A Decade-Baseline Study of the Plasma States of Ejecta Knots in Cassiopeia A

Posted by klaurent MIT

Kavli Affiliate: Sarah N. T. Heine | Summary:We present the analysis of 21 bright X-ray knots in the Cassiopeia A supernova remnant from observations spanning 10 yr. We performed a comprehensive set of measurements to reveal the kinematic and thermal state of the plasma in each knot, using a combined analysis of two high energy […]

Elliptic genera of two-dimensional N=2 gauge theories with rank-one gauge groups

Posted by klaurent Tokyo

Kavli Affiliate: Kentaro Hori | Summary:We compute the elliptic genera of two-dimensional N=(2,2) and N=(0,2) gauged linear sigma models via supersymmetric localization, for rank-one gauge groups. The elliptic genus is expressed as a sum over residues of a meromorphic function whose argument is the holonomy of the gauge field along both the spatial and the […]
