New BV RI photometry and optical spectroscopy of the Type IIp supernova 2004dj in NGC 2403, obtained during the first year since discovery, are presented. The...
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...
Long suspected on theoretical grounds and supported by tantalising observational evidence, the connection between supernovae and gamma-ray bursts was definitely...
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...
The local group symbiotic star population and its tenuous link with type Ia supernovae
Context. Binary stars are gravitationally bound stellar systems where the evolution of each component can significantly influence the evolution of its companion...
