In addition to clearly biological microbial mats, lava tubes contain many non-biological appearing mineral deposits that contain life. The discovery that such...

Mid-infrared observations are a vital tool for the study of a wide range of astrophysical phenomena. However, ground-based mid-infrared detectors must overcome...

JEM-EUSO is a space observatory that will be attached to the Japanese module of the International Space Station (ISS) to observe the UV photon tracks produced...

Simple gravitational lens models usually suffice to reproduce the positions of lensed quasar images, but they have problems to reproduce their optical flux...

We have considered the influence of gravitational microlensing on the spectral line profiles generated by a relativistic accretion disc model. We discuss...

Planetary nebulae (PNe) are known to possess a variety of small-scale structures that are usually in a lower ionization state than the main body of the nebulae...

We are presenting the results from observations carried out at La Palma with the Nordic Optical Telescope, focused on studying the microvariability of obscured...
