10 years of LOFAR highlights: The use of GPS receivers and rubidium modules to sync the stations
One of the important aspects of radio telescopes, in general, is the synchronisation in between antennas and for LOFAR in particular the synchronization between stations
Happy birthday to LOFAR!
Today LOFAR celebrates its tenth anniversary.
10 years of LOFAR highlights: A LOFAR View of the Turbulent Ionosphere
The view of the radio universe at the VHF frequencies of LOFAR is strongly affected by the Earth’s ionosphere.
10 years of LOFAR highlights: Infographic – Off the shelf GPU’s
This infographic explains how LOFAR utilizes off the shelf GPU’s to create a detailed image from data streams of radio waves.
10 years of LOFAR highlights: A large light-mass component of cosmic rays at 1017-1017.5 eV from radio observations
LOFAR is a highly flexible instrument, which can be utilized for many things. Each antenna, for example, has a 5-second buffer, which can be used to measure very short, strong signals.
10 years of LOFAR highlights: A complete image of the visible sky every second
The behaviour of black holes and neutron stars can expose some of the most extreme tests of physical law. Therefore, this behaviour can be used to find answers to questions as to how black holes are born and to the origin of magnetic fields and cosmic rays.
10 years of LOFAR highlights: The LOFAR Two-metre Sky Survey
A detailed radio image of the entire northern sky in the frequency range of 120-168 MHz. That is what the LOFAR Two-metre Sky Survey (LoTTS) aims to achieve.
10 years of LOFAR highlights: Improved upper limits on the 21 cm signal power spectrum of neutral hydrogen at z ≈ 9.1 from LOFAR
13.8 billion years ago, our Universe was created in an event called the Big Bang. “Only” 0.5 billion years later, the Universe entered a pivotal stage.
Announcement: WSRT-Apertif Surveys to continue throughout 2021
The large-scale Apertif surveys with the Westerbork Synthesis Radio Telescope (WSRT) that started on 1 July 2019 will continue to be supported during 2021.
10 years of LOFAR highlights: Using the existing SurfNet infrastructure to connect international stations and its European counterparts
In addition to the 40 Dutch antenna stations, LOFAR has 14 antenna stations elsewhere in Europe. Just like the antenna stations in the Netherlands, the European stations also send their observation data via fibre optic connections to the central processor (CEP) of LOFAR at Groningen.
10 years of LOFAR highlights: Gentle reenergization of electrons in merging galaxy clusters
Supermassive black holes can leave a trail of energetic particles that astronomers are able to detect using radio telescopes. Usually the radio emissions from these particles fade away and become invisible.
10 years of LOFAR highlights: Infographic – The evolution of LOFAR supercomputers
This infographic shows the ‘evolution’ of supercomputers used for LOFAR.
