A multi-wavelength study of the starburst galaxy NGC 7673
Paola Castangia, Anna Pasquali, Piero Benvenuti
HST/WFPC2 images resolved NGC 7673 into a large number of star clusters. Among these, 31 fall inside the IUE large aperture, which was used to acquire an integrated ultraviolet spe…
Multi-scalar black holes with contingent primary hair: Mechanics and stability
S. Mignemi, D. L. Wiltshire
We generalize a class of magnetically charged black holes holes non-minimally coupled to two scalar fields previously found by one of us [gr-qc/9910041] to the case of multiple sca…
The geometry of symplectic pairs
G. Bande, D. Kotschick
We study the geometry of manifolds carrying symplectic pairs consisting of two closed 2-forms of constant ranks, whose kernel foliations are complementary. Using a variation of the…
The double pulsar -- A new testbed for relativistic gravity
M. Kramer, A. G. Lyne, M. Burgay +9
The first ever double pulsar, discovered by our team a few months ago, consists of two pulsars, one with period of 22 ms and the other with a period of 2.7 s. This binary system wi…
