The Average Age Map of the Galactic Bulge
Jialu Nie, Martín López-Corredoira, Chao Liu +2
The Galactic Bulge, as the center of the Galaxy, is the closest laboratory for studying galaxy formation and evolution. However, its study faces significant challenges due to heavy…
Alcock-Paczynski cosmological test
Martin Lopez-Corredoira
In order to test the expansion of the universe and its geometry, we carry out an Alcock & Paczynski cosmological test, that is, an evaluation of the ratio of observed angular size…
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…
Absence of significant cross-correlation between WMAP and SDSS
M. Lopez-Corredoira, F. Sylos Labini, J. Betancort-Rijo
AIMS. Several authors have claimed to detect a significant cross-correlation between microwave WMAP anisotropies and the SDSS galaxy distribution. We repeat these analyses to deter…
Pending problems in QSOs
Martin Lopez-Corredoira
Quasars (Quasi Stellar Objects, abbreviated as QSOs) are still nowadays, close to half a century after their discovery, objects which are not completel y understood. In this brief…
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…
