Cutoff Flux UL OP ph cm −2 s −1 For regions with no significant detection, the 95% confidence- level photon flux upper limit assuming a PLSuperExpCutoff spec- tral model with

While a clump of extended emission surrounds the pulsar position on the few degree scale, it is at present not possible to associate this flux with known Vela PWN structures (e.g.

We have tested gtbary and gtpphase with giant radio pulses from the Crab pulsar B0531+21 and from the millisecond pulsar B1937+21, recorded at the Nançay radio telescope, X-ray

Its distance (1.7 kpc) is large but not unusual for gamma-ray MSPs. Its ˙ E is high for an MSP, while its lat- itude is low for an MSP but mid-range for young pulsars. In fact it is

In this paper, we present a detailed study of the LAT observations relevant to Laser Interferometer Gravitational-wave Observatory ( LIGO ) event GW150914, which is the fi rst

Then, their variability is characterized as power-law noise with a forward folding method with simulated light curves, taking the sampling of the data, described in Kastendieck et

Combined unabsorbed SED using the gamma-ray fluxes from Fermi-LAT (blue) and AGILE/GRID (red), the XMM-Newton (ma- genta), RXTE (light blue), and INTEGRAL (cyan) average X-ray
