A surprising excess of radio emission in extremely stable quasars: a unique clue to jet launching?

Kavli Affiliate: Feng Yuan | First 5 Authors: Wen-Yong Kang, Jun-Xian Wang, Zhen-Yi Cai, Hao-Chen Wang, Wen-Ke Ren | Summary: Quasars are generally divided into jetted radio-loud and non-jetted radio-quiet ones, but why only 10% quasars are radio loud has been puzzling for decades. Other than jet-induced-phenomena, black hole mass, or Eddington ratio, prominent difference […]

Warm and Fuzzy Dark Matter: Free Streaming of Wave Dark Matter

Kavli Affiliate: Wayne Hu | First 5 Authors: Rayne Liu, Wayne Hu, Huangyu Xiao, , | Summary: Wave or fuzzy dark matter that is produced with relativistic wavenumbers exhibits free streaming effects analogous to warm or hot particle dark matter with relativistic momenta. Axions produced after inflation provide such a warm or mildly relativistic candidate, […]

Every Poincaré gauge theory is conformal: a compelling case for dynamical vector torsion

Kavli Affiliate: Anthony Lasenby | First 5 Authors: Will Barker, Michael Hobson, Anthony Lasenby, Yun-Cherng Lin, Zhiyuan Wei | Summary: The Poincar’e gauge theory (PGT) of gravity provides a viable formulation of general relativity (Einstein-Cartan theory), and a popular model-building framework for modified gravity with torsion. Notoriously, however, the PGT terms which propagate vector torsion […]
