Publisher Correction: Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
In the version of this Article originally published the Fig. 6 y axis label read 'Mej' but should have read 'MNi'. This has now been corrected.

Spectroscopic identification of r-process nucleosynthesis in a double neutron-star merger
Observations of the transient associated with the gravitational-wave event GW170817 and γ-ray burst GRB 170817A reveal a bright kilonova with fast-moving ejecta, including lanthanides synthesized by rapid neut...

Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
Type II supernovae are the final stage of massive stars (above 8 M ⊙) which retain part of their hydrogen-rich envelope at the moment of explosion. They typically eject up to 15 M

Correction: Corrigendum: Slowly fading super-luminous supernovae that are not pair-instability explosions
Nature 502, 346–349 (2013); doi:10.1038/nature12569 In this Letter, we have identified an important error affecting Fig. 4 and Extended Data Fig. 6, as well as the values of some parameters derived from our mo...

First Results from Supernova Diversity and Rate Evolution (SUDARE) Survey at VST
Despite the key role played by Supernovae (SNe) in discovering the accelerating expansion of the Universe, there are still fundamental questions to answer about their progenitor systems and explosion mechanism...

Supernovae as Cosmological Probes
I review the use of SN Ia as distance indicators for measuring H 0, the Hubble constant, and the expansion history of the Universe. Most current estimates of H 0 are in the range 74–76

A New Search for Variability-Selected Active Galaxies Within the VST SUDARE-VOICE Survey: The Chandra Deep Field South and the SERVS-SWIRE Area
This work makes use of the VST observations to select variable sources. We use also the IR photometry, SED fitting and X-ray information where available to confirm the nature of the AGN candidates. The IR data...

Variability-Selected AGNs in the VST-SUDARE Survey of the COSMOS Field
Variability is characteristic of active galaxies; luminosity variations generally occur at all wavelengths, affecting both continuum and line emission, with timescales and amplitudes depending on the wavelengt...

Slowly fading super-luminous supernovae that are not pair-instability explosions
Observations of two slow-to-fade super-luminous supernovae are reported; both show relatively fast rise times and blue colours, which are incompatible with pair-instability models.

Five supernova survey galaxies in the southern hemisphere. II. the supernova rates
Based on the database compiled in the first article of this series, with 56 SN events discovered in 3838 galaxies of the southern hemisphere, we compute the rate of supernovae (SNe) of different types along th...

A low-energy core-collapse supernova without a hydrogen envelope
Theory suggests that stars with initial masses greater than 25–30 times that of the Sun end their stellar lives as Wolf–Rayet stars, becoming hydrogen-deficient by rapidly losing mass through strong stellar wi...

A giant outburst two years before the core-collapse of a massive star
When a bright optical transient was discovered in galaxy UGC 4904 in October 2004 the signs were that it was big enough and bright enough to be a supernova. Further work suggested that it was not quite on that...

An optical supernova associated with the X-ray flash XRF 060218
A link between long γ-ray bursts (GRBs) and supernovae has been established, but whether there is a similar relationship between the weaker and softer X-ray flashes and supernovae is unclear. GRB/XRF 060218, s...

The Rate and the Origin of Type Ia SNe in Radio Galaxies
An analysis of type Ia supernova (SNIa) events in early type galaxies from the Cappellaro et al. [6] database provides strong evidence that the rate of type Ia supernovae (SNe) in radio-loud galaxies is about ...

Type IA Supernovae: Constraints For The Progenitor Scenario
The use of type Ia Supernovae (SNe) as distance indicators lead two groups to the surprising conclusion that the expansion of the Universe is accelerated [1, 2]. This result relies on the assumption that the p...
