Huub Rottgering |
| LOFAR, the Low Frequency Array, is a new low frequency telescope that is currently being built in the Netherlands. It will initially observe at frequencies from 30 to 240 MHz with baselines of up to 100 km. The aim for the second phase is to carry out sensitive observations below 30 MHz and to extend the maximum baselines up to 400 km. The design of LOFAR is driven by four fundamental astrophysical applications: (i) The Epoch of Reionisation; (ii) Extragalactic Surveys and their exploitation to study the formation and evolution of clusters, galaxies and black holes; (iii) Transient Sources and their association with high energy objects such as gamma ray bursts; (iv) Cosmic Ray Showers and their exploitation to study the origin of ultra-high energy cosmic rays. During this talk a number of issues related to LOFAR will be discussed including the science cases, instrumental concepts and time line. |
