Atacama Cosmology Telescope: Observations of supermassive black hole binary candidates. Strong sinusoidal variations at 95, 147 and 225 GHz in PKS 2131$-$021 and PKS J0805$-$0111

Posted by klaurent Stanford

Kavli Affiliate: Roger Blandford | Summary:Large sinusoidal variations in the radio light curves of the blazars PKS J0805$-$0111 and PKS 2131$-$021 have recently been discovered with an 18-year monitoring programme at the Owens Valley Radio Observatory, making these systems strong supermassive black hole binary (SMBHB) candidates. The sinusoidal variations in PKS 2131$-$021 dominate its light […]

CoMBO: Conflict Mitigation via Branched Optimization for Class Incremental Segmentation

Posted by klaurent Caltech

Kavli Affiliate: Anqi Zhang| Summary:Effective Class Incremental Segmentation (CIS) requires simultaneously mitigating catastrophic forgetting and ensuring sufficient plasticity to integrate new classes. The inherent conflict above often leads to a back-and-forth, which turns the objective into finding the balance between the performance of previous~(old) and incremental~(new) classes. To address this conflict, we introduce a novel […]

pH-Sensitive Optical Nanocomposites Using Polymer-Coated Gold Nanorods

Posted by klaurent Hopkins

Kavli Affiliate: Xingde Li | Authors: Yongping Chen and Xingde Li | Summary: This study investigates the synthesis of pH-responsive, reversible nanocomposites comprising polystyrene sulfonate (PSS)-coated gold nanorods and poly(allylamine hydrochloride) (PAH)-coated gold nanorods, along with their optical properties. We observed a pH-dependent swelling/shrinking of the nanocomposites and a dramatic red-shift (~ 60 nm) of […]
