Guest Editors: Klaus Blaum, Maria Jose Garcia Borge
The progress made in recent years on the precision frontier in the determination and prediction of ground and excited state nuclear properties has been amazing. The advances in technology mainly concerning ion traps, storage rings, lasers, high-precision frequency measurements, detectors, and particle beams as well as advances in atom and ion manipulation have allowed for major breakthroughs in the determination of fundamental parameters and quantities of radionuclides such as masses, electromagnetic moments, lifetimes and beta decay correlations. In a similar manner, significant progress has been made in the theoretical description of the nucleus and its properties.

The Advanced GAmma Tracking Array (AGATA) is a major European project, involving over 40 institutes in 12 countries, to develop and operate a high-resolution gamma-ray tracking spectrometer. Gamma-ray tracking requires the accurate determination of the energy, time and position of every interaction as a gamma ray deposits its energy within the detector volume. This is achieved by using electrically segmented hyper pure germanium detectors, pulse shape analysis of the digitised signals, and tracking algorithms to reconstruct the full event. The AGATA 4π geometry comprises 180 tapered-hexagonal coaxial detectors. AGATA can measure gamma rays from 10’s of keV to 10 MeV with excellent efficiency and position resolution and has a very high count rate capability. These features result in an instrument with a resolving power of two orders of magnitude larger than previous spectrometers, such as EUROBALL in Europe and Gammasphere in the USA. A similar tracking spectrometer is being constructed in the USA, called GRETA.
EPJ A Highlight - An overview of the management structure of the AGATA collaboration

The AGATA project could eventually lead to a deeper understanding of the strong nuclear force. This paper details the project’s highly sophisticated management structure, which will be essential to achieving this goal.
The Advanced Gamma Tracking Array (AGATA) is a European gamma-ray spectrometer that is already achieving unparalleled levels of sensitivity in nuclear gamma-ray spectroscopy. Ensuring success in the project’s construction and operation has involved developing a highly sophisticated structure of management and organisation. This contribution to the EPJ A topical collection “AGATA: Advancements in Science and Technology” describes the roles and responsibilities of each of AGATA’s management committees, and details the project’s scientific organisation. As AGATA promises to make major breakthroughs in our understanding of the strong nuclear force and nuclear structure in the coming decades, the paper offers a new degree of transparency for the many research groups which stand to benefit from its future discoveries.

EPJ A Topical Collection: Light Clusters in Nuclei and Nuclear Matter: Nuclear Structure and Decay, Heavy Ion Collisions, and Astrophysics

Clustering in nuclei and nuclear matter is an interesting aspect which was intensely worked out during the last two decades. It concerns not only exotic nuclei such as Hoyle-like states, but leads to a better description of general aspects of nuclear structure and reactions. In particular, clustering is essential to understand fission and alpha decay, as well as heavy ion collisions from low to highest energies. In astrophysics, the thermodynamic properties of stellar matter below saturation density, transport properties, and the evolution of compact stellar objects are determined by clustering of nuclear matter. Contributions of this emerging field are collected in this Topical Collection.

In recent years, the impact of strong magnetic fields on the strongly interacting matter phase diagram has been a very active field of research with important developments. The presence of these strong magnetic fields modifies the dynamics of quarks, gluons and hadrons and is expected to have an enormous influence over all regions of the phase diagram: from the first stages of the Universe to the physics of neutron stars and the quark gluon plasma.

The publishers of The European Physical Journal A: Hadrons and Nuclei are pleased to announce the appointment of Dr Patrizia Rossi as Managing Editor for Reviews and Letters to the Editor (experiment) as of 1 January 2022.
Patrizia Rossi is the Deputy Associate Director for Nuclear Physics at Jefferson Lab (JLab), Research Professor at George Washington University, and Research Director at the Frascati National Laboratories of INFN-Italy (on leave). Her scientific research focuses on hadron and nuclear physics using electromagnetic probes. This research aims to study the structure of the nucleon and the nature of the strong interaction in terms of fundamental constituents of QCD. Her most recent investigations are related to the study of the transverse momentum parton distribution functions for which she is co-spokesperson for several experiments.
EPJ A Highlight - Celebrating the impacts of Jacques Raynal’s work in the development of nuclear reaction formalism, codes and analysis

- Published on 08 November 2021
This topical article edition of EPJ A is dedicated to the memory of French nuclear physicist Jacques Raynal, who passed away on April 10th, 2020.
It illustrates, through a series of peer-reviewed articles, the various facets of what Raynal and his colleagues accomplished, as well as the profound influence of his results in several domains of nuclear reactions, both for theory formalism and for the analysis and understanding of experimental observables. The articles also demonstrate how his work paved the way for the future development of concepts and numerical codes for nuclear reaction calculations.

A new collection of papers focusing on the dynamics of nuclei pays fitting tribute to Iraqi/Brazilian physicist Mahir Saleh Hussein.
On 16th May 2019 Iraqi/ Brazilian physicist Mahir Saleh Hussein passed away leaving behind a distinguished career of achievements in a broad range of physics disciplines. There is, perhaps, no better way of paying tribute to this influential figure in physics than presenting a collection of cutting-edge, peer-reviewed papers. A special edition of EPJ A, edited by Valdir Guimarães, Universidade de São Paulo Instituto de Física, Brazil, Carlos Bertulani, Department of Physics of the Texas A&M University-Commerce, USA, and Nicolas Alamanos, Deputy Director of the Institute of Research into the Fundamental Laws of the Universe (IRFU), France, brings together a collection of papers focusing on nuclei clustering and dynamics as a fitting tribute to Hussein.
