Constraining primordial oscillations and inflationary particle production with Planck, ACT DR6, and DESI DR2
Simran K. Nerval, Renee Hlozek, Hidde T. Jense +1
Non-standard inflationary models often predict oscillatory features in the primordial power spectrum. We present constraints on general oscillatory templates for primordial power s…
Probing inflationary particle production with the CMB power spectrum
Hidde T. Jense, Luca H. Abu El-Haj, J. Colin Hill +1
Particle production is common to many microphysical models of inflation and can imprint observable features in the cosmic microwave background (CMB) anisotropies. We consider a sce…
The Atacama Cosmology Telescope: Probing new signatures of ultralight axions with gravitational lensing
Alex Laguë, Keir K. Rogers, Mathew S. Madhavacheril +14
Ultralight axions (ULAs) are well-motivated dark matter particle candidates that arise in many extensions of the Standard Model of particle physics. ULAs with mass $m_\mathrm{a} \l…
