Chandra X-ray counterpart of KS 1741-293
J. Marti, J. A. Combi, D. Perez-Ramirez +4
We aim to investigate the nature of the high energy source KS 1741-293 by revisiting the radio and infrared associations proposed in the early 1990s. Our work is mostly based on th…
TeV J2032+4130: a not-so-dark Accelerator?
Yousaf M. Butt, Jorge A. Combi, Jeremy Drake +5
The HEGRA gamma-ray source TeV J2032+4130 is considered the prototypical 'dark accelerator', since it was the first TeV source detected with no firm counterparts at lower frequenci…
XMM detection of the supernova remnant G337.2+0.1
Jorge A. Combi, Juan F. Albacete Colombo, Gustavo E. Romero +1
We report the first XMM detection of the SNR candidate G337.2+0.1 (=AX J1635.9-4719). The object shows centrally filled and diffuse X-ray emission. The emission peaks in the hard 3…
Multi-wavelength afterglow observations of the high redshift GRB 050730
S. B. Pandey, A. J. Castro-Tirado, S. McBreen +22
GRB 050730 is a long duration high-redshift burst (z=3.967) discovered by Swift. The afterglow shows variability and is well monitored over a wide wavelength range. We present comp…
Multi-wavelength properties of the high-energy bright Seyfert 1 galaxy IGR J18027-1455
J. A. Combi, M. Ribo, J. Marti +1
A new sample of hard X-ray sources in the Galactic Plane is being revealed by the regular observations performed by the INTEGRAL satellite. The full characterization of these sourc…
