Powerful High-Velocity Dispersion Molecular Hydrogen Associated with an Intergalactic Shock Wave in Stephan's Quintet
interactions intergalactic medium
2014/12/23
We present the discovery of strong mid-infrared emission lines of molecular hydrogen of apparently high-velocity dispersion (~870 km s-1) originating from a group-wide shock wave in Stephan's Quintet....
Multiwavelength study of parsec scale outflows associated with low mass young stellar objects
Arrow flow Low quality of the original star formation Optical observation star
2014/12/9
A multi-wavelength, multi-telescope observational study of recently discovered parsec-scale Herbig-Haro flows associated with the earliest stages of low mass protostellar formation is presented. Impro...
Identification of Ambient Molecular Clouds Associated with Galactic Supernova Remnant IC443
Ambient Molecular Clouds Associated Galactic Supernova Remnant IC443
2012/2/23
The Galactic supernova remnant (SNR) IC443 is one of the most studied core-collapse SNRs for its interaction with molecular clouds. However, the ambient molecular clouds with which IC443 is interactin...
Subsurface flows associated with rotating sunspots
Sun helioseismology, Sun interior, (Sun) sunspots
2011/10/19
In this paper, we compare components of the horizontal flow below the solar surface in and around regions consisting of rotating and non-rotating sunspots. Our analysis suggests that there is a signif...
Changes in Sea-Level Pressure over South Korea Associated with High-Speed Solar Wind Events
solar-terrestrial weather sea-level pressure solar wind
2011/9/30
We explore a possibility that the daily sea-level pressure (SLP) over South Korea responds to the high-speed solar wind event. This is of interest in two aspects: First, if there is a statistical asso...
Multi-Wavelength Observations of a Flux Rope Failed in the Eruption and Associated M-Class Flare from NOAA AR 11045
coronal loops magnetic eld ux rope magnetic reconnection
2011/9/27
We present the multi-wavelength observations of a flux rope that was trying to erupt from NOAA AR 11045 and the associated M-class solar flare on 12 February 2010 using space and ground based observat...
Inflation with improved D3-brane potential and the fine tunings associated with the model
improved D3-brane potential the fine tunings associated
2011/1/13
We investigate brane-antibrane inflation in a warped deformed conifold background that includes contributions to the potential arising from imaginary anti-self-dual (IASD) fluxes including the term wi...
Structure in phase space associated with spiral and bar density waves in an N-body galactic disk
bar density waves N-body galactic disk
2011/1/11
An N-body simulation of a Galactic disk is used to study the stellar phase space distribution or velocity distributions in different local neighborhoods. Pattern speeds identified in Fourier spectrogr...
A search for gravitational waves associated with the August 2006 timing glitch of the Vela pulsar
gravitational waves glitch of the Vela pulsar
2010/11/16
The physical mechanisms responsible for pulsar timing glitches are thought to excite quasi-normal mode oscillations in their parent neutron star that couple to gravitational wave emission. In August 2...
On the Implications of Late Internal Dissipation for Shallow-Decay Afterglow Emission and Associated High-Energy Gamma-Ray Signals
gamma-rays burst general— gamma rays theory— radiation mechanisms non-thermal
2010/11/10
The origin of the shallow-decay emission during early X-ray afterglows has been an open issue since the launch of the Swift satellite. One of the appealing models is the late internal dissipation mode...
Is Palomar 1 really associated with the Canis Major overdensity?
Palomar Canis Major overdensity
2010/11/16
t has recently been suggested that the peculiar cluster Pal 1 is associated to the Canis Major dwarf galaxy, which existence is still at the center of a debate. Our rst measurement of the cluster's c...
Photospheric flux cancellation and associated flux rope formation and eruption
Sun photosphere – Sun coronal mass ejections – Sun magnetic fields
2010/11/11
Aims. We study an evolving bipolar active region that exhibits flux cancellation at the internal polarity inversion line, the formation of a soft X-ray sigmoid along the inversion line and a coronal m...
The similarity of observed X-ray coronae associated with L* disc and elliptical galaxies
galaxies:formation – galaxies haloes – galaxies cooling flows – galaxies intergalactic intergalactic
2010/11/12
The existence of hot, X-ray luminous gaseous coronae surrounding present day L? galaxies
is a generic prediction of galaxy formation theory in the cold dark matter cosmogony.
While extended X-ray em...
