    Hubble constant and nuclear equation of state from kilonova spectro-photometric light curves
    The merger of two compact objects of which at least one is a neutron star is signalled by transient electromagnetic emission in a kilonova (KN). This event is...

    Hubble spectroscopy of LB-1: Comparison with B+black-hole and Be+stripped-star models
    Context. LB-1 (alias ALS 8775) has been proposed as either an X-ray dim B-type star plus black hole (B+BH) binary or a Be star plus an inflated stripped star...
