The Role of Dust in GRB Afterglows
نویسنده
چکیده
We show that the clumpy structure of star-forming regions can naturally explain the fact that 50-70% of GRB afterglows are optical“dark.” We also show that dust echos from the GRB and its afterglow, produced by the clumpy structure of the star-forming region in which the GRB occurs, can lead to temporal variability and peaks in the NIR, optical, and UV lightcurves of GRB afterglows.

Prospects for multiwavelength polarization observations of GRB afterglows and the case GRB 030329
We explore the prospects for simultaneous, broad-band, multiwavelength polarimetric observations of GRB afterglows. We focus on the role of cosmic dust in GRB host galaxies on the observed percentage polarization of afterglows in the optical/near-infrared bands as a function of redshift. Our driving point is the afterglow of GRB 030329, for which we obtained polarimetric data in the R band and ...
متن کاملTheoretical Implications of the Gamma-Ray Burst – Supernova Connection
Although observations of circumstellar shock interactions around supernovae are generally consistent with a ρ ∝ r wind surrounding the progenitor star, this is not true for GRB (gamma-ray burst) afterglows. However, GRB 991208 and GRB 000301C may be consistent with wind interaction if the injection particle spectrum is a broken power law. Circumstellar dust echos can place constraints on supern...
متن کاملLight Curves and Spectra of Dust Echoes From Gamma - Ray Bursts and their Afterglows : Continued Evidence that GRB 970228 is Associated with a Supernova
The relative brightening and reddening of the optical afterglows of GRB 970228 and GRB 980326 around 20 – 30 days after these bursts have been attributed to supernovae, which are red (blueward of their spectral peak), and which peak in time after ≈ 20(1 + z) days. However, this direct evidence for a GRB/SN connection has recently been challenged. It has been suggested that the late afterglows o...
متن کاملGamma-Ray Burst Dust Echoes Revisited: Expectations at Early Times
Gamma-ray burst (GRB) dust echoes were first proposed as an alternative explanation for the supernova-like (SN-like) components to the afterglows of GRB 980326 and GRB 970228. However, the spectroscopic identification of Type Ic SN 2003dh associated with GRB 030329, as well as the identification of SN-like components to the afterglows of other GRBs, appears to have confirmed the GRB/SN paradigm...
متن کاملSignatures of Extragalactic Dust in Pre-swift Grb Afterglows
We present the results of a systematic analysis of gamma-ray burst afterglow spectral energy distributions (SEDs) in the optical/near-infrared bands. Our input list includes the entire world sample of afterglows observed in the preSwift era by the end of 2004 that have sufficient publicly available data. We apply various dust extinction models to fit the observed SEDs (Milky Way, Large Magellan...
