Radial Gas Flows in Colliding Galaxies: Connecting Simulations and Observations
interactions kinematics and dynamics
2014/12/24
We investigate the detailed response of gas to the formation of transient and long-lived dynamical structures induced in the early stages of a disk-disk collision and identify observational signatures...
RADIAL DISTRIBUTION OF STARS, GAS AND DUST IN SINGS GALAXIES. I. SURFACE PHOTOMETRY AND MORPHOLOGY
photometry fundamental parameters
2014/12/23
We present ultraviolet through far-infrared (FIR) surface brightness profiles for the 75 galaxies in the Spitzer Infrared Nearby Galaxies Survey (SINGS). The imagery used to measure the profiles inclu...
Radial distribution of stars, gas and dust in SINGS galaxies II. DERIVED DUST PROPERTIES
dust extinction ISM
2014/12/23
We present a detailed analysis of the radial distribution of dust properties in the SINGS sample, performed on a set of ultraviolet (UV), infrared (IR), and H I surface brightness profiles, combined w...
Verification of SpacePy's radial diffusion radiation belt model
SpacePy's radial diffusion radiation belt model
2014/12/11
Model verification, or the process of ensuring that the prescribed equations are properly solved, is a necessary step in code development. Careful, quantitative verification guides users when selectin...
A Hierarchical Spherical Radial Quadrature Algorithm for Multilevel GLMMS, GSMMS, and Gene Pathway Analysis
Generalized Semiparametric Mixed Model multilevel Spherical Radial splines
2014/12/8
The first part of my thesis is concerned with estimation for longitudinal data using generalized semi-parametric mixed models and multilevel generalized linear mixed models for a binary response. Like...
Optimal Recovery of Holomorphic Functions from Inaccurate Information about Radial Integration
Approximation Optimal Recovery Holomorphic
2013/1/30
This paper addresses the optimal recovery of functions from Hilbert spaces of functions on the unit disc. The estimation, or recovery, is performed from inaccurate information given by integration alo...
Semi-infinite paths of the 2d-Radial Spanning Tree
stochastic geometry random tree semi-infinite path asymptotic direction competition interface
2012/6/9
We study semi-infinite paths of the radial spanning tree (RST) of a Poisson point process in the plane. We first show that the expectation of the number of intersection points between semi-infinite pa...

Classification radial solutions focusing energy-critical wave equation Analysis of PDEs
2012/4/17
In this paper, we describe the asymptotic behaviour of globally defined solutions and of bounded solutions blowing up in finite time of the radial energy-critical focusing non-linear wave equation in ...
Response to Climate Change about Radial Growth of Larix gmelinii Main Forest Types in Daxing’anling Mountains
Larix gmelinii Chronology Climate Change Response
2011/12/16
Tree-ring width chronologies were developed for Larix gmelini of main forest types in Daxinganling mountains, and by correlation analysis and response function analysis illustrate difference empact of...
The Radial Velocity Signature of Tides Raised in Stars Hosting Exoplanets
stars: planetary systems – stars: solar type – hydrodynamics – waves – planet-star interactions
2011/10/18
Close-in, massive exoplanets raise significant tides in their stellar hosts. We compute the radial velocity (RV) signal due to this fluid motion in the equilibrium tide approximation. The predicted ra...

2011/10/19
Stellar activity induces apparent radial velocity (RV) variations in late-type main-sequence stars that may hamper the detection of low-mass planets and the measurement of their mass. We use simultane...
In cool stars that oscillate like the Sun, non-radial modes become mixed as the stars evolve. The mixing is caused by the coupling between g-modes in the stellar core and p-modes in the envelope, whic...
