Panoptic spectroscopy of our universe
with OSIRIS+MAAT at GTC

MAAT* (Mirror-slicer Array for Astronomical Transients) is proposed as a visitor mirror-slicer optical system that will allow the OSIRIS spectrograph on the GTC the capability to perform Integral-Field Spectroscopy (IFS) over a seeing-limited field-of-view 14.20'' x 10'' with a slice width of 0.303''. MAAT will enhance the resolution power of OSIRIS by 1.6 times with respect to its 0.6'' wide long-slit. All the eleven OSIRIS Grisms and VPHs will be available to provide broad spectral coverage with low / moderate resolution (R=600 up to 4100) in the 360 - 1000 nm spectral range.

MAAT top-level requirements will broaden its use to the needs of the GTC community for a wide range of outstanding science topics that covers the entire astronomy given its unique observing capabilities well beyond time-domain astronomy. The GTC equipped with OSIRIS+MAAT will also play a fundamental role in synergy with other facilities operating at the Observatorio del Roque de los Muchachos.

This 1-day workshop intends to collect the interest from the GTC community on MAAT. We will present the different aspects of the instrument, including science and technical specifications, and an outline of the instrument concept. Everyone is welcome to present key science projects that will encourage and support the development of this new facility.

Date: 5 May 2020
Venue: virtual format (link will be provided for remote connection)
Registration deadline April 30th.


Note: Given de development of events, we are working to run this meeting in a virtual format keeping the original date. So, please, go ahead and register to contribute with your valuable ideas so that MAAT@GTC becomes a wonderful instrument for the community.

*MAAT refers to the ancient Egyptian concepts of truth, balance, order, harmony, law, morality, justice, and cosmic order.
