Modeling X-Ray Emission of a Straight Jet:. PKS 0920-397
Siemiginowska, A.; Birkinshaw, M.; Worrall, D. M. +14 more
We summarize a study of PKS 0920-397 using our 42 ks Chandra observation in conjunction with our ATCA 20GHz image, and HST/ACS F814W and F475W images. We investigate the hypothesis that the jet X-ray emission is due to inverse-Compton (IC) scattering on the cosmic microwave background (CMB) from the same population of relativistic electrons that g…
Counterpart Candidates to the Unidentified Fermi Source 0FGL J1848.6-0138
Combi, J. A.; Luque-Escamilla, P. L.; Martí, J. +3 more
Here we report the finding of a few counterpart candidates inside the 95% confidence error box of the Fermi LAT unidentified gamma-ray source 0FGL J1848.6-0138. Among them, the globular cluster GLIMPSE-C01 is specially remarkable. It offers a conceivable physical scenario for gamma-ray production and if confirmed to be counterpart it would be the …
Pulse Characterization of GRBs with Known Redshift
Kawai, Nobuyuki; Vasquez, Nicolas
Gamma-ray Bursts (GRBs) are one of the most promising tools in the study of cosmology. The luminosity, energy, light curve parameters and spectral measures could yield to the calibration of standard candles in the Universe. Nevertheless, cosmological and non-cosmological effects are not well understood. Aiming to clarify the possible effects, we s…
X-Ray and Gamma-Ray Observations of the Inner Region of Mgro J2019+37
Paredes, J. M.; Zabalza, V.
In order to better understand the puzzling extended TeV source MGRO J2019+37, we have performed a multiwavelength campaign from radio to X-ray covering most of its extent. Here we present an X-ray mosaic including a new observation and two archival observations performed by the X-ray observatory XMM-Newton. We have also observed the source with th…
