We explore the stability of tidal streams to perturbations, motivated by recent claims that the clumpy structure of the stellar streams surrounding the globular cluster Palomar 5 are the result of gravitational instability. We calculate the Jeans length of tidal streams by treating them as a thin expanding cylinder of collisionless matter. We also find a general relation between the density and...

ABSTRACT Bars play an important role in mixing material the inner regions of galaxies and stimulating radial migration. Previous observations have found evidence for impact a bar on metallicity gradients but effect is still inconclusive. We use TYPHOON/PrISM survey to investigate along beyond region across entire star-forming disc five nearby galaxies. Using emission line diagrams identify spax...

Purpose. Transitional cell carcinoma (TCC) affecting the graft after renal transplantation is a very infrequent way of presentation of this tumor. Our aim is to present our single institution experience with 2 cases, as well as to perform a review of the literature about this tumor after the transplant. Materials and Methods. TCC of the graft developed in 2 of 1365 patients from 1977 to 2010, b...
