Probing the faint end of the quasar luminosity function at z ~ 4 in the COSMOS field
cosmology observations — quasars general — surveys
2010/11/12
We searched for quasars that are 3 mag fainter than the SDSS quasars in the redshift range 3.7 . z . 4.7 in the COSMOS field to constrain the faint end of the quasar luminosity function.
The First Ultra-Cool Brown Dwarf Discovered by the Wide-field Infrared Survey Explorer
(stars:) brown dwarfs (Galaxy:)solar neighborhood infrared
2010/11/12
We report the discovery of the first new ultra-cool brown dwarf found with the Wide-field Infrared Survey Explorer (WISE). The object’s preliminary designation is WISEPC J045853.90+643451.
A deep wide-field sub-mm survey of the Carina Nebula complex
A deep wide-field sub-mm Carina Nebula complex
2010/11/15
Context. The Great Nebula in Carina is one of the most massive (M∗,total >∼25 000 M⊙) star-forming complexes in our Galaxy and contains several stars with (initial) masses exceeding ≈ 100 ...
A Wide Field Survey of Satellite Galaxies around the Spiral Galaxy M106
galaxies；individual (M106) —galaxies；morphology and pho-tometry — galaxies；dwarf galaxies
2010/11/15
We present a wide field survey of satellite galaxies in M106 (NGC 4258)covering a 1.7◦ × 2◦ field around M106 using Canada-France-Hawaii Tele-scope/MegaCam. We find 16 satellite galaxy can...
Wide-field VLBA Observations of the Chandra Deep Field South
Techniques interferometric Galaxies: active Galaxies evolution
2010/11/15
Context. Wide-field surveys are a commonly-used method for studying thousands of objects simultaneously, to investigate, e.g., the joint evolution of star-forming galaxies and active galactic nuclei. ...
Magnetic field structure in a high-mass outflow/disk system
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/7
To characterize the magnetic field structure of the outflow and core region within a prototypical high-mass star-forming region, we analyzed polarized CO(3-2) - for the first time observed with the Su...
Faraday rotation: effect of magnetic field reversals
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
The standard formula for the rotation measure, RM, which determines the position angle, $\psi={\rm RM}\lambda^2$, due to Faraday rotation, includes contributions only from the portions of the ray path...
External field effect of modified Newtonian dynamics in the Solar system
Cosmology and Extragalactic Astrophysics (astro-ph.CO) General Relativity and Quantum Cosmology (gr-qc)
2010/12/27
The Modified Newtonian Dynamics (MOND) has been formulated as a modification of the Poisson equation for the Newtonian gravitational field.
HerMES : SPIRE detection of high redshift massive compact galaxies in GOODS-N field
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We have analysed the rest-frame far infrared (FIR) properties of a sample of massive (Mstar > 10^11Msun) galaxies at 2 in the GOODS (Great Observatories Origins Deep Survey) North field using the ...
Extragalactic radio surveys are an increasingly popular method to investigate the evolution
of star-forming and active galaxies. However, their resolution is of the order of arcseconds and hence not ...
