Gaia DR2 unravels incompleteness of nearby cluster population: New open clusters in the direction of Perseus

T. Cantat-Gaudin, A. Krone-Martins, N. Sedaghat +13

Open clusters (OCs) are popular tracers of the structure and evolutionary history of the Galactic disk. The OC population is often considered to be complete within 1.8 kpc of the S…

Magnetic field tomography in two clouds towards Ursa Major using HI fibers

Aris Tritsis, Christoph Federrath, Vasiliki Pavlidou

The atomic interstellar medium (ISM) is observed to be full of linear structures that are referred to as "fibers". Fibers exhibit similar properties to linear structures found in m…
