Book Synopsis Galaxies by : Steff Jaywan
Download or read book Galaxies written by Steff Jaywan. This book was released on . Available in PDF, EPUB and Kindle. Book excerpt: Galaxies are dynamic entities, constantly evolving through processes like mergers, collisions, and interactions with neighboring galaxies. When galaxies merge, their stars, gas, and dust can undergo dramatic transformations, leading to the formation of new stars and restructuring of the galaxy's shape. These interactions can trigger intense bursts of star formation and feed supermassive black holes at the galaxies' centers, leading to the emission of powerful jets of radiation. Furthermore, galaxies are not isolated entities but are interconnected within the vast cosmic web of the universe. They cluster together in groups and clusters, bound by their mutual gravitational attraction. These clusters can contain hundreds or even thousands of galaxies, each influencing the others' evolution through gravitational interactions and tidal forces. The study of galaxies encompasses various fields of astrophysics, including observational astronomy, theoretical modeling, and simulations. Observational techniques, such as telescopes operating across different wavelengths of light and gravitational wave detectors, allow astronomers to peer into the depths of galaxies across cosmic time.

Book Synopsis Galaxy Formation and Mergers with Stars and Massive Black Holes by : Chi-hun Kim
Download or read book Galaxy Formation and Mergers with Stars and Massive Black Holes written by Chi-hun Kim. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: While mounting observational evidence suggests the coevolution of galaxies and their embedded massive black holes (MBHs), a comprehensive astrophysical understanding which incorporates both galaxies and MBHs has been missing. To tackle the nonlinear processes of galaxy formation, we develop a state-of-the-art numerical framework which self-consistently models the interplay between galactic components: dark matter, gas, stars, and MBHs. Utilizing this physically motivated tool, we present an investigation of a massive star-forming galaxy hosting a slowly growing MBH in a cosmological LCDM simulation. The MBH feedback heats the surrounding gas and locally suppresses star formation in the galactic inner core. In simulations of merging galaxies, the high-resolution adaptive mesh allows us to observe widespread starbursts via shock-induced star formation, and the interplay between the galaxies and their embedding medium. Fast growing MBHs in merging galaxies drive more frequent and powerful jets creating sizable bubbles at the galactic centers. We conclude that the interaction between the interstellar gas, stars and MBHs is critical in understanding the star formation history, black hole accretion history, and cosmological evolution of galaxies. Expanding upon our extensive experience in galactic simulations, we are well poised to apply this tool to other challenging, yet highly rewarding tasks in contemporary astrophysics, such as high-redshift quasar formation.

Book Synopsis Dust in Galaxies by : David A Williams
Download or read book Dust in Galaxies written by David A Williams. This book was released on 2019-12-12. Available in PDF, EPUB and Kindle. Book excerpt: Without interstellar dust, the Universe as we see it today would not exist. Yet at first we considered this vital ingredient merely an irritating fog that prevented a clear view of the stars and nebulae in the Milky Way and other galaxies. We now know that interstellar dust has essential roles in the physics and chemistry of the formation of stars and planetary systems, the creation of the building blocks of life, and in the movement of those molecules to new planets. This is the story in this book. After introducing the materials this interstellar dust is made of, the authors explain the range of sizes and shapes of the dust grains in the Milky Way galaxy and the life cycle of dust, starting from the origins of dust grains in stellar explosions through to their turbulent destruction. Later on we see the variety of processes in interstellar space involving dust and the events there that cause the dust to change in ways that astronomers and astrobiologists can use to indirectly observe those events. This book is written for a general audience, concentrating on ideas rather than detailed mathematics and chemical formulae, and is the first time interstellar dust has been discussed at an accessible level.
