ASGARD Research group

AStronomy Group for Academic Research and Dissemination

Valencian International University (VIU), Spain

The AStronomy Group for Academic Research and Dissemination (ASGARD) is composed by researchers at VIU. We work on several research lines, in the fields of galaxies, star clusters, stars, exoplanets and astronomical instrumentation, covering wavelengths from radio to X-rays (both photometry and spectroscopy). ASGARD members pursue individual projects while also collaborating on joint research endeavors, pooling resources and efforts to advance our collective scientific goals.
