First Light for HORS on the Gran Telescopio CANARIAS

26/05/2015
The HORS spectrograph, one of the supported technology projects of the SO Program at the IAC, was successfully installed on the Gran Telescopio CANARIAS (GTC) last week, and observed its “first light” through the telescope last Saturday. After a battery of tests of the optics, electronics, and software, on Saturday night the GTC pointed at the Pole Star, and its light was analyzed by HORS. A few more months of trials are coming and then it is hope that HORS will begin routine use as a Visiting Instrument on the GTC early in 2016. The new instrument will enable the GTC to analyze light with a resolution ten times higher than any of the other instruments on the telescope. >> Further information

The second QUIJOTE telescope ready to join its partner

19/01/2015
The final on-site acceptance tests of the second QUIJOTE telescope were successfully conducted during the last weeks, in which the performance of the telescope was checked, including the different operation modes. Its installation at the Teide Observatory, in Tenerife, was completed in early November, 2014 . The telescope's rotary joint, where all electrical, communication and fluid channels converge to allow the telescope fully and continuously rotate on its axis, were integrated in that phase. QUIJOTE-II is now ready to receive the TGI instrument and join its partner in the study of the cosmic microwave background radiation.

One step closer to confirm (or not) the inflationary epoch

28/08/2014
The IAC has completed the integration and testing of the first pixel for the second QUIJOTE instrument, the TGI (Thirty GHz Instrument), which will confirm or deny the detection of B-modes in the polarization of the cosmic microwave background. The first telescope and the first instrument are both operating in the band from 10 to 20 GHz since November 2012, at the Teide Observatory. The second telescope has recently been installed at the Observatory, and the TGI is in the integration stage at the IAC headquarters. Both the second telescope and TGI are planned to be in commissioning by the end of 2014, covering the range from 26 to 36 GHz. >>Read more

The instrument is expected to be used in more than twenty different fields of astrophysics, from exoplanet transits to black holes.

WEAVE Preliminary Design Reviews (PDRs) held at the IAC

13/06/2014
WEAVE is an international project with IAC participation, including a Severo Ochoa postdoc working on the development of specific science analysis tools, part of the instrument Science Data System (SDS). Two PDRs of specific WEAVE subsystems have been held at IAC. On June 10th, it was organized the "PDR of the SDS for the WEAVE surveys", where all the SDS systems were reviewed by external experts, before starting the final design phase. This review was conducted for each subsystem, to evaluate the progress and technical adequacy of the selected design approaches, with a focus on the compatibility between science requirements and preliminary design. On June 12th, the "PDR for the WEAVE prime focus corrector translation subsystem" was also held at the IAC.

The polished fold mirrors of APOGEE -2 South arrive at the UVa

14/03/2014
The polished folding mirrors of APOGEE-2 South arrived at the University of Virginia (UVa) in early March 2014. The IAC is involved in the construction of the new spectrograph for APOGEE-2 South, essentially a copy of the original APOGEE spectrograph, with the Severo Ochoa program support focused on polishing of the folding mirrors #1 and #2 of the spectrograph, as well as with engineering support from the Technology division to assess the effectiveness of seismic protection measures under consideration. The polishing was carried out by the Nu-Tek Precision Optical Corporation at the U.S., who did the same job for the original instrument. The mirrors have now been delivered to the UVa where the second APOGEE instrument is being built. (Picture: original APOGEE spectrograph. Image credit: S. R. Majewski)

5th technical meeting on CARMENES AIV to be held in Barcelona.

22/01/2014
The 5th technical meeting on CARMENES AIV progress will be held in Barcelona from the 10th to the 13th of February 2014. Víctor Sánchez Béjar (project scientist) and Pablo Redondo (mechanical engineer) will attend the meeting as IAC´s representatives. The mission regarding the mechanics is to close the detailed design of the optomechanical mounts assigned as IAC´s contribution to the project (Off-Axis Parabolic Mirror, Fiber Input Unit and Cross Disperser, for both channels, visible and infrared). The detailed design has been produced by IAC in collaboration with the optical and mechanical teams of CARMENES external to IAC, since the kick off of our assignment in September 2013.

HARMONI Design Workshop

20/01/2014
IAC hosted the "HARMONI Design Workshop" from January 14 to January 16, 2014. The meeting was attended by 28 engineers and scientists of the partner institutions, Oxford University, UKATC, CRAL, ONERA, CAB-CSIC and IAC. HARMONI is the first light integral field spectrograph for the 39m European Extremely Large Telescope -E-ELT- from ESO. The project is now in an "Interim Study" period (partially supported by Severo Ochoa), mainly focused in the revision of the Phase-A instrument design and project definition to improve and adapt to the new E-ELT concept. The aims of the workshop were to review the current status of the engineering, science and management activities of the International Consortium.

ESPRESSO: The next European exoplanet hunter

15/01/2014
The Astronomische Nachrichten has published an article about the expected performance of ESPRESSO. The spectrograph will be installed at the Combined- Coudé Laboratory of the VLT and linked to the four 8.2 m Unit Telescopes (UT) through four optical Coudé trains. ESPRESSO will combine efficiency and extreme spectroscopic precision. The project passed the final design review in May 2013 and entered the manufacturing phase. ESPRESSO will be installed at the Paranal Observatory in 2016 and its operation is planned to start by the end of the same year. Download the paper for more information.

IDOM company will manufacture Wide FastCam Instrument

19/12/2013
After an open competition, the IDOM company is in charge of the design and manufacture of the optomechanics of the instrument. The concept that they propose is a tubular bench of welded aluminum, in which its structure also performs as a protective enclosure. The two mirrors would be fitted in two flanges on adjustable cells with three screws and the two camera lenses, the detector and the filter wheel would be fitted with a third flange. Once this design is approved, the manufacturing of the instrument will be easy. Consequently the first prototype should be ready in spring 2014.
