Gamma-ray flaring activity from the gravitationally lensed blazar PKS 1830-211 observed by Fermi LAT
The Fermi LAT Collaboration, A. A. Abdo, M. Ackermann +126
The Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope routinely detects the highly dust-absorbed, reddened, and MeV-peaked flat spectrum radio quasar PKS 1830…
Reentrant Landau Levels in a Dirac topological insulator
C. Kaufmann Ribeiro, J. C. Mutch, Q. Jiang +13
The quantum limit, where magnetic fields confine carriers to the lowest Landau level, is predicted to host exotic quantum phases arising from strengthened electronic correlations,…
STM Spectroscopy of ultra-flat graphene on hexagonal boron nitride
Jiamin Xue, Javier Sanchez-Yamagishi, D. Bulmash +6
Graphene has demonstrated great promise for future electronics technology as well as fundamental physics applications because of its linear energy-momentum dispersion relations whi…
Fermi-LAT Detection of Gravitational Lens Delayed Gamma-ray Flares from Blazar B0218+357
C. C. Cheung, S. Larsson, J. D. Scargle +23
Using data from the Fermi Large Area Telescope (LAT), we report the first clear gamma-ray measurement of a delay between flares from the gravitationally lensed images of a blazar.…
