X-ray Evolution of SNR 1987A: The Radial Expansion (2009)
Racusin, Judith L., Park, Sangwook, Zhekov, Svetozar, Burrows, David N., Garmire, Gordon P., McCray, Richard
We present the evolution of the radial expansion of SNR 1987A as measured using Chandra X-ray observations taken over the last 10 years. To characterize the complex structure of the remnant and...
Late time observations of GRB080319B: jet break, host galaxy and accompanying supernova (2008)
Tanvir, Nial R., Rol, Evert, Levan, Andrew, Fruchter, Andrew, Granot, Jonathan, Svensson, Karl M., ...
The Swift-discovered GRB080319B was by far the most distant source ever observed at naked eye brightness, reaching a peak magnitude of 5.3 at a redshift of z=0.937. We present our late time optical...
The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125 (2008)
Updike, Adria C., Haislip, Joshua B., Nysewander, Melissa C., Fruchter, Andrew S., Kann, D. Alexander, Klose, Sylvio, ...
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 presence of absorption...
Broadband observations of the naked-eye y-ray burst GRB 080319B (2008)
Racusin, Judith L., Karpov, S. V., Sokolowski, M., Granot, Jonathan, Wu, Xiao Feng, Pal'shin, V., ...
Long-duration y-ray bursts (GRBs) release copious amounts of energy across the entire electromagnetic spectrum, and so provide a window into the process of black hole formation from the collapse of...

Liang, En-Wei, Racusin, Judith L., Zhang, Bing, Zhang, Bin-Bin, Burrows, David N.
The Swift/XRT data of 179 GRBs (from 050124 to 070129) and the optical afterglow data of 57 pre- and post-Swift GRBs are analyzed, in order to systematically investigate the jet-like breaks in the...
Chandra Observations of Supernova 1987A (2007)
Park, Sangwook, Burrows, David N., Garmire, Gordon P., McCray, Richard, Racusin, Judith L., Zhekov, Svetozar A.
We have been monitoring Supernova (SN) 1987A with {\it Chandra X-Ray Observatory} since 1999. We present a review of previous results from our {\it Chandra} observations, and some preliminary results...
The Swift X-ray flaring afterglow of GRB 050607 (2006)

Evolutionary Status of SNR 1987A at the Age of Eighteen (2006)
Park, Sangwook, Zhekov, Svetozar A., Burrows, David N., Garmire, Gordon P., Racusin, Judith L., McCray, Richard
$\sim$18 yr after the supernova explosion, the blast wave of SNR 1987A is entering the main body of the equatorial circumstellar material, which is causing a dramatic brightening of the remnant. We...
Swift XRT Observations of the Afterglow of XRF 050416A (2006)
Mangano, Vanessa, La Parola, Valentina, Cusumano, Giancarlo, Mineo, Teresa, Malesani, Daniele, Dyks, Jaroslaw, ...
Swift discovered XRF 050416A with the BAT and began observing it with its narrow field instruments only 64.5 s after the burst onset. Its very soft spectrum classifies this event as an X-ray flash....
Swift Observations of GRB 050603: An afterglow with a steep late time decay slope (2006)
Grupe, Dirk, Brown, Peter, Cummings, Jay, Zhang, Bing, Retter, Alon, Burrows, David N., ...
We report the results of Swift observations of the Gamma Ray Burst GRB 050603. With a V magnitude V=18.2 about 10 hours after the burst the optical afterglow was the brightest so far detected by...
