Spacetime singularities and incompleteness: epistemic and ontological remarks
Gustavo E. Romero
I argue that spacetime singularities entail no ontological commitment to material entities. First, I show that Penrose's singularity theorem is best understood as a theorem of inco…
X-ray study of bow shocks in runaway stars
M. De Becker, M. V. del Valle, G. E. Romero +2
Massive runaway stars produce bow shocks through the interaction of their winds with the interstellar medium, with the prospect for particle acceleration by the shocks. These objec…
An investigation into the fraction of particle accelerators among colliding-wind binaries. Towards an extension of the catalogue
M. De Becker, P. Benaglia, G. E. Romero +1
Particle-accelerating colliding-wind binaries (PACWBs) are multiple systems made of early-type stars able to accelerate particles up to relativistic velocities. The relativistic pa…
Is the bowshock of the runaway massive star HD 195592 a Fermi source?
M. V. del Valle, G. E. Romero, M. De Becker
HD 195592 is an O-type super-giant star, known as a well-established runaway. Recently, a Fermi gamma-ray source (2FGL J2030.7+4417) with a position compatible with that of HD 1955…
INTEGRAL-ISGRI observations of the CygOB2 region: earching for hard X-ray point sources in a region containing several non-thermal emitting massive stars
M. De Becker, G. Rauw, J. M. Pittard +3
Aims: We analyze INTEGRAL-ISGRI data in order to probe the hard X-ray emission (above 20 keV) from point sources in the Cyg OB2 region and to investigate the putative non-thermal h…
In search for natural wormholes
Luis A. Anchordoqui, G. E. Romero, Diego F. Torres +1
We have investigated 631 time profiles of gamma ray bursts from the BATSE database searching for observable signatures produced by microlensing events related to natural wormholes.…
