DESI survey validation data in the COSMOS/HSC field: Cool gas trace main sequence star-forming galaxies at the cosmic noon

Posted by dbos Peking

Kavli Affiliate: Linhua Jiang | First 5 Authors: Siwei Zou, Linhua Jiang, Zheng Cai, John Moustakas, Zechang Sun | Summary: We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument (DESI) survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam (HSC) field. We […]

Quantum $z=2$ Lifshitz criticality in one-dimensional interacting fermions

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]
