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 […]

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 […]

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

Kavli Affiliate: Moritz Guenther | First 5 Authors: Steven M. Silverberg, Scott J. Wolk, David A. Principe, P. Christian Schneider, Hans 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 […]

Gamma-ray emission from decays of boosted nuclei in proto-magnetar jets

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Sean Heston, Nick Ekanger, Shunsaku Horiuchi, , | Summary: We examine the detectability of $gamma$-ray emission originating from the radioactive decays of unstable nuclei that are synthesized in relativistic outflows launched in magneto-rotational core-collapse supernovae. The observed lines have enhanced energies due to the Lorentz boosted nuclei […]

Geometric Interpretations of the $k$-Nearest Neighbour Distributions

Kavli Affiliate: Tom Abel | First 5 Authors: Kwanit Gangopadhyay, Arka Banerjee, Tom Abel, , | Summary: The $k$-Nearest Neighbour Cumulative Distribution Functions are measures of clustering for discrete datasets that are fast and efficient to compute. They are significantly more informative than the 2-point correlation function. Their connection to $N$-point correlation functions, void probability […]

Shedding light on the star formation rate-halo accretion rate connection and halo quenching mechanism via DECODE, the Discrete statistical sEmi-empiriCal mODEl

Kavli Affiliate: Yingjie Peng | First 5 Authors: Hao Fu, Lumen Boco, Francesco Shankar, Andrea Lapi, Mohammadreza Ayromlou | Summary: Aims: The relative roles of the physical mechanisms involved in quenching galaxy star formation are still unclear. We tackle this fundamental problem with our cosmological semi-empirical model DECODE (Discrete statistical sEmi-empiriCal mODEl), designed to predict […]
