Velocity catalog of A545 galaxies (Barrena+, 2011)
Multi-object spectroscopic observations of A545 were carried out at the TNG telescope in October 2009. We used DOLORES/MOS with the LR-B Grism 1, yielding a...
Velocity Dispersions and Stellar Populations of the Most Compact and Massive Early-Type Galaxies at Redshift ~1
We present Gran-Telescopio-Canarias/OSIRIS optical spectra of 4 of the most compact and massive early-type galaxies in the Groth Strip Survey at redshift z 1...
Velocity fields associated with the magnetic component of solar faculae
Theoretical models are developed to account for the asymmetries observed by Stenflo et al. (1984) in the Stokes V profiles of solar faculae. The approximate...
Line-of-sight velocity fields in an irregular sunspot (NOAA 8990) have been determined from Stokes-I spectra of the line Fe I 630.15 nm, obtained with the La...

Velocity signal produced by the passage of active regions compared with observations
A calibrated numerical simulation of seasons for which there are observations of the passage of active regions across the visible disk of the sun, generating a...
