ar X iv : a st ro - p h / 02 02 07 5 v 1 4 F eb 2 00 2 H α rotation curves : the soft core question

We present good resolution Hα rotation curves of 6 galaxies: late-type dwarf and low surface brightness galaxies (LSB) for which accurate HI rotation curves are available from the literature. Observations are carried out at Telescopio Nazionale Galileo (TNG). For LSB F583-1 an innovative dispersing element was used, the Volume Phase Holographic (VPH) with a dispersion of about 0.35 Åpxl. From o...

The pulsar magnetosphere contains a strongly magnetized, relativistic plasma. We need to understand the physics of that plasma if we want to connect the data to the models. Our group in Socorro is mixing theory and observations in order to study the radio-loud pulsar plasma. In this paper we report on several aspects of our current work.
