An Intriguing Solar Microflare Observed with RHESSI, Hinode and TRACE

I. G. Hannah, S. Krucker, H. S. Hudson +2

Investigate particle acceleration and heating in a solar microflare. In a microflare with non-thermal emission to remarkably high energies ( keV), we investigate the hard X-ra…

The Detection of Far Ultraviolet Line Emission from Balmer-Dominated Supernova Remnants in the Large Magellanic Cloud

Parviz Ghavamian, William P. Blair, Ravi Sankrit +2

We present the first far ultraviolet (FUV) spectra of the four known Balmer-dominated supernova remnants (SNRs) in the Large Magellanic Cloud, acquired with the Far Ultraviolet Spe…

Uncovering the Nature of the X-ray Transient 4U 1730-22: Discovery of X-ray Emission from a Neutron Star in Quiescence with Chandra

John A. Tomsick, Dawn M. Gelino, Philip Kaaret

The X-ray transient, 4U 1730-22, has not been detected in outburst since 1972, when a single outburst was detected by the Uhuru satellite. This neutron star or black hole X-ray bin…

The Ultraviolet-Optical Color-Magnitude Diagram III: Constraints on Evolution from the Blue to Red Sequence

D. Christopher Martin, Ted K. Wyder, David Schiminovich +17

We introduce a new quantity, the mass flux density of galaxies evolving from the blue sequence to the red sequence. We propose a simple technique for constraining this mass flux us…

The Troublesome Broadband Evolution of GRB 061126: Does a Grey Burst Imply Grey Dust?

D. A. Perley, J. S. Bloom, N. R. Butler +18

We report on observations of a gamma-ray burst (GRB 061126) with an extremely bright (R ~ 12 mag at peak) early-time optical afterglow. The optical afterglow is already fading as a…
