These papers showcase studies of galaxy formation, evolution, interaction, chemical abundances and stellar populations from cosmic down to the Milky Way. These proceedings offer an updated view of recent advances and current problems and is suitable for both active researchers in the field and graduate students.

This volume gives a comprehensive, up-to-date review of cosmic masers as presented at IAU Symposium 380, the sixth international maser symposium. It also describes intensive discussion about ongoing and future projects relevant to maser science, such as global and new regional VLBI networks, SKA, and ngVLA.

IAU Symposium 376 discusses recent observational and theoretical results achieved by the continued, detailed scrutiny of the PLR, including its shape, calibration and dependence on stellar parameters and chemical abundances. Intrinsic PLR widths may offer unique insights into the physical processes shaping these relations and the underlying physical properties of the stars contributing to these relationships.

A guided journey to the inner workings of Earth - and the cloaked mysteries of other planets in our solar system and beyond. We live on the surface of Earth, but rarely consider the fascinating world beneath our feet.

This new book explores the pioneering field of transient - or time-domain - astronomy, the incredible discoveries being made, the tools that we use to detect these cosmic events, and the aspects that continue to puzzle observers and theorists. In an engaging style accessible to the layperson, the astronomer and popular science author gives us an up-to-date overview of the "transient universe, " and explains how astronomers came to see the cosmos as a dynamic place, rather than a static one.

With his knowledgeable yet conversational approach, Shapiro offers an enjoyable way for the curious to learn about the foundations of a range of scientific topics: the motions of bodies in the cosmos, the history and structure of the earth, the evolution of organisms, and the search for extraterrestrial life and intelligence.

The Standard Model is an elegant and extremely successful theory that formulates the laws of fundamental interactions among elementary particles. This incisive textbook introduces students to the physics of the Standard Model while providing an essential overview of modern particle physics, with a unique emphasis on symmetry principles as the starting point for constructing models.

Blazars, the most extreme active galactic nuclei with powerful relativistic jets extending out to kiloparsecs from their central engine, are among the most intriguing and consistently bright objects in the observable Universe. Understanding how they form and shine has been a cumbersome endeavor since their discovery in the 1960s, with several fundamental questions remaining open to this day.

Multi-messenger science has a long history in solar astronomy, as direct measures of "in-situ" particles emanating from the Sun, like the solar wind, have long been used alongside remote observations to shape our understanding of the heliosphere. Still, the recent advent of several major observational facilities, such as Parker Solar Probe, Solar Orbiter, and the Inouye Solar Telescope, among many others, is now heralding an exciting new era of scientific opportunities within multi-messenger solar physics.
