Cosmic Shear from Scalar-Induced Gravitational Waves
Devdeep Sarkar, Paolo Serra, Asantha Cooray +2
Weak gravitational lensing by foreground density perturbations generates a gradient mode in the shear of background images. In contrast, cosmological tensor perturbations induce a…
Magnetar Driven Bubbles and the Origin of Collimated Outflows from GRBs
N. Bucciantini, E. Quataert, J. Arons +2
We model the interaction between the wind from a newly formed rapidly rotating magnetar and the surrounding progenitor. In the first few seconds after core collapse the magnetar in…
New UltraCool and Halo White Dwarf Candidates in SDSS Stripe 82
S. Vidrih, D. M. Bramich, P. C. Hewett +16
A 2.5 x 100 degree region along the celestial equator (Stripe 82) has been imaged repeatedly from 1998 to 2005 by the Sloan Digital Sky Survey. A new catalogue of ~4 million light-…
Relativistic MHD Winds from Rotating Neutron Stars
Bucciantini, N., Thompson +7
We review here recent numerical results concerning the acceleration and collimation of relativistic outflows from neutron stars, and we discuss their implications for models of mag…
X-ray flares following short gamma-ray bursts from shock heating of binary stellar companions
Andrew I. MacFadyen, Enrico Ramirez-Ruiz, Weiqun Zhang
The discovery of long-lasting (~100 s) X-ray flares following short gamma-ray bursts initially called into question whether they were truly classical short-hard bursts. Opinion ove…
HST/STIS observations of the HeII Gunn-Peterson effect towards HE 2347-4342
Alain Smette, Sara R. Heap, Gerard M. Williger +3
We present an HST STIS spectrum of the HeII Gunn-Peterson effect towards HE2347-4342. Compared to the previous HST GHRS data obtained by Reimers et al. (1997), the STIS spectrum ha…
