SNR0540-69 -the Crab twin- revisited: Chandra vs. HST
P. A. Caraveo, R. P. Mignani, A. De Luca +2
High resolution images of the Crab-like SNR SNR0540-69 have been recently obtained by the HRC, on board the Chandra X-ray Observatory, and by the FORS1 instrument, attached to ESO/…
HST as a reliable astrometric tool for pulsar astronomy: the cases of the Vela and Geminga pulsars
A. De Luca, R. P. Mignani, P. A. Caraveo
The quest for the distance of the Vela and Geminga pulsars yielded, so far, a set of four WFPC2 images for each object. The availability of couples of images taken at the same peri…
HST as a powerful astrometric tool for pulsar astronomy
R. P. Mignani, P. A. Caraveo, A. De Luca
Given their intrinsic faintness, isolated neutron stars represent an elusive target for optical astronomy. Up to date, an optical counterpart has been identified only for a very ti…
The HI fine structure of HVC187 near NGC3783, gas in the leading bridge of the Magellanic System
B. P. Wakker, B. D. Savage, T. A. Oosterloo +1
We present an analysis of high-resolution HI data of one of the cores of HVC187 Wakker & van Woerden 1991), HVC287+22+240. Structure is present down to the lowest-measurable scale…
