对称椭圆特征值问题的一个局部化的最优预处理Newton-Schur方法
对称椭圆 特征值问题 局部化 最优预处理 Newton-Schur
font style='font-size:12px;'>
2023/12/13
A locally optimal preconditioned Newton-Schur method is proposed for solving symmetric elliptic eigenvalue problems. Firstly, the Steklov-Poincaré operator is used to project the eigenvalue problem on...

A ripe apple falling from a tree has inspired Sir Isaac Newton to formulate a theory that describes the motion of objects subject to a force. Newton’s equations of motion tell us that a moving body ke...
How to find all roots of complex polynomials by Newton’s method
complex polynomials Newton’s method

XMM-Newton Spectra of Intermediate-Mass Black Hole Candidates: Application of a Monte Carlo Simulated Model
NGC 5408 NGC 628
font style='font-size:12px;'>
2014/12/24
We present a systematic spectral analysis of six ultraluminous X-ray sources (NGC 1313 X-1 and X-2, IC 342 X-1, Ho IX X-1, NGC 5408 X-1, and NGC 3628 X-1) observed with the XMM-Newton observatory. The...

X-ray sources IC 10
font style='font-size:12px;'>
2014/12/24
We present an X-ray study of our nearest starburst galaxy IC 10, based on XMM–Newton and Chandra observations. A list of 73 XMM–Newton and 28 Chandra detections of point-like X-ray sources in the fiel...
The XMM-Newton/Chandra monitoring campaign of the Galactic center region
Accretion accretion disks
font style='font-size:12px;'>
2014/12/24
We present the first results of our X-ray monitoring campaign on a 1.7 square degree region centered on Sgr A* using the satellites XMM-Newton and Chandra. The purpose of this campaign is to monitor t...
An XMM–Newton observation of the massive edge-on Sb galaxy NGC 2613
NGC 2613 galaxies
font style='font-size:12px;'>
2014/12/23
We present an XMM–Newton observation of the massive edge-on Sb galaxy NGC 2613. We discover that this galaxy contains a deeply embedded active nucleus with a 0.3–10 keV luminosity of 3.3 × 1040 erg s&...
VLA and XMM-Newton Observations of the SNR W41/TeV Gamma-Ray Source HESS J1834–087
