Stars and Planets in the Ultraviolet: A Cross-Community Symposium

An Interactive Workshop to Explore Novel Ideas for Future Scientific, Educational, and Cultural Activities with the Arecibo Observatory

This program is motivated by the recent observational insights concerning white dwarfs as individuals and as a population, based on the astrometry from Gaia and large photometric (e.g. Kepler,TESS, ZTF) and spectroscopic...

Gas in the halos of galaxies dominates the universe's baryon budget, traces its dark-matter potential wells, and supplies the fuel for star formation. Circumgalactic gas has also long been suspected to regulate galaxy...

The circumgalactic medium (CGM) can be viewed as an atmosphere that surrounds a galaxy and sustains star formation within it. Much of what we know about the CGM has come from absorption-line spectroscopy, mainly in the...
