Measuring Polarization in microlensing events
G. Ingrosso, S. Calchi Novati, F. De Paolis +3
We re-consider the polarization of the star light that may arise during microlensing events due to the high gradient of magnification across the atmosphere of the source star, by e…
The puzzling source IGR J17361-4441 in NGC 6388: a possible planetary tidal disruption event
Melania Del Santo, Achille A. Nucita, Giuseppe Lodato +5
On 2011 August 11, INTEGRAL discovered the hard X-ray source IGR J17361-4441 near the centre of the globular cluster NGC 6388. Follow up observations with Chandra showed the positi…
XMM-Newton and Swift observations of WZ Sge: spectral and timing analysis
A. A. Nucita, E. Kuulkers, F. De Paolis +3
WZ Sagittae is the prototype object of a subclass of dwarf novae, with rare and long (super)outbursts, in which a white dwarf primary accretes matter from a low mass companion. Hig…
Planck's confirmation of the M31 disk and halo rotation
F. De Paolis, V. G. Gurzadyan, A. A. Nucita +8
Planck's data acquired during the first 15.4 months of observations towards both the disk and halo of the M31 galaxy are analyzed. We confirm the existence of a temperature asymmet…
Signatures of rotating binaries in micro-lensing experiments
A. A. Nucita, M. Giordano, F. De Paolis +1
Gravitational microlensing offers a powerful method with which to probe a variety of binary-lens systems, as the binarity of the lens introduces deviations from the typical (single…
M31 Pixel Lensing PLAN Campaign: MACHO Lensing and Self Lensing Signals
S. Calchi Novati, V. Bozza, I. Bruni +14
We present the final analysis of the observational campaign carried out by the PLAN (Pixel Lensing Andromeda) collaboration to detect a dark matter signal in form of MACHOs through…
The puzzling symbiotic X-ray system 4U1700+24
A. A. Nucita, S. Stefanelli, F. De Paolis +4
Symbiotic X-ray binaries form a subclass of low-mass X-ray binary systems consisting of a neutron star accreting material from a red giant donor star via stellar wind or Roche lobe…
