The Moon's changeable aspect during a lunar eclipse is largely attributable to variations in the refracted unscattered sunlight absorbed by the terrestrial atmosphere that occur as the satellite crosses the Earth's shadow. The contribution to the Moon's aspect from sunlight scattered at the Earth's terminator is generally deemed minor. However, our

We present the IACOB spectroscopic database, the largest homogeneous database of high-resolution, high signal-to-noise ratio spectra of Northern Galactic OB-type stars compiled up to date. The spectra were obtained with the FIES spectrograph attached to the Nordic Optical Telescope. We briefly summarize the main characeristics and present status of

Using deep, high-spatial-resolution imaging from the Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) Coma Cluster Treasury Survey, we determine colour profiles of early-type galaxies in the Coma cluster. From 176 galaxies brighter than MF814W(AB)=-15 mag that are either spectroscopically confirmed members of Coma or identified by eye

We report recent results from the photometric follow-up study we are conducting in the context of the SAURON project. We use ground-based MDM V -band and Spitzer/IRAC 3.6 μm imaging to characterise our sample of E, S0 and Sa galaxies photometrically. Combined with SAURON integral-field spectroscopic observations, this information allows us to

We present spectroscopic observations of the type 2 quasar SDSS J11311.05+162739.5 (z= 0.1732), which has the richest spectrum of forbidden high-ionization lines (FHILs, e.g. [Fe VII], [Fe X], [Fe XI] and [Ne V]) yet reported for an active galactic nucleus (AGN), as well as unusually strong [O III] λ4363 emission. The study of this object provides
