    GRB 060121: Implications of a Short-/Intermediate-Duration γ-Ray Burst at High Redshift
    Since the discovery of the first short-population γ-ray burst (GRB) afterglows in 2005, the handful of observed events have been found to be embedded in nearby...

    GRB 080913 at Redshift 6.7
    We report on the detection by Swift of GRB 080913, and subsequent optical/near-infrared follow-up observations by GROND, which led to the discovery of its...

    GRB 081007 and GRB 090424: The Surrounding Medium, Outflows, and Supernovae
    We discuss the results of the analysis of multi-wavelength data for the afterglows of GRB 081007 and GRB 090424, two bursts detected by Swift. One of them, GRB...

    Green's Functions for Far-Side Seismic Images: A Polar-Expansion Approach
    We have computed seismic images of magnetic activity on the far surface of the Sun by using a seismic-holography technique. As in previous works, the method is...

    GTC Follow-up Observations of Very Metal-poor Star Candidates from DESI
    The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of...

    GTC/CanariCam Deep Mid-infrared Imaging Survey of Northern Stars within 5 pc
    In this work we present the results of a direct imaging survey for brown dwarf companions around the nearest stars at the mid-infrared 10 micron range (λ c = 8...
