in the LOFAR Two-Metre Sky Survey First Data Release.

LOFAR Radio Telescope Reveals Secrets of Solar Storms

Dublin, Ireland, February 18, 2019: An international team of scientists from Trinity College Dublin, the University of Helsinki, and the Dublin Institute for Advanced Studies today announced a major discovery on the nature of solar storms in the journal Nature Astronomy (PDF available at Springer Nature SharedIt).

The Sun is the closest star to our planet in the Universe, and like many stars, it is far from quiet. Sunspots, many times the size of Earth, can appear on its surface and store enormous reservoirs of energy. And it is within these regions that huge explosions called solar storms occur.

Solar storms are spectacular eruptions of billions of tonnes of hot gas travelling at millions of kilometres an hour. If they impact the Earth, they can produce beautiful displays of the aurora, but they can also cause problems with communication and navigation systems and power grids.  

In 1859, the largest solar storm ever observed – the so-called Carrington Event – erupted. Within hours, it generated displays of the aurora as far south as Italy and Cuba and caused interruptions in early telegraph systems in Europe and the US. In Ireland, it reportedly stopped London stock market prices being received in Dublin “due to a strange atmospheric phenomenon”.

Our society is now even more dependent on technology, and solar storms have the potential to cause significant effect on their performance. In 2003, transformers in South Africa were damaged, while Swedish air traffic control systems were closed down in 2015 for more than an hour due to effects associated with a solar storm. More recently, emergency response communications were interrupted during hurricane season in September 2017 in the Caribbean.

“We used data from the Low Frequency Array, LOFAR, together with images from NASA, NOAA and ESA spacecraft to work out where particles are accelerated by the particularly large solar storm on September 10, 2017, soon after we turned on the Irish LOFAR station”, said Dr Diana Morosan, the lead author on the publication, and affiliated with Trinity and the University of Helsinki.

“We built the Irish LOFAR station at Birr Castle to study how solar storms move and how they generate bursts of radio waves”, according to Professor Peter Gallagher of the Dublin Institute for Advanced Studies, who leads the I-LOFAR project on behalf of Trinity. “We used I-LOFAR to detect tiny radio bursts in coordination with the LOFAR core in the Netherlands to work out where the burst were coming from.”

“Our observations enabled us to work out that the solar storm created a huge shock wave as it erupted from the Sun, which then accelerated electrons that generated radio bursts. This gives us an amazingly detailed insight into how solar storms work, and may in the future help us to produce more accurate forecasts of when solar radio bursts occur and how they impact the Earth”, said Dr Morosan.

Speaking about the research, Professor Mark Ferguson, Director General of Science Foundation Ireland and Chief Scientific Adviser to the Government of Ireland, said: “Less than two years ago we officially launched the I-LOFAR radio telescope at Birr Castle, and it is fantastic to see the fascinating breakthroughs it has already made possible. It demonstrates the tangible rewards that arise from investing in cutting-edge infrastructure which facilitates collaborations between researchers and leads to exciting discoveries. I wish to congratulate the individuals from Trinity College Dublin, DIAS and University of Helsinki for their impressive work on solar storms, and I am confident that their future work with I-LOFAR will continue to provide us with invaluable insights.”

“These excellent results from I-LOFAR demonstrate the quality of the site in Ireland and the benefits of international collaboration in research and innovation. I am delighted to see such a return from the Government funding for I-LOFAR.” Minister of State for Training, Skills, Innovation, Research and Development, John Halligan T.D.
