The tight correlations between supermassive black hole (SMBH) mass (M BH) and the properties of the host galaxy have useful implications for our understanding of the growth of SMBHs and of the evolution of galaxies. Here, we present newly observed correlations between M BH and the host galaxy total UV-[3.6] color ( ${{ \mathcal C }}_{\mathrm{UV}

We extend our previous work on the age-chemical abundance structure of the Galactic outer disc to the inner disc (4 < r < 8 kpc) based on the SDSS/APOGEE survey. Different from the outer disc, the inner disc stars exhibit a clear bimodal distribution in the [Mg/Fe]-[Fe/H] plane. While a number of scenarios have been proposed in the literature, it

The New Robotic Telescope (NRT) is currently under conceptual phase design, will be sited on the Observatory of Roque de los Muchachos (ORM) in La Palma (Canary Islands), and will be the largest fully robotic telescope in the world when it enters into operation in a five years time. A collecting area four times larger than the current Liverpool

This paper documents the 16th data release (DR16) from the Sloan Digital Sky Surveys (SDSS), the fourth and penultimate from the fourth phase (SDSS-IV). This is the first release of data from the Southern Hemisphere survey of the Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2); new data from APOGEE-2 North are also included

TEIDESAT is an initiative that was born in the University of La Laguna (Tenerife, Canary Islands), in December 2017, and that now involves up to 25 students, mainly from the University of La Laguna (ULL) and the University of Las Palmas de Gran Canaria (ULPGC), but that has extended widely, with students from universities in Madrid, Valencia

IGR J17091-3624 is a low-mass X-ray binary (LMXB), which received wide attention from the community thanks to its similarities with the bright black hole system GRS 1915+105. Both systems exhibit a wide range of highly structured X-ray variability during outburst, with time-scales from few seconds to tens of minutes, which make them unique in the
