AMICO-COSMOS galaxy cluster and group catalogue up to : Sample properties and X-ray counterparts

Greta Toni, Matteo Maturi, Alexis Finoguenov +2

We present a new galaxy cluster search in the COSMOS field through the use of the Adaptive Matched Identifier of Clustered Objects (AMICO). We produced a new cluster and group cata…

Heavy quark momentum diffusion coefficient during hydrodynamization via effective kinetic theory

Kirill Boguslavski, Aleksi Kurkela, Tuomas Lappi +2

In these proceedings, we compute the heavy quark momentum diffusion coefficient using QCD effective kinetic theory for a plasma going through the bottom-up thermalization scenario…

Limiting attractors in heavy-ion collisions

Kirill Boguslavski, Aleksi Kurkela, Tuomas Lappi +2

We study universal features of the hydrodynamization process in heavy-ion collisions using QCD kinetic theory simulations for a wide range of couplings. We introduce the new concep…

Galaxy cluster optical mass proxies from probabilistic memberships

Lia Doubrawa, Eduardo S. Cypriano, Alexis Finoguenov +4

Robust galaxy cluster mass estimates are fundamental for constraining cosmological parameters from counts. For this reason, it is essential to search for tracers that, independent…

Tidal disruption of near-Earth asteroids during close encounters with terrestrial planets

Mikael Granvik, Kevin J. Walsh

Numerical modeling has long suggested that gravitationally-bound (or so-called rubble-pile) near-Earth asteroids (NEAs) can be destroyed by tidal forces during close and slow encou…

Photospheric Lorentz force changes in eruptive and confined solar flares

Samriddhi Sankar Maity, Ranadeep Sarkar, Piyali Chatterjee +1

Solar flares are known to leave imprints on the magnetic field at the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in loca…
