We have observed six clouds along the line of sight toward W49A using the Submillimeter Wave Astronomy Satellite and several ground-based observatories. The ortho-H2O 110 → 101 and OH (1665 and 1667 M...
Redshift-Space Enhancement of Line-of-Sight Baryon Acoustic Oscillations in the SDSS Main-Galaxy Sample
cosmology large-scale structure of Universe - methods data analysis
2010/11/15
We show that redshift-space distortions of galaxy correlations have a strong e ect on correlation functions with distinct, localized features, like the signature of the Baryon Acoustic Oscillations (B...
Cosmography with cluster strong lenses: the influence of substructure and line-of-sight halos
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/22
We explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation. The cores of massive clusters often contain several multiply ima...
MEASUREMENT OF THE LICK INDICES IN EARLY-TYPE GALAXIES: LINE-OF-SIGHT VELOCITY DISTRIBUTION CORRECTIONS FOR IC 1459
Line: profiles Methods: data analysis Galaxies: elliptical and lenticular, cD Galaxies: kinematics and dynamics Galaxies: individual (IC 1459)
2010/10/29
In this paper we analyse the measurements of the absorption line-strength Lick indices in the early-type galaxy IC 1459. We use the long-slit spectra of the elliptical galaxy IC 1459 from which its ki...
Comparison of high-latitude line-of-sight ozone column density with derived ozone fields and the effects of horizontal inhomogeneity
high-latitude line-of-sight ozone column density derived ozone fields effects of horizontal inhomogeneity
2009/1/8
Extensive ozone measurements were made during the second SAGE III Ozone Loss and Validation Experiment (SOLVE II). We compare high-latitude line-of-sight (LOS) slant column ozone measurements from the...
Microwave Signal Attenuation in Harmattan Weather Along Calabar-Akampkpa Line-of-Sight Link
Harmattan Radio signal Fog attenuation Statistics of fade Calabar
2010/4/13
Line-of-sight (LOS) attenuation at 6.44GHz was measured at Calabar (4° 58' N, 8° 17' E) for ten months (Aug '93-May '94) using the Nigerian Telecommunications radio signal. The measurement was made wi...
