Star-forming galaxies in SDSS: signs of metallicity evolution
M. A. Lara-Lopez, J. Cepa, A. Bongiovanni +5
Evolution of galaxies through cosmic time has been widely studied at high redshift, but there are a few studies in this field at lower redshifts. However, low-redshifts studies wil…
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…
MAGIC upper limits to the VHE gamma-ray flux of 3C454.3 in high emission state
H. Anderhub, S. Vercellone, I. Donnarumma +2
We report upper limits to the very high energy flux (E>100 GeV) of the flat spectrum radio quasar 3C454.3 (z=0.859) derived by the Cherenkov telescope MAGIC during the high states…
The pulsating hot subdwarf Balloon 090100001: results of the 2005 multisite campaign
A. Baran, R. Oreiro, A. Pigulski +28
We present the results of a multisite photometric campaign on the pulsating sdB star Balloon 090100001. The star is one of the two known hybrid hot subdwarfs with both long- and sh…
Discovery of a very high energy gamma-ray signal from the 3C 66A/B region
MAGIC Collaboration, E. Aliu
The MAGIC telescope observed the region around the distant blazar 3C 66A for 54.2 h in 2007 August-December. The observations resulted in the discovery of a gamma-ray source at ene…
Convectively driven vortex flows in the Sun
J. A. Bonet, I. Marquez, J. Sanchez Almeida +2
We have discovered small whirlpools in the Sun, with a size similar to the terrestrial hurricanes (<~0.5 Mm). The theory of solar convection predicts them, but they had remained el…
