An international team of scientists led from the Centre for Astrobiology (CAB, CSIC-INTA), with participation from the Instituto de Astrofísica de Canarias (IAC), has used the Gran Telescopio Canarias (GTC) to study a representative sample of galaxies, both disc and spheroidal, in a deep sky zone in the constellation of the Great Bear to characterize the properties of the stellar populations of galactic bulges. The researchers have been able to determine the mode of formation and development of these galactic structures. The results of this study were recently published in The Astrophysical

The detection of the axion would mark a key episode in the history of science. This hypothetical particle could resolve two fundamental problems of Modern Physics at the same time: the problema of Charge and Parity in the strong interaction, and the mystery of dark matter. However, in spite of the high scientific interest in finding it, the search at high radio frequency -above 6 GHz- has been almost left aside for the lack of the high sensitivity technology which could be built at reasonable cost. Until now.

In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses. In this context, a team of researchers led by Borja Toledo Padrón, a Severo Ochoa-La Caixa doctoral student at the Instituto de Astrofísica de Canarias (IAC), specializing in the search for planets around this type of stars, has discovered a super-Earth orbiting the star GJ 740, a red dwarf star situated some 36 light years

We present COSMIC BIRTH (COSMological Initial Conditions from Bayesian Inference Reconstructions with THeoretical models): an algorithm to reconstruct the primordial and evolved cosmic density fields from galaxy surveys on the light-cone. The displacement and peculiar velocity fields are obtained from forward modelling at different redshift snapshots given some initial cosmic density field within a Gibbs-sampling scheme. This allows us to map galaxies, observed in a light-cone, to a single high redshift and hereby provide tracers and the corresponding survey completeness in Lagrangian space

El Instituto de Astrofísica de Canarias (IAC) y el Centre National de la Recherche Scientifique (CNRS), el mayor organismo público de investigación de Francia, firmaron ayer, reunidos por videoconferencia y en el marco de las actividades de la XXVI Cumbre Hispano-Francesa, un acuerdo por el que se establece la creación del primer laboratorio internacional del CNRS en territorio español. Firmaron el convenio el Dr. Guy Perrin, director del I nstitut National des Sciences de l'Univers ( INSU ) del CNRS, y el Prof. Rafael Rebolo, director del IAC, en presencia de otros miembros directivos y

“Las mujeres sostienen la mitad del cielo”, dice un proverbio chino y máxima muy presente en el Instituto de Astrofísica de Canarias (IAC), que un año más se suma a la celebración del 8 de Marzo, Día Internacional de la Mujer. Y lo hace con una serie de actividades que, entre otros fines, buscan reivindicar el papel de las mujeres de distintos perfiles y ámbitos -investigación, enseñanza, instrumentación, divulgación, servicios informáticos, instalaciones telescópicas y administración- que trabajan en este centro.
