    Relative lithium abundances in pre-main-sequence spectroscopic binaries
    We present a study of the lithium abundance of five pre-main sequence (PMS) double-lined binaries. These binaries are composed of weak-lined T Tauri stars...

    Resolving the kinematical structure within the nuclear starburst of NGC 253
    We present high spectral and spatial resolution spectroscopy of the nuclear starburst region of the galaxy NGC 253. Two slit positions, matching the major and...

    Revised Parameter Estimates For The Most Metal-Poor Candidates In SDSS-I And SEGUE
    There are several hundred thousand R = 2000 stellar spectra reported in the final public release of the Sloan Digital Sky Survey (SDSS-I) and the continuing...

    Rocky exoplanets and their host stars may have similar composition
    Newly formed stars have protoplanetary discs around them. A fraction of the material in the disc condenses into planet-forming chunks, and the rest finally...

    Role of ISM/IGM Energy Balance in Structure Formation and Evolution of Galaxies
    Investigating the thermal and non-thermal processes in galaxies is vital to understand their evolution over cosmic time. This can best be studied by combining...

    Satellite galaxies can carry on forming stars when they pass close to their parent galaxies
    Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the...

    SDSS-IV MaNGA: Spatial Evolution of Star Formation Triggered by Galaxy Interactions
    Galaxy interaction is considered a key driver of galaxy evolution and star formation (SF) history. In this paper, we present an empirical picture of the radial...

    Searching for emission-line galaxies: The UCM survey
    We are carrying out a long-term project with the main purposes of finding and analyzing low metallicity galaxies. A very small number of very low metallicity...

    Searching for High Redshift Clusters
    Distant clusters of galaxies provide a powerful method to study the formation and evolution of galaxies, and large scale structure of the Universe. However, the...
