SOXS (Son Of X-Shooter) is a single object spectrograph, covering from UV to infrared in one single shot.
SOXS was selected in 2015 by ESO (European Southern Observatory) after a call for new instruments at the 3.6m ESO New Technology Telescope at the La Silla Observatory, Chile. SOXS is built by an international consortium led by INAF (50%) and including Israel, UK, Finland, Chile and Denmark as partners.

INAF-Brera Astronomical Observatory is the project nerve centre. We are integrating the infrared arm in our cleaning room. We are developing the producing software for observing schedule on a night-by-night basis and we are contributing for data reduction pipeline.
During operative phase the observatory will be the centre for SOXS operations.

The New Technology Telescope or NTT is a 3.58-metre Ritchey-Chrétien telescope operated by the European Southern Observatory. It began operations in 1989. It is located in Chile at the La Silla Observatory.

As a reward for our efforts, ESO will compensate the SOXS Consortium with 180 observing nights per year for 5 years (900 nights). The science goals of the SOXS Consortium are focussed: the spectrograph will observe all kind of transient and variable sources discovered by different surveys with a highly flexible schedule, updated daily, based on the Target of Opportunity concept. It will provide a key spectroscopic partner to any kind of imaging survey, becoming one of the premier transient follow-up instruments in the Southern hemisphere. SOXS will study a mixture of transients encompassing all distance scales and branches of astronomy, including fast alerts (such as gamma-ray bursts and gravitational waves), mid-term alerts (such as supernovae and X-ray transients), and fixed-time events (such as the close-by passage of a minor planet or exoplanets). It will also have the scope to observe active galactic nuclei and blazars, tidal disruption events, fast radio bursts, and more.

SOXS will be installed at one of the Nasmyth foci of the NTT, replacing SOFI, a venerable and highly productive ESO instrument. Designed as a unique spectroscopic facility, SOXS will study transient sources following triggers and alerts from telescopes, satellites, and detectors worldwide. (Crediti ESO).

Besides of the consortium programs on guaranteed time, the instrument is offered to the ESO community for any kind of astrophysical target. The SOXS Consortium is in charge of the NTT operations, producing the observing schedule on a night-by-night basis. The schedule will be dynamical, merging SOXS and ESO target depending on our needs. The schedule is flexible and will give us the opportunity to react in real time to the new surprises the sky will offer us.
Now, (November 2021) SOXS is in its integration phase and a preliminary acceptance of the instrument from ESO is foreseen for the Summer 2022.
