Towards a Muon Collider

Kavli Affiliate: Gordan Krnjaic | First 5 Authors: Carlotta Accettura, Dean Adams, Rohit Agarwal, Claudia Ahdida, Chiara Aimè | Summary: A muon collider would enable the big jump ahead in energy reach that is needed for a fruitful exploration of fundamental interactions. The challenges of producing muon collisions at high luminosity and 10 TeV centre […]

Constraints on axion-like polarization oscillations in the cosmic microwave background with POLARBEAR

Kavli Affiliate: Nobuhiko Katayama | First 5 Authors: The POLARBEAR Collaboration, Shunsuke Adachi, Tylor Adkins, Kam Arnold, Carlo Baccigalupi | Summary: Very light pseudoscalar fields, often referred to as axions, are compelling dark matter candidates and can potentially be detected through their coupling to the electromagnetic field. Recently a novel detection technique using the cosmic […]

Angular spectrum of quantum fluctuations in causal structure

Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, Ohkyung Kwon, Nathaniel Selub, , | Summary: Scaling arguments are used to constrain the angular spectrum of distortions on boundaries of macroscopic causal diamonds, produced by Planck-scale vacuum fluctuations of causally-coherent quantum gravity. The small-angle spectrum of displacement is derived from a form of scale […]

Improved bounds on the bosonic dark matter with pulsars in the Milky Way

Kavli Affiliate: Lijing Shao | First 5 Authors: Dicong Liang, Lijing Shao, , , | Summary: Neutron stars (NSs) can be used to constrain dark matter (DM) since a NS can transform into a black hole (BH) if it captures sufficient DM particles and exceeds the Chandrasekhar limit. We extend earlier work and for the […]

Active galactic nuclei feedback in an elliptical galaxy (III): the impacts and fate of cosmological inflow

Kavli Affiliate: Yingjie Peng | First 5 Authors: Bocheng Zhu, Feng Yuan, Suoqing Ji, Yingjie Peng, Luis C. Ho | Summary: The cosmological inflow of a galaxy is speculated to be able to enter the galaxy and enhance the star formation rate (SFR) and black hole accretion rate (BHAR). In this paper, by performing high-resolution […]
