    Fundamental physics with ESPRESSO: Towards an accurate wavelength calibration for a precision test of the fine-structure constant
    Observations of metal absorption systems in the spectra of distant quasars allow one to constrain a possible variation of the fine-structure constant throughout...

    Galactic angular momentum in the IllustrisTNG simulation - I. Connection to morphology, halo spin, and black hole mass
    We use the TNG100 simulation of the IllustrisTNG project to investigate the stellar specific angular momenta (j *) of ~12 000 central galaxies at z = 0 in a...

    Galactic wind X-ray heating of the intergalactic medium during the Epoch of Reionization
    The diffuse soft X-ray emissivity from galactic winds is computed during the Epoch of Reionization (EoR). We consider two analytic models, a pressure-driven...

    Galaxies at z>7: Probing galaxy formation with the new generation of NIR Instruments
    We present the results obtained from our deep survey of lensing clusters aimed at constraining the abundance of star-forming galaxies at z ˜ 6-11. Lensing...

    Galaxy Counts at 24 μm in the SWIRE Fields
    This paper presents galaxy source counts at 24 μm in the six Spitzer Wide-field InfraRed Extragalactic (SWIRE) fields. The source counts are compared to counts...

    Galaxy pairs and clusters in a lambda CDM universe: Bridging observation and simulation
    I use computer simulations to examine the evolution of close galaxy pair counts and the formation of galaxy clusters. I show that the evolution of the close...

    Galaxy size trends as a consequence of cosmology
    We show that recently documented trends in galaxy sizes with mass and redshift can be understood in terms of the influence of underlying cosmic evolution; a...

    Gas and dust properties in the afterglow spectra of GRB 050730
    We present early WHT ISIS optical spectroscopy of the afterglow of gamma-ray burst GRB 050730. The spectrum shows a DLA system with the highest measured...
