Journal ArticleDOI
Determination of the mass of the neutron star in SMC X-1, LMC X-4, and Cen X-3 with VLT/UVES
TL;DR: In this paper, a spectroscopic monitoring campaign of the OB-star companions to the eclipsing X-ray pulsars SMC X−1, LMC X−4 and Cen X−3 is presented.
Journal ArticleDOI
Gamma-Ray Burst Afterglows as Probes of Environment and Blast Wave Physics. I. Absorption by Host-Galaxy Gas and Dust
R. L. C. Starling,R. L. C. Starling,Ralph A. M. J. Wijers,Klaas Wiersema,Evert Rol,P. A. Curran,Chryssa Kouveliotou,A. J. van der Horst,M. H. M. Heemskerk +8 more
TL;DR: In this paper, the authors used a new approach to obtain limits on the absorbing columns toward an initial sample of 10 long gamma-ray bursts observed with BeppoSAX and selected on the basis of their good optical and near-infrared (NIR) coverage, from simultaneous fits to NIR, optical, and X-ray afterglow data, in count space and including the effects of metallicity.

Robust photometric redshift determinations of gamma-ray burst afterglows at z > 2
P. A. Curran,R. A. M. J. Wijers,M. H. M. Heemskerk,R. L. C. Starling,K. Wiersema,A. J. van der Horst +5 more
TL;DR: In this article, a method of simultaneous multi-parameter fitting of GRB afterglow optical and near infrared, spectral energy distributions is proposed to estimate the photometric redshift, spectral index and host extinction.
