Long-Lived Light Mediators from Higgs boson Decay at HL-LHC, FCC-hh and a Proposal of Dedicated LLP Detectors for FCC-hh

Posted by klaurent Tokyo

Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Biplob Bhattacherjee, Shigeki Matsumoto, Rhitaja Sengupta, , | Summary: We study the pair production of the long-lived mediator particles from the decay of the SM Higgs boson and their subsequent decay into standard model particles. We compute the projected sensitivity, both model-independently and with a minimal model, […]

VLA Radio Study of a Sample of Nearby X-ray and Optically Bright Early-Type Galaxies

Posted by klaurent Stanford

Kavli Affiliate: Steven W. Allen | First 5 Authors: Romana Grossová, Norbert Werner, Francesco Massaro, Kiran Lakhchaura, Tomáš Plšek | Summary: Many massive early-type galaxies host central radio sources and hot X-ray atmospheres indicating the presence of radio-mechanical active galactic nucleus (AGN) feedback. The duty cycle and detailed physics of the radio-mode AGN feedback is […]

Cosmological inference from the emulator based halo model II: Joint analysis of galaxy-galaxy weak lensing and galaxy clustering from HSC-Y1 and SDSS

Posted by Tokyo

Kavli Affiliate: Masahiro Takada | First 5 Authors: Hironao Miyatake, Sunao Sugiyama, Masahiro Takada, Takahiro Nishimichi, Masato Shirasaki | Summary: We present high-fidelity cosmology results from a blinded joint analysis of galaxy-galaxy weak lensing ($Delta!Sigma$) and projected galaxy clustering ($w_{rm p}$) measured from the Hyper Suprime-Cam Year-1 (HSC-Y1) data and spectroscopic Sloan Digital Sky Survey […]

The THESAN project: predictions for multi-tracer line intensity mapping in the epoch of reionization

Posted by klaurent MIT

Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Rahul Kannan, Aaron Smith, Enrico Garaldi, Xuejian Shen, Mark Vogelsberger | Summary: Line intensity mapping (LIM) is rapidly emerging as a powerful technique to study galaxy formation and cosmology in the high-redshift Universe. We present LIM estimates of select spectral lines originating from the interstellar medium (ISM) […]
