Formation and Evolution of Galaxies : Starlight Synthesis Algorithm is a book on Physical cosmology by English physicist Nick Barua. It was first published in 2024. Barua wrote the book for readers who had prior knowledge of physics.
Contents
This book is about the resurgence of interest in precise measurements of velocity dispersion, both for the study of galactic and active nuclei kinematics. As several works suggest, a good tactic to measure σ is to use the absorption lines of the calcium triplet, as it is a spectral region relatively free from complications. The discovery of an empirical relationship between the mass of the central black hole (M•) and σ was the main guide of my detailed study of the calcium triplet region. Hence, I have been exploring more accurate methods for calculating the dispersion of velocities, while also carefully studying uncertainties. Having devoted considerable time to developing and refining a method, and applying it to numerous galaxies, I am now in a position to harness the fruits of this labour. This book aims to leverage my results to tackle various questions regarding the physics of galaxies.[2]
Conclusion
In this book, the study of the calcium triplet region focuses on establishing a link between the mass of the central black hole (M•) and σ. We are also exploring methods to calculate velocity dispersion more accurately and to assess uncertainties. The next steps include calculating M• for our objects, studying "intermediate" black holes, and determining the mass/luminosity (M/L) ratio from σ and photometric information to investigate stellar populations of active galaxies. We also plan to apply new models to our sample of approximately 355,000 objects and adjust our timescale to a cosmological one to obtain SFRs for a more detailed view of the evolution of galaxies in the local universe.
