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...
GRB051022: physical parameters and extinction of a prototype dark burst (2007)
Rol, Evert, Van Der Horst, Alexander, Wiersema, Klaas, Patel, Sandeep K., Levan, Andrew, Nysewander, Melissa, ...
GRB051022 was undetected to deep limits in early optical observations, but precise astrometry from radio and X-ray showed that it most likely originated in a galaxy at z~0.8. We report radio,...
Levan, Andrew, Fruchter, Andrew, Rhoads, James, Mobasher, Bahram, Tanvir, Nial, Gorosabel, Javier, ...
We present near-infrared (nIR) and optical observations of the afterglow of GRB 030115. Discovered in an infrared search at Kitt Peak 5 hours after the burst trigger, this afterglow is amongst the...
A near-IR spectrum of the DO white dwarf RE J0503-285 (2005)
Dobbie, Paul, Burleigh, Matt, Levan, Andrew, Barstow, Martin, Napiwotzki, Ralf, Hubeny, Ivan, ...
We present a near-IR spectroscopic analysis of the intriguing DO white dwarf RE J0503-285. The IR spectrum fails to reveal evidence of the presence of a spatially unresolved, cool, late-type...
Levan, Andrew, Patel, Sandeep, Kouveliotou, Chryssa, Fruchter, Andrew, Rhoads, James, Rol, Evert, ...
X-ray Flashes (XRFs) are, like Gamma-Ray Bursts (GRBs), thought to signal the collapse of massive stars in distant galaxies. Many models posit that the isotropic equivalent energies of XRFs are lower...
GRB 020410: A Gamma-ray burst afterglow discovered by its supernova light (2004)
Levan, Andrew, Nugent, Peter, Fruchter, Andrew, Burud, Ingunn, Branch, David, Rhoads, James, ...
We present the discovery and monitoring of the optical transient (OT) associated with GRB 020410. The fading OT was found by Hubble Space Telescope (HST) observations taken 28 and 65 days after burst...
Optical Photometry of GRB 021004: The First Month (2002)
Holland, Stephen T., Weidinger, Michael, Fynbo, Johan P. U., Gorosabel, Javier, Hjorth, Jens, Pedersen, Kristian, ...
We present U,B,V,R_C,and I_C photometry of the optical afterglow of the gamma-ray burst GRB 021004 taken at the Nordic Optical Telescope between approximately eight hours and 30 days after the burst....
