Spectral Factorization of Non-Classical Information Structures Under Feedback
Structures Under Feedback Non-Classical Information

2015/6/19
We consider general linear systems under feedback. We restrict our attention to non-classical information structures for which the optimal control policies can be found via a convex optimization probl...
An Explicit Solution for Optimal Two-Player Decentralized Control over a TCP Erasure Channel with State Feedback
Decentralized Control over Explicit Solution
font style='font-size:12px;'>
2015/6/19
We develop an optimal controller synthesis algorithm for decentralized control problems where control actions are transmitted through TCP-like erasure channels. We consider a simple two-player interco...
Optimal Controller Synthesis for a Decentralized Two-Player System with Partial Output Feedback
Partial Output Feedback Two-Player System

The conference will be held at Jianguo Hotel. This hotel locates in downtown Shanghai, close to Subway Xujiahui station, and is also about 200 meters away from Shanghai Astronomical Observatory.
Star formation and feedback in smoothed particle hydrodynamic simulations - I. Isolated galaxies
star formation supernova feedback
font style='font-size:12px;'>
2014/12/24
We present an analysis of star formation and feedback recipes appropriate for galactic smoothed particle hydrodynamics simulations. Using an isolated Milky Way-like galaxy, we constrain these recipes ...
Accretion, feedback and galaxy bimodality: a comparison of the GalICS semi-analytic model and cosmological SPH simulations
cooling fl ows evolution
font style='font-size:12px;'>
2014/12/23
We compare the galaxy population of a smoothed particle hydrodynamics (SPH) simulation to those predicted by the GalICS (Galaxies In Cosmological Simulations) N-body + semi-analytic model and a stripp...
Self-regulated fueling of galaxy centers: Evidence for star formation feedback

2014/12/23
Using new, high-resolution interferometric observations of the CO and HCN molecules, we directly compare the molecular and ionized components of the interstellar medium in the center of the nearby spi...
Confronting feedback simulations with observations of hot gas in elliptical galaxies
X-ray elliptical galaxies hot gas galaxy evolution
font style='font-size:12px;'>
2014/12/23
Elliptical galaxies comprise primarily old stars, which collectively generate a long-lasting feedback via stellar mass-loss and Type Ia SNe. This feedback can be traced by X-ray-emitting hot gas in an...
Feedback from galactic stellar bulges and hot gaseous haloes of galaxies
bulges ISM
font style='font-size:12px;'>
2014/12/23
We demonstrate that the feedback from stellar bulges can, in principle, play an essential role in shaping the halo gas of galaxies with substantial bulge components by conducting 1D hydrodynamical sim...
Galaxies in a simulated Lambda CDM universe - II. Observable properties and constraints on feedback
feedback cluster
font style='font-size:12px;'>
2014/12/23
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z= 0 galaxy population. We confirm previous findings that models without str...
OBSERVATIONS OF STARBURST GALAXIES WITH FAR-ULTRAVIOLET SPECTROGRAPHIC EXPLORER: GALACTIC FEEDBACK IN THE LOCAL UNIVERSE
starburst halos
font style='font-size:12px;'>
2014/12/22
We have analyzed FUSE (905-1187 ? spectra of a sample of 16 local starburst galaxies. These galaxies cover almost three orders of magnitude in star-formation rates and over two orders of magnitude in ...
Feedback and Recycled Wind Accretion: Assembling the z = 0 Galaxy Mass Function
Feedback and Recycled Wind Galaxy Mass
font style='font-size:12px;'>
2014/12/22
We analyse cosmological hydrodynamic simulations that include observationally-constrained prescriptions for galactic outflows. If these simulated winds accurately represent winds in the real Universe,...
Galactic coronae in the intracluster environment: semiconfined stellar-feedback-driven outflows

2014/12/20
Recently X-ray observations have shown the regular presence of compact galactic coronae around intermediate-mass spheroid galaxies embedded in the intracluster/intragroup medium (ICM). We conduct 2D h...
