Dame Jocelyn Bell Burnell, the discoverer of ‘pulsars’, was recently inaugurated as Pro-Chancellor of the University of Dublin. As a research student in Cambridge in 1967, she detected unusual radio pulses coming from beyond the solar system and helped identify the pulses as emanating from rapidly spinning, super-dense, collapsed stars, subsequently named ‘pulsars’. Her landmark detections were made using a low frequency radio telescope similar to LOFAR.
Astronomers have produced one of the best images ever made at the lowest frequencies of giant bubbles produce by super-massive black holes. Click on the following image for the full article:
The ground planes for the LBA Test Array arrived at Birr Castle and were placed on the site roughly were the LBA’s will be located. The ground planes are 3 x 3 metres in dimensions with a spacing of 15 cm and serve as a reflector for low frequency radio waves.
The following site was chosen to host the four LOFAR LBA antenna elements which will be set up and texted starting from January 2013. The site is located in the Rosse Observatory in Birr, Co. Offaly (www.rosseobservatory.ie). The I-LOFAR test array will test the capabilities of the LBA antenna elements individually and also linked together. The site has a great view of the southern sky and it is large enough to contain four 3 metres x 3 metres LBA antennas.
The Science Squad on RTE TV takes an entertaining look at some of the exciting and important scientific research that is currently underway in Ireland. From social networking to rugby tackle analysis and from health care monitoring to air travel, our presenters Aoibhinn Ni Shuilleabhain, Kathriona Devereux and Jonathan McCrea travel the country to meet the Irish scientists who are working at the forefront of research and innovation.
On July 12, the Science Squad visited Birr Castle to hear all about one of ireland’s most exciting proposed projects, the I-LOFAR radio telescope.
Dermot Desmond, the Irish financier and philanthropist, has become the first person to become a Founding Member of I-LOFAR. He was quickly followed by generous donations from Denis O’Brien and Joe Hogan.
“This is a great start for the project” according to Dr. Peter Gallagher, who is leading the Irish LOFAR consortium. “We can now begin to make firm plans to install a LOFAR radio telescope in Birr Castle Demesne, and link Ireland into a €150 million European network of radio telescopes.” The project would be one of the largest international science project that Ireland has ever participated in.
“We are now seeking about another 10 Founding Members and a Lead Donor to make this exciting project happen” says Gallagher. “This is an great prospect for Ireland, which will have direct benefits for Irish research, education, and indeed rural development.”

A brochure describing the I-LOFAR project is now available for download form the project website. Click on the image below to download a copy.
Ireland requires EUR 1.5 million to build a LOFAR station in Ireland and join the International LOFAR network of radio telescope.
This is a great opportunity for Ireland to engage in a flag-ship European project that is revolutionizing our understanding of the low-frequency radio Universe.
Congratulations to I-LOFAR consortium member, Prof. George Miley, who has just been named a Knight of the Order of the Dutch Lion.
George was instrumental in conceiving of and setting up the International LOFAR Telescope network, and has been a continuous supported of I-LOFAR.
Well done George!

Members of the I-LOFAR consortium visited the international LOFAR station in Potsdam in March 2012.
We took lots of photos and notes during the site visit, which we have included in the following summary document.
During the visit, we discussed practical issues associated with leveling the ground, drainage, fibre costs, site installation time-scales, and annual running costs. We also learned about single station observing modes.
Thanks to Prof. Gottfried Mann, Dr. Christian Volcks and Dr. Frank Breitling of the Institute of Astrophysics, Potsdam for arranging the visit and showing us round.
Scientists from the International LOFAR Telescope (ILT) today announced the kick-off of the project’s first all-sky survey at low radio frequencies and its first open call for observing proposals from the international astronomical community. LOFAR, the Low Frequency Array, is an innovative radio telescope built in the Netherlands and across northern Europe. LOFAR will make the still largely unexplored low-frequency radio sky accessible to astronomers for the first time. It will search for the first stars and black holes in the universe, hunt for cosmic radio bursts, pulsars, and ultra-high energy cosmic particles, study the sun and planets, and explore cosmic magnetic fields.
Above is an image of the Cygnus A radio galaxy observed by LOFAR at 240 MHz. LOFAR is being used to study supermassive black holes and the affect they have on their local environment. A classic example of an active galaxy is Cygnus A, which lies in a nearby cluster of galaxies at a distance of about 700 million lightyears. At the center of this galaxy is a powerful active nucleus that emits jets of plasma at relativistic speeds. An early LOFAR image at 240 MHz shown here that these jets extend far beyond the stellar part of the galaxy, up to 200 thousand light years from
the center, before abruptly interacting with the intra-cluster medium at impact points called hotspots. (Image Credits: J. McKean and M. Wise, ASTRON).
