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…
Representing complex data using localized principal components with application to astronomical data
Jochen Einbeck, Ludger Evers, Coryn Bailer-Jones
Often the relation between the variables constituting a multivariate data space might be characterized by one or more of the terms: ``nonlinear'', ``branched'', ``disconnected'', `…
Relativistic Jets and Long-Duration Gamma-ray Bursts from the Birth of Magnetars
N. Bucciantini, E. Quataert, J. Arons +2
We present time-dependent axisymmetric magnetohydrodynamic simulations of the interaction of a relativistic magnetized wind produced by a proto-magnetar with a surrounding stellar…
Magnetar Driven Bubbles and the Origin of Collimated Outflows in Gamma-ray Bursts
N. Bucciantini, E. Quataert, J. Arons +2
We model the interaction between the wind from a newly formed rapidly rotating magnetar and the surrounding supernova shock and host star. The dynamics is modeled using the two-dim…
Refined parameters of the planet orbiting HD 189733
G. A. Bakos, H. Knutson, F. Pont +13
We report on the BVRI multi-band follow-up photometry of the transiting extrasolar planet HD 189733b. We revise the transit parameters and find planetary radius RP = 1.154+/- 0.032…
Spectropolarimetry of Compton-thin Seyfert 2s
S. L. Lumsden, D. M. Alexander, J. H. Hough
We present new spectropolarimetry of a sample of nearby Compton-thin Seyfert 2 galaxies (ie those with N_H<10^23 cm^-2). We show that the detection rate of scattered broad Halpha i…
Morphology and kinematics of Lynds 1642
D. Russeil, M. Juvela, K. Lehtinen +2
The high latitude translucent molecular cloud L1642 has been mapped in the J=1-0 and J=2-1 transitions of 12CO, 13CO and C18O using the SEST radio telescope. We have analysed the m…
