New Frontiers in Gravitational Collapse and Spacetime Singularities

The book collects a series of articles to review the advances that have been made in the field of gravitational collapse in general relativity and alternative theories of gravity in the past few years. Many approaches to black hole and singularity formation in general relativity and beyond have been proposed over the last few decades. The importance of collapse models is that they provide natural thought experiments where to test the behavior and properties of a variety of approaches to general relativity and its implications for ultra-compact objects in the universe.

Prof. Daniele Malafarina is currently Associate Professor at the Department of Physics, Nazarbayev University, Kazakhstan. He has been working on relativistic gravitational collapse since his Ph.D. Over the past 15 years, he has published around 50 articles on collapse and black hole physics.

Prof. Pankaj S. Joshi is currently Distinguished Professor & Founding Director at the International Centre for Space & Cosmology, Ahmedabad University, India. Earlier he was Senior Professor at the Tata Institute of Fundamental Research, India. He has a decade-long experience on relativistic gravitational collapse. He was among the first to investigate naked singularities in Lemaitre-Tolman-Bondi collapse models and has written dozens of articles and two books on the subject: Global Aspects in Gravitation and Cosmology (OUP, 1993) and Gravitational Collapse and Spacetime Singularities (CUP, 2007).
