Picosecond Laser Ablation of Millimeter-Wave Subwavelength Structures on Alumina and Sapphire

Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Qi Wen, Elena Fadeeva, Shaul Hanany, Jürgen Koch, Tomotake Matsumura | Summary: We use a 1030 nm laser with 7 ps pulse duration and average power up to 100 W to ablate pyramid-shape subwavelength structures (SWS) on alumina and sapphire. The SWS give an effective and cryogenically […]

Modelling the Multiwavelength Variability of Mrk 335 using Gaussian Processes

Kavli Affiliate: Erin Kara | First 5 Authors: Ryan-Rhys Griffiths, Jiachen Jiang, Douglas J. K. Buisson, Dan R. Wilkins, Luigi C. Gallo | Summary: The optical and UV variability of the majority of AGN may be related to the reprocessing of rapidly-changing X-ray emission from a more compact region near the central black hole. Such […]

Mechanisms of Andreev reflection in quantum Hall graphene

Kavli Affiliate: Anton R. Akhmerov | First 5 Authors: Antonio L. R. Manesco, Ian Matthias Flór, Chun-Xiao Liu, Anton R. Akhmerov, | Summary: We simulate a hybrid superconductor-graphene device in the quantum Hall regime to identify the origin of downstream resistance oscillations in a recent experiment [Zhao et. al. Nature Physics 16, (2020)]. In addition […]

On the Mass Loading of AGN-Driven Outflows in Elliptical Galaxies and Clusters

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Yu Qiu, Brian R. McNamara, Tamara Bogdanovic, Kohei Inayoshi, Luis C. Ho | Summary: Outflows driven by active galactic nuclei (AGN) are an important channel for accreting supermassive black holes (SMBHs) to interact with their host galaxies and clusters. Properties of the outflows are however poorly constrained […]
