Evolutionary Paths of Active Galactic Nuclei and Their Host Galaxies

Kavli Affiliate: Luis C. Ho | First 5 Authors: Ming-Yang Zhuang, Luis C. Ho, , , | Summary: The tight correlations between the masses of supermassive black holes (BHs) and the properties of their host galaxies suggest that BHs coevolve with galaxies. However, what is the link between BH mass ($M_{rm BH}$) and the properties […]

Detecting a long lived false vacuum with quantum quenches

Kavli Affiliate: Frank Wilczek | First 5 Authors: Gianluca Lagnese, Federica Maria Surace, Sid Morampudi, Frank Wilczek, | Summary: Distinguishing whether a system supports alternate low-energy (locally stable) states — stable (true vacuum) versus metastable (false vacuum) — by direct observation can be difficult when the lifetime of the state is very long but otherwise […]

Radio Pulsar B0950$+$08: Radiation in Magnetosphere and Sparks above Surface

Kavli Affiliate: Kejia Lee | First 5 Authors: Zhengli Wang, Jiguang Lu, Jinchen Jiang, Shunshun Cao, Kejia Lee | Summary: We observed the nearby 100$%$-duty-cycle radio pulsar B0950+08 using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We obtained the polarization profile for its entire rotation, which enabled us to investigate its magnetospheric radiation geometry and […]

Extreme Energy Cosmic Rays “Treasure Maps”: a new methodology to unveil the nature of cosmic accelerators

Kavli Affiliate: Roger Blandford | First 5 Authors: NoĆ©mie Globus, Anatoli Fedynitch, Roger Blandford, , | Summary: Extreme Energy Cosmic Rays, EECRs — cosmic rays with energies beyond the GZK cutoff (i.e. greater than 100 EeV) are scarce. Only a few of such events have been detected by air shower experiments and the nature of […]
