On the interpretation of the spectral--energy correlations in long Gamma--Ray Bursts
L. Nava, G. Ghisellini, G. Ghirlanda +2
Recently, Liang & Zhang (2005) found a tight correlation involving only observable quantities, namely the isotropic emitted energy , the energy of the peak of the prompt…
The Cooling of Compact Stars
Dany Page, Ulrich Geppert, Fridolin Weber
The cooling of a compact star depends very sensitively on the state of dense matter at supranuclear densities, which essentially controls the neutrino emission, as well as on the s…
HD 172189: An eclipsing and spectroscopic binary with a Delta Sct-ttype pulsating component in an open cluster
S. Martin-Ruiz, P. J. Amado, J. C. suarez +4
We present a study based on more than 2500 uvby-measurements collected on HD 172189, a new eclipsing binary system with a Delta Sct-type pulsating component that belongs to the ope…
Probing the Local Group Medium Toward Mkn 421 with Chandra and FUSE
Rik J. Williams, Smita Mathur, Fabrizio Nicastro +7
We report the detection of highly-ionized gas at z~0 seen in resonant UV and X-ray absorption lines toward the z=0.03 blazar Mkn 421. A total of 13 X-ray and 3 UV lines were measur…
The creation of the Helix planetary nebula (NGC 7293) by multiple events
J. Meaburn, P. Boumis, J. A. Lopez +4
A deep, continuum-subtracted, image of NGC 7293 has been obtained in the light of the Halpha+[N II] emission lines. New images of two filamentary halo stuctures have been obtained…
Detection of satellite remnants in the Galactic Halo with Gaia - I. The effect of the Galactic background, observational errors and sampling
Anthony Brown, Hector Velazquez, Luis Aguilar +1
We address the problem of identifying remnants of satellite galaxies in the halo of our galaxy with Gaia data. The remnants have to be extracted from a very large data set (of orde…
