The Importance of Galaxy-Wide Star Formation in Driving Winds at z~1
Weichen Wang, Susan A. Kassin, S. M. Faber +11
In this work, we study winds for a representative sample of 86 star-forming galaxies (SFGs) at z~1 with , by measuring the Mg II line profiles…
Projected principal component analysis in factor models
Jianqing Fan, Yuan Liao, Weichen Wang
This paper introduces a Projected Principal Component Analysis (Projected-PCA), which employs principal component analysis to the projected (smoothed) data matrix onto a given line…
Volatility prediction comparison via robust volatility proxies: An empirical deviation perspective
Weichen Wang, Ran An, Ziwei Zhu
Volatility forecasting is crucial to risk management and portfolio construction. One particular challenge of assessing volatility forecasts is how to construct a robust proxy for t…
The hydrodynamical response of cold circumgalactic clouds to quasar radiation
Nicolas Ledos, Sebastiano Cantalupo, Titouan Lazeyras +8
Recent simulations increasingly resolve the small-scale structure of the circumgalactic medium (CGM), but the dynamical impact of ionising radiation on its cold K component…
Resolving the physics of Quasar Ly Nebulae (RePhyNe): I. Constraining Quasar host halo masses through Circumgalactic Medium kinematics
Stephanie de Beer, Sebastiano Cantalupo, Andrea Travascio +8
Ly nebulae ubiquitously found around z>2 quasars can supply unique constraints on the properties of the Circumgalactic Medium, such as its density distribution, provided the qu…
Goal-Oriented Joint Source-Channel Coding: Distortion-Classification-Power Trade-off
Andriy Enttsel, Weichen Wang, Mauro Mangia +2
Joint source-channel coding is a compelling paradigm when low-latency and low-complexity communication is required. This work proposes a theoretical framework that integrates class…
