Present-day massive galaxies are composed mostly of early-type objects. It is unknown whether this was also the case at higher redshifts. In a hierarchical...

We describe the construction and study of an objectively defined sample of early-type galaxies in low-density environments. The sample galaxies are selected...

Tidal debris around galaxies can yield important clues on their evolution. We have identified tidal debris in 11 early-type galaxies (T

The reflectance of the Earth is a fundamental climate parameter that we measured from Big Bear Solar Observatory between 1998 and 2017 by observing the...

The Earth's albedo is a fundamental climate parameter for understanding the radiation budget of the atmosphere. It has been traditionally measured not only from...

Of the 342 planets so far discovered orbiting other stars, 58 `transit' the stellar disk, meaning that they can be detected through a periodic decrease in the...

Observations of the Earth as a planet using the earthshine technique (i.e. looking at the light reflected from the dark side of the Moon) have been used for...

The pilgrimage along the Way of Saint James constituted the principal mechanism for the introduction of new currents of thought into the Iberian Peninsula, such...

We report a methodology to determine the quality factor ( Q) of wavy dark matter detectors equipped with multilayered resonators, including Fabry-Pérot...
