There is an intense debate in cultural astronomy on the importance of lunar standstills in prehistory or antiquity, and even on whether this elusive and difficult-to-understand phenomenon actually was then recognised. In the present paper, we seek to address those who advocate no longer using the terms "lunar standstill" or the related "lunistice"

Presentamos un estudio de la relación entre astronomía y paisaje centrado en la orientación de las iglesias y ermitas cristianas de la isla de La Gomera, situada en el Archipiélago Canario (España). El trabajo de campo consistió en la medición de las coordenadas precisas de ubicación de 38 iglesias y ermitas, lo que representa la casi

In earlier works, we had shown the actual possibility that the Nabataeans had used the Equinox, or an astronomical event equivalent to this, as an important milestone to control the calendar, stablish festivals and perform pilgrimages to important sacred sites. In this paper we present evidence that this was indeed the case. In a research carried

The support of the international astronomical community to the 2030 Agenda for Sustainable Development is fundamental to advance the rights and needs of the most vulnerable groups of our global society. Among these groups are the refugees.

This work presents a new design methodology for radio frequency (RF) integrated circuits based on a unified analysis of the scattering parameters of the circuit and the gm/ID ratio of the involved transistors. Since the scattering parameters of the circuits are parameterized by means of the physical characteristics of transistors, designers can

Near-infrared spectroscopic surveys have uncovered a population of short-period, blended-light spectral binaries composed of low-mass stars and brown dwarfs. These systems are amenable to orbit determination and individual mass measurements via astrometric monitoring. Here, we present first results of a multiyear campaign to obtain high-precision
