GRBSpec and GRBPhot are two databases designed for the storage and analysis of gamma-ray burst (GRB) data. GRBSpec is devoted to spectroscopic observations, GRBPhot to photometric data. Both databases have a detailed search engine and offer online graphical tools for plotting and data analysis. They aim to publicly share these specialised data among the astronomical community and provide quick online measurements and plots. The databases can be accessed through http://grbpsec.iaa.es and http://grbphot.iaa.es, respectively. As of November 2020, the database already contained 2013 files belonging to 810 spectra of 268 different GRBs.
GATOS (GTC Astrophysical Transient Octuple-channel imaging Spectrograph) is a multi-channel imager and spectrograph capable of simultaneously obtaining images of the same field in 8 optical and near-infrared bands or alternatively performing spectroscopy covering the range between 3500 and 23500 Angstrom in a single shot at a resolving power of R ∼ 4000. State-of-the-art detectors envisioned for this instrument will have negligible readout times and be able to perform high-time-resolution observations. An integral-field mode covering the same range simultaneously will be a crucial element of the design. In its current design, the integral-field unit covers a field of 12" × 8" with 0.6" slitlets. Finally, we aim to include a unique spectropolarimetry unit that will give GTC the first broad-band spectropolarimeter on a 10 m class telescope. The design is an evolution of the OCTOCAM concept that was selected to be built at Gemini, and is now known as SCORPIO.
