Hints of self-interacting dark matter from strong gravitational lensing
Daniel Gilman, Kalliopi Petraki, Thomas Pignard +3
An analysis of 29 quadruply imaged quasars hints at dark matter halo densities consistent with gravothermal core collapse, a key prediction of self-interacting dark matter. We inte…
Variable-phase methods and data for long-range scattering
Marcos M. Flores, Kalliopi Petraki, Thomas Pignard
Long-range interactions play an important role in dark-matter phenomenology, affecting the relic abundance, indirect-detection signals, and structure formation on galactic scales.…
DDELenS: Tomographic Weak Lensing Simulations with Dynamical Dark Energy
Shu-Fan Chen, J. Colin Hill, Zoltán Haiman
We present a suite of 128 cosmological simulations in CDM cosmologies with massive neutrinos, designed to enable simulation-based inference of dynamical dark energy paramet…
Planets surviving common envelope evolution should be rare, massive, and orbit very close to their host star
Yadira S. Gaibor, Andrew Vanderburg, Juliette C. Becker +3
The discovery of exoplanets around white dwarfs uniquely informs our understanding of planetary survival through stellar evolution. Common Envelope (CE) evolution is one of the pro…
