About BlueMUSE

BlueMUSE is an optical seeing-limited, blue-optimised, medium spectral resolution, panoramic integral-field-spectrograph, to be installed on one of the telescopes of the VLT on Cerro Paranal (Chile). The project is an evolution of the technology used on the very successful VLT / MUSE instrument, with a similar architecture and many similar systems, but with a new and distinct science case enabled by its main characteristics:

  • a wavelength coverage 350 – 580 nm
  • an average spectral resolution R=4000
  • a  field-of-view higher than 1arcmin²

BlueMUSE will offer new and unique science opportunities in many fields of astrophysics, beyond those possible with MUSE. Among the science goals available with this new instrument, it will survey large sample of massive stars in our galaxy and the Local Group, study ionized nebulae, starburst and low surface-brightness galaxies. At high redshift, it would allow us for the first time to detect the IGM unambiguously in emission, as well as study the evolution of the CGM properties near the peak of the Cosmic Star formation history.

  • Phase A Kick-Off with ESO

    We are pleased to announce that we had the BlueMUSE Phase A Kick Off at CRAL with ESO members. This first phase, that will last around 10 months will allow to validate our scientific goals, to develop a first design concept and to build a development plan for the future. This Kick Off is a… Read More »Phase A Kick-Off with ESO

  • Gate A1

    BlueMUSE just passed its Gate A1 with attendance from the consortium members and the ESO follow up team. This important milestone allowed us to review the overall project progress and prepare a plan for the ESO Phase A, starting in early 2024. We want to thank again everyone for their attendance and are looking forward… Read More »Gate A1

  • Gate A0

    The BlueMUSE Gate A0 milestone has been successfully passed at CRAL with attendees from all institutes both on-site and online. During two days, we reviewed the project main technological and scientific challenges and prepared a path for the coming months. It was the first official full consortium gathering and we are now looking forward to… Read More »Gate A0
