Kavli Affiliate: Wendy Freedman | First 5 Authors: Ilaria Lonoce, Wendy Freedman, Anja Feldmeier-Krause, , | Summary: The Hydra I cluster offers an excellent opportunity to study and compare the relic old stellar populations in the core of its two brightest galaxies. In addition, the differing kinematics of the two galaxies allows a test of […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Shunsaku Nagasawa, Takahiro Minami, Shin Watanabe, Tadayuki Takahashi, | Summary: We propose a new strip configuration for CdTe X-ray detectors, named "Wide-gap CdTe strip detector", in which the gap between adjacent strips is much wider than the width of each strip. It has been known that the […]

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Tobias J. Looser, Francesco D’Eugenio, Roberto Maiolino, Joris Witstok, Lester Sandles | Summary: Local and low-redshift ($z$<$3$) galaxies are known to broadly follow a bimodal distribution: actively star forming galaxies with relatively stable star-formation rates, and passive systems. These two populations are connected by galaxies in relatively […]
Kavli Affiliate: Mark Vogelsberger | First 5 Authors: Natalí S. M. de Santi, Helen Shao, Francisco Villaescusa-Navarro, L. Raul Abramo, Romain Teyssier | Summary: We train graph neural networks to perform field-level likelihood-free inference using galaxy catalogs from state-of-the-art hydrodynamic simulations of the CAMELS project. Our models are rotational, translational, and permutation invariant and do […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Mohammad Ali Gorji, Misao Sasaki, , , | Summary: Cosmological stochastic gravitational waves (GWs) induced by a spectator field are usually expected to have an amplitude very small compared with those generated by the curvature perturbation, or equivalently by a field dominating the universe. On the contrary […]
Kavli Affiliate: Linhua Jiang | First 5 Authors: Siwei Zou, Linhua Jiang, Zheng Cai, John Moustakas, Zechang Sun | Summary: We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument (DESI) survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam (HSC) field. We […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We consider Lifshitz criticality (LC) with the dynamical critical exponent $z=2$ in one-dimensional interacting fermions with a filled Dirac Sea. We report that interactions have crucial effects on Lifshitz criticality. Single particle excitations are destabilized by interaction and decay into […]
Kavli Affiliate: Jing Wang | First 5 Authors: Zhiqiang Kou, Yuheng Jia, Jing Wang, Xin Geng, | Summary: Label distribution learning (LDL) trains a model to predict the relevance of a set of labels (called label distribution (LD)) to an instance. The previous LDL methods all assumed the LDs of the training instances are accurate. […]
