XMM-Newton observation of the persistent Be/NS X-ray binary pulsar RX J0440.9+4431
N. La Palombara, L. Sidoli, P. Esposito +2
Many X-ray accreting pulsars have a soft excess below 10 keV. This feature has been detected also in faint sources and at low luminosity levels, suggesting that it is an ubiquitous…
A time-variable, phase-dependent emission line in the X-ray spectrum of the isolated neutron star RX J0822-4300
A. De Luca, D. Salvetti, A. Sartori +9
RX J0822-4300 is the Central Compact Object associated with the Puppis A supernova remnant. Previous X-ray observations suggested RX J0822-4300 to be a young neutron star with a we…
Matching microlensing events with X-ray sources
N. Sartore, A. Treves
The detection of old neutron stars and black holes in isolation is one of the cornerstones of compact object astrophysics. Microlensing surveys may help on this purpose since the l…
Gas sloshing, cold fronts, Kelvin-Helmholtz instabilities and the merger history of the cluster of galaxies Abell 496
E. Roediger, L. Lovisari, R. Dupke +4
We investigate the origin and nature of the multiple sloshing cold fronts in the core of Abell 496 by direct comparison between observations and dedicated hydrodynamical simulation…
Gamma-ray Activity in the Crab Nebula: The Exceptional Flare of April 2011
R. Buehler, J. D. Scargle, R. D. Blandford +18
The Large Area Telescope on board the Fermi satellite observed a gamma-ray flare in the Crab nebula lasting for approximately nine days in April of 2011. The source, which at optic…
A new super-soft X-ray source in the Small Magellanic Cloud: Discovery of the first Be/white dwarf system in the SMC?
R. Sturm, F. Haberl, W. Pietsch +5
The Small Magellanic Cloud (SMC) hosts a large number of Be/X-ray binaries, however no Be/white dwarf system is known so far, although population synthesis calculations predict tha…
The cosmic-ray and gas content of the Cygnus region as measured in gamma rays by the Fermi Large Area Telescope
the Fermi LAT Collaboration
The Cygnus region hosts a giant molecular-cloud complex which actively forms massive stars. Interactions of cosmic rays with interstellar gas and radiation fields make it shine at…
Supergiant Fast X-ray Transients as transient sources in High Mass X-ray Binaries
L. Sidoli
Supergiant Fast X-ray Transients (SFXTs) represent the most extreme case of X-ray variability in High Mass X-ray Binaries hosting blue supergiant companions. Mainly discovered than…
Fermi Detection of a Luminous Gamma-ray Pulsar in a Globular Cluster
The Fermi LAT Collaboration
We report the Fermi Large Area Telescope detection of gamma-ray (>100 megaelectronvolts) pulsations from pulsar J1823-3021A in the globular cluster NGC 6624 with high significance…
Simultaneous multi-wavelength campaign on PKS 2005-489 in a high state
The H. E. S. S. Collaboration, the Fermi LAT Collaboration, : +345
The high-frequency peaked BL Lac object PKS 2005-489 was the target of a multi-wavelength campaign with simultaneous observations in the TeV gamma-ray (H.E.S.S.), GeV gamma-ray (Fe…
Broadband study of hard X-ray selected absorbed AGN
A. De Rosa, F. Panessa, L. Bassani +6
[Abridged]We report on the broadband X-ray properties of a complete sample of absorbed Seyfert galaxies hard X-ray selected with INTEGRAL. The sample is composed of 33 sources: 15…
Discovery of Nine Gamma-Ray Pulsars in Fermi-LAT Data Using a New Blind Search Method
H. J. Pletsch, L. Guillemot, B. Allen +28
We report the discovery of nine previously unknown gamma-ray pulsars in a blind search of data from the Fermi Large Area Telescope (LAT). The pulsars were found with a novel hierar…
Search for X-ray emission from subdwarf B stars with compact companion candidates
Sandro Mereghetti, Sergio Campana, Paolo Esposito +2
Stellar evolutionary models predict that most of the early type subdwarf stars in close binary systems have white dwarf companions. More massive companions, such as neutron stars o…
Fermi Large Area Telescope Observations of the Supernova Remnant G8.7-0.1
LAT Collaboration
We present a detailed analysis of the GeV gamma-ray emission toward the supernova remnant (SNR) G8.7-0.1 with the Large Area Telescope (LAT) onboard the \emph{Fermi} Gamma-ray Spac…
X-ray Groups of Galaxies at 0.5<z<1 in zCOSMOS: Increased AGN Activities in High Redshift Groups
M. Tanaka, A. Finoguenov, S. J. Lilly +48
We present a photometric and spectroscopic study of galaxies at 0.5<z<1 as a function of environment based on data from the zCOSMOS survey. There is a fair amount of evidence that…
Search for Gamma-ray Emission from X-ray Selected Seyfert Galaxies with Fermi-LAT
LAT Collaboration
We report on a systematic investigation of the gamma-ray properties of 120 hard X-ray-selected Seyfert galaxies classified as `radio-quiet' objects, utilizing the three-year accumu…
Measurement of separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope
The Fermi LAT Collaboration, M. Ackermann, M. Ajello +148
We measured separate cosmic-ray electron and positron spectra with the Fermi Large Area Telescope. Because the instrument does not have an onboard magnet, we distinguish the two sp…
Gamma-Ray and Parsec-Scale Jet Properties of a Complete Sample of Blazars From the MOJAVE Program
