PublicationA Be-type star with a black-hole companion
Stellar-mass black holes have all been discovered through X-ray emission, which arises from the accretion of gas from their binary companions (this gas is...

PublicationA broadband thermal emission spectrum of the ultra-hot Jupiter WASP-18b
Close-in giant exoplanets with temperatures greater than 2,000 K (`ultra-hot Jupiters') have been the subject of extensive efforts to determine their...

PublicationA candidate super-Earth planet orbiting near the snow line of Barnard's star
Barnard's star is a red dwarf, and has the largest proper motion (apparent motion across the sky) of all known stars. At a distance of 1.8 parsecs1, it is the...

PublicationA dark jet dominates the power output of the stellar black hole Cygnus X-1
Black holes undergoing accretion are thought to emit the bulk of their power in the X-ray band by releasing the gravitational potential energy of the infalling...

PublicationA dense 0.1-solar-mass star in a 51-minute-orbital-period eclipsing binary
Of more than a thousand known cataclysmic variables (CVs), where a white dwarf is accreting from a hydrogen-rich star, only a dozen have orbital periods below...

PublicationA dust-obscured massive maximum-starburst galaxy at a redshift of 6.34
Massive present-day early-type (elliptical and lenticular) galaxies probably gained the bulk of their stellar mass and heavy elements through intense, dust...

PublicationA giant planet candidate transiting a white dwarf
Astronomers have discovered thousands of planets outside the Solar System 1, most of which orbit stars that will eventually evolve into red giants and then into...

PublicationA gravitational-wave standard siren measurement of the Hubble constant
On 17 August 2017, the Advanced LIGO and Virgo detectors observed the gravitational-wave event GW170817—a strong signal from the merger of a binary neutron-star...
