Evolution of stellar structure in the Small Magellanic Cloud
M. Gieles, N. Bastian, B. Ercolano
The projected distribution of stars in the Small Magellanic Cloud (SMC) from the Magellanic Clouds Photometric Survey is analysed. Stars of different ages are selected via criteria…
Suzaku Observations of the Circinus galaxy
Y. Yang, A. S. Wilson, G. Matt +2
We report Suzaku observations of the active, Compton-thick Circinus galaxy. Observations were obtained with both the X-ray Imaging spectrometer (XIS) and the Hard X-ray Detector (H…
The Sloan Lens ACS Survey. VII. Elliptical Galaxy Scaling Laws from Direct Observational Mass Measurements
Adam S. Bolton, Tommaso Treu, Leon V. E. Koopmans +5
We use a sample of 53 massive early-type strong gravitational lens galaxies with well-measured redshifts (ranging from z=0.06 to 0.36) and stellar velocity dispersions (between 175…
The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125
Adria C. Updike, Joshua B. Haislip, Melissa C. Nysewander +52
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the prese…
Scaling Laws and Temperature Profiles for Solar and Stellar Coronal Loops with Non-uniform Heating
P. C. H. Martens
The bulk of solar coronal radiative loss consists of soft X-ray emission from quasi-static loops at the cores of Active Regions. In order to develop diagnostics for determining the…
