Dehn surgeries that yield fibred --manifolds
Yi Ni
We study Dehn surgeries on null-homotopic knots that yield fibred --manifolds when an additional (but natural) homological restriction is imposed. The major tool used is Gabai's…
Towards a non-perturbative matching of HQET and QCD with dynamical light quarks
Michele Della Morte, Patrick Fritzsch, Jochen Heitger +3
We explain how the strategy of solving renormalization problems in HQET non-perturbatively by a matching to QCD in finite volume can be implemented to include dynamical fermions. A…
Supplementary Information for "A 15.65 solar mass black hole in an eclipsing binary in the nearby spiral galaxy Messier 33"
Jerome A. Orosz, Jeffrey E. McClintock, Ramesh Narayan +8
This Supplementary Information provides details about the spectral extraction (crowding issues and the removal of nebular lines), a discussion about the distance to M33, a model fo…
Nucleon and Nucleon to Delta Axial form factors from Lattice QCD
C. Alexandrou, G. Koutsou, Th. Leontiou +2
We present results on the nucleon axial vector form factors and in the quenched theory and using two degenerate flavors of dynamical Wilson fermions for momen…
Nonthermal Bremsstrahlung vs. Synchrotron Radiation: Cas A
G. E. Allen, M. D. Stage, J. C. Houck
We performed a spectral analysis of some Chandra ACIS and RXTE PCA data for the supernova remnant Cas A. A very large (1.1 Ms) ACIS data set is used to identify regions dominated b…
Chandra X-Ray Observation of the Globular Cluster GLIMPSE-C01
D. Pooley, S. Rappaport, A. Levine +2
We have observed the recently discovered rich star cluster GLIMPSE-C01 for 46 ks with the Chandra X-ray Observatory. Seventeen X-ray sources with luminosities greater than 0.6e31 e…
