Physics of neutron stars: numerical simulations and multi-messenger signals Abstract Neutron stars are born in core-collapse supernova events with the collapse of the iron core of massive main-sequence stars, leading to an explosion of the outer layers. This produces a hot proto-neutron...
A small practical tutorial for cosmological N-body simulations Abstract Clément Stahl will give a small tutorial on generating cosmological initial conditions and running a simple N-body simulation of structure formation. This tutorial will first feature a theoretical overview of the field...
Dust and metals in galaxies at Cosmic Noon Abstract At the peak epoch of cosmic star formation activity, z ∼ 2, the obscured star-formation rate (SFR) density of our Universe traced by infrared light is ∼ 4 to 8 times higher than the unobscured SFR density traced by the UV luminosity....
(M)HD turbulence synthesis for astrophysics Abstract An analytical model for 3D incompressible turbulence was recently introduced in the hydrodynamics community which, with only a few parameters, shares many properties of experimental and numerical turbulence. In our work, we extend this...
On the Edge: the relation between stellar and dark matter halos of Milky Way-mass galaxies Abstract I will discuss the predictions of the Cold Dark Mater model on the build-up of stellar and dark matter halos of Milky Way-mass galaxies. I will show that the stellar and dark matter halos...
Morphology and dynamics of globular clusters Abstract Globular clusters have long been considered to be spherically symmetric, isotropic, non-rotating stellar systems. However, this simple picture has been revolutionized by a series of recent discoveries about their kinematic and structural...
Internal shocks as a candidate for Prompt Gamma Ray Bursts (GRB)s Abstract Internal shocks are one of the prominent dissipation mechanisms for prompt gamma-ray emission. In internal shocks, each collision between two shells forms a pair of forward and reverse shocks, which dissipate part of...
The Strasbourg Astronomical Observatory is delighted to be hosting the 2023 edition of the annual days of the Société Française d'Astronomie et d'Astrophysique (SF2A), from 20 to 23 June on the Esplanade campus. More than 500 people have registered for this highlight of French...
Sun Unleashed: two approaches to predicting solar eruptions Abstract The spectacular phenomena known as solar eruptions can impact human infrastructure. As our society becomes more and more sensitive to solar activity due to the technological evolution, solar forecasting is a growing...
Extreme variability in active galactic nuclei: detection with eROSITA and results from multi-wavelength follow-up Abstract Active galactic nuclei (AGN) are known to be variable at all wavelengths and on many timescales. Large optical surveys have revealed a small number of AGN that show...
