Weak lensing mass-richness relation of redMaPPer clusters in the LSST DESC DC2 simulations

Posted by klaurent Stanford

Kavli Affiliate: Eli Rykoff | Summary:Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, where clusters are detected through their richness, cluster-weak gravitational lensing has proven to be a powerful tool to constrain the cluster mass-richness relation. This work is conducted as part of the Dark Energy Science Collaboration […]

Phase transition in a doubly holographic model of closed $mathbf{dS_{2} }$ spacetime

Posted by dbos UCAS

Kavli Affiliate: Cheng Peng | First 5 Authors: Wen-Hao Jiang, Cheng Peng, Yun-Song Piao, , | Summary: Double holography has been proved to be a powerful method in comprehending the spacetime entanglement. In this paper we investigate the doubly holographic construction in ${mathrm{dS_{2}} }$ spacetime. We find that in this model there exists a new […]

Comparing observed properties of winds in low-luminosity active galactic nuclei with theoretical predictions

Posted by dbos Peking

Kavli Affiliate: Feng Yuan | First 5 Authors: Fangzheng Shi, Feng Yuan, Francesco Tombesi, Fu-guo XIe, | Summary: Theoretical and numerical simulations of black hole hot accretion flows have shown the ubiquitous existence of winds and predicted their properties such as velocity and mass flux. In this paper, we have summarized from literature the physical […]

A vector calculus for neural computation in the cerebellum

Posted by dbos Hopkins

Kavli Affiliate: Reza Shadmehr | Authors: Mohammad Amin Fakharian, Alden Shoup, Paul Hage, Hisham Elseweifi and Reza Shadmehr | Summary: Null space theory predicts that a neuron will often generate spikes not to produce behavior, but to prevent another neuron’s impact on behavior. Here, we present a direct test of this theory in the brain. […]

Long-Term X-ray Variability on the Benchmark YSO HL Tau

Posted by klaurent MIT

Kavli Affiliate: Moritz Guenther | Summary:HL Tau is one of the most well-studied Class I young stellar objects, including frequent observations at near- and mid-infrared, (sub-) millimeter, and X-ray wavelengths. We present the results of an X-ray variability monitoring campaign with XMM-Newton in 2020 and X-ray gratings spectroscopy from Chandra/HETGS in 2018. We find that […]
