Among the main science cases that have motivated the proposal of CUBES, a new high-resolution spectrograph for the Very Large Telescope at the European Southern Observatory, there is the study and the characterisation of the nucleosynthesis of beryll

We analyse high resolution spectra of two classical novae that exploded in the Small Magellanic Cloud. $^7$Be II resonance transitions are detected in both ASASSN-19qv and ASASSN-20ni novae. This is the first detection outside the Galaxy and confirms

We report on the spectral confirmation of 18 QSO candidates from the "QUasars as BRIght beacons for Cosmology in the Southern hemisphere'' survey (QUBRICS), previously observed in the optical band, for which we acquired new spectroscopic data in the

We have used the SAC (self absorption curve) method to analyse the fluxes of optical Fe II emission lines published by Crawford et al. (1999).Certain lines have considerable self absorption. Information about both the populations of the upper and the

We have identified and measured the accurate strengths of Bowen fluorescence lines of O III and N III in the spectra of the Symbiotic Nova RR Telescopii. Altogether 29 O III lines, some of them newly identified, have been measured. After re‐determi
