Do black holes exist? Observations at the finest resolution so far indicate that only gross deviations in the behaviour of gravity from that predicted by general relativity can invalidate the case that they do.

Stellar and Interstellar Precursor Missions
Staggering as they may seem to us, interplanetary distances are puny compared to those to reach stars. Our Solar System is located about two-thirds of the way from the center of our Milky Way GalaxyExpand
Nano-optics: Quantum light switch
Combining the strong nonlinearity of single-photon emitters with the light-focusing characteristics of metal nanowires could soon enable the realization of a single-photon transistor — a device thatExpand
Extraordinary transmission of evanescent modes through a dielectric-filled nanowaveguide
Abstract It has already been shown that extraordinary transmission through a dielectric-filled subwavelength aperture can be obtained if the dielectric constants of the cladding metal and apertureExpand
Ultra-sensitive vibrational spectroscopy of protein monolayers with plasmonic nanoantenna arrays
TLDR
A new tool based on collective excitation of plasmonic nanoantenna arrays is developed and direct detection of vibrational signatures of single protein monolayers is demonstrated and an advanced model based on nonequilibrium Green's function formalism is introduced. Expand
Effect of periodicity on the performance of surface plasmon resonance sensors based on subwavelength nanohole arrays
Abstract Surface plasmon resonance platforms, based on arrays of nanoholes on gold films, were used to detect the binding of organic and biological molecules. Optical sensors were assembled usingExpand
Optical properties of high-quality nanohole arrays in gold made using soft-nanoimprint lithography
We present a novel soft-nanoimprint procedure to fabricate high-quality sub-wavelength hole arrays in optically thick films of gold on glass substrates. We fabricate 0.5 × 0.5 mm 2 structuresExpand

Event-horizon-scale structure in the supermassive black hole candidate at the Galactic Centre
TLDR
Observations at a wavelength of 1.3 mm set a size of microarcseconds on the intrinsic diameter of Sagittarius A*, suggesting that the bulk of Sgr A* emission may not be centred on the black hole, but arises in the surrounding accretion flow. Expand
Astronomy: Light on a dark place
TLDR
A new short-wavelength radio image of Sagittarius A* has made it possible to establish the intrinsic size of Sgr A* for the first time, suggesting that its mass density is more than 10 orders of magnitude greater than any other known cosmic object, well into supermassive black hole territory.

Magnetically Driven Accretion Flows in the Kerr Metric. IV. Dynamical Properties of the Inner Disk
This paper continues the analysis of a set of general relativistic three-dimensional MHD simulations of accreting tori in the Kerr metric with different black hole spins. We focus on bound matterExpand
Fuelling active galactic nuclei
We suggest that most nearby active galactic nuclei are fed by a series of small-scale, randomly oriented accretion events. Outside a certain radius these events promote rapid star formation, whileExpand
A supermassive boson star at the galactic center
We explore whether supermassive non-baryonic stars (in particular boson, mini-boson and non-topological soliton stars) might be at the center of some galaxies, with special attention to the MilkyExpand
The Distribution and cosmic evolution of massive black hole spins
We study the expected distribution of massive black hole (MBH) spins and its evolution with cosmic time in the context of hierarchical galaxy formation theories. Our model uses Monte CarloExpand
A size of ∼1 au for the radio source Sgr A* at the centre of the Milky Way
Although it is widely accepted that most galaxies have supermassive black holes at their centres, concrete proof has proved elusive. Sagittarius A* (Sgr A*), an extremely compact radio source at theExpand
