The Stellar Halo in the Large Magellanic Cloud: Mass, Luminosity, and Microlensing Predictions
David R. Alves
Recently obtained kinematic data has shown that the Large Magellanic Cloud (LMC) possesses an old stellar halo. In order to further characterize the properties of this halo, parame…
Isolating Geometry in Weak Lensing Measurements
Jun Zhang, Lam Hui, Albert Stebbins
Given a foreground galaxy-density field or shear field, its cross-correlation with the shear field from a background population of source galaxies scales with the source redshift i…
Revealing the obscured supernova remnant Kes 32 with Chandra
Jacco Vink
I report here on the analysis and interpretation of a Chandra observation of the supernova remnant Kes 32. Kes 32 is rather weak in X-rays due to a large interstellar absorption, w…
Flares from small to large: X-ray spectroscopy of Proxima Centauri with XMM-Newton
M. Guedel, M. Audard, F. Reale +2
(Abridged) We report results from a comprehensive study of the nearby M dwarf Proxima Centauri with the XMM-Newton satellite. We find strongly variable coronal X-ray emission, with…
Modeling an X-ray Flare on Proxima Centauri: evidence of two flaring loop components and of two heating mechanisms at work
F. Reale, M. Guedel, G. Peres +1
We model in detail a flare observed on Proxima Centauri with the EPIC-PN on board XMM-Newton at high statistics and high time resolution and coverage. Time-dependent hydrodynamic l…
A Search for Short Time-Scale Optical Variability in the GRB 030329 Afterglow
N. Mirabal, J. P. Halpern, M. Bureau +1
We present a densely sampled R-band light curve of the optical afterglow of GRB 030329 obtained during the period 15.5-23 hours after the burst. This dataset allows us to search fo…
GRB 021004: A Possible Shell Nebula around a Wolf-Rayet Star Gamma-Ray Burst Progenitor
N. Mirabal, J. P. Halpern, R. Chornock +2
The rapid localization of GRB 021004 by the HETE-2 satellite allowed nearly continuous monitoring of its early optical afterglow decay, as well as high-quality optical spectra that…
Was the X-ray Afterglow of GRB 970815 Detected?
N. Mirabal, J. P. Halpern, E. V. Gotthelf +1
GRB 970815 was a well-localized gamma-ray burst (GRB) detected by the All-Sky Monitor (ASM) on the Rossi X-Ray Timing Explorer (RXTE) for which no afterglow was identified despite…
The H-alpha Light Curves and Spatial Distribution of Novae in M81
James D. Neill, Michael M. Shara
We present the results of a preliminary H-alpha survey of M81 for novae conducted over a 5 month interval using the 5' field of view camera (WFCAM) on the Calypso Telescope at Kitt…
An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
M. Burgay, N. D'Amico, A. Possenti +10
The merger of close binary systems containing two neutron stars should produce a burst of gravitational waves, as predicted by the theory of general relativity. A reliable estimate…
The detailed optical light curve of GRB 030329
Y. M. Lipkin, E. O. Ofek, A. Gal-Yam +22
(Abridged) We present densely sampled BVRI light curves of the optical transient associated with the gamma-ray burst GRB 030329, the result of a coordinated observing campaign cond…
The Mouse That Soared: High Resolution X-ray Imaging of the Pulsar-Powered Bow Shock G359.23-0.82
B. M. Gaensler, E. van der Swaluw, F. Camilo +4
We present an observation with the Chandra X-ray Observatory of the unusual radio source G359.23-0.82 ("the Mouse"), along with updated radio timing data from the Parkes radio tele…

A Review of the Distance and Structure of the Large Magellanic Cloud
David R. Alves
The average of 14 recent measurements of the distance to the Large Magellanic Cloud (LMC) implies a true modulus of 18.50 +- 0.02 mag, and demonstrates a trend in the past 2 years…
A Review of X-ray Observations of Supernova Remnants
Jacco Vink
I present a review of X-ray observations of supernova remnants with an emphasis on shell-type remnants. The topics discussed are the observation of fresh nucleosynthesis products,…

We present a summary of high-spatial resolution follow-up observations of the elliptical (E) and lenticular (S0) galaxies in the SAURON survey using the OASIS integral field spectr…
VLBA observations of z > 4 radio-loud quasars
Emmanuel Momjian, Andreea O. Petric, Christopher L. Carilli
We present high resolution (< 20 mas) observations of the radio continuum emission at 1.4 GHz from three high-redshift quasars: J1053-0016 (z=4.29), 1235-0003 (z=4.69), and J0913+5…
A SAURON look at galaxy bulges
J. Falcón-Barroso, R. Bacon, M. Bureau +8
Kinematic and population studies show that bulges are generally rotationally flattened systems similar to low-luminosity ellipticals. However, observations with state-of-the-art in…
