Generation of solar spicules and subsequent coronal heating
Spicules are rapidly evolving fine-scale jets of magnetized plasma in the solar chromosphere. It remains unclear how these prevalent jets originate from the solar surface and what role they play in he...

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...

The quasi-equilibrium structure of dark matter halos: from theory to observation
Dark matter halos are approximately virialized condensation of dark matter and serve as the building blocks of large scale structure and galaxy formation. These structures, however, are not fully in e...

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...
