Inferring the mass and size of 3I/ATLAS from its non-gravitational acceleration
Valentin Thoss, Abraham Loeb, Andreas Burkert
Observations of the interstellar object 3I/ATLAS have revealed a strong production of gas and dust near perihelion, together with rapid brightening. The outgassing from the nucleus…
SISSI: Supernovae in a stratified, shearing interstellar medium. II. Star formation near the Sun is quenched by expansion of the Local Bubble
Leonard E. C. Romano, Andreas Burkert
The age of the Local Bubble (LB) constrains the timescale on which the interstellar medium in the solar neighborhood evolves. Previous estimates placed the age of the LB at \sim 14…
SISSI: Supernovae in a stratified, shearing interstellar medium -- I. The geometry of supernova remnants
Leonard E. C. Romano, Manuel Behrendt, Andreas Burkert
Aims. We introduce the SISSI (Supernovae In a Stratified, Shearing Interstellar medium) simulation suite, which aims to enable a more comprehensive understanding of supernova remna…
Primordial Black Holes in the Solar System
Valentin Thoss, Andreas Burkert
If primordial black holes (PBHs) of asteroidal mass make up the entire dark matter, they could be detectable through their gravitational influence in the solar system. In this work…
The Turbulent Support (TS) and Global Hierarchical Collapse (GHC) models for molecular clouds compared. Differences, convergence, and myths
Enrique Vázquez-Semadeni, Aina Palau, Gilberto C. Gómez +8
We provide a detailed comparison between the ``turbulent support'' (TS) and ``global hierarchical collapse'' (GHC) models for molecular clouds and star formation, their respective…
