BeppoSAX serendipitous discovery of the X-ray pulsar SAX J1802.7-2017

2003

We report on the serendipitous discovery of a new X-ray source, SAX J1802.7-2017, ~22' away from the bright X-ray source GX 9+1, during a BeppoSAX observation of the latter source on 2001 September 16-20. SAX J1802.7-2017 remained undetected in the first 50 ks of observation; the source count rate in the following ~300 ks ranged between 0.04 c/s and 0.28 c/s, corresponding to an averaged 0.1-10 keV flux of 3.6 10^{-11} ergs cm^{-2} s^{-1}. We performed a timing analysis and found that SAX J1802.7-2017 has a pulse period of 139.612 s, a projected semimajor axis of a_x sin i ~ 70 lt-s, an orbital period of ~4.6 days, and a mass function f(M) ~ 17 Msun. The new source is thus an accreting X-ra…

CeSOX: An experimental test of the sterile neutrino hypothesis with Borexino

2017

International audience; The third phase of the Borexino experiment that’s referred to as SOX is devoted to test the hypothesis of the existence of one (or more) sterile neutrinos at a short baseline (~5–10m). The experimental measurement will be made with artificial sources namely with a 144Ce–144Pr antineutrino source at the first stage (CeSOX) and possibly with a 51Cr neutrino source at the second one. The fixed 144Ce–144Pr sample will be placed beneath the detector in a special pit and the initial activity will be about 100 – 150 kCi. The start of data taking is scheduled for April 2018. The article gives a short description of the preparation for the first stage and shows the expected s…

Breve storia di una riforma incompiuta

2018

L'articolo analizza in chiave storico-critica l'evoluzione del rapporto di lavoro alle dipendenze delle pubbliche amministrazioni sulla scorta delle riforme "Brunetta" (d.lgs. 150/2009) e "Madia" (d.lgs. 74/2017 e d.lgs. 75/2017), soffermandosi sulla recente giurisprudenza della Corte costituzionale (sent. 251/2016) e sulle criticità sottese ai decreti attuativi della delega del 2017.
