    Segue 2 Recently Collided with the Cetus-Palca Stream: New Opportunities to Constrain Dark Matter in an Ultra-faint Dwarf
    Stellar streams in the Milky Way are promising detectors of low-mass dark matter (DM) subhalos predicted by ΛCDM. Passing subhalos induce perturbations in...

    Sensitivity of the Cherenkov Telescope Array to TeV photon emission from the Large Magellanic Cloud
    A deep survey of the Large Magellanic Cloud at ~0.1-100 TeV photon energies with the Cherenkov Telescope Array is planned. We assess the detection prospects...

    Short time-scale fluctuations in the difference light curves of QSO 0957+561A,B: microlensing or noise?
    From optical R-band data of the double quasar QSO 0957+561A,B, we made two new difference light curves (with an overlap of about 330d between the time-shifted...

    Sociology and hierarchy of voids: A study of seven nearby CAVITY galaxy voids and their dynamical CosmicFlows-3 environment
    Context. The present study addresses a key question related to our understanding of the relation between void galaxies and their environment: the relationship...

    Stellar splashback: the edge of the intracluster light
    We examine the outskirts of galaxy clusters in the C-EAGLE simulations to quantify the 'edges' of the stellar and dark matter distribution. The radius of the...
