Overview

This table contains a catalog of radio afterglow observations of gamma-ray bursts (GRBs) over a 14 year period from 1997 to 2011. This sample of 304 afterglows consists of 2,995 flux density measurements (including upper limits) at frequencies between 0.6 GHz and 660 GHz, with the majority of data taken in the 8.5-GHz frequency band (1,539 measurements). The authors use this dataset to carry out a statistical analysis of the radio-selected sample. The detection rate of radio afterglows stayed unchanged almost at 31% before and after the launch of the Swift satellite. The canonical long-duration GRB radio light curve at 8.5 GHz peaks at three to six days in the source rest frame, with a median peak luminosity of 1031 erg/s/Hz. The peak radio luminosities for short-hard bursts, X-ray flashes, and the supernova-GRB classes are an order of magnitude or more fainter than this value. There are clear relationships between the detectability of a radio afterglow and the fluence or energy of a GRB, and the X-ray or optical brightness of the afterglow. However, the authors find few significant correlations between these same GRB and afterglow properties and the peak radio flux density. In their paper, they also produce synthetic light curves at centimeter and millimeter bands using a range of blast wave and microphysics parameters derived from multi-wavelength afterglow modeling, and use them to compare with the radio sample. Finding agreement, the authors extrapolate this behavior to predict the centimeter and millimeter behavior of GRBs which will observed by the Expanded Very Large Array and the Atacama Large Millimeter Array.

The compiled sample consists of 304 GRBs observed with radio telescopes between 1997 January and 2011 January, along with the 2011 April 28 Fermi burst, GRB 110428A. The sample consists of a total of 2,995 flux density measurements taken in the frequency range from 0.6 to 660 GHz and spanning a time range from 0.026 to 1,339 days. Most of the afterglows (270 in total) in this sample were observed as part of VLA radio afterglow programs, whereas 15 bursts were observed by the Expanded VLA (EVLA), and 19 southern bursts with the Australia Telescope Compact Array (ATCA). This catalog describes the radio, optical and X-ray afterglow detections (see Section 2.2 of the reference paper): out of the 304 bursts, 123 bursts were observed in the pre-Swift epoch from 1997 until 2004. The remaining 181 bursts were observed between 2005 and 2011 April (the post-Swift epoch).

Out of the 95 radio-detected afterglows (see Section 2.2 of the reference paper), 63 had radio lightcurves (i.e., three or more detections in a single radio band), whereas 32 bursts had less than three detections. For the GRBs for which the light curves were available, the authors determined the peak flux density and the time of the peak in the VLA frequency bands (i.e., 1.4 GHz, 4.9 GHz, 8.5 GHz, 15 GHz, and 22.5 GHz bands) by fitting the data with forward shock formula of the form (Frail 2005, IAU Coll. 192, p. 451) given in equation (1) of the reference paper. This formula may not accurately represent the full complexity of the radio lightcurve evolution. However, it is good enough to determine the approximate values for the peak flux density Fm and the time of the peak tm. See the discussion in Section 3.5 of the reference paper for more details and some caveats. For the remaining bursts, the flux density values were taken directly from the data, and hence do not have the best-fit errors for the peak flux, peak time and rest-frame peak time parameters Fm, tm and tm/(1+z), respectively.

Provenance

This table was created by the HEASARC in November 2013 based on CDS catalog J/ApJ/746/156 files table1.dat and table4.dat.

Parameters

Name
The gamma-ray burst designation in the standard date-based YY-MM-DD format, e.g., 'GRB 970228[N]' for a burst which occurred in 1997 on Feb 28. For dates on which more than one GRB was detected, suffices 'A', 'B', etc., are added.

Source_Flag
This source flag parameter contains codes indicating notes concerning specific GRBs with the following meanings:

    m = Double jet break.
    n = SN/GRB (GRB with possible SN association). See section 2.1 of ref.
    o = SHB (short-hard burst).
    p = XRF (X-ray flash).
    q = Galactic transient?
    r = Also observed with WSRT (Westerbork Synthesis Radio Telescope).
  

The HEASARC notes that the value of 'r' occurs for only one GRB (090423) and likely should have been used for the radio_telescope_flag parameter value then for the source_flag value.

Instrument_Code
This flag parameter indicates the mission or instrument which discovered the GRB, coded as follows:

    A = ASM;
    B = BeppoSAX;
    F = Fermi;
    H = HETE;
    I = INTEGRAL,
    P = PCA;
    S = Swift;
   sA = superAGILE,
    T = IPN Triangulation.
  

RA
The Right Ascension of the GRB in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 0.1 seconds of time for GRBs which occurred in the period 1997 from 2001 inclusive, and to 0.01 seconds of time for GRBs which occurred in the period 2002 to 2011 inclusive, with a few exceptions, viz., GRB 031111 (precision of 1 s), GRB 090328 (precision of 0.1 s) and GRB 090902B (precision of 0.1 s).

Dec
The Declination of the GRB in the selected equinox. This was given in J2000.0 equatorial coordinates to a precision of 1 arcseconds for GRBs which occurred in the period 1997 from 2001 inclusive, and to 0.1 arcseconds for GRBs which occurred in the period 2002 to 2011 inclusive.

LII
The Galactic Longitude of the GRB.

BII
The Galactic Latitude of the GRB.

Xray_Ag_Flag
This flag parameter indicates the detection ('Y') or not ('N') of the GRB afterglow in the X-ray band; 'X' means that the burst was not observed in this band, while 'Y?' means that the observation was made but that the detection could not be confirmed.

Opt_Ag_Flag
This flag parameter indicates the detection ('Y') or not ('N') of the GRB afterglow in the optical band; 'X' means that the burst was not observed in this band, while 'Y?' means that the observation was made but that the detection could not be confirmed.

Radio_Ag_Flag
This flag parameter indicates the detection ('Y') or not ('N') of the GRB afterglow in the radio band; 'X' means that the burst was not observed in this band, while 'Y?' means that the observation was made but that the detection could not be confirmed.

Radio_Telescope
The (primary) radio telescope used to observe the corresponding burst: ATCA, EVLA or VLA.

Radio_Telescope_Flag
This flag parameter indicates additional radio telescope(s) used to observe the burst in addition to the one specified by' the radio_telescope parameter, coded as follows:

    l = Observed with WSRT, VLBA, Ryle, ATCA and GMRT in addition to VLA/EVLA;
    r = Also observed with WSRT (Westerbork Synthesis Radio Telescope);

Ref_Codes
The coded references for the properties of the GRB in the following order: T90, z, fluence, bolometric isotropic energy, X-ray flux at 11 hr, optical flux density at 11 hr, jet break time tj and density n. If a particular parameter value is empty, then the ref_code has been given a value of '[]'. However, a ref_code value of '[]' for a non-empty corresponding parameter value means that the authors have estimated the values themselves using GCN circulars, and that this paper itself is the reference source. The numerical reference codes are as follows:

The time of the peak of the radio afterglow, tm, in days since the GRB, in the observer's frame and at the corresponding frequency radio_freq_6. This is obtained as discussed in the Overview above.

Peak_Time_6_Error
The error in the time of the peak of the radio afterglow, tm, in days since the GRB, in the observer's frame and at the corresponding frequency. This is not given for those bursts for which the value was taken directly from the data rather than using a fit with the forward shock formula.

Rf_Peak_Time_6
The time of the peak of the radio afterglow, tm/(1+z), in days since the GRB, corrected to the rest-frame as shown, for bursts with known redshifts, at the corresponding frequency radio_freq_6. The authors did not estimate the rest-frame peak time for bursts with unknown redshifts.

Rf_Peak_Time_6_Error
The error in the rest-frame time of the peak of the radio afterglow, tm/(1+z), in days since the GRB, at the corresponding frequency. This is not given for those bursts for which the value was taken directly from the data rather than using a fit with the forward shock formula.
