Detecting Acoherence in Radiation Fields

Kavli Affiliate: Frank Wilczek | First 5 Authors: Sreenath K. Manikandan, Frank Wilczek, , , | Summary: We propose simple quantitative criteria, based on counting statistics in resonant harmonic detectors, that probe the quantum mechanical character of radiation fields. They provide, in particular, practical means to test the null hypothesis that a given field is […]

Intermediate-Mass Black Holes in Green Pea Galaxies (IMBH-GP) I: a Candidate Sample from LAMOST and SDSS

Kavli Affiliate: Linhua Jiang | First 5 Authors: Ruqiu Lin, Zhen-Ya Zheng, Fang-Ting Yuan, Jun-Xian Wang, Chunyan Jiang | Summary: The scaling relation of central massive black holes (MBHs) and their host galaxies is well-studied for supermassive BHs (SMBHs, $M_{rm BH} ge 10^6, M_{rm odot}$). However, this relation has large uncertainties in the mass range […]
