Star-FormationRatesofGalaxies
Star-formation is one of the key processes that shape the current state and evolution of galaxies.
This volume provides a comprehensive presentation of the different methods used to measure the
intensity of recent or ongoing star-forming activity in galaxies, discussing their advantages and
complications in detail. It includes a thorough overview of the theoretical underpinnings of star-
formation rate indicators, including topics such as stellar evolution and stellar spectra, the stellar
initial mass function, and the physical conditions in the interstellar medium. The authors bring
together in one place detailed and comparative discussions of traditional and new star-formation
rate indicators, star-formation rate measurements in different spatial scales, and comparisons of
star-formation rate indicators probing different stellar populations, along with the corresponding
theoreticalbackground.Thisisausefulreferenceforstudentsandresearchersworkinginthefieldof
