    Observing the polarized microwave sky: 10 years of the QUIJOTE experiment
    I will review the status of the QUIJOTE (Q-U-I JOint TEnerife) experiment, a project led from the IAC with the aim of characterising the polarisation of the...

    A bright triple transient that vanished within 50 min
    We report on three optically bright, ~16th mag, point sources within 10 arcsec of each other that vanished within 1 h, based on two consecutive exposures at...

    A Fast and Very Accurate Approach to the Computation of Microlensing Magnification Patterns Based on Inverse Polygon Mapping
    A new method of calculating microlensing magnification patterns is proposed that is based on the properties of the backward gravitational lens mapping of a...

    A high-resolution investigation of the multiphase ISM in a galaxy during the first two billion years
    We have carried out the first spatially resolved investigation of the multiphase interstellar medium (ISM) at high redshift, using the z = 4.24 strongly lensed...

    A Large Brightness Enhancement of the QSO 0957+561 A Component
    We report an increase of more than 0.2 mag in the optical brightness of the leading image (A) of the gravitational lens Q0957+561, detected during the 2000...

    A Mass Model for the Lensing Cluster SDSS J1004+4112: Constraints from the Third Time Delay
    We have built a new model for the lens system SDSS J1004+4112 including the recently measured time delay of the fourth quasar image. This time delay has a...

    A New Einstein Cross Gravitational Lens of a Lyman-break Galaxy
    We report the study of an “Einstein Cross” configuration first identified in a set of HST images by Cerny et al. Deep spectroscopic observations obtained at the...

    A new step forward in realistic cluster lens mass modelling: analysis of Hubble Frontier Field Cluster Abell S1063 from joint lensing, X-ray, and galaxy kinematics data
    We present a new method to simultaneously and self-consistently model the mass distribution of galaxy clusters that combines constraints from strong lensing...

    A new VLA/e-MERLIN limit on central images in the gravitational lens system CLASS B1030+074
    We present the new Very Large Array 22 GHz and extended Multi-Element Remote-Linked Interferometer Network 5 GHz observations of CLASS B1030+074, a two-image...
