Researchers at the Instituto de Astrofísica de Canarias produce a new method to make a precise analysis of the speed of the density waves which propagate in spiral galxies

Santa Cruz de La Palma will host a debate on the results obtained by this high-energy instrumentin recent years and will add a fourth star in the Science Stars Walk (Paseo de las Estrellas de la Ciencia) in honour of Physics Nobel Laureate Samuel Ting.

This FECYT-funded project of the Instituto de Astrofísica de Canarias (IAC) has produced the largest panoramic view of our galaxy without using professional telescopes.

An international team, including researchers from the Instituto de Astrofísica de Canarias (IAC) and the University of La Laguna (ULL), participated in the discovery of a star at a distance of nine billion lightyears from Earth.

This week Thomas Soifer, Gregory Fahlman, and Masanori Iye, members of the Board of Governors of the Thirty Metre Telescope (TMT) International Observatory, visited during the week the installations of the headquarters of the Instituto de Astrofísica de Canarias (IAC), in La Laguna, and the Teide and Roque de los Muchachos Observatories.

Galaxy-cluster gravitational lenses can magnify background galaxies by a total factor of up to ~50. Here we report an image of an individual star at redshift z = 1.49 (dubbed MACS J1149 Lensed Star 1) magnified by more than ×2,000. A separate image, detected briefly 0.26″ from Lensed Star 1, is probably a counterimage of the first star demagnified for multiple years by an object of ≳3 solar masses in the cluster. For reasonable assumptions about the lensing system, microlensing fluctuations in the stars’ light curves can yield evidence about the mass function of intracluster stars and
