1963年,罗伊-克尔教授发现了一一个爱因斯坦广义相对论方程中旋转物体的精确解:“这 个数学解 - ICRANet主任雷莫-鲁菲尼教授回忆到 - 它的应用允许我们在物理学领域,天文 和相对论天体物理学得到本质上的巨大提高:它的应用拓展到微观物理的基本粒子,如从电 子的结构到黑洞的天体物理学,当出现在一一个恒星演化结束时,达到在宇宙中最高能的过 程,如伽玛暴和活动星系核,在黑洞和极大黑洞,高达数十亿倍我们的太阳的亮度,它斗占 主导地位。”这就是雷莫-鲁菲尼与约翰-惠勒推导用过的克尔数学解,引入它来描述基本的 物理过程,给它们命名为“黑洞”。”黑洞“一一词被翻译成全世界所有的不同语言。(Physics Today, 30, 1971). 从那时起,克尔解引出了无数的科学发展,这些科学发展成就了今天的 Crafoord Prize.
这些主题随后被Blandford和Znajek (MNRAS, 179, 433, 1977)详细研究,它们的研 究是从鲁菲尼的Wilson 工作(Phys. Rev. D 12, 2959,1975)而发展的。
2006年,罗伊-克尔在每三年在不同国家举行的国际相对论天体物理大会上被授予马歇尔- 格罗斯曼奖(见相关维基百科和ICRANet的MG11奖项手册ICRANet booklet on MG11 Award)。
罗伊克尔教授曾经在ICRANet的IRAP PhD项目课程上授课。IRAP PhD项目首个由六个欧洲国家(德国、意大利、瑞典和法国等)参与,由ICRANet创建并有尼斯大学进行国际协调的国际联合博士项目。
2016年1月30日星期日,ICRANet所址对外开放,在上午十点到十三点之间会有罗伊-克尔通过Skype视频参与的会议。




近期发表的论文

Neutron-Star–Black-Hole Binaries Produced by Binary-Driven Hypernovae
Chris L. Fryer, F. G. Oliveira, J. A. Rueda, and R. Ruffini
Phys. Rev. Lett. 115, 231102 – Published 4 December 2015

It seems that the formation of a stellar mass BH does not occur directly from the collapse of a single massive star but instead it follows a much longer path in a sequence of events marked by a succession of processes of gravitational collapse, and finally leading to the actual birth of a BH: 1) the star of larger mass is evolving on a time scale much shorter in a first process of gravitational collapse, leading to a SN and the formation of a NS; 2) the binary system composed of a NS and a massive star evolves toward a binary system with a shorter and shorter orbital period, until also the second massive star explode in a SN; 3) in this process, a second NS is formed and part of the material expelled by the SN is engulfed in the accretion on the first NS; 4) this accretion can lead the accreting NS to reach its critical mass and form a BH, and during this induced gravitational collapse (IGC) process, a GRB is emitted.

The details of this complex astrophysical process have been studied and developed in a group of astrophysicists, theoretical physicists, and experts in general relativity working with the most advanced numerical computational techniques in the ICRANet Seats.
It was not clear if, after the violent SN explosion with a large loss of mass, the NS (remnant of the SN) and the just born BH could indeed survive as a binary system. From the traditional work on binary systems, it was well known that, if a SN explosion leads to a loss of mass larger than 50% of the initial total mass of the system, this would become unbound leading to the expulsion of the stars in opposite directions. In a paper just published in the prestigious scientific journal "Physical Review Letters" http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.115.231102, Fernanda Gomez Oliveira, a young Brazilian student of the IRAP-PhD in Rome, with Chris Fryer of LANL and her directors of PhD thesis Jorge Rueda and Remo Ruffini, have shown that this result of classical astronomy is actually superseded when relativistic conditions are duly taken into account. They have shown explicitly that in this IGC phenomenon a new binary system composed by a NS and a BH can be formed even in the case when the mass ejected is larger than 50%! One of the most fascinating conclusions is that the orbits of these new binary systems, in view of the emission of gravitational waves, will shrink with time and, in some ten thousand years, will lead to a necessary coalescence of the two objects. This new phenomenon will culminate in the formation a single new BH of approximately five solar masses. These authors predict that a new GRB of extremely short duration will then be emitted and, for this reason, they have baptized such a new system as "ultrashort GRB". This is a totally new possibility predicted by the IGC paradigm: for the first time, in the field of relativistic astrophysics, it is proposed not only the explanation of the GRB phenomena but that a GRB can lead itself to another GRB.

新的博士论文答辩和学位

Maxime Enderli, "Binary Progenitors of GRBs in the Fireshell Model", 2015年 12月9日在罗马智慧大学答辩
Commission members: Antonio Capone (University of Rome "la Sapienza"), Massimo Della Valle (INAF Capodimonte Observatory), Luigi Stella (INAF Rome Observatory)

The works presented in this thesis share a common scope. Each of them plays a part in the establishment of a new classification of gamma-ray bursts based on results obtained with the alternative fireshell model. Due to the extreme nature of GRBs, it is noteworthy that a better understanding of these phenomena may yield important developments in the fields of relativistic astrophysics and cosmology.
According to the classification that we obtain, all GRBs – short and long, energetic and less energetic – are outcomes of binary interactions. The binary nature of short and long GRBs nevertheless differs significantly. Indeed, short GRBs are understood as binary compact object mergers while long GRBs are viewed as the products of the interactions of a neutron star and an evolved stellar core undergoing a supernova explosion. Specifically, we report on the following results:


The introduction of the Induced Gravitational Collapse paradigm leads to the idea of binary GRB progenitors. This paradigm applies to energetic long GRBs associated to supernovae, and stems from the identification of physically different episodes in the γ-ray observations of several GRBs. The sequence of events in an IGC event (also referred to as a binary-driven hypernova) is detailed, and we characterize each of the four episodes that we identify. In the IGC framework, the first episode is due to the onset of a supernova and to the accretion of the ejecta onto a companion neutron star. The second episode is produced by the collapse of this neutron star to a black hole. The third episode, which encompasses emission from the SN ejecta, the SN shock breakout, and the new neutron star remnant of the supernova, appears to follow a regular behavior: the lightcurves of the late X-ray emission show evidence for overlapping and nesting features. Finally, the fourth episode consists of the supernova peak optical signal. We also report on a work that aims at characterizing IGC events through an analysis of their joint X-ray and optical spectral energy distributions.
These initial results are expanded to several remarkable GRBs to which we apply the IGC paradigm. Thus the cases of GRB 130427A – a very energetic yet relatively nearby event –, of GRB 090423 – the farthest GRB with a spectroscopic redshift to date –, and of GRB 970828 are summarized.
In addition to the study of the long GRB population, the understanding of short GRBs is improved through the analysis of energetic short events. The prototypical GRB 090227B serves as a model for the cases of GRB 140619B and GRB 090510, which are understood as binary neutron star mergers leading to the formation of black holes. In particular, GRB 090510 bears remarkable peculiarities that we interpret in the framework of the fireshell model; these peculiarities lead us to conclude that the newborn black hole may be endowed with a high spin. An important feature of the fireshell model is its energy source: originally, electromagnetic energy extraction from a Kerr-Newman black hole was considered and found to be able to deliver up to 1055 erg in a few seconds for a 10 solar mass black hole. Thus, whether gravitational collapse to a black hole occurs or not is of paramount importance regarding the energetics of a GRB. As a consequence of this dichotomy, both short and long GRBs are further divided in two families characterized by the formation – or lack thereof – of a black hole during the course of a GRB. The classification scheme of GRBs that we obtain may be summarized by the figure.

Eckhard Strobel, "Critical and overcritical electromagnetic fields", 2016年1月 13日在罗马智慧大学答辩
Commission members: Fabio Sciarrino (Sapienza University), Ralf Schützhold (Universität Duisburg-Essen), Holger Gies (Friedrich-Schiller-Universität Jena)

We semiclassically investigate Schwinger pair production for two component electric fields depending on time.
To do so we solve the Dirac equation for two-component fields using a scattering ansatz inspired a Wentzel–Kramers–Brillouin approximation. Studying the same fields using the world-line instanton approach we find that the methods agree.
In general the results show that for two-component fields the spin distribution of produced pairs is generally not 1:1.
As a result the pair creation rates of spinor and scalar QED are different even for one pair of turning points. For rotating electric fields, the pair creation rate is dominated by particles with a specificspin depending on the sense of rotation for a certain range of pulse lengths and frequencies. We present an analytical solution for the momentum spectrum of the constant rotating field.


Figure 1. Total particle number per Compton volume of the rotating Sauter pulse for different pulse parameters. The dotted lines show the results of the DHW method. We find that the results agree in an intermediate range of the pulse length τ depending on the number of rotations σ. For small τ the semiclassical approximation breaks down, whereas for long pulses the DHW method is limited by errors in the numerical integration.

We also present a comparison to a method based upon the real-time Dirac--Heisenberg--Wigner (DHW) formalism for pulsed rotating electric fields. For the semiclassical method we propose to either perform numerical calculations or an additional approximation based on an analytical solution for the constant rotating field. We find that both numerical methods are complementary with respect tocomputation time as well as accuracy. The approximate method shows the same qualitative features while being computationally much faster.
In addition we study the fermionic Schwinger effect in two-dimensional de Sitter spacetime. For the constant electric field solutions for the Dirac equation can be found and the number of pairs can be computed using the standard Bogoliubov method. The solutions are used to compute the expectation value of the induced current. Comparing these results to similar studies for bosons, we find that while the results agree in the semiclassical limit, they do not generally agree. In particular, there is no occurrence of a strong current for small electric fields.
Furthermore, we generalize the result that for vanishing electric or magnetic fields the strong-field behavior of the one-loop Euler-Heisenberg effective Lagrangian of quantum electro dynamics is logarithmic for different limits of the Lorentz invariants. The logarithmic dependence can be interpreted as a lowest-order manifestation of an anomalous power behavior of the effective Lagrangian of QED, with critical exponents δ=e2/(12π) for spinor QED, and δS=δ/4 for scalar QED.
