We are pleased to announce the High Resolution Spectroscopy: Towards the Extremely Large Telescopes (HRS2027) international conference to be held 19–23 April 2027 at IACTEC, San Cristóbal de La Laguna, Tenerife, Canary Islands, Spain.

High-resolution spectroscopy has been one of the fundamental tools of astrophysics for decades, enabling landmark discoveries across a wide range of fields: from the detection of exoplanets and the characterisation of stellar atmospheres, to studies of the chemical enrichment of the early Universe and tests of fundamental laws of physics. Being intrinsically a photon-starved technique, the advent of extremely large telescopes holds the promise of transformative advances, enabling new measurements and groundbreaking discoveries that are currently beyond reach.

This conference will bring together scientists using high-resolution spectroscopy to address fundamental questions across astrophysics and to discuss recent advances spanning the Solar System, exoplanets and protoplanetary discs, stars and stellar populations, galaxy formation and evolution, the circumgalactic and intergalactic medium, cosmology, and fundamental physics. The conference will also provide a forum to discuss the opportunities offered by the next generation of high-resolution spectrographs being developed for extremely large telescopes, with a key goal of exploring how observing strategies and campaigns can be optimised to fully exploit these new capabilities.
