The gas metallicity gradient and the star formation activity of disc galaxies
Patricia B. Tissera, Susana E. Pedrosa, Emanuel Sillero +1
We study oxygen abundance profiles of the gaseous disc components in simulated galaxies in a hierarchical universe. We analyse the disc metallicity gradients in relation to the ste…
PopIII-star siblings in IZw18 and WRs in metal-poor galaxies unveiled from integral field spectroscopy
Carolina Kehrig, Jose M. Vilchez, Enrique Perez-Montero +5
Here we highlight our recent results from the IFS study of Mrk178, the closest metal-poor WR galaxy, and of IZw18, the most metal-poor star-forming galaxy known in the local Univer…
Localized starbursts in dwarf galaxies produced by impact of low metallicity cosmic gas clouds
J. Sanchez Almeida, B. G. Elmegreen, C. Munoz-Tunon +7
Models of galaxy formation predict that gas accretion from the cosmic web is a primary driver of star formation over cosmic history. Except in very dense environments where galaxy…
The Spanish Square Kilometre Array White Book
J. A. Acosta-Pulido, I. Agudo, A. Alberdi +116
The Square Kilometre Array (SKA) is called to revolutionise essentially all areas of Astrophysics. With a collecting area of about a square kilometre, the SKA will be a transformat…
Tracing kinematic (mis)alignments in CALIFA merging galaxies: Stellar and ionized gas kinematic orientations at every merger stage
J. K. Barrera-Ballesteros, B. García-Lorenzo, J. Falcón-Barroso +27
We present spatially resolved stellar and/or ionized gas kinematic properties for a sample of 103 interacting galaxies, tracing all merger stages: close companions, pairs with morp…
Fossil group origins V. The dependence of the luminosity function on the magnitude gap
S. Zarattini, J. A. L Aguerri, R. Sanchez-Janssen +11
In nature we observe galaxy aggregations that span a wide range of magnitude gaps between the two first-ranked galaxies of a system (). There are systems with gaps close t…
