Disk, merger, or outflow ? Molecular gas kinematics in two powerful obscured QSOs at z>3.4
Galaxies: high-redshift – Submillimeter: ISM – Submillimeter: galaxies – (Galaxies:) quasars: individual
2011/10/8
We report on the detection of bright CO(4-3) line emission in two powerful, obscured quasars discovered in the SWIRE survey, SW022513 and SW022550 at z>3.4. We analyze the line strength and profile to...
Star Clusters in M31: Old Clusters with Bar Kinematics
catalogs – galaxies individual (M31) – galaxies star clusters – globular clusters
2010/11/12
We analyze our accurate kinematical data for the old clusters in the inner regions of M31. These velocities are based on high S/N Hectospec data (Caldwell et al 2010). The data are well suited for ana...
Formation and evolution of dwarf early-type galaxies in the Virgo cluster I. Internal kinematics
Galaxies clusters individual Virgo Galaxies dwarf Galaxies elliptical and lenticular cD Galaxies
2010/11/12
We present new medium resolution kinematic data for a sample of 21 dwarf early-type galaxies (dEs) mainly in the Virgo cluster,obtained with the WHT and INT telescopes at the Roque de los Muchachos Ob...
Complementarity of Kinematics and Geometry in General Relativity Theory
Complementarity of Kinematics Geometry General Relativity Theory
2010/12/20
Relations between kinematics, geometry and law of reference frame motion are considered. We show, that kinematical tensors define geometry up to a space functiona arbitrariness when integrability cond...
Local Stellar Kinematics from RAVE Data: I. Local Standard of Rest
Galaxy kinematics and dynamics solar neighbourhood solar motion local standard of rest stellar content
2010/11/11
We analyze a sample of 82850 stars from the RAVE survey, with well-determined velocities and stellar parameters, to isolate a sample of 18026 high-probability thin-disc dwarfs within 600 pc of the Sun...
Millimeter imaging of MWC 758: probing the disk structure and kinematics
Solar and Stellar Astrophysics (astro-ph.SR) Earth and Planetary Astrophysics (astro-ph.EP)
2011/1/5
We investigate the structure and kinematics of the circumstellar disk around the Herbig Ae star MWC 758 using high resolution observations of the 12CO (3-2) and dust continuum emission at the waveleng...
Kinematics of the Ammonia Disk around the Protostar NGC 1333 IRAS 4A2
Galaxy Astrophysics (astro-ph.GA)
2010/12/28
The NGC 1333 IRAS 4A protobinary was observed in the ammonia (2, 2) and (3, 3) lines with an angular resolution of 0.3 arcsec. The ammonia emission source of IRAS 4A2 is elongated in the direction per...
Solar Wind Drag and the Kinematics of Interplanetary Coronal Mass Ejections
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/23
Coronal mass ejections (CMEs) are large-scale ejections of plasma and magnetic field from the solar corona, which propagate through interplanetary space at velocities of $\sim$100--2500~km~s$^{-1}$.
Two refreshing views of Fluctuation Theorems through Kinematics Elements and Exponential Martingale
Non-equilibrium Markovian Process Fluctuation-Dissipation Theorems Fluctuation Relations Martingale
2010/12/15
In the context of Markovian evolution, we present two original approaches to obtain Generalized Fluctuation-Dissipation Theorems (GFDT), by using the language of stochastic derivatives and by using a ...

2010/10/14
The North Anatolian Fault System (NAFS) is an approximately 2-110-km-wide, 1600-km-long right-lateral intra-continental transform fault boundary between the Anatolian platelet and the Eurasian plate. ...
How to surprise a copepod: Strike kinematics reduce hydrodynamic disturbance and increase stealth of suction-feeding fish
Strike kinematics reduce hydrodynamic disturbance increase stealth suction-feeding fish
2014/4/17
To capture prey with suction, fish must get sufficiently close to their prey to allow the suction flow to overwhelm the prey and draw it into the mouth. Both swimming towards the prey and suction flow...
Inclusive b and b anti-b production with quasi-multi-Regge kinematics at the Tevatron
b anti-b production quasi-multi-Regge kinematics Tevatron
2010/3/16
We consider b-jet hadroproduction in the quasi-multi-Regge-kinematics approach based on the hypothesis of gluon and quark Reggeization in t-channel exchanges at high energies. The preliminary data on ...
