Toward a galaxian luminosity-metallicity relation spanning ten magnitudes
Ivo Saviane, Fabio Bresolin, John Salzer
We describe the two projects by which we are assembling a database of near-IR luminosities and direct oxygen abundances for both high- and low-mass star-forming galaxies in the nea…

X-ray/TeV-gamma-ray observations of several strong flares of Mkn 501 during 1997 and implications
H. Krawczynski, P. S. Coppi, T. Maccarone +1
During more than 6 months in 1997, the BL Lac object Mkn 501 was in an exceptionally bright state, both in the X-ray band and in the Very High Energy (VHE) band. In this paper we p…
