Novae play a key role in the chemical evolution of galaxies, yet important uncertainties remain regarding their occurrence rates, ejected masses, distances, and associated stellar populations. This thesis aims to investigate nova properties and evolution through spectroscopic observations, including SOXS data, and photometric survey datasets. The study will combine detailed analyses of individual events with population-level investigations in the Milky Way and nearby galaxies, including the Large and Small Magellanic Clouds. The upcoming Vera C. Rubin Observatory will enable systematic nova searches and population studies in external galaxies, providing new constraints on their demographics and contribution to galactic chemical enrichment. The thesis will also explore the connection between nova progenitor systems and compact binaries detectable through gravitational waves, assessing their potential relevance as sources for the Laser Interferometer Space Antenna (LISA).
