Azimuthal dependence of the density distribution in outer galactic discs accreting intergalactic flows
M. Lopez-Corredoira, J. Betancort-Rijo
AIMS. The amplitude and scaleheight of the Galactic gas disc density are not axisymmetric against expectations in a self-gravity axisymmetric disc. However, this lopsidedness can b…
The long Galactic bar as seen by UKIDSS Galactic Plane Survey
A. Cabrera-Lavers, C. Gonzalez-Fernandez, F. Garzon +2
Over the last decade there have been a series of results supporting the hypothesis of the existence of a long thin bar in the Milky Way with a half-length of 4.5 kpc and a position…
Estimation of galactic model parameters in high latitudes with SDSS
S. Bilir, A. Cabrera-Lavers, S. Karaali +3
We estimated the Galactic model parameters for a set of 36 high-latitude fields included in the currently available Data Release 5 (DR 5) of the Sloan Digital Sky Survey ({\em SDSS…
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…
Estimation of Galactic model parameters in high latitudes with 2MASS
A. Cabrera-Lavers, S. Bilir, S. Ak +2
In this paper, we try to find any dependence of the Galactic structural parameters with the Galactic longitude for either the thin disc or the thick disc of the Milky Way, that wou…
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…
