Optimal filter systems for photometric redshift estimation
N. Benitez, M. Moles, J. A. L. Aguerri +18
In the next years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narro…
Seyfert's Sextet: A Slowly Dissolving Stephan's Quintet?
A. Durbala, A. del Olmo, M. S. Yun +7
We present a multiwavelength study of the highly evolved compact galaxy group known as Seyfert's Sextet (HCG79: SS). We interpret SS as a 2-3 Gyr more evolved analog of Stephan's Q…
Nuclear Activity in UZC Compact Groups of Galaxies
M. A. Martinez, A. del Olmo, P. Focardi +1
We analyse the level of nuclear activity in galaxies belonging to UZC-CGs. Spectra are available for 868 galaxies (90% of the whole catalog); 67 % of them show nuclear activity (AG…
Detection of optical linear polarization in the SN2006aj/XRF060218 non-spherical expansion
J. Gorosabel, V. Larionov, A. J. Castro-Tirado +10
We have performed optical polarimetric observations of the SN2006aj associated to the X-ray flash (XRF) of February 18, 2006, XRF060218 that provide information on its expansion ge…
