Constraining Quasar Feedback from Analysis of the Hydrostatic Equilibrium of the Molecular Gas in Their Host Galaxies

Posted by klaurent Peking

Kavli Affiliate: Jinyi Shangguan | Summary:We investigate the kinematics and dynamics of the molecular and ionized gas in the host galaxies of three Palomar-Green quasars at low redshifts, benefiting from the archival millimeter-wave interferometric and optical integral field unit data. We study the kinematics of both cold molecular and hot ionized gas by analyzing the […]

Ensemble Kalman Filter Data Assimilation Into Surface Flux Transport Model To Infer Surface Flows: An Observing System Simulation Experiment

Posted by klaurent Stanford

Kavli Affiliate: J. Todd Hoeksema | Summary:Knowledge of the global magnetic field distribution and its evolution on the Sun’s surface is crucial for modeling the coronal magnetic field, understanding solar wind dynamics, computing the heliospheric open flux distribution and predicting solar cycle strength. As the far side of the Sun cannot be observed directly and […]

DiffFluid: Plain Diffusion Models are Effective Predictors of Flow Dynamics

Posted by dbos Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Dongyu Luo, Jianyu Wu, Jing Wang, Hairun Xie, Xiangyu Yue | Summary: We showcase the plain diffusion models with Transformers are effective predictors of fluid dynamics under various working conditions, e.g., Darcy flow and high Reynolds number. Unlike traditional fluid dynamical solvers that depend on complex architectures […]

Revealing the state transition of Cen X-3 at high spectral resolution with Chandra

Posted by dbos MIT

Kavli Affiliate: Norbert Schulz | First 5 Authors: Graciela Sanjurjo-Ferrín, Jose Miguel Torrejón, Lida Oskinova, Konstantin Postnov, Jose Joaquín Rodes-Roca | Summary: Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportunity textit{Chandra} observation made during […]

Kavli Affiliate: Norbert Schulz | Summary:Cen X-3 is a compact, high-mass X-ray binary (HMXRB), likely powered by Roche lobe overflow. We present a phase-resolved X-ray spectral and timing analysis of a target of opportunity textitChandra observation made during a low-flux to high-flux transition. The high-resolution spectra allow us to delve into the events that occurred […]

First Resolution of Microlensed Images of a Binary-Lens Event

Posted by dbos Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary-lens perturbations, complicating the analysis, but the […]

The light curves show weak binary-lens perturbations, complicating the analysis, but the joint modeling with the VLTI data breaks several degeneracies, arriving at a strongly favored solution.
