The Galactic Dynamics of Free-Floating Planets: From Ejection Kicks to Microlensing

Zara Sayed, Stefano Profumo, Nolan Smyth

Free-floating planets (FFPs) may retain dynamical signatures of the mechanisms that eject them from their host systems. We integrate collisionless FFP test particles for $10…

Right Energy, Wrong Profile: Why the 43 GeV Cluster Line Is Unlikely to Be Dark Matter

Stefano Profumo

A narrow gamma-ray line would be a distinctive signature of dark matter, but its interpretation depends as much on its spatial distribution as on its energy. We reanalyze the repor…

Low-energy antinuclei measurements for background-free indirect dark matter searches and PBH signatures

Tsuguo Aramaki, Ilias Cholis, Philip von Doetinchem +7

Light low-energy cosmic ray antinuclei constitute powerful probes for detecting dark matter or other sources of new physics in our Galaxy. This ASTRA Initiative Mission Concept rev…

Kick Velocities and Mass Function of Free-Floating Planets from Dynamical Ejection in Hierarchical Three-Body Systems

Hugh Kramer, Stefano Profumo

Free-floating planets (FFPs), also known as rogue planets, are sub-stellar objects that travel through the Galaxy unbound to any host star. Their velocity distribution carries info…

Polarized and unpolarized synchrotron emission from dark matter in extragalactic targets

Javier Reynoso-Cordova, Catherine Gibson, Stefano Profumo

We compute 95% confidence-level upper limits on the dark matter annihilation cross section and decay rate from both total-intensity and polarized synchrotron emission in five extra…

The Clustering of Little Red Dots from Ultra-Strongly Self-Interacting Dark Matter

M. Grant Roberts, Aarna Garg, Tesla Jeltema +1

We predict the effective clustering bias parameter, , at for Little Red Dots (LRDs) seeded by Ultra-Strongly Self-Interacting Dark Matter (uSIDM). From our m…
