NGC 7293, the Helix nebula, represents one of the rare instances in which theoretical predictions of stellar evolution can be accurately tested against observations since the precise parallax distance and the velocity and proper motion of the star are well known. We present numerical simulations of the formation of the Helix PN that are fully

Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of a white dwarf by an intermediate-mass black hole, a supernova shock breakout, or a binary neutron star merger. We present the X-ray light curve and spectrum as well as deep optical imaging

Relic galaxies are extremely compact early-type objects that have failed to accrete an extended envelope of stars. We observed the relic galaxy NGC 1277 with the integral field George and Cynthia Mitchel spectrograph (GCMS). The observations also include the regular early-type galaxy NGC 1278, which is used for comparison. We obtained resolved

The IAC in Tenerife is collaborating with an international consortium involving the University of Hawaii, MorphOptic (USA), Dynamical Intelligent Structures (DiSL, Canada) and two institutes in Lyon (CRAL@CNRS + INSA; France), to design the future $\geq$40m ExoLife Finder (ELF), an optical hybrid interferometer telescope. The objectives of ELF are

We present the results regarding the analysis of an intensive monitoring of the Active Galactic Nucleus (AGN) NGC 7469. We observed the source for 4 months with almost daily cadence in the ugriz bands, using the IO:O on the Liverpool Telescope. We measured the lags with respect to the u band and found a clear change in the lag spectrum between the

The large amounts of astrophysical data being provided by existing and future instrumentation require efficient and fast analysis tools. Transfer learning is a new technique promising higher accuracy in the derived data products, with information from one domain being transferred to improve the accuracy of a neural network model in another domain
