  • Poster of Hispanoamerican Festival of Authors in La Palma.
    The encounter, which will take place between September 18th and 22nd, in the municipality in La Palma of Los Llanos de Aridane, will bring together around forty literary figures writing in Spanish from both sides of the Atlantic. Among the planned acts the Instituto de Astrofísica de Canarias (IAC) will participate in a panel discussion which will pay tribute to the memory of Stephen Hawking, and will organize a special visit for the guests to the Roque de los Muchachos Observatory.

  • Poster workshop BUKS2018. Credit: IAC.
    Tomorrow, in La Laguna, sees the start of the BUKS2018 conference, which will bring together for a week 77 specialists in Solar Physics from 14 countries to discuss the latest research on the waves and instabilities which are produced in the atmosphere of the star in our neighbourhood.

  • M87 image taken with WFC3 from HST (2016) with the F814W filter. Different knots can be seen along the jet, including the first HST-1 knot. Credit: ESA
    The study, carried out by two researchers at the Instituto de Astrofísica de Canarias, shows that the “change in position” observed in the nucleus of the galaxy M87 is not due to a displacement of its supermassive black hole, but to variations in the emission of light in the centre of the galaxy caused by outbursts coming from its jet, a flow of relativistic material along a narrow beam, emitted from just outside the black hole itself.

  • Spectral energy distribution for the nucleus of NGC 1052. Different symbols represent the sub-arcsec and low-angular resolution measurements, interpolation, power-law, hot standard disc, and a Seyfert 2 template.
    Low-luminosity active galactic nuclei (LLAGNs) are found in about 1/3 of all the galaxies in the Local Universe, establishing the most numerous class of AGNs. At low accretion rates, LLAGNs are expected to develop major changes in the structure of the accretion disc when compared to their bright counterparts, Seyfert galaxies and Quasars. Here we present high-angular resolution data (~13 pc) for the LLAGN in the nucleus of NGC 1052, covering 10 orders of magnitude in frequency from radio to X-rays. The flux distribution of the nucleus is well described by a broken power law plus an inverse
