  • MUSE-adaptive optics view of the starburst-AGN connection: NGC 7130

    We combine ALMA and MUSE-NFM (narrow field mode, with full four-laser adaptive optics correction) data at 0.15 arcsec spatial resolution of the archetypical AGN-starburst "composite" galaxy NGC 7130. We present the discovery of a small 0″.2 (60 pc) radius kinematically decoupled core or small bi-polar outflow, as well as a larger-scale outflow. We

  • What Equinox?

    Equinox, what a controversial concept! Since the dawn of archaeoastronomy this has arguably been the most problematic concept—perhaps together with the lunar standstills or lunistices (González García and Belmonte, Journal of Skyscape Archaeology, 5(2):178-190, 2019)—to be taken into account since it was first used in `megalithic' astronomy to

  • Characterization of the craters' surface at Ryugu using NIR spectroscopy

    Asteroid Ryugu was observed up close for almost a year and a half by the instruments on-board the Japanese Aerospace eXploration Agency (JAXA) Hayabusa2 spacecraft. It has been shown that in the near-infrared wavelength ranges, the asteroid exhibits relatively homogeneous spectral characteristics: including a very low reflectance factor, a slight

  • The plague of magnetic spots among the hot stars of globular clusters: a bridge between MS and WD stars

    I will report on our recent discovery of a wide-spread photometric variability among hot (~20,000 – 30,000 K) extreme horizontal branch (EHB) stars in Galactic globular clusters. The EHB variability is periodic, displaying single-wave, low-amplitude and ~2-50 days modulations. The variability cannot be ascribed to either binary evolution or

  • 25 years of the Spanish Meteor Network (SPMN) and the 2020 Ursid Meteor Activity

    We present a short update about the Spanish Fireball and Meteorite Recovery Network (in brief known as SPMN) after 25 years of continuous monitoring of the sky over Spain and bordering countries. A recent progress has been done in the development of a unique software called 3D-FireToc, which allows the detection and fully automatic reduction of

  • A search for transiting planets around hot subdwarfs. I. Methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS

    Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent opportunities for addressing the question of the evolution of exoplanetary systems directly after the RGB phase of evolution. Aims: In this project we aim to perform a transit survey in all
