    The CCI supports the option for the TMT to be installed at the Roque de los Muchachos Observatory
    Statement supporting the selection of La Palma for the Thirty Meter Telescope (TMT) site: The Comité Científico Internacional (CCI) of the Canary Islands Observatories enthusiastically welcomes the possibility that the Thirty Meter Telescope (TMT) may ultimately choose the Observatorio del Roque de los Muchachos (ORM) on La Palma as its site. The ORM offers outstanding astronomical conditions, decades of successful international cooperation in operating telescopes, and a robust legal framework protecting its dark skies. At its meeting on 27 November 2025 on the island of La Palma, the CCI

    Press release
    The Comité Científico Internacional of the Canary Islands Observatories holds its annual meeting in La Palma
    The members of the Comité Científico Internacional (CCI) of the Canary Islands Observatories met today on the island of La Palma. The ISC is the body established in the International Agreements that gave rise to the Canary Islands Observatories managed by the Instituto de Astrofísica de Canarias (IAC) and guarantees the effective participation of the User Institutions in decision-making regarding their use, maintenance and improvement. The meeting, held at the Hotel H10 Taburiente Playa, began with a minute's silence in memory of Professor Francisco Sánchez, founder of the IAC, whose legacy

    GalIMF–E-MILES library: Impact of an environment-dependent initial mass function on stellar population spectra
    We present, for the first time, model spectra of single-age, single-metallicity stellar populations computed with the E-MILES evolutionary synthesis code incorporating an environment-dependent, variable galaxy-wide initial mass function (gwIMF). This gwIMF, calculated using the GalIMF code, is rooted in the integrated galactic initial mass function (IGIMF) theory, which predicts IMF variations as a function of the star formation rate and the metallicity. By coupling these two codes, we generated a comprehensive library of single-burst stellar population spectra uniquely sensitive to gwIMF
