Strong Lensing analysis of SPT-CLJ2325$-$4111 and SPT-CLJ0049$-$2440, two Powerful Cosmic Telescopes ($R_E > 40”$) from the SPT Clusters Sample

Posted by Chicago

Kavli Affiliate: Michael D. Gladders | First 5 Authors: Guillaume Mahler, Keren Sharon, Matthew Bayliss, Lindsey. E. Bleem, Mark Brodwin | Summary: We report the results from a study of two massive ($M_{500c} > 6.0 times 10^{14} M_{odot}$) strong lensing clusters selected from the South Pole Telescope cluster survey for their high Einstein radius ($R_E […]

Twinkle: A GPU-based binary-lens microlensing code with contour integration method

Posted by Peking

Kavli Affiliate: Lile Wang | First 5 Authors: Suwei Wang, Lile Wang, Subo Dong, , | Summary: With the rapidly increasing rate of microlensing planet detections, microlensing modeling software faces significant challenges in computation efficiency. Here, we develop the Twinkle code, an efficient and robust binary-lens modeling software suite optimized for heterogeneous computing devices, especially […]

The superior colliculus gates dopamine responses to conditioned stimuli in visual classical conditioning

Posted by dbos This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Yan-Feng Zhang, Jean-Philippe Dufour, Peter Zatka-Haas, Peter Redgrave, Melony J Black, Armin Lak, Ed Mann, Stephanie J Cragg, Wickliffe Abraham and John NJ Reynolds | Summary: In classical Pavlovian conditioning, it is well-established that midbrain dopamine neurons respond to conditioned stimuli (CS) that predict a reward. However, how the […]

Targeted stimulation of motor cortex neural ensembles drives learned movements

Posted by dbos This Week: Neuroscience, UCSD / Salk

Kavli Affiliate: Takaki Komiyama | Authors: An Wu, Qiyu Chen, Bin Yu, Soyoung Chae, Zijing Tan, Assaf Ramot and Takaki Komiyama | Summary: During the execution of learned motor skills, the neural population in the layer 2/3 (L2/3) of the primary motor cortex (M1) expresses a reproducible spatiotemporal activity pattern. It is debated whether M1 […]

Non-local modular flows across deformed null-cuts

Posted by dbos This Week: Theoretical Physics, UCAS

Kavli Affiliate: Huajia Wang | First 5 Authors: Guan-Cheng Lu, Huajia Wang, , , | Summary: Modular flows probe important aspects of the entanglement structures, especially those of QFTs, in a dynamical framework. Despite the expected non-local nature in the general cases, the majority of explicitly understood examples feature local space-time trajectories under modular flows. […]
