The merging binary black holes (BBHs) have been detected by the ground gravitational-wave observatories, but it is very difficult to detect BBHs before their mergers. Since millisecond pulsars (MSPs) are remarkable precise ‘clocks’ in Universe, they could be used to detect the hidden BBHs, if they exist in systems of BBHs. Doing so, we construct a triple system which consists of a BBH and a...
Reissener-Nordstrom and Kerr-Newman black holes in the Einstein-Maxwell theory have electric and/or magnetic charges.ThiboutDamour and Remo Ruffini studied quantum electrodynamical (QED) effect in Kerr-Newman geometries that is the Sauter-Schwinger mechanism of pair creation from charged black holes [T. Damour and R. Ruffini, Phys. Rev. Lett. 35, 463 (1975)], and proposed the mechanism for...
In my talk, I will briefly share some memories about the important role played by prof. Ruffini in some of the most important stages and scientific experiences of my career. I will speak about the time of when I was a master student in prof. Ruffini's group at La Sapienza first, and then as a PhD student in the Erasmus Mundus program. Finally, I will spend some words about the concept of...
The concept of boson stars (BSs) was first introduced by Kaup and Ruffini-Bonazzola in the 1960s. Following this, a lot of attention has been directed to the possible role of BSs in astrophysics whether as a dark matter (DM) candidate or as the less exotic alternative to different types of black holes.
Here, for the first time, we introduce a new class of compact objects as a mixture of...
With a coordinate transformation, the Schwarzschild metric in the standard coordinate can become the one in the Kerr-Schild coordinate. In this work, we derive the second post-Newtonian solutions for the test particle’s motion in the Schwarzschild spacetime under these two coordinates, and show that the calculation results for the time from the perihelion to the aphelion are different. Since...
