MUSE Science Verification

General Information

An integral part of the commissioning of a new instrument at the VLT is the Science Verification phase. SV programmes include a set of typical scientific observations that should verify and demonstrate to the community the capabilities of the new instrument in the operational framework of the VLT Observatory. In accordance with its SV Policy and Procedures (http://www.eso.org/sci/activities/vltsv/svdoc.pdf) ESO encourages the community to submit also highly challenging or risky science observations that will push MUSE/AOF and the VLT to its limits in order to better understand the performance parameter space and its envelope. Such observations should focus on the instruments core modes in order to benefit a wide community.

MUSE, the Multi-Unit Spectroscopic Explorer, is an Integral Field Spectrograph located at the Nasmyth B focus of Yepun, the VLT UT4 telescope. It has a modular structure composed of 24 identical IFU modules that together sample, in Wide Field Mode (WFM), a near-contiguous 1 squared arcmin field of view. Spectrally the instrument samples almost the full optical domain with a mean resolution of 3000. With the GALACSI Adaptive Optics system in combination with the VLT Adaptive Optics Facility, MUSE will offer an AO-corrected 1'x1' field of view with 0."2 sampling.

The new adaptive-optics assisted MUSE mode is offered to the community for Science Verification (SV) for 3 nights in August 2017. All astronomers are invited to participate in this opportunity to obtain unique science with these the MUSE AO-supported wide-field mode and thus to demonstrate its scientific capabilities. A call for proposals has been issued and the community was invited to submit proposals for the MUSE WFM-AO science verification using the simplified proposal template. The deadline for this call for proposals is 14 June 2017, 18:00 CEST.

Proposals will be reviewed by an internal panel and allocated time on the basis of scientific merit and feasibility, as well as in the demonstrated ability of the Principle Investigators to deliver results on a timely basis.

The observations will be conducted during the nights of 12-14 August 2017 in Service Mode by a dedicated team of ESO astronomers. The MUSE WFM SV team will be able to assist the successful PI’s in the preparation and optimisation of the OB’s on a best effort basis only.

The latest version of the MUSE data reduction pipeline will be available for reduction of the SV data. Proposers are reminded that all SV data are made public worldwide immediately after passing the usual quality control checks.

Short description of the AO-WFM of MUSE

GALACSI (https://www.eso.org/sci/facilities/develop/ao/sys/galacsi.html) is an AO system developed to increase the performance of MUSE. It uses a 4 laser guide star system (LGS) and the deformable secondary mirror on UT4 to provide a wave-front that is corrected for the turbulent atmospheric ground layer. It shall double the ensquared energy in one spatial pixel at 750nm by correcting the ground-layer turbulence across the entire field of view. One visible natural Tip-Tilt Star (TTS) will be used to correct for the remaining atmospheric tip-tilt. This TTS has to be located between 52" and 105" off axis and must be brighter than R=17.5 mag and needs to be provided in the proposal.

The MUSE ETC has not been updated for the new mode yet, as the commissioning is still pending. We encourage the proposers to use the current MUSE ETC and use a slightly increased image quality for the calculation of the exposure times.

Original MUSE Science Verification from 2014 (obsolete)

Seventeen nights have been allocated to the MUSE SV during the periods: June 20 - 29 and August 18-24 2014.

Approved Programs

A total of 50 proposals have been allocated SV time. The observations will be performed in "service mode style" by a dedicated team and the collected data are made available to the whole user community. See VLT Science Verification Policy and Procedures for more details.

WARNING: all (raw) data and calibrations are becoming public shortly after observations.
There is no proprietary period nor earlier data release to the PIs.

If you have any questions on the MUSE Science Verification, please contact Jorge Melnick

Below is the list of programs with the project titles as well as the links to the corresponding raw archive data.The calibration frames can be obtained via the CalSelector in the ESO archive query. Please see CalSelector service for more details.
