The NASA Transiting Exoplanet Survey Satellite (NASA-TESS) mission presents a treasure trove for understanding the stars it observes and the Milky Way, in which they reside. We present a first look at the prospects for Galactic and stellar astrophysics by performing initial asteroseismic analyses of bright (G < 11) red giant stars in the TESS

We report detection of PSR B0656+14 with the Gran Telescopio Canarias in narrow optical F657, F754, F802, and F902 and near-infrared JHK s bands. The pulsar detection in the K s band extends its spectrum to 2.2 $\mu$ m and confirms its flux increase towards the infrared. We also present a thorough analysis of the optical spectrum obtained by us

Recent developments of transition-edge sensors (TESs), based on extensive experience in ground-based experiments, have been making the sensor techniques mature enough for their application on future satellite cosmic microwave background (CMB) polarization experiments. LiteBIRD is in the most advanced phase among such future satellites, targeting

The large-scale polarization explorer (LSPE) is a cosmology program for the measurement of large-scale curl-like features (B-modes) in the polarization of the cosmic microwave background. Its goal is to constrain the background of inflationary gravity waves traveling through the universe at the time of matter-radiation decoupling. The two

Asimismo, investigamos las características fotométricas de los 351 miembros de Toro ya conocidos. En total se aplicaron 40 criterios de selección. Para confirmar la pertenencia a una de las regiones de todas las fuentes selecionadas, los candidatos se observaron mediante espectroscopia óptica de baja resolución. En estos rangos de longitud de onda

Una de las cuestiones básicas de la Astronomía moderna es cómo las galaxias de las diferentes familias han evolucionado desde su formación. Una de estas familias, las galaxias de tipos tempranos (ETGs, del inglés Early-Type Galaxy), formadas por galaxias elípticas y lenticulares y que contienen la mayor parte de la materia luminosa del Universo, ha
