    A new reference catalogue for the very metal-poor Universe: +150 OB stars in Sextans A
    Local Group (LG) very metal-poor massive stars are the best proxy for the First Stars of the Universe and fundamental to modelling the evolution of early...

    A New spectral stellar library for population synthesis
    A new spectral stellar library designed to be included in population synthesis models is presented. The library, which has been obtained at the INT 2.5 m...

    A New Stellar Library in the K Band
    Stellar population synthesis models are crucial for the understanding of the large amount of data which is being gathered for galaxies at low and high redshift...

    A new stellar library in the region of the CO index at 2.3 μm. New index definition and empirical fitting functions
    Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength...

    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 technique for decoupling the host and nuclear spectra of type I AGNs using integral field spectroscopy
    We have developed a new technique to decouple the spectra of the host and the nucleus of type I AGNs using integral field spectroscopy (IFS) data. The technique...

    A new tidal scenario for double bar formation
    Double bars make up a significant fraction of barred galaxies. We propose a new formation scenario for double bars that involves tidal interactions. We...

    A New View of the Dwarf Spheroidal Satellites of the Milky Way from VLT FLAMES: Where Are the Very Metal-poor Stars?
    As part of the Dwarf galaxies Abundances and Radial-velocities Team (DART) program, we have measured the metallicities of a large sample of stars in four nearby...

    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...
