Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the larger galaxy would remove the gas from it, leaving it shorn of the material it would need to make new stars. However, for the first time, a team led by the researcher at the Instituto de Astrofísica de Canarias (IAC), Arianna di Cintio, has shown using numerical simulations that this is not always the case. The results of the study were recently published in the journal Monthly Notices of the Royal Astronomical Society (MNRAS).

In 2015 and 2019 an international team (USA, Japan and Europe) carried out two unprecedented suborbital space experiments called CLASP and CLASP2, which were motivated by theoretical investigations carried out at the IAC. After the success of such missions, the team has just launched CLASP2.1 from the NASA facility in White Sands Missile Range (New Mexico, USA). The aim is to map the solar magnetic field throughout the chromosphere of an active region. To this end, CLASP2.1 has successfully measured the intensity and polarization of the solar ultraviolet radiation emitted by magnesium and

A study, led by researchers at the Instituto de Astrofísica de Canarias (IAC) and carried out with OSIRIS, an instrument on the Gran Telescopio Canarias (GTC), has found the most densely populated galaxy cluster in formation in the primitive universe. The researchers predict that this structure, which is at a distance of 12.5 billion light years from us, will have evolved becoming a cluster similar to that of Virgo, a neighbour of the Local Group of galaxies to which the Milky Way belongs. The study is published in the specialized journal Monthly Notices of the Royal Astronomical Society
