2 Gamma-ray binaries O/Be + compact object d orbits dominant gamma-ray emission. most likely rotation powered by high E pulsar expected phase in binary evolution LS I spectral energy distribution (Zdziarski et al. 2009)
3 Radio morphology along orbit milliarcsecond scales show comet-like behaviour Dhawan+ 2006, Albert (LS I ); Ribó (LS 5039); Moldón (PSR B1259) Dhawan et al LS I
4 Gamma-ray binaries detected detected + orbital variability system Porb radio X-ray GeV TeV PSR B LS 5039 LS I HESS J FGL J psr Be 1237? O 3.9? Be 26.5? Be 320? O 16.6 NB1: gamma-ray emission not dominant in Cyg X-3 & V407 Cyg NB2: PSR J , XSSJ low-mass gamma-ray binaries? Tam et al. 2010, Hill et al. 2011
5 Gamma-ray binaries detected detected + orbital variability system Porb radio X-ray GeV TeV PSR B LS 5039 LS I HESS J FGL J psr Be 1237? O 3.9? Be 26.5? Be 320? O 16.6 Origin of orbital modulation in γ-ray?
6 γ-ray orbital modulations inverse Compton on star photons orbit seen face on apastron periastron apastron periastron apastron periastron inverse Compton (GeV)
7 γ-ray orbital modulations inverse Compton on star photons pair production on star photons (opacity) orbit seen face on apastron periastron apastron periastron apastron periastron inverse Compton (GeV) + pair production above threshold (TeV)
8 γ-ray orbital modulations inverse Compton on star photons: anisotropic pair production on star photons (opacity) orbit seen edge on inf conj sup conj inf conj sup conj inf conj sup conj to observer inverse Compton (GeV)
9 γ-ray orbital modulations inverse Compton on star photons: anisotropic pair production on star photons (opacity): anisotropic orbit seen edge on inf conj sup conj inf conj sup conj inf conj sup conj to observer inverse Compton (GeV) + pair production above threshold (TeV) studies by different groups: Bednarek et al.; Kirk et al; Khangulyan & Bosch-Ramon et al.; GD, Cerutti & Henri; Sierpowska-Bartosik & Torres; Takata & Taam; Yamaguchi & Takahara...
10 γ-ray orbital modulations inverse Compton on star photons: anisotropic pair production on star photons (opacity): anisotropic orbit seen edge on inf conj sup conj inf conj sup conj inf conj sup conj to observer inverse Compton (GeV) + pair production above threshold (TeV) identify emission mechanism distinguish intrinsic variability from variability due to observer geometry Bednarek ; Khangulyan & Bosch-Ramon, Sierpowska-Bartosik & Torres, GD Cerutti Henri, Takata & Taam, Yamaguchi & Takahara
11 Example: LS 5039 Cerutti et al massive star radiation field + orbit fixes emission <B>~a few G
12 Possible complications significant pair cascade emission at superior conjunction total!!!! e -! e + e - e + e + e -!! pairs Cerutti et al. 2010
13 Possible complications significant pair cascade emission at superior conjunction bulk doppler boost in shocked wind modifies lightcurve VHE β=0 β=c/3 X-ray GD+ 2010
14 Puzzling lightcurve of PSR B Fermi/LAT lightcurve (Abdo et al. 2011) orbit close to periastron erg/s spindown pulsar in 3.5 year orbit around Be star Fermi/LAT detection at periastron mid-december 2010 brighter in February (near inf. conjunction)
15 Puzzling lightcurve of PSR B Fermi/LAT lightcurve (Abdo et al. 2011) expected inverse Compton on star photons Pétri & GD 2011 what caused the brightening? Inv. Compton on star not enough Be disk (!0, free-free...)? HE sync? Doppler boost? IC on other fields?... high Lγ nearly all spindown power radiated away at peak
16 Puzzling spectrum of LS I modulation: inverse Compton on star offset like PSR B Abdo et al au 26 d to observer HE peak offset from IC expectations HE and VHE long term variability
17 Puzzling spectrum of LS I modulation: inverse Compton on star offset like PSR B spectrum: two populations of HE particles? (also LS 5039) Abdo et al HE peak offset from IC expectations HE and VHE long term variability exponential cutoff at GeV (like Fermi pulsars?!)
18 Puzzling spectrum of LS I modulation: inverse Compton on star offset like PSR B spectrum: two populations of HE particles? (also LS 5039) curvature radiation in magnetosphere no orbital modulation expected magnetosphere pulsar wind nebula exponential cutoff at GeV (like Fermi pulsars?!)
19 Puzzling spectrum of LS I modulation: inverse Compton on star offset like PSR B spectrum: two populations of HE particles? (also LS 5039) curvature radiation in magnetosphere no orbital modulation expected striped wind pulsar wind nebula Pétri & GD 2011 inverse Compton in striped wind? line-of-sight crosses stripes pulsed GeV emission exponential cutoff at GeV (like Fermi pulsars?!)
20 γ-ray binaries: conclusions 5 binaries with O/Be star + dominant γ-ray emission powered by spindown of companion pulsar (tbc) γ-ray orbital modulation natural outcome of inverse Compton pair production on stellar photons. complications: pair cascade, Doppler boosting... but fails to explain peak phase in PSR B1259, LS I other radiative processes? related to both having a Be companion? striped wind pulsar wind nebula γ-ray spectrum indicates two particle populations striped wind at GeV + pulsar wind nebula at TeV?
