PublicationNightside condensation of iron in an ultrahot giant exoplanet
Ultrahot giant exoplanets receive thousands of times Earth's insolation 1,2. Their high-temperature atmospheres (greater than 2,000 kelvin) are ideal...

PublicationNo surviving evolved companions of the progenitor of SN1006
TypeIa supernovae are thought to occur when a white dwarf made of carbon and oxygen accretes sufficient mass to trigger a thermonuclear explosion. The accretion...

PublicationObservation of inverse Compton emission from a long γ-ray burst
Long-duration γ-ray bursts (GRBs) originate from ultra-relativistic jets launched from the collapsing cores of dying massive stars. They are characterized by an...

PublicationOptical detection of meteoroidal impacts on the Moon
Impacts of meteoroids on the Moon should cause detectable optical flashes, but the population of objects that are big enough is very low, and hitherto no...

PublicationRapid quasi-periodic oscillations in the relativistic jet of BL Lacertae
Blazars are active galactic nuclei (AGN) with relativistic jets whose non-thermal radiation is extremely variable on various timescales 1-3. This variability...
