1 Was the Christmas star a gamma ray burst? Drejc Kopač Faculty of Mathematics and Physics University of Ljubljana 20. December 2011

2 Overview 1 Star of Bethlehem 2 GRBs quick overview Prompt GRB Afterglow SNe 3 GRB A: observations Gamma-ray emission X-ray emission Optical emission 4 GRB A: explanations Models Tidal disruption Supernova Similar events? 5 Conclusion

3 Story

4 Explanations Fulfillment of prophecy, Astronomical object, Astrological event, Pious fiction

5 Gamma-ray emission: light curves short vs. long

6 X-ray emission: prompt tail & afterglow Nousek et al. 2006

7 X-ray emission: prompt tail & afterglow Zhang et al. 2006; Canonical X-ray light curve

8 X-ray emission: prompt tail & afterglow Racusin et al. 2011

9 Optical emission: afterglow Fireball scenario: external FS synchrotron emission Kann et al. 2010, 2011

10 LGRBs & SNe Ibc: core collapse Optical bump Sparre 2011

11 LGRBs & SNe Ibc: core collapse Spectrum Sparre 2011 Modjaz et al. 2006

12 GRB A: redshift z No redshift!

13 GRB A: gamma-ray emission BAT data (T 90 > 2000 s): Thöne et al kev tot. fluence erg cm 2 Spectrum fit: cutoff PL (E pk = 38 ± 20 kev) or a BB (kt = 10.1 ± 1.1 kev) low S/N

14 GRB A: X-ray emission XRT data (light curve):

15 GRB A: X-ray emission XRT data (spectrum): Campana et al Thöne et al Accretion disk black body and a boundary layer PL and BB

16 GRB A: optical emission Optical light curve: Campana et al Faint afterglow: t t 0 = 1.6 hours, R = 22.1 ± 0.1, I = 21.5 ± 0.2 Reddening at later times (t t 0 20 days)

17 GRB A: optical image Optical image from GTC (10.4m): Thöne et al Faint host galaxy : r = 26.9 ± 0.14, g = ± 0.27

18 GRB A: optical spectrum Spectrum from GTC (10.4m): Thöne et al No emission feature in spectrum at z = (smooth blue continuum).

19 GRB A: models Two models: Who is right?

20 GRB A: movie vs.

21 GRB A: Tidal disruption Comets hitting the Sun Extragalactic models (GRBs, SNe, blazars) unlikely: total energy arguments, faintness of the optical counterpart and putative host Galactic models (X-ray binaries, magnetars and flare stars) ruled out: extreme faint quiescent counterpart, relatively high Galactic latitude Disruptive event involving a compact object. But: the rate of such event is rather low: NS hardly retains its original population of small bodies due to SN event.

22 GRB A: Tidal disruption Phenomenological model of tidal disruption fit: Campana et al After 20 days 500 hours: transition of the accretion disk to a cold solution

23 GRB A: Tidal disruption SED is best fit with DiskBB + COMPTT (boundary layer): Campana et al Emission from the accretion disk and the NS surface heated by the accreting matter, which reach the slowly rotating NS at boundary layer, where a large fraction of the accretion energy is released (Comptonization of soft photons).

24 GRB A: Supernova Very strange SN and very special case: Faintest SN associated with LGRBs Faintest host galaxy at z = 0.33 Sparse data with large spread!

25 GRB A: Supernova SN model: Thöne et al Fit with template broad-line Type Ic SN 1998bw The BB evolves from K at 0.07 days to 5000 K at 18 days

26 GRB A: Supernova From SN fit, one can obtain the redshift: Thöne et al Redshift consistent with the N H analysis.

27 GRB/XRF and GRB A Thöne et al GRB A: z=0.677

28 Conclusion Maybe the star of Bethlehem wasn t a star at all. (Neil Young)
