Descripción
Two broad components in the strongest UV emission lines of NGC 5548 are identified. The components respond differently to continuum changes. A normal broad (5000 km/sec) line is related to the UV flux, but the data-set only provides an upper limit for the possible lag. The very broad (10000 km/sec) line does not appear to be affected by continuum changes. The physical conditions in the BLR and VBLR seem to be widely different.

    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

    NIRPS first light and early science: breaking the 1 m/s RV precision barrier at infrared wavelengths
    The Near-InfraRed Planet Searcher or NIRPS is a precision radial velocity spectrograph developed through collaborative efforts among laboratories in Switzerland, Canada, Brazil, France, Portugal and Spain. NIRPS extends to the 0.98-1.8 μm domain of the pioneering HARPS instrument at the La Silla 3.6-m telescope in Chile and it has achieved
