Directly Imaging the Cooling Flow in the Phoenix Cluster

Kavli Affiliate: Michael McDonald | First 5 Authors: Michael Reefe, Michael McDonald, Marios Chatzikos, Jerome Seebeck, Richard Mushotzky | Summary: In the centers of many galaxy clusters, the hot ($sim$10$^7$ K) intracluster medium (ICM) can become dense enough that it should cool on short timescales. However, the low measured star formation rates in massive central […]

How does the restriction of representations change under translations? A story for the general linear groups and the unitary groups

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We present a new approach to symmetry breaking for pairs of real forms of $(GL(n, mathbb{C}), GL(n-1, mathbb{C}))$. While translation functors are a useful tool for studying a family of representations of a single reductive group $G$, when applied […]

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

Kavli Affiliate: Eli S. Rykoff | First 5 Authors: Constantin Payerne, Zhuowen Zhang, Michel Aguena, CĂ©line Combet, Thibault Guillemin | Summary: Cluster scaling relations are key ingredients in cluster abundance-based cosmological studies. In optical cluster cosmology, weak gravitational lensing has proven to be a powerful tool to constrain the cluster mass-richness relation. This work is […]

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

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

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 […]
