Left panel: map of the surface brightness of "the Antennae" in emission from ionized hydrogen. The brightest zones are the zones occupied by clusters of massive stars. Right panel: map of the expansion velocity of the bubbles detected in the Antennae, pus
El reconocimiento, concedido por la Sociedad Española de Astronomía, destaca la colaboración entre personal profesional y astrónomo aficionado en un proyecto internacional para el seguimiento de tránsitos de exoplanetas con el telescopio IAC80 del Observatorio del Teide. El Instituto de Astrofísica de Canarias (IAC) ha sido reconocido con el IV Premio Javier Gorosabel de Colaboración ProAm en Astrofísica por su participación en el proyecto desarrollado por el grupo Urania de la Agrupación Astronómica de Sabadell , dedicado al seguimiento de tránsitos de exoplanetas mediante el telescopio
An international collaboration of astronomers led by the Universidad de La Laguna (ULL) and Instituto de Astrofísica de Canarias (IAC) has identified two intriguing, humongous but light planets orbit ing HD 114082. This star is only 15 million years old, this is, much younger than the Sun (4.6 billion years old) , spin s 15 times faster , has 28% more mass , and is about one thousand degrees hotter and almost four times more luminous. Its planets receive about 200 times more light and heat than Jupiter. The study, which involved separating the faint planetary signal from the stellar one
A new study published in Astronomy & Astrophysics unveils a powerful way to determine the size of dark matter haloes—the massive, invisible structures that host galaxies—by simply measuring how large galaxies appear in deep astronomical images. Researchers Ignacio Trujillo and Claudio Dalla Vecchia, from the Instituto de Astrofísica de Canarias (IAC) and the Universidad de La Laguna (ULL), demonstrate that galaxy size can serve as a precise proxy for halo size, offering measurements up to six times more accurate than previous methods. Using the cutting-edge EAGLE cosmological simulations
