DISTANCE DETERMINATION TO THE CRAB-LIKE PULSAR WIND NEBULA G54.1+0.3 AND THE SEARCH FOR ITS SUPERNOVA REMNANT SHELL
supernova remnants molecules radio continuum
2014/12/23
We discovered a large-scale shell G53.9+0.2 around the Crab-like pulsar wind nebula (PWN) G54.1+0.3 with 1420 MHz continuum Very Large Array observations. This is confirmed by a new infrared (IR) imag...
The evolution of globular clusters: Analysis of external effects and determination of progenitor populations
Globular cluster evolution Evolution The Milky Way. Base elliptical galaxies galaxy
2014/12/9
We include external effects in the Fokker-Planck scheme for studying globular cluster evolution. We use this method to study cluster evolution under the combined influence of relaxation, tidal heating...
Determination of Acceleration from 3D Reconstruction of Coronal Mass Ejections Observed by STEREO
Determination Acceleration Reconstruction Ejections Observed
2011/9/30
We employ a three-dimensional (3D) reconstruction technique, for the first time to study the kinematics of six coronal mass ejections (CMEs), using images obtained from the COR1 and COR2 coronagraphs ...
Determination of the Mean HI Absorption of the Intergalactic Medium
Quasar absorption lines—galaxies intergalactic medium
2010/9/15
In recent years, the Lyman-α forest in quasar spectra has been used, together with N-body simulations, to determine the underlying matter distribution in the intergalactic medium (IGM). One of the key...

SIMULATIONS OF THE BROAD LINE REGION OF NGC 5548 WITH CLOUDY CODE：TEMPERATURE DETERMINATION
Galaxies active-Galaxies individual NGC 5548-Galaxies Seyfert-Line formation-Plasmas
2009/2/10
In this paper an analysis of the physical properties of the Broad
Line Region (BLR) of the active galaxy NGC 5548 is presented. Using the photoion-
ization code CLOUDY and the measurements of Peters...
