Luciano Nicastro,J. J. M. in 't Zand,Lorenzo Amati,E. P. Mazets,A. J. Castro-Tirado,J. Gorosabel,Davide Lazzati,Enrico Costa,M. de Pasquale,M. Feroci,F. Frontera,John Heise,Elena Pian,L. Piro,Celia Sanchez-Fernandez,Paul J. Tristram +15 more
TL;DR: In this paper, it was shown that the long duration of the prompt gamma-ray emission is not related to an early onset of afterglow emission, but must be related to prolonged activity of the ''central engine''.

TL;DR: In this paper, the authors proposed an X-ray mission called Xenia to search for decaying superweakly interacting Dark Matter particles (super-WIMP) with a mass in the keV range.

Dale A. Frail,Shrinivas R. Kulkarni,Enrico Costa,F. Frontera,John Heise,M. Feroci,L. Piro,D. Dal Fiume,Luciano Nicastro,Eliana Palazzi,R. Jager +10 more
TL;DR: In this paper, the authors report on a comprehensive radio monitoring program of the bright gamma-ray burster GRB 970111 at a frequency of 1.4 GHz and span a range of postburst timescales between 28 hr and 1 month.
Journal ArticleDOI
Estimate of the impact of background particles on the X-ray Microcalorimeter Spectrometer on IXO
S. Lotti,Emanuele Perinati,Lorenzo Natalucci,L. Piro,L. Piro,Teresa Mineo,L. Colasanti,Claudio Macculi +7 more
TL;DR: In this paper, the authors present the results of a study on the impact of particles of galactic origin on the X-ray Microcalorimeter Spectrometer (XMS) aboard an astronomical satellite flying in an orbit at the second Lagrangian point (L2).
