Shaving off Black Hole Soft Hair
Mehrdad Mirbabayi, Massimo Porrati
A recent, intriguing paper by Hawking, Perry and Strominger suggests that soft photons and gravitons can be regarded as black hole hair and may be relevant to the black hole inform…
Productive Interactions: heavy particles and non-Gaussianity
Raphael Flauger, Mehrdad Mirbabayi, Leonardo Senatore +1
We analyze the shape and amplitude of oscillatory features in the primordial power spectrum and non-Gaussianity induced by periodic production of heavy degrees of freedom coupled t…
Tensor Squeezed Limits and the Higuchi Bound
Lorenzo Bordin, Paolo Creminelli, Mehrdad Mirbabayi +1
We point out that tensor consistency relations-i.e. the behavior of primordial correlation functions in the limit a tensor mode has a small momentum-are more universal than scalar…
Weinberg Soft Theorems from Weinberg Adiabatic Modes
Mehrdad Mirbabayi, Marko Simonović
Soft theorems for the scattering of low energy photons and gravitons and cosmological consistency conditions on the squeezed-limit correlation functions are both understood to be c…
LSS constraints with controlled theoretical uncertainties
Tobias Baldauf, Mehrdad Mirbabayi, Marko Simonović +1
Forecasts and analyses of cosmological observations often rely on the assumption of a perfect theoretical model over a defined range of scales. We explore how model uncertainties a…
Radio Emission from Red-Giant Hot Jupiters
Yuka Fujii, David S. Spiegel, Tony Mroczkowski +5
When planet-hosting stars evolve off the main sequence and go through the red-giant branch, the stars become orders of magnitudes more luminous and, at the same time, lose mass at…
