Soft self-assembly of Weyl materials for light and sound

Kavli Affiliate: Ulrich Wiesner | First 5 Authors: Michel Fruchart, Seung-Yeol Jeon, Kahyun Hur, Vadim Cheianov, Ulrich Wiesner | Summary: Soft materials can self-assemble into highly structured phases which replicate at the mesoscopic scale the symmetry of atomic crystals. As such, they offer an unparalleled platform to design mesostructured materials for light and sound. Here, […]

Simulating the galaxy cluster “El Gordo”: gas motion, kinetic Sunyaev-Zel’dovich signal, and X-ray line features

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Congyao Zhang, Qingjuan Yu, Youjun Lu, , | Summary: The massive galaxy cluster "El Gordo" (ACT-CL J0102–4915) is a rare merging system with a high collision speed suggested by multi-wavelength observations and the theoretical modeling. Zhang et al. (2015) propose two types of mergers, a nearly head-on […]

Glimpse of the highly obscured HMXB IGR J16318-4848 with Hitomi

Kavli Affiliate: Marshall W. Bautz | First 5 Authors: Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu, Fumie Akimoto, Steven W. Allen | Summary: We report a Hitomi observation of IGR J16318-4848, a high-mass X-ray binary system with an extremely strong absorption of N_H~10^{24} cm^{-2}. Previous X-ray studies revealed that its spectrum is dominated by strong fluorescence […]

Serendipitous discovery of quadruply-imaged quasars: two diamonds

Kavli Affiliate: Paul L. Schechter | First 5 Authors: John R. Lucey, Paul L. Schechter, Russell J. Smith, Timo Anguita, | Summary: Gravitationally lensed quasars are powerful and versatile astrophysical tools, but they are challengingly rare. In particular, only ~25 well-characterized quadruple systems are known to date. To refine the target catalogue for the forthcoming […]
