Dynamical Heating from Dark Compact Objects and Axion Minihalos: Implications for the 21-cm Signal
Badal Bhalla, Aurora Ireland, Hongwan Liu +2
The temperature of baryons at the end of the cosmic dark ages can be inferred from observations of the 21-cm hyperfine transition in neutral hydrogen. Any energy injection from the…
Quantum Semiconductor Heterostructures for meV Axion Dark Matter Detection
Jaanita Mehrani, Tao Xu, Andrey Baydin +6
We propose a novel strategy and a new class of detectors for the direct detection of axion dark matter in the meV mass range, based on resonantly enhanced axion-photon conversion t…
From Fluctuation to Polarization: Imprints of Curvature Perturbations in CMB B-modes from Scalar-Induced Gravitational Waves
Aurora Ireland, Kuver Sinha, Tao Xu
Probing primordial curvature perturbations on small scales, beyond those accessible using cosmic microwave background (CMB) primary anisotropies and Lyman- forest data, remains…
Fast and Fewrious: Stochastic binary perturbations from fast compact objects
Badal Bhalla, Benjamin V. Lehmann, Kuver Sinha +1
Massive compact objects soften binaries. This process has been used for decades to constrain the population of such objects, particularly as a component of dark matter (DM). The ef…
Thermal Gravitons from Warm Inflation
Gabriele Montefalcone, Barmak Shams Es Haghi, Tao Xu +1
In warm inflation (WI), the persistent thermal bath that is sustained by dissipative interactions with the inflaton field produces a stochastic background of gravitational waves (G…
