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....
The intrinsic dispersion of the Faber-Jackson relation for early-type galaxies as function of the mass and redshift
Galaxies fundamental parameters photometry distances redshifts
2011/10/18
Aims. Recently it has been reported that the intrinsic dispersion at constant magnitude of the structural relations from early-type galaxies is a useful tool to study the universality of these structu...
Real-time, fast radio transient searches with GPU de-dispersion
Real-time fast radio transient searches de-dispersion
2011/10/8
The identification, and subsequent discovery, of fast radio transients through blind-search surveys requires a large amount of processing power, in worst cases scaling as $\mathcal{O}(N^3)$. For this ...
Chemical abundances in the protoplanetary disk LV2 (Orion) - II: High dispersion VLT observations and microjet properties
ISM – abundances HII regions ISM:stars: pre-main-sequence protostars protoplan- etary disks
2011/9/29
Integral field spectroscopy of the LV2 proplyd is presented taken with the VLT/FLAMES Argus array at an angular resolution of 0.31x0.31 arcsec^2 and velocity resolutions down to 2 km/s per pixel. Foll...
Redshift Evolution of the Galaxy Velocity Dispersion Function
Redshift Evolution Galaxy Velocity Dispersion
2011/9/28
We present a study of the evolution of the galaxy Velocity Dispersion Function (VDF) from z=0 to z=1.5 using photometric data from the UKIDSS Ultra Deep Survey (UDS) and Newfirm Medium Band Survey (NM...
HIFLUGCS: Galaxy Cluster Scaling Relations between X-ray Luminosity, Gas Mass, Cluster Radius, and Velocity Dispersion
Cosmology observations — (Cosmology:) dark matter — Galaxies clusters: general — Methods
2010/11/15
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and between cluster radius and velocity dispersion (r500 − )...
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present the first results of an ongoing campaign using the STIS spectrograph on-board the Hubble Space Telescope (HST) whose primary goal is the study of near ultraviolet (UV) spectra of local Type...
An Advanced Atmospheric Dispersion Corrector: The Magellan Visible AO Camera
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2010/12/27
In addition to the BLINC/MIRAC IR science instruments, the Magellan adaptive secondary AO system will have an EEV CCD47 that can be used both for visible AO science and as a wide-field acquisition cam...
CALCULATION OF VELOCITY DISPERSION OF THE NEARBY GALAXIES USING DIFFERENT STELLAR TEMPLATE LIBRARIES
Galaxies: bulges Galaxies: kinematics and dynamics Methods:numerical
2010/10/29
We present the central velocity dispersion measurements of the nearby
galaxies from the Sloan Digital Sky Survey (SDSS). Using the sample from the paper by
Ho et al. 2009, we have selected 23 galaxi...

A NEW APPROACH TO THE ESTIMATION OF THE DISPERSION COMPONENTS
DISPERSION COMPONENTS unknown X iterative algorihm
2009/3/31
A new method to calculate simultaneosly both the unknown X
and the components of the dispersion (results of measurement) is developed. An
improved iterative algorihm is used.
