This article reviews observations and models of the diffuse ionized gas that permeates the disk and halo of our Galaxy and others. It was inspired by a series...

The distribution of warm molecular gas (1000-3000 K), traced by the near-IR H2 2.12 μm line, has been imaged with a resolution

The SuperWASP cameras are wide-field imaging systems at the Observatorio del Roque de los Muchachos on the island of La Palma in the Canary Islands, and at the...

Context: Recent results suggest that there is a group of trans-Neptunian objects (TNOs) (2003 EL{61} being the biggest member), with surfaces composed of almost...

This paper describes the wave-front correction system developed for the Sunrise balloon telescope, and it provides information about its in-flight performance...

We present a new (2+1)D galaxy cluster finder based on photometric redshifts called Wavelet Z Photometric (WaZP) applied to DES first year (Y1A1) data. The...

V582 Aur is a pre-main-sequence FU Orionis type eruptive star, which entered a brightness minimum in 2016 March due to changes in the line-of-sight extinction...

We present the architecture, implementation, and on-sky validation of the fully automated acquisition and guiding system (AG) developed for the WEAVE instrument...

Current-day multi-object spectroscopic surveys are often limited in their ability to observe bright stars due to their low surface densities, resulting in...
