Revisiting constraints on asymmetric dark matter from collapse in white dwarf stars
Heinrich Steigerwald, Valerio Marra, Stefano Profumo
The runaway collapse phase of a small dark matter cluster inside a white dwarf star encompasses a reversible stage, where heat can be transferred back and forth between nuclear and…
Type Ia Supernova Magnitude Step from the local Dark Matter Environment
Heinrich Steigerwald, Davi Rodrigues, Stefano Profumo +1
Residuals in the Hubble diagram at optical wavelengths and host galaxy stellar mass are observed to correlate in Type Ia supernovae (SNe Ia) (`magnitude step'). Among possible prog…
On the dynamical emergence of de Sitter spacetime
Christian Marinoni, Heinrich Steigerwald
We present and discuss an asynchronous coordinate system covering de Sitter spacetime, notably in a complete way in 1+1 dimensions. The new coordinates have several interesting cos…
Probing non-standard gravity with the growth index: a background independent analysis
Heinrich Steigerwald, Julien Bel, Christian Marinoni
Measurements of the growth index provide a clue as to whether Einstein's field equations encompass gravity also on large cosmic scales, those where the expansion of the univ…
