Discovery of unusual spindle-like galaxies

Galaxies can be really peculiar and astronomers create especially two classifications for these strange objects: the Messier catalog or the New General Catalog. These galaxies can host ultraluminous X-rays or present funny shape like the Whirlpool Galaxy or “cigar galaxy” also named prolate rotator. Until recently this type of “cigar galaxy” was very rare and their formation was a mystery. However, a study describing new findings was published in the journal Astronomy.

New findings to create better permanent magnet

Magnets are atomic powered. The classical explanation of the magnetic phenomenon is based on the spin alignment. Permanent magnets have their spin aligned all the time. In a recent work, a team from the Lawrence Livermore National Laboratory from California proposed a new efficient permanent magnet, SmCoNiFe3. Using first-principles electronic-structure calculations, the team found that their new alloy has very promising magnetic properties and could replace SmCo5 or neodymium magnets in various applications.

Flow reversal in a quantum system

In Classical Physic, thermodynamic laws determine what will be the flow of matter and energy. Basically, it can be summarized by the famous maxim: “Nature abhors vacuum”. However, in quantum materials, thermodynamical concepts seem to need to be revisited. There, states of matter can be set into a coherent superposition. When a classical observer measures a nanoscale system, this interaction destroys most of the coherence inside the system and alters its dynamical response.

Neutron Star Collision Lights Up the Sky

Neutron stars – the end state of stars sustained by the degeneracy pressure of neutrons – are not truly understood. The collision of two such stars is thought to bring clarity to our understanding – which up until now is only inferred from the observed electromagnetic (EM) radiation and/or pulses from the neutron star and surrounding material.

Pilot Wave Theory Explains EM Drive

The EM drive – a radio frequency (RF) resonant cavity thruster – appears to produce an ‘impossible’ thrust. Impossible – in that it apparently violates Newtons third law of motion: “For every action, there is an equal and opposite reaction.” Now in a recent paper by a group of Portuguese physicists, led by Prof. Jose Croca from the Center for Philosophy of Sciences at the University of Lisbon, present a possible explanation for this observed ‘impossible’ thrust.

Solving Kepler’s Most Enigmatic Find

In September 2015, an amateur astronomer D. M. LaCourse and Tabetha Boyajian, an assistant professor, have discovered the star KIC 8462852 using the public data from the Kepler telescope. Situated in the cluster NGC 6866, this star called “Tabby’s Star” is very particular due to a significant instant dimming that can be due to large irregular objects transiting.

Building the longest underground experiment to study the neutrinos

Neutrinos are one of the fundamental particles which make up the universe. They are also one of the least understood. One of the most promising experiments is the Deep Underground Neutrino Experiment called DUNE. This facility will use two complex buildings. One at Fermilab will produce a controlled beam of neutrinos produced by smashing a proton beam into a target. The second is a detector 1,300km away at the Sanford Underground Research Facility in South Dakota.

A new confirmation of the muonic value of the proton radius

Accurate knowledge of the radius of the proton is essential, not only for understanding its structure. Thus, the study of the hydrogen atom has been at the heart of the development of modern physics. This year, a new measurement was done on the proton radius and the result is in good agreement with the muonic value and with the holographic solution proposed by Nassim Haramein.

Unexpected gas dynamic in merging clusters of galaxies

Clusters of galaxies are still growing through mergers and the energy involved is pretty huge. Strong shocks, rapid rotation, and turbulence are produced in the gas. The dynamics of merging clusters can be studied using an idealized problem: the collision of two spherical, self-gravitating clusters. One of this interesting event can be seen in Abell 1033, a system located about 1.6 billion light years from Earth. In this region, astronomers have found evidence for a faded electron cloud “coming back to life,” much like the mythical phoenix, after two galaxy clusters collided.

New nanomaterial for energy conversion

Intensive research has focused on converting solar energy to provide clean chemical fuels like hydrogen. A promising solution comes from converting photon energy to hydrogen using a semiconductor material. One of the biggest difficulties in this process comes with the harvesting of photon energy across the wide solar spectrum.

Heavy elements could show the link between Quantum Mechanics and Relativity

Studying exotic elements of the periodic table, Florida State University researchers found a very surprising phenomenon. It seems the heaviest and rarest elements don’t follow the rules of quantum mechanics but instead the theory of relativity of Einstein!

New imaging technique with terahertz radiations

Recently, electromagnetic radiation in the terahertz (THz) frequency range has emerged as one of the most promising imaging techniques for a variety of applications in science and engineering. The potential and suitability of the THz technology for practical applications such as the nondestructive testing field has been released by the recent progress in producing efficient sources and detectors. Thanks to the development of ultra-fast components in both photonics and electronics, the situation is evolving rapidly.

New progress toward quantum telecommunications

The ability to generate entangled photons is a key prerequisite for several quantum applications like quantum information processing, quantum repeaters, or quantum cryptography. In particular, in the implementation of long distance quantum communication, as a matter of example for fiber-based quantum key distribution, it becomes compulsory to employ low loss transmission channels.

Nuclear activity of black holes

Gradually as the observing tools are improving, astronomers confirm the existence of black hole at the center of astronomical events. Recently, a team lead by Cristina Ramos Almeida studied the material surrounding accreting supermassive black holes and its connection between the active galactic nucleus and its host galaxy. They looked closely to local active galactic nuclei carried out in the infrared and X-ray regimes.
