XMM-Newton observation of MACHO 104.20906.960: a dwarf nova candidate with a 2 h period
A. A. Nucita, S. Carpano, F. De Paolis +3
The binaries known as cataclysmic variables are particular binary systems in which the primary star (a white dwarf) accretes material from a secondary via Roche-lobe mechanism. Usu…
The Seyfert 1 Galaxy Mrk 335 at a very low flux state: mapping the soft X-ray photoionised gas
A. L. Longinotti, A. Nucita, M. Santos-Lleo +1
This paper reports on an XMM-Newton observation of the Seyfert 1 Galaxy Mrk 335 performed as a Target of Opportunity when the source was in an unusually low flux state. The low lev…
XMMU J134736.6+173403: an eclipsing LMXB in quiescence or a peculiar AGN?
S. Carpano, B. Altieri, A. R. King +2
Aims. We report the discovery of a peculiar object observed serendipitously with XMM-Newton. We present its timing and spectral properties and investigate its optical counterpart.…
XMM observation of 1RXS J180431.1-273932: a new M-type X-ray binary with a 494 s-pulse period neutron star?
A. A. Nucita, S. Carpano, M. Guainazzi
Low-mass X-ray binaries are binary systems composed of a compact object and a low-mass star. Recently, a new class of these systems, known as symbiotic -ray binaries (with a neu…
Apoastron Shift Constraints on Dark Matter Distribution at the Galactic Center
A. F. Zakharov, A. A. Nucita, F. De Paolis +1
The existence of dark matter (DM) at scales of few pc down to pc around the centers of galaxies and in particular in the Galactic Center region has been considered…
Emission of gravitational waves from binary systems in the galactic center and diffraction by star clusters
P. Longo, G. Congedo, A. Nucita +2
Binary systems of compact objects are strong emitters of gravitational waves whose amplitude depends on the binary orbital parameters as the component mass, the orbital semi-major…
