I-LOFAR science & techniques workshop 2020

I-LOFAR Education Centre, Birr Castle, Co. Offaly 

2-4 March 2020

Summary

This workshop aims to bring together the Irish LOFAR community to present recent scientific results and engage in a workshop on the use of LOFAR data. We encourage contributed talks from any recent or ongoing research with LOFAR, ranging from work in progress to published, covering all topics from astronomy research to data science and computing.

For the data workshop, all LOFAR user-levels are welcome. We’ll be providing introductory talks on LOFAR technology as well as an introduction to scheduling LOFAR observations and processing data. There will be a particular focus on the use of data from LOFAR as a single station, but we’ll also be providing some overviews of using LOFAR ILT data, including data from beam-formed observations and interferometric imaging.

Registration

To register please email eoin.carley@dias.ie by January 15th 2020 with the following info:

  • Name:
  • Affiliation:
  • Talk title (if you wish to give one):
  • Dietary restrictions:

The talk formats will be 15 mins + 5 mins of questions (that may change depending on how many contributions we have)

Registration for the workshop is €50 and can be paid in cash.

Software

All tutorials will be given using the Python programming language (Python v3.6 and v2.7). We recommend that you run Python using Jupiter and/or Spyder, which can be installed using Anaconda. Further details on how to install these packages can be found here. An excellent introduction to Python for the analysis of astronomical data can be found at Python4Astronomers.

Internet Access

Wifi access will be provided via eduroam. Please ensure that you have registered for eduroam by contacting your IT services at your home institution before arriving in Birr.

I-LOFAR Radio Telescope Reveals Secrets of Solar Shockwaves

The Sun may appear to be a constant force in our solar system, but it’s not as sleepy as you may think. In fact, our Sun can produce giant explosions that release vasts amount of electromagnetic radiation and electrically charged particles into space. These explosions, often referred to as solar storms, can be so fierce that they produce shock waves that propagate towards the Earth. Ultimately these shockwaves can cause a variety of potentially dangerous ‘space weather’ effects including interruptions to telecommunications and power, damage to satellites, and astronauts and passengers on commercial aircraft exposed to potentially lethal  doses of radiation. 

A new paper published in the scientific journal Astronomy & Astrophysics by members of the I-LOFAR consortium has provided new insights into how solar storms drive shockwaves.

“On  September 2, 2017, soon after the Irish LOFAR station was turned on, the Sun produced a solar storm that drove a shock wave. We used data from the  NASA and NOAA spacecraft to track the shock wave as it moved through the Sun’s atmosphere, while I-LOFAR was able to detect radio bursts generated by the shock.” said Trinity College Dublin postgraduate student Ciara Maguire, the lead author on the publication.

Caption The Sun’s magnetic fields together is an ultraviolet image of the Sun from NOAA’s GOES spacecraft. The blue arcs tell us where the shock was when a radio burst was observed by I-LOFAR.

These observations enabled scientists to work out how the shock wave accelerated electrons and generated radio bursts. This gives us a detailed insight into how shock waves form and evolve over time. These shocks are a phenomenon found throughout the Universe, including in supernovae, black holes, and distant stars so understanding shocks triggered by the Sun could help to unveil more details about the physics at play.
