LOFAR

LOFAR, the LOw Frequency ARray, is an innovative new radio telescope currently under construction in the Netherlands, which will continuously monitor the radio sky in the frequency range 10-240 MHz.

Transients Key Project

Transient sources are one of the four Key Projects of LOFAR. Under its remit come all time-variable astronomical radio sources, including pulsars, gamma-ray bursts, X-ray binaries, radio supernovae, flare stars, and even exo-planets. With its continuous monitoring of a large area of sky, it is hoped that LOFAR will detect many new transient events, and provide alerts to the international community for follow-up observations at other wavelengths.

News

The WSRT LFFE observations have been approved. We were awarded 12h to observe SS 433, GRS 1915+105, and Cygnus X-3 at both 92cm and with the LFFEs. We were also awarded four 12h runs over the course of a month with the LFFEs to observe any new northern hemisphere transient that goes off.

We are continuing to monitor 3C 454.3 at regular intervals, since it flared in May 2005 (ATels 484, 488). Thus far, there has been no evidence for a brightening at 330 MHz.

Jobs

The Astronomical Institute of the University of Amsterdam has one 2.5-year postdoctoral position available in the area of radio transient searches with LOFAR, starting in the autumn of 2005. Depending on funding, there may also be a PhD student position and an additional programmer/software manager position available effective January 2006. Click here for more details.
