Probing dark energy beyond $z=2$ with CODEX
Probing dark energy CODEX cosmological redshift
2012/2/21
Precision measurements of nature's fundamental couplings and a first measurement of the cosmological redshift drift are two of the key targets for future high-resolution ultra-stable spectrographs suc...
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.
Probing the course of cosmic expansion with a combination of observational data
cosmic expansion combination of observational data
2010/11/16
We study the cosmic expansion history by reconstructing the deceleration parameter q(z)
from the SDSS-II type Ia supernova sample (SNIa) with two different light curve fits (MLCS2k2
and SALT-II), th...
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...
Near-IR Molecular Hydrogen Emission of Protostars: Probing Circumstellar Environments
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/28
We present new observations of near-infrared molecular hydrogen (H2) line emission in a sample of 18 Class I and flat-spectrum low mass protostars, primarily in the Tau- Aur and {\rho} Oph dark clouds...
