Astrometric microlensing
A. A. Nucita, F. De Paolis, G. Ingrosso +2
Astrometric microlensing will offer in the next future a new channel for investigating the nature of both lenses and sources involved in a gravitational microlensing event. The eff…
A catalogue sample of low mass galaxies observed in X-rays with central candidate black holes
A. A. Nucita, L. Manni, F. De Paolis +2
We present a sample of -ray selected candidate black holes in 51 low mass galaxies with {and mass up to M} obtained by cross-correlating the NAS…
Parallax and orbital effects in astrometric microlensing with binary sources
A. A. Nucita, F. De Paolis, G. Ingrosso +2
In gravitational microlensing, binary systems may act as lenses or sources. Identifying lens binarity is generally easy especially in events characterized by caustic crossing since…
The Scales of Gravitational Lensing
Francesco De Paolis, Mosè Giordano, Gabriele Ingrosso +3
After exactly a century since the formulation of the general theory of relativity, the phenomenon of gravitational lensing is still an extremely powerful method for investigating i…
First X-ray dectection of the young variable V1180 Cas
S. Antoniucci, A. A. Nucita, T. Giannini +8
V1180 Cas is a young variable that has shown strong photometric fluctuations (Delta_I~6mag) in the recent past, which have been attributed to events of enhanced accretion. The sour…
XMM-Newton observation of a sample of four close dSph galaxies
L. Manni, A. A. Nucita, F. De Paolis +2
We present the results of the analysis of deep archival \sat\ observations towards the dwarf spheroidal galaxies Draco, Leo I, Ursa Major II and Ursa Minor in the Milky Way neighbo…
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…
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…
An XMM-Newton search for X-ray sources in the Fornax dwarf galaxy
A. A. Nucita, L. Manni, F. De Paolis +2
We report the results of a deep archive XMM-Newton observation of the Fornax spheroidal galaxy that we analyzed with the aim of fully characterizing the X-ray source population (in…
The Trace Anomaly and the Gravitational Coupling of an Anomalous U(1)
Roberta Armillis, Claudio Coriano, Luigi Delle Rose +1
We extend a previous computation of the TJJ correlator, involving the energy-momentum tensor of an abelian gauge theory and two vector currents, to the case of mixed axial-vector/v…
