Ultra-Heavy Dark Matter Search with Electron Microscopy of Geological Quartz
Reza Ebadi, Anubhav Mathur, Erwin H. Tanin +8
Self-interactions within the dark sector could clump dark matter into heavy composite states with low number density, leading to a highly suppressed event rate in existing direct d…
Clocking Out Superradiance Limits
Anubhav Mathur, Surjeet Rajendran, Erwin H. Tanin
The superradiant instability of black hole space-times has been used to place limits on ultra-light bosonic particles. We show that these limits are model dependent. While the init…
Gravitational wave constraints on the observable inflation
Erwin H. Tanin, Tommi Tenkanen
Gravitational waves (GW) produced in the early Universe contribute to the number of relativistic degrees of freedom, , during Big Bang Nucleosynthesis (BBN). By using…
Ability of LIGO and LISA to probe the equation of state of the early Universe
Daniel G. Figueroa, Erwin H. Tanin
The expansion history of the Universe between the end of inflation and the onset of radiation-domination (RD) is currently unknown. If the equation of state during this period is s…
Inconsistency of an inflationary sector coupled only to Einstein gravity
Daniel G. Figueroa, Erwin H. Tanin
From a model-building perspective, the inflationary sector might very well have no direct couplings to other species, apart from inevitable gravitational interactions. Within the c…
Damping of an oscillating scalar field indirectly coupled to a thermal bath
Erwin H. Tanin, Ewan D. Stewart
The damping process of a homogeneous oscillating scalar field that indirectly interacts with a thermal bath through a mediator field is investigated over a wide range of model para…
