A substantial fraction of stars can be found in wide binaries with projected separations between ∼10 ^2 and 10 ^5 au. In the standard lore of binary physics, these would evolve as effectively single stars that remotely orbit one another on stationa

With its cored surface brightness profile, the elliptical galaxy NGC 5419 appears as a typical high-mass early-type galaxy (ETG). However, the galaxy hosts two distinct nuclei in its center. We use high-signal MUSE (Multi-unit Spectroscopic Explorer

We present $N\mathrm{-body} $ simulations, including post-Newtonian dynamics, of dense clusters of low-mass stars harbouring central black holes (BHs) with initial masses of 50, 300, and 2000 $\mathrm{M_{\odot}}$. The models are evolved with the $N\m

We introduce a new model for the accretion and feedback of supermassive black hole (SMBH) binaries to the KETJU code, which enables us to resolve the evolution of SMBH binaries down to separations of tens of Schwarzschild radii in gas-rich galaxy mer

In capital intensive industries, the purchasing of IoT, predictive maintenance or other digital solutions is very complex as there already exists several separate legacy systems. Also for a single solution provider, the customer needs and expectation

We present here self-consistent zoom-in simulations of massive galaxies forming in a full cosmological setting. The simulations are run with an updated version of the KETJU code, which is able to resolve the gravitational dynamics of their supermassi

Turnaround maintenances (TAMs) are huge projects in terms of manpower and expenditure and therefore they have a direct effect to company’s profitability. TAMs include several challenges, such as prioritizing the maintenance tasks, scheduling the pr
