Paper Abstract

The Observatorio del Roque de Los Muchachos (ORM) on the Canary island of La Palma has been selected as the alternate site for the Thirty Meter Telescope (TMT). Several potential locations on the summit needed to be investigated in terms of Ground Layer (GL) strength. Moreover, the presence of existing observatories necessitated a study of the interaction between these observatories and TMT. Lack of localized site testing and the nature of the terrain led to the use of Computational Fluid Dynamics (CFD) simulations combined with a seeing model for GL optical turbulence estimates. Three candidate locations for TMT at ORM were investigated under certain wind directions using steady-state simulations. For the most likely candidate the influence of TMT on two nearby telescopes, Gran Telescopio Canarias (GTC) and Telescopio Nationale Galileo (TNG), and vice-versa was also explored and conclusions were drawn.
