QSO H 1413 + 1143 : Modeling the Lens
We investigate gravitational lens models for the quadruply-lensed Cloverleaf BAL QSO H1413+1143 based on the HST WFPC/WFPC2 astrometric and photometric data of the system by Turnshek et al. and the HST NICMOS-2 data by Falco et al. The accurate image positions and the dust-extinction-corrected relative amplifications, along with a possible detection of the lensing galaxy in the infrared, permit...
متن کاملMolecular absorption lines at high redshift : PKS 1413 + 135 ( z = 0 . 247 )
A detailed study of the absorbing molecular clouds towards the radio source PKS1413+135, at a red-shift z=0.247, is reported. Physical conditions (density, temperature, filling factors) are derived for the molecular gas, in the frame work of two models: a homogeneous multicomponent model with equal filling factors, and a two–phase medium consisting of dense clumps embedded in a more diffuse com...
متن کاملClusters of Galaxies: Multifrequency Observations versus Theories
Clusters of galaxies are large gravitationally bound systems which consist of several observable components: hundreds of galaxies, hot gas between the galaxies and sometimes relativistic particles. These components are emitting in different wavelengths from radio to X-rays. We show that the combination of observations at different frequencies and also theoretical models is giving now a comprehe...
متن کاملChandra Observations of Qso 2237 + 0305
We present the observations of the gravitationally lensed system QSO 2237+0305 (Einstein Cross) performed with the Advanced CCD Imaging Spectrometer (ACIS) onboard the Chandra X-ray Observatory on 2000 September 6, and on 2001 December 8 for 30.3 ks and 9.5 ks, respectively. Imaging analysis resolves the four X-ray images of the Einstein Cross. A possible fifth image is detected; however, the p...
متن کاملVLA multifrequency observations of RS CVn binaries
We present multiepoch Very Large Array (VLA) observations at 1.4 GHz, 4.9 GHz, 8.5 GHz and 14.9 GHz for a sample of eight RS CVn binary systems. Circular polarization measurements of these systems are also reported. Most of the fluxes observed are consistent with incoherent emission from mildly relativistic electrons. Several systems show an increase of the degree of circular polarization with ...
