The Birth of a Relativistic Jet Following the Disruption of a Star by a Cosmological Black Hole
A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet fortuitously aligns with our line of sight, the overall brightness is Doppler boosted by several orders of magn...

An asymmetric electron-scattering photosphere around optical tidal disruption events
A star crossing the tidal radius of a supermassive black hole will be spectacularly ripped apart with an accompanying burst of radiation. A few tens of such tidal disruption events have now been identified in ...

Infant-phase reddening by surface Fe-peak elements in a normal type Ia supernova
Type Ia supernovae are thermonuclear explosions of white dwarf stars. They play a central role in the chemical evolution of the Universe and are an important measure of cosmological distances. However, outstan...

The electron-capture origin of supernova 2018zd
In the transitional mass range (~8–10 solar masses) between white dwarf formation and iron core-collapse supernovae, stars are expected to produce an electron-capture supernova. Theoretically, these progenitor...

Distinguishing Tidal Disruption Events from Impostors
Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant supermassive black holes (SMBHs) in...

Optical-Ultraviolet Tidal Disruption Events
The existence of optical-ultraviolet Tidal Disruption Events (TDEs) could be considered surprising because their electromagnetic output was originally predicted to be dominated by X-ray emission from an accret...

New regimes in the observation of core-collapse supernovae
Core-collapse supernovae (CCSNe) mark the deaths of stars more massive than about eight times the mass of the Sun and are intrinsically the most common kind of catastrophic cosmic explosions. They can teach us...

A new class of flares from accreting supermassive black holes
Accreting supermassive black holes (SMBHs) can exhibit variable emission across the electromagnetic spectrum and over a broad range of timescales. The variability of active galactic nuclei (AGNs) in the ultrav...

Energetic eruptions leading to a peculiar hydrogen-rich explosion of a massive star
Observations of an event (several energetic eruptions leading to a terminal explosion that is surprisingly hydrogen-rich) with the spectrum of a supernova do not match with other observations of supernovae.

Optical emission from a kilonova following a gravitational-wave-detected neutron-star merger
Optical to near-infrared observations of a transient coincident with the detection of the gravitational-wave signature of a binary neutron-star merger and a low-luminosity short-duration γ-ray burst are presen...

Hydrogen-Rich Core-Collapse Supernovae
Hydrogen-rich core-collapse supernovae, known as “Type II” supernovae , are the most common type of explosion realized in nature. They are defined by the presence of prominent hydrogen lines in their spectra. ...

Erratum: A strong ultraviolet pulse from a newborn type Ia supernova
Nature 521, 328–331 (2015); doi:10.1038/nature14440 In this Letter, the superscript in the ultraviolet luminosity was listed incorrectly as ‘−41’ rather than ‘41’ in the last sentence of the second paragraph f...

A strong ultraviolet pulse from a newborn type Ia supernova
Observations of declining ultraviolet emission from a type Ia supernova within four days of the explosion are as expected if material ejected by the supernova collided with a companion star, supporting the sin...
