STScI/JHU Low Density Universe

The STScI/JHU Low Density Universe "supergroup" is a collection of STScI and JHU science research groups and researchers that share an interest in the baryonic Universe at low density, from the circumstellar medium to the interstellar medium to the intergalactic medium. We meet biweekly to discuss science and host visitors.
