Intrinsic properties of a complete sample of HETE-2 gamma-ray bursts. A measure of the GRB rate in the Local Universe
A. Pélangeon, J. -L. Atteia, Y. E. Nakagawa +32
Aims: Taking advantage of the forthcoming Catalog of the HETE-2 mission, the aim of this paper is to evaluate the main properties of HETE-2 GRBs - the E_peak, the T_90 and the E_is…
Chandra and Swift observations of the quasi-persistent neutron star transient EXO 0748-676 back to quiescence
N. Degenaar, R. Wijnands, M. T. Wolff +8
The quasi-persistent neutron star X-ray transient and eclipsing binary EXO 0748-676 recently started the transition to quiescence following an accretion outburst that lasted more t…
Mass models and environment of the new quadruply lensed quasar SDSS J1330+1810
Masamune Oguri, Naohisa Inada, Jeffrey A. Blackburne +5
We present the discovery of a new quadruply lensed quasar. The lens system, SDSS J1330+1810 at z_s=1.393, was identified as a lens candidate from the spectroscopic sample of the Sl…
Kinematical Structure of the Magellanic System
Roeland P. van der Marel, Nitya Kallivayalil, Gurtina Besla
We review our understanding of the kinematics of the LMC and the SMC, and their orbit around the Milky Way. The line-of-sight velocity fields of both the LMC and SMC have been mapp…
The Binarity of the Magellanic Clouds and the Formation of the Magellanic Stream
Gurtina Besla, Nitya Kallivayalil, Lars Hernquist +4
The HST proper motion (PM) measurements of the Clouds have severe implications for their interaction history with the Milky Way (MW) and with each other. The Clouds are likely on t…
New Analysis of the Proper Motions of the Magellanic Clouds using HST/WFPC2
Nitya Kallivayalil, Roeland P. van der Marel, Jay Anderson +2
In HST Cycles 11 and 13 we obtained two epochs of ACS/HRC data for fields in the Magellanic Clouds centered on background quasars. We used these data to determine the proper motion…
