A systematic survey of Moon-forming giant impacts: Non-rotating bodies

Miles Timpe, Christian Reinhardt, Thomas Meier +2

In the leading theory of lunar formation, known as the giant impact hypothesis, a collision between two planet-size objects resulted in a young Earth surrounded by a circumplanetar…

Modular forms, projective structures, and the four squares theorem

Michael Eastwood, Ben Moore

It is well-known that Lagrange's four-square theorem, stating that every natural number may be written as the sum of four squares, may be proved using methods from the classical th…

Estimating the dark matter velocity anisotropy to the cluster edge

Jacob Svensmark, Steen H. Hansen, Davide Martizzi +2

Dark matter dominates the properties of large cosmological structures such as galaxy clusters, and the mass profiles of the dark matter have been measured for these equilibrated st…

The fate of planetesimal discs in young open clusters: implications for 1I/'Oumuamua, the Kuiper belt, the Oort cloud and more

Thomas Oliver Hands, Walter Dehnen, Amery Gration +2

We perform -body simulations of the early phases of open cluster evolution including a large population of planetesimals, initially arranged in Kuiper-belt like discs around eac…

Infall near clusters of galaxies: comparing gas and dark matter velocity profiles

L. Albaek, S. H. Hansen, D. Martizzi +2

We consider the dynamics in and near galaxy clusters. Gas, dark matter and galaxies are presently falling into the clusters between approximately 1 and 5 virial radii. At very larg…

Close-in planetesimal formation by pile-up of drifting pebbles

Joanna Drazkowska, Yann Alibert, Ben Moore

The consistency of planet formation models suffers from the disconnection between the regime of small and large bodies. This is primarily caused by so-called growth barriers: the d…
