Cosmological evolution with decaying dark matter: an integral-equation approach
Nanoom Lee, Anna Bencke, Marc Kamionkowski +1
We present CLASSIER-DDM, an extension of the Boltzmann solver CLASSIER that implements the decaying dark matter (DDM) model via its integral-equation approach. The code handles gen…

Constraints with CMB lensing on dark matter decays to massive decay products
Anna Bencke, Nanoom Lee, Marc Kamionkowski
Motivated by the recent measurements by the Dark Energy Spectroscopic Instrument (DESI) which suggest a late-time matter density approximately 5\% lower than that inferred from Pla…

Hidden Symmetry in the Double Copy
Adam Ball, Anna Bencke, Yaxi Chen +1
We show that the Killing tensor of the Kerr spacetime has an analogue in the gauge theory solution related to it by the classical double copy. This hidden symmetr…
