A new approach to measure the mass of intergalactic black holes

Researchers suggested that among bright X-ray flares that continue for a few years, some can be caused by tidal gravitational disruption of a star which passed too close to a super massive black hole. Recently, a team led by Elena Seifina found something interesting while looking at the event called “Swift J1644 + 57”.

New quantum oscillations in graphene

To observe quantum oscillation, usually cryogenic temperatures are required. However, a research team led by R. Krishna Kumar from University of Manchester showed that graphene superlattices support a different type of quantum oscillation that does not rely on Landau quantization.

Measuring gravitational waves to see inside stars

The observation of supernovae gives us very interesting insight of how our universe works. In particular, the type II supernovae are looked closely. They are what happens when a massive star experiences a rapid collapse. This triggers a massive explosion that blows off the outer layers of the star, leaving behind a remnant neutron star.

New progress in Quantum Machine Learning

In a recent study, an international team of researchers lead by Jacob Biamonte from Skoltech/IQC proposed a review of the actual status of classical machine learning and quantum machine learning. In their paper, they found it is reasonable to postulate that quantum computers may outperform classical computers on machine learning tasks.

Water Droplets Superpropulsion

Recently, a team of researchers led by Christophe Raufaste has found that drops ejected by an oscillating surface can at times travel faster than the surface that ejected them. In their paper published in the journal Physical Review Letters, the team describes experiments they conducted by flinging water from a superhydrophobic surface. More precisely, they investigate the behavior of droplets and soft elastic objects propelled with a catapult.

Supernova observations helping understand general relativity

Recent research just confirms this theory that accelerating expansion of the Universe may not be real, but could just be an apparent effect of the rotating galaxies moving in different directions. A new study proposed a model of our universe with no dark energy and find their result to be very slightly better than the fit to the standard dark energy model.

Solving the mystery of white dwarf’s mass

The study of the cosmos gives us a lot of keys to understand the dynamic of our universe from the big objects to the smallest ones. Every new step is important like when we calculated more accurately the mass of a white dwarf star.

Recent advances in Quantum approach to Image processing

Quantum image processing (QIP) is an emerging sub-discipline that is focused on extending conventional image processing tasks and operations to the quantum computing framework. It is primarily devoted to utilizing quantum computing technologies to capture, manipulate, and recover quantum images in different formats and for different purposes.

The race for Quantum Supremacy

The quantum computing revolution is a serious subject since the 1980s. At that time, theorists realized that a computer based on quantum mechanics had the potential to vastly outperform ordinary, or classical, computers at certain tasks. There is now a race for the so-called “quantum supremacy”, to reach the capabilities no conventional computer can match, and Google wants to be the first.

Jupiter’s Insane Auroras are Powered by an Energy Source Nobody can Explain

The dynamic dance between the Earth’s magnetic field and the solar wind – the aurora – is said to be one of the most magnificent sites we can observe here on Earth.

UV emission linked to Supernova explosion mechanism

Supernovae are an explosion of a massive supergiant star which may shine with the brightness of 10 billion suns! By observing these supernovas in galaxies, it is possible to unlock mysteries about black holes, the origin of metals such as gold and the dynamic of the universe. Yet today, astronomers are looking carefully at these phenomena trying to describe them with accuracy.

Quantum memories for a quantum internet network

Quantum networks built from optical fiber-linked quantum nodes open manifold opportunities like high-speed quantum cryptography networks, large scale quantum computers and quantum simulators. However, the requirement for a scalable quantum node technology is a simple and reliable quantum memory system.

Levitating and self-organizing droplets

Fluid dynamics is an ongoing topic with many surprising aspects. One of these is the Leidenfrost effect. It comes from the name of the German scientist who described it for the first time: Johann Gottlob Leidenfrost. It occurs when a liquid, in contact with an object significantly warmer than the liquid’s boiling temperature, produces a vapor layer which surrounds the object and thus isolates it from the direct thermal exchanges with the object.
