    The evolution of luminous red nova AT 2017jfs in NGC 4470
    We present the results of our photometric and spectroscopic follow-up of the intermediate-luminosity optical transient AT 2017jfs. At peak, the object reaches...

    The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
    Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of...

    The GRB 060218/SN 2006aj event in the context of other gamma-ray burst supernovae
    The supernova SN 2006aj associated with GRB 060218 is the second-closest GRB-SN observed to date (z=0.033). We present Very Large Telescope, Liverpool Telescope...

    The Highly Energetic Expansion of SN 2010bh Associated with GRB 100316D
    We present the spectroscopic and photometric evolution of the nearby (z = 0.059) spectroscopically confirmed Type Ic supernova, SN 2010bh, associated with the...

    The Hubble diagram of type Ia supernovae as a function of host galaxy morphology
    We present new results on the Hubble diagram of distant type Ia supernovae (SNeIa) segregated according to the type of host galaxy. This makes it possible to...

    The Hydrogen-poor Superluminous Supernovae from the Zwicky Transient Facility Phase I Survey. I. Light Curves and Measurements
    During the Zwicky Transient Facility (ZTF) Phase I operations, 78 hydrogen-poor superluminous supernovae (SLSNe-I) were discovered in less than 3 yr...

    The impact of natal kicks on galactic r-process enrichment by neutron star mergers
    We study galactic enrichment with rapid neutron capture (r-process) elements in cosmological, magnetohydrodynamical simulations of a Milky Way-mass galaxy. We...

    The jet feedback mechanism: from supernovae to clusters of galaxies
    I will describe the roles of jets in several quite different astrophysical systems. These include exploding core collapse supernovae, expelling common envelopes...
