The optical spectropolarimetric behaviour of a selection of high-energy blazars

Autor: Barnard, J., van Soelen, B., Acharya, S., Böttcher, M., Britto, R. J., Cooper, J., Buckley, D. A. H., Martin-Carrillo, A., Vaidya, B., van der Westhuizen, I. P., Zacharias, M.

At optical/ultraviolet energies, blazars display an underlying thermal (unpolarized) contribution from the accretion disc, torus and line emitting regions, diluting the polarized emission from the jet-component. Optical polarimetry can be used to dis

In July 2021, PKS 1510-089 exhibited a significant flux drop in the high-energy gamma-ray (by a factor 10) and optical (by a factor 5) bands and remained in this low state throughout 2022. Similarly, the optical polarization in the source vanished, r

Social reward and nonsocial reward processing across the adult lifespan: An interim multi-echo fMRI and diffusion dataset

Social relationships change across the lifespan as social networks narrow and motivational priorities shift. These changes may affect, or reflect, differences in how older adults make decisions related to processing social and non-social rewards. Whi

Compartmentalizing the cuprate strange metal

It has long been recognized that the key to unlocking the mystery of cuprate high-Tc superconductivity lies in understanding the anomalous normal state from which pairs form and condense. While many of its defining properties have been identified, th

Hall effect and quantum oscillation measurements on high temperature cuprate superconductors show that underdoped compositions have a small Fermi surface pocket whereas when heavily overdoped, the pocket increases dramatically in size. The origin of
