Low-frequency pulse profile variation in PSR B2217+47: evidence for echoes from the interstellar medium
D. Michilli, J. W. T. Hessels, J. Y. Donner +17
We have observed a complex and continuous change in the integrated pulse profile of PSR B2217+47, manifested as additional components trailing the main peak. These transient compon…
AGILE Observations of the Gravitational Wave Source GW170104
F. Verrecchia, M. Tavani, A. Ursi +36
The LIGO/Virgo Collaboration (LVC) detected on 2017 January 4, a significant gravitational-wave (GW) event (now named GW170104). We report in this Letter the main results obtained…
Wide-Band, Low-Frequency Pulse Profiles of 100 Radio Pulsars with LOFAR
M. Pilia, J. W. T. Hessels, B. W. Stappers +84
LOFAR offers the unique capability of observing pulsars across the 10-240 MHz frequency range with a fractional bandwidth of roughly 50%. This spectral range is well-suited for stu…
The peculiar isolated neutron star in the Carina Nebula - Deep XMM-Newton and ESO-VLT observations of 2XMM J104608.7-594306
Adriana Mancini Pires, Christian Motch, Roberto Turolla +5
While fewer in number than the dominant rotation-powered radio pulsar population, peculiar classes of isolated neutron stars (INSs) -- which include magnetars, the ROSAT-discovered…
AGILE detection of Cygnus X-3 γ-ray active states during the period mid-2009/mid-2010
A. Bulgarelli, M. Tavani, A. W. Chen +70
Cygnus X-3 (Cyg X-3) is a well-known microquasar producing variable emission at all wavelengths. Cyg X-3 is a prominent X-ray binary producing relativistic jets, and studying its h…
The brightest gamma-ray flaring blazar in the sky: AGILE and multi-wavelength observations of 3C 454.3 during November 2010
S. Vercellone, E. Striani, V. Vittorini +84
Since 2005, the blazar 3C 454.3 has shown remarkable flaring activity at all frequencies, and during the last four years it has exhibited more than one gamma-ray flare per year, be…
Detection of Gamma-Ray Emission from the Vela Pulsar Wind Nebula with AGILE
A. Pellizzoni, A. Trois, M. Tavani +68
Pulsars are known to power winds of relativistic particles that can produce bright nebulae by interacting with the surrounding medium. These pulsar wind nebulae (PWNe) are observed…
