The density of the Milky Way's corona at through ram pressure stripping of the Draco dSph galaxy

Asger Grønnow, Filippo Fraternali, Federico Marinacci +4

Satellite galaxies within the Milky Way's (MW) virial radius are typically devoid of cold gas due to ram pressure stripping by the MW's corona. The density of th…

Clouds accreting from the IGM are not able to feed the star formation of low-redshift disc galaxies

Andrea Afruni, Gabriele Pezzulli, Filippo Fraternali +1

Galactic halos accrete material from the intergalactic medium (IGM) and part of this accretion is expected to be in the form of cool ( K) gas. A signature of this proces…

Magnetic field draping around clumpy high-velocity clouds in galactic halo

Seoyoung Lyla Jung, Asger Grønnow, Naomi McClure-Griffiths

Throughout the passage within the Galactic halo, high-velocity clouds (HVCs) sweep up ambient magnetic fields and form stretched and draped configurations of magnetic fields around…

The role of the halo magnetic field on accretion through High-Velocity Clouds

Asger Grønnow, Thor Tepper-García, Joss Bland-Hawthorn +1

High-Velocity Clouds (HVCs) are believed to be an important source of gas accretion for star formation in the Milky Way. Earlier numerical studies have found that the Galactic magn…

Efficiency of Thermal Conduction in a Magnetised Circumgalactic Medium

Richard Kooij, Asger Grønnow, Filippo Fraternali

The large temperature difference between cold gas clouds around galaxies and the hot halos that they are moving through suggests that thermal conduction could play an important rol…

Magnetic fields in the Galactic halo restrict fountain-driven recycling and accretion

Asger Grønnow, Thor Tepper-García, Joss Bland-Hawthorn

The Galactic halo contains a complex ecosystem of multiphase intermediate-velocity and high-velocity gas clouds whose origin has defied clear explanation. They are generally believ…

Magnetized High Velocity Clouds in the Galactic Halo: A New Distance Constraint

Asger Grønnow, Thor Tepper-García, Joss Bland-Hawthorn +1

High velocity gas that does not conform to Galactic rotation is observed throughout the Galaxy's halo. One component of this gas, HI high velocity clouds (HVCs), have attracted att…

Merging galaxies produce outliers from the Fundamental Metallicity Relation

Asger Grønnow, Kristian Finlator, Lise Christensen

From a large sample of local SDSS galaxies, we find that the Fundamental Metallicity Relation (FMR) has an overabundance of outliers, compared to what would be ex…
