Cross-correlation of the Polarizations of the 21-cm and Cosmic Microwave Backgrounds
Lingyuan Ji, Selim C. Hotinli, Marc Kamionkowski
The polarization of the 21-cm radiation from the epoch of reionization arises from Thomson scattering of 21-cm photons from free electrons and provides information that complements…
What causes the absence of pulsations in Central Compact Objects in Supernova Remnants?
Qi Wu, Adriana M. Pires, Axel Schwope +3
Most young neutron stars belonging to the class of Central Compact Objects in supernova remnants (CCOs) do not have known periodicities. We investigated seven such CCOs to understa…
Thermal Perturbations from Cosmological Constant Relaxation
Lingyuan Ji, David E. Kaplan, Surjeet Rajendran +1
We probe the cosmological consequences of a recently proposed class of solutions to the cosmological constant problem. In these models, the universe undergoes a long period of infl…
Wave Dark Matter Non-minimally Coupled to Gravity
Lingyuan Ji
We consider a model where a light scalar field (with mass ), conjectured to be dark matter, has a non-minimal coupling to gravity. In the non-relativistic l…
