    The high energy Universe at ultra-high resolution: the power and promise of X-ray interferometry

    We propose the development of X-ray interferometry (XRI), to reveal the Universe at high energies with ultra-high spatial resolution. With baselines which can be accommodated on a single spacecraft, XRI can re...

    Accretion in strong field gravity with eXTP

    In this paper we describe the potential of the enhanced X-ray Timing and Polarimetry (eXTP) mission for studies related to accretion flows in the strong field gravity regime around both stellar-mass and superm...

    The far-ultraviolet signature of the ‘missing’ baryons in the Local Group of galaxies

    The number of baryons detected in the low-redshift (z < 1) Universe is far smaller than the number detected in corresponding volumes at higher redshifts. Simulations1,2,3 of the formation of structure in the Univ...
