Tracing the jet contribution to the mid-IR over the 2005 outburst of GRO J1655-40 via broadband spectral modeling
S. Migliari, J. A. Tomsick, S. Markoff +6
We present new results from a multi-wavelength (radio/infrared/optical/X-ray) study of the black hole X-ray binary GRO J1655-40 during its 2005 outburst. We detected, for the first…
The spectral energy distribution of quiescent black hole X-ray binaries: new constraints from Spitzer
E. Gallo, S. Migliari, S. Markoff +5
(Abridged) Among the various issues that remain open in the field of accretion onto black hole X-ray binaries (BHBs) is the way the gas accretes at very low Eddington ratios, in th…
SN 2006aj and the nature of low-luminosity gamma-ray bursts
B. E. Cobb, C. D. Bailyn, P. G. van Dokkum +1
We present SMARTS consortium optical/IR light curves of SN 2006aj associated with GRB 060218. We find that this event is broadly similar to two previously observed events SN 1998bw…
GRB 050408: An Atypical Gamma-Ray Burst as a Probe of an Atypical Galactic Environment
R. J. Foley, D. A. Perley, D. Pooley +14
The bright GRB 050408 was localized by HETE-II near local midnight, enabling an impressive ground-based followup effort as well as space-based followup from Swift. The Swift data f…
The 2002 Outburst of the Black-Hole X-ray Binary 4U 1543-47: Optical and Infrared Light Curves
M. M. Buxton, C. D. Bailyn
We have obtained simultaneous optical and near infrared observations of 4U 1543-47 during its 2002 outburst. The most striking feature of the outburst light curve is the secondary…
Discovery of a supernova associated with GRB 031203: SMARTS Optical-Infrared Lightcurves from 0.2 to 92 days
B. E. Cobb, C. D. Bailyn, P. G. van Dokkum +2
Optical and infrared monitoring of the afterglow site of gamma-ray burst (GRB) 031203 has revealed a brightening source embedded in the host galaxy, which we attribute to the prese…
