Description
We show that cyclic activity and Maunder-type grand minima can be explained by a dynamo driven by the instability of magnetic flux tubes in the overshoot layer at the bottom of the solar convection zone. The combination of a threshold in field strength for dynamo action and random fluctuations due to magnetic fields from the turbulent convection zone leads to activity cycles with strong amplitude variations and the occasional appearance of grand minima.

    The Gravitational-wave Optical Transient Observer (GOTO)
    The Gravitational-wave Optical Transient Observer (GOTO) is a project dedicated to identifying optical counterparts to gravitational-wave detections using a network of dedicated, wide-field telescopes. After almost a decade of design, construction, and commissioning work, the GOTO network is now fully operational with two antipodal sites: La Palma

    Innovative solution for upgrading commercial bearings for use in cryogenic instruments
    Infrared instruments for astronomy require many bearings for motion that must move in cryogenic conditions. There are poor and expensive options for this, and the companies with qualified bearings only supply after a long time. To attend these constrains, the Instituto de Astrofísica de Canarias (IAC) started to develop a procedure to upgrade
