The Biggest Splash
In the Milky Way there exists a significant population of old and metal-rich stars on highly eccentric orbits, most likely born in-situ. It is not 100% clear how this in-situ halo population came abou...

From halo to intergalactic medium: directly constraining the properties of large-scale gas around high-redshift quasars
At high redshift most of the baryons reside outside galaxies, in an intricated network of sheets, filaments and knots, also known as the Cosmic Web. The direct detection of this large-scale gas struct...
