The EMIR spectrograph is now installed on the Gran Telescopio CANARIAS (GTC)PHOTONEWS

Advertised on

On Thursday June 2nd the EMIR spectrograph was successfully linked to the Gran Telescopio CANARIAS (GTC). After several days of trials following its arrival at the Roque de los Muchachos Observatory, on Wednesday it was moved to the base of the telescope and on Thursday morning it was maneuvered by crane up to the level of the side platforms of the GTC, and attached to the rotator where it will be in place to receive the light from the telescope.

The teamwork between the groups from EMIR and the GTC was critical for the correct performance of these manoeuvres, which were very complicated because of the weight of the instrument (5 tonnes) and its size (almost 3 metres in diameter), as well as the height through which it need hoisting (12 metres). In the coming days the teams will carry on with tests at room temperature, and will then cool the instrument down to its working temperature, and will make final adjustments with the instrument cooled, leaving it ready for “first light” which will probably take place on June 13th.

EMIR is an instrument designed, built, assembled and verified entirely in the IAC. It will obtain images and spectra in the near infrared, which will allow it to observe the coldest and most distant objects in the universe. To work in this wavelength range it needs cooling down to -200ºC, which is achieved by enclosing it completely in a cryogenic tank.

Media who are interested can take images of the work being carried out with EMIR next Monday, June 6th, between 10.00 a.m. and 12.30 p.m. To do this it will be necessary to receive accreditation, sending an email to prensa [at] iac.es (prensa[at]iac[dot]es).

    New DESI Results Weigh In On Gravity
    Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark Energy Spectroscopic Instrument (DESI) has traced how this cosmic structure grew over the past 11 billion years, providing the most precise test to date of gravity at very large scales. DESI is an international collaboration of more than 900 researchers, included the Instituto de Astrofísica de Canarias (IAC), from over 70 institutions around the world and is managed by

    Claude Nicollier tells of his experience as an astronaut at the IAC
    On Wednesday 30 October, the headquarters of the Instituto de Astrofísica de Canarias (IAC) received a talk by the first Swiss astronaut, Claude Nicollier, who wanted to share his experience in space with the personnel of the IAC. Claude Nicollier is the first Swiss astronaut to have flown into space. After his studies at the Universities of Geneva and Lausanne, Claude joined ESA as a member of their first group of astronauts. Since 2007 Nicollier has been a Professor at the Federal Polytechnical School at Lausanne. He has spent more than 1000 hours in space (more than 42 days) including a
