Where are the massive stars of the bar of NGC 1530 forming?
A. Zurita, I. Perez
Aims: NGC 1530 has one of the strongest bars ever observed and recent star formation sites are distributed across its bar. Our aim is to study the photometric properties of the bar…
Comparison between 2-D and 3-D codes in dynamical simulations of gas flow in barred galaxies
I. Perez
Context: One of the ways to determine the contribution of the dark halo to the gravitational potential of a galaxy is the study of non-circular (streaming) motions and the associat…
New light on the formation and evolution of bars: Trends in the stellar line-strength indices distribution inside the bar region
I. Perez, P. Sanchez-Blazquez, A. Zurita
Aim: The aim is to study the stellar content of the bar region to constrain its formation and evolution. Methods: Line-strength indices in the bar region of a sample of 6 barred ga…
GPS radio sources: new optical observations and an updated master list
A. Labiano, P. D. Barthel, C. P. O'Dea +3
* Aims. Identify optical counterparts, address uncertain identifications and measure previously unknown redshifts of the host galaxies of candidate GPS radio sources, and study the…
The origin of the hot metal-poor gas in NGC1291: Testing the hypothesis of gas dynamics as the cause of the gas heating
I. Perez, K. Freeman
In this paper we test the idea that the low-metallicity hot gas in the centre of NGC 1291 is heated via a dynamical process. In this scenario, the gas from the outer gas-rich ring…
