Dust reprocesses the intrinsic radiation of active galactic nuclei (AGN) to emerge at longer wavelengths. The mid-infrared (MIR) luminosity depends broadly on...

CASE (Calar Alto Spectroscopic Explorer) is a new set of instruments for the Calar Alto observatory to unravelling the fine structure of galaxies in the local...

Solar magnetism may look deceptively boring (a rather common star with relatively low activity). As it turns out, even the most quiet areas of the Sun (away...

Luminous Blue Variables (LBVs) are massive stars caught in a post-main sequence phase, during which they are losing a significant amount of mass. Given the...

The Maunakea Spectroscopic Explorer (MSE, formerly Next Generation CFHT) is a project to upgrade the CFHT into a survey telescope with a 11.25-meter mirror and...

The S-class MESSIER satellite has been designed to explore the extremely low surface brightness universe at UV and optical wavelengths. The two driving science...

The current databases of empirical star spectra for modelling single-aged stellar populations (SSPs) generally do not chemically characterize their stars...

Abstract: The study of the structure of our Galaxy, particularly its inner disc, has always been hindered by two factors: interstellar extinction dims even the...

The structure, kinematics and stellar population of the Galactic bulge is very complex. Only three years ago the bulge was discovered to be X-shaped, a...
