First Pulsar Light with I-LOFAR!

Pulsars are rotating neutron stars that beam radiation into space like rapidly rotating lighthouses. Last week a team of scientists from Ireland and the UK used I-LOFAR and a new Dell-EMC cluster called the “REALtime Transient Acquisition Cluster (REALTA)” to observe our first pulsar, B0950+08. The plot below shows the first thirty seconds of an observation of […]

Big Data Processing for I-LOFAR: REALTA

I-LOFAR is a true ‘big data’ project, and as part of the International LOFAR Telescope, is a pathfinder telescope to the future Square Kilometre Array telescope, which will create perhaps the largest dataset in the world (an exabyte per day!). To date, the data processing capabilities of  I-LOFAR have not  been sufficient to allow the telescope study astronomy objects […]

Ready for Space Explorers!

On June 5, 2018 we completed the refurbishment of our new I-LOFAR Education Centre & Control Room at the Rosse Observatory, Birr Castle, Co. Offaly. The Education Centre will be used to host groups of school children, university students, researchers, and tour groups interested in learning about the fascinating science and engineering of I-LOFAR. The […]

Station Control using the LCU

Software Level Control processes in a LOFAR station are collected in groups called software levels. The user does not need to manually start and stop a number of processes, but each level contains processes for certain actions in the station, and appropriate processes are started / stopped when entering a given level. Users can query […]

Station Signal Processing Pipeline

1. Antennas LOFAR station is a wide-band radio receiver, which operates at the frequency range from 10 MHz to 240 MHz. The full reception band is divided into low band (10 MHz – 90 MHz) and high band (110 MHz – 240 MHz). The frequencies in between low band and high band are not used […]

Station Handover

Once you have completed your shift as I-LOFAR Chief Observer, please follow the following steps. Send an email to observer@astron.nl to inform ASTRON the station is ready to be handed over to international mode. CC observer@lofar.ie Send an email to observer@lofar.ie summarising the observations, mention the mode used and if other tests were run (e.g. […]

I-LOFAR User’s Guide

Welcome to the I-LOFAR User’s Guide. Below you will find details on how to log in to the I-LOFAR Control Computer (ICC) and the Local Control Computer (LCU) and how to run a variety of observation scripts. The ICC is located in the I-LOFAR Control Room, while the LCU is located in the International LOFAR […]

Introduction to Science, Operations and Data Analysis with an International LOFAR Station

School of Physics, University College Dublin, Belfield, Dublin 4, Ireland.  January 8-10, 2018 Summary This workshop will introduce researchers to LOFAR single-station science, operations and data analysis. The workshop will cover many aspects of an International LOFAR Station, from the capabilities of the station hardware to the software pipelines and science products that it produces. […]

Honorary Doctorates for World-Leaders in Astronomy

This week, UCD and TCD awarded Honorary Doctorates to two leading individuals in the world of astronomy. Congratulations to both Prof. George Miley, one of the originators of the LOFAR radio telescope concept, and Ms. Naledi Pandor, a key player in the development of the Square Kilometre Array and astronomy in general in South Africa.
