‘Hairy’ black holes

Every year, the prestigious American Physical Society (APS) issues a list of the most important articles published in the journals the APS is an editor for. For 2016, as one would expect, it was the gravitational waves discovery by the LIGO interferometer that prevailed.

New frontiers for the hunt of the axion

During the past decades, a plethora of experimental results has firmly established that strong interaction phenomena in particle physics are correctly described by a theory known as Quantum Chromo Dynamics (QCD).

The ‘variable’ constant

One of the most fascinating predictions of quantum electrodynamics (QED), is the existence of a state of minimum energy, the vacuum state, which is full of particles, namely the particle-antiparticle pairs that exist for a very short time and are therefore called virtual.

The neutrons poker

Take a look at your hand, while breathing some air: what are they made of? Our bodies, and more generally, matter is made of atoms, which, in turn, are made up of a small and dense nucleus orbited by electrons.

LIGO’s second time

On December 26, 2015, LIGO's detectors caught a second robust signal from two black holes in their final orbits and then their coalescence into a single black hole.

The axion hunt is still on

Among the most troubling problems for physicists, the nature of dark matter is certainly at the top of the list. It’s a matter of numbers: this elusive matter contributes for about a quarter to the total energy of the universe, a huge figure considering only a thin 5% comes from ordinary matter and radiation.
