Dust in clusters: separating the contribution of galaxies and intracluster media
C. M. Gutierrez, M. Lopez-Corredoira
We have analized a sample of 327 clusters of galaxies spanning the range 0.06-0.70 in redshift. Strong constraints on their mean intracluster emission by dust have been obtained us…
The most distant compact groups
C. M. Gutierrez
We present photometric and spectroscopic observations of the members of three previously cataloged compact group (CG) candidates at redshifts z>0.3. These confirm spectroscopic red…
The value of the fine structure constant over cosmological times
C. M. Gutierrez, M. Lopez-Corredoira
The optical spectra of objects classified as QSOs in the SDSS DR6 are analyzed with the aim of determining the value of the fine structure constant in the past and then check for p…
The spatial distribution of galaxies within the CMB cold spot in the Corona Borealis supercluster
C. P. Padilla-Torres, C. M. Gutierrez, R. Rebolo +2
We study the spatial distribution and colours of galaxies within the region covered by the cold spot in the cosmic microwave background (CMB) recently detected by the Very Small Ar…
Analysis of possible anomalies in the QSO distribution of the Flesch & Hardcastle catalogue
M. Lopez-Corredoira, C. M. Gutierrez, V. Mohan +2
AIMS. A recent catalogue by Flesch & Hardcastle presents two major anomalies in the spatial distribution of QSO candidates: i/ an apparent excess of such objects near bright galaxi…
First tentative detection of anisotropy in the QSO distribution around nearby edge-on spiral galaxies
M. Lopez-Corredoira, C. M. Gutierrez
AIMS. To check whether the polar angle distribution of QSOs around nearby spiral galaxies is isotropic or not. METHODS. A statistical analysis of the polar angle distribution of la…
