TL;DR: In this article, the authors reported the detection by the Beppo-SAX satellite of an X-ray "afterglow" associated with the γ-ray burst of 28 February 1997 (GRB970228; ref.

TL;DR: In this paper, the authors studied the properties of massive, galactic-scale outflows of molecular gas and investigated their impact on galaxy evolution, finding that the presence of an active galactic nucleus (AGN) can boost the outflow rate by a large factor, which is found to increase with the L-AGN/L-bol ratio.

TL;DR: The first afterglow of a gamma-ray burst was detected and quickly positioned by the Beppo-SAX satellite on 1997 February 28 (GRB970228) as discussed by the authors.

TL;DR: In this paper, the authors present the results of position sensitive proportional counter (PSPC) observations of 10 quasars with a redshift z less than or = 0.2 keV and a column density N(sup Gal sub H I) less than 1.9 x 10(exp 20)/sq cm.

TL;DR: In this article, the authors used the IRAM PdB Interferometer to observe the CO(1-0) transition in the closest quasar known, and they detected broad wings of the CO line, with velocities of up to 750 km/s-1 and spatially resolved on the kpc scale.
