We present a comparison of the spin parameter λ R, measured in a region dominated by the galaxy disc, between 20 pairs of nearby (0.005 < z < 0.03) seemingly isolated twin galaxies differing in nuclear activity. We find that 80-82% of the active galaxies show higher values of λ R than their corresponding non-active twin(s), indicating larger

The off-centered bar and its single spiral arm are the most defining morphological features of the Large Magellanic Cloud (LMC), prototype of the Magellanic Spirals. Fortunately, its proximity and the quality of the colour-magnitude diagrams from SMASH allow an unprecedented characterisation of its stellar populations covering its whole extension

Amanar aims to support and inspire the Sahrawi community from the refugee camps in Tindouf, Algeria, using Astronomy. The initiative pays special attention to Sahrawi children and youth in order to awaken their interest in science, stimulate their imagination and critical thinking and enhance their resilience. The project also promotes mutual

En el marco de la campaña #IACUniversoEnCasa generada por la COVID-19 se han difundido audiocuentos ilustrados (para niños y adultos) de divulgación científica con temática astronómica (las estrellas, el Sol, Plutón, el Big Bang y la Vía Láctea) en un canal de YouTube y en redes sociales.

The low surface brightness Universe is one of the last frontiers in observational Astronomy, even a deep large multi-band survey such as the SDSS/Stripe82 is essentially blind to the presence of small (<10 arcsec) extended sources with surface brightness fainter than 28.6 mag/arcsec 2 (Stripe82 limiting surface brightness in the r-band). At surface

The Baryon acoustic oscillations from Integrated Neutral Gas Observations (BINGO) telescope is a 40-m class radio telescope under construction that has been designed to measure the large-angular-scale intensity of Hi emission at 980-1260 MHz and hence to constrain dark energy parameters. A large focal plane array comprising of 1.7-metre diameter, 4
