Essentially everything of astronomical interest is either part of a galaxy, or from a galaxy, or otherwise relevant to the origin or evolution of galaxies. Diverse examples are that the isotropic composition of meteorites provides clues to the history of star formation billions of years ago, and cosmological tests for…

Nature's many varied complex systems-including galaxies, stars, planets, life, and society-are islands of order within the increasingly disordered Universe. All organized systems are subject to physical, biological, or cultural evolution, which together comprise the grander interdisciplinary subject of cosmic…

Matter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and evolution of galaxies throughout the 13-billion-year history of the…

'Punyakoti Ganeshaiah Veena'] Context. Galaxies can be classified as passive ellipticals or star-forming discs. Ellipticals dominate at the high end of the mass range, and therefore there must be a mechanism responsible for the quenching of star-forming galaxies. This could either be due to the secular processes linked…

The study of galaxy formation and evolution is one of the most active and fertile fields of modern astrophysics. It also covers a wide range of topics intimately connected with cosmology and with the evolution of the Universe as a whole. The key to decipher galaxy formation and evolution is to understand the complex…

'Benjamin D. Oppenheimer'] We use high-resolution cosmological zoom simulations with ∼ 200 pc resolution at z = 2 and various prescriptions for galactic outflows in order to explore the impact of winds on the morphological, dynamical, and structural properties of eight individual galaxies with halo masses ∼ 1011–2×1012…

'Annalisa Pillepich' 'Dylan Nelson' 'Shy Genel' 'Mark Vogelsberger' 'Lars Hernquist'] Massive quiescent galaxies have much smaller physical sizes at high redshift than today. The strong evolution of galaxy size may be caused by progenitor bias, major and minor mergers, adiabatic expansion, and/or renewed star…

We investigate the formation and evolution of the pseudobulge in "Eris", a high-resolution N-body + smoothed particle hydrodynamics (SPH) cosmological simulation that successfully reproduces a Milky Way-like massive late-type spiral in a cold dark matter (ΛCDM) universe. At the present epoch, Eris has a virial mass…

'Fumitaka Nakamura' 'Ralf Klessen' 'Javier Ballesteros-Paredes' 'Shu-ichiro Inutsuka' 'Angela Adamo' 'Patrick Hennebelle'] Giant molecular clouds (GMCs) and their stellar offspring are the building blocks of galaxies. The physical characteristics of GMCs and their evolution are tightly connected to galaxy evolution.…

'Tobias Buck' 'Gregory S. Stinson' 'Liang Wang'] We present the first results of applying Gaussian Mixture Models in the stellar kinematic space of normalized angular momentum and binding energy on NIHAO high resolution galaxies to separate the stars into multiple components. We exemplify this method using a simulated…

The Atacama Large Millimetre/submillimetre Array (ALMA) is currently in the process of transforming our view of star-forming galaxies in the distant ( $z≳1$) universe. Before ALMA, most of what we knew about dust-obscured star formation in distant galaxies was limited to the brightest submillimetre sources-the…

'J. M. Diederik Kruijssen' 'Søren S. Larsen' 'Sylvia Ploeckinger' 'Oscar Agertz' 'Michele Trenti' 'Annette M. N. Ferguson' 'Joel Pfeffer' 'Oleg Y. Gnedin'] We discuss some of the key open questions regarding the formation and evolution of globular clusters (GCs) during galaxy formation and assembly within a…

Gene duplication is a major factor contributing to evolutionary novelty, and the contraction or expansion of gene families has often been associated with morphological, physiological and environmental adaptations. The study of homologous genes helps us to understand the evolution of gene families. It plays a vital role…

New generation of sequencing platforms coupled to numerous bioinformatics tools has led to rapid technological progress in metagenomics and metatranscriptomics to investigate complex microorganism communities. Nevertheless, a combination of different bioinformatic tools remains necessary to draw conclusions out of…
