First results from the ALHAMBRA-Survey
A. Fernandez-Soto, J. A. L. Aguerri, E. J. Alfaro +17
We present the first results from the ALHAMBRA survey. ALHAMBRA will cover a relatively wide area (4 square degrees) using a purposely-designed set of 20 medium-band filters, down…
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…
Low Luminosity Activity in Hickson Compact Groups
M. A. Martinez, A. del Olmo, J. Perea +1
With the aim of studying the influence of environment on the nuclear activity of galaxies, we have selected a well defined sample of 65 Compact Groups of galaxies with concordant r…
The ALHAMBRA Survey: For a systematic Study of Cosmic Evolution
Mariano Moles, Emilio Alfaro, Narciso Benítez +16
ALHAMBRA is a project to gather data to sample a fraction of the Universe with enough precision to follow the evolution of its content and properties with z, a kind of Cosmic Tomog…
Ripples and tails in the compact group of galaxies Hickson 54
L. Verdes-Montenegro, A. Del Olmo, J. I. Iglesias-Páramo +4
HCG 54 has been classified as a compact galaxy group by Hickson, but its nature is uncertain because of its unusual properties. We present here a study of HCG~54 based on deep opti…
Where is the Neutral Atomic Gas in Hickson Groups?
L. Verdes-Montenegro, M. S. Yun, B. A. Williams +3
We have analyzed the total HI contents of 72 Hickson compact groups of galaxies (HCGs) and the detailed spatial distributions and kinematics of HI within a subset of 16 groups usin…
