The QUIJOTE TGI instrument is currently being assembled and tested at the IAC in Spain. The TGI is a 31 pixel 26-36 GHz polarimeter array designed to be mounted at the focus of the second QUIJOTE telescope. This follows a first telescope and multi-frequency instrument that have now been observing almost 2 years. The polarimeter design is based on

We report the discovery of the optical counterpart to GRB 980326. Its rapid optical decay can be characterized by a power law with exponent - 2.10+/-0.13 and a constant underlying source at R_{{c}}=25.5+/-0.5 . Its optical colors 2.1 days after the burst imply a spectral slope of - 0.66+/-0.70 . The gamma -ray spectrum as observed with BATSE shows

In this paper we discuss the reason for the widely found discrepancy between Sérsic brightness law fitted along major and minor axes of elliptical galaxies. We show that this difference is a natural consequence of the isophotes eccentricity law. We present a mathematical transformation that allows to obtain the minor axis Sérsic's law from that of

We derive the relative distances to the Virgo, Fornax and Coma clusters of galaxies by applying the D_n-sigma and the Fundamental Plane (FP) relations to the data of the homogeneous samples of early-type galaxies studied by Caon et al., Lucey et al. and Jorgensen et al. The two distance indicators give consistent results, the relative distance

We report the detection of 15 X-ray bursts with RXTE and Swift observations of the peculiar X-ray binary Circinus X-1 (Cir X-1) during its 2010 May X-ray re-brightening. These are the first X-ray bursts observed from the source after the initial discovery by Tennant and collaborators, 25 years ago. By studying their spectral evolution, we firmly

The SW Sextantis stars are nova-like cataclysmic variables (CVs) which exhibit intricate behaviour which is still a matter of debate. For years the common belief has been that these systems were the "outlaws" of the CVs, mainly because of the lack of an overall understanding. We are now realizing that a large percentage (˜ 30%) of all nova-likes in
