Abstract
To investigate the poorly constrained sub-mm counts and spectral properties of blazars we searched for these in the Herschel-ATLAS (H-ATLAS) science demonstration phase (SDP) survey catalog. We cross-matched 500 μm sources brighter than 50 mJy with the FIRST radio catalogue. We found two blazars, both previously known. Our study is among the first blind blazar searches at sub-mm wavelengths, i.e., in the spectral regime where little is still known about the blazar SEDs, but where the synchrotron peak of the most luminous blazars is expected to occur. Our early results are consistent with educated extrapolations of lower frequency counts and question indications of substantial spectral curvature downwards and of spectral upturns at mm wavelengths. One of the two blazars is identified with a Fermi/LAT γ-ray source and a WMAP source. The physical parameters of the two blazars are briefly discussed. These observations demonstrate that the H-ATLAS survey will provide key information about the physics of blazars and their contribution to sub-mm counts.

We cross-matched 500 μm sources brighter than 50 mJy with the FIRST radio catalogue. We found two blazars, both previously known. Our study is among the first blind blazar searches at sub-mm wavelengths, i.e., in the spectral regime where little is still known about the blazar SEDs, but where the synchrotron peak of the most luminous blazars is expected to occur. Our early results are consistent with educated extrapolations of lower frequency counts and question indications of substantial spectral curvature downwards and of spectral upturns at mm wavelengths. One of the two blazars is identified with a Fermi/LAT γ-ray source and a WMAP source. The physical parameters of the two blazars are briefly discussed. These observations demonstrate that the H-ATLAS survey will provide key information about the physics of blazars and their contribution to sub-mm counts.</div></front></TEI><inist><standard h6="B"><pA><fA01 i1="01" i2="1"><s0>0004-6361</s0></fA01><fA02 i1="01"><s0>AAEJAF</s0></fA02><fA03 i2="1"><s0>Astron. astrophys. : (Berl., Print)</s0></fA03><fA05><s2>518</s2></fA05><fA06><s2>1</s2></fA06><fA08 i1="01" i2="1" l="ENG"><s1>Herschel-ATLAS: Blazars in the science demonstration phase field</s1></fA08><fA11 i1="01" i2="1"><s1>GONZALEZ-NUEVO (J.)</s1><s9>comment.</s9></fA11><fA11 i1="02" i2="1"><s1>DE ZOTTI (G.)</s1></fA11><fA11 i1="03" i2="1"><s1>ANDREANI (P.)</s1></fA11><fA11 i1="04" i2="1"><s1>BARTON (E.

We cross-matched 500 μm sources brighter than 50 mJy with the FIRST radio catalogue. We found two blazars, both previously known. Our study is among the first blind blazar searches at sub-mm wavelengths, i.e., in the spectral regime where little is still known about the blazar SEDs, but where the synchrotron peak of the most luminous blazars is expected to occur. Our early results are consistent with educated extrapolations of lower frequency counts and question indications of substantial spectral curvature downwards and of spectral upturns at mm wavelengths. One of the two blazars is identified with a Fermi/LAT γ-ray source and a WMAP source. The physical parameters of the two blazars are briefly discussed. These observations demonstrate that the H-ATLAS survey will provide key information about the physics of blazars and their contribution to sub-mm counts.</s0></fC01><fC02 i1="01" i2="3"><s0>001E03</s0></fC02><fC03 i1="01" i2="3" l="FRE"><s0>Atlas</s0><s5>26</s5></fC03><fC03 i1="01" i2="3" l="ENG"><s0>Atlas</s0><s5>26</s5></fC03><fC03 i1="02" i2="X" l="FRE"><s0>Blazar</s0><s5>27</s5></fC03><fC03 i1="02" i2="X" l="ENG"><s0>Blazar</s0><s5>27</s5></fC03><fC03 i1="03" i2="X" l="FRE"><s0>Propriété spectrale</s0><s5>28</s5></fC03><fC03 i1="03" i2="X" l="ENG"><s0>Spectral properties</s0><s5>28</s5></fC03><fC03 i1="03" i2="X" l="SPA"><s0>Propiedad espectral</s0><s5>28</s5></fC03><fC03 i1="04" i2="3" l="FRE"><s0>Catalogue astronomique</s0><s5>29</s5></fC03><fC03 i1="04" i2="3" l="ENG"><s0>Astronomical catalogues</s0><s5>29</s5></fC03><fC03 i1="05" i2="3" l="FRE"><s0>Courbure</s0><s5>30</s5></fC03><fC03 i1="05" i2="3" l="ENG"><s0>Curvature</s0><s5>30</s5></fC03><fC03 i1="06" i2="X" l="FRE"><s0>Source Rγ</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="ENG"><s0>Gamma ray source</s0><s5>31</s5></fC03><fC03 i1="06" i2="X" l="SPA"><s0>Fuente Rγ</s0><s5>31</s5></fC03><fC03 i1="07" i2="X" l="FRE"><s0>Paramètre physique</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="ENG"><s0>Physical parameter</s0><s5>32</s5></fC03><fC03 i1="07" i2="X" l="SPA"><s0>Parámetro físico</s0><s5>32</s5></fC03><fC03 i1="08" i2="3" l="FRE"><s0>Objet BL Lacertae</s0><s5>33</s5></fC03><fC03 i1="08" i2="3" l="ENG"><s0>BL Lacertae objects</s0><s5>33</s5></fC03><fC03 i1="09" i2="3" l="FRE"><s0>Quasar</s0><s5>34</s5></fC03><fC03 i1="09" i2="3" l="ENG"><s0>Quasars</s0><s5>34</s5></fC03><fC03 i1="10" i2="3" l="FRE"><s0>Radiosource cosmique</s0><s5>35</s5></fC03><fC03 i1="10" i2="3" l="ENG"><s0>Cosmic radio sources</s0><s5>35</s5></fC03><fN21><s1>059</s1></fN21><fN44 i1="01"><s1>OTO</s1></fN44><fN82><s1>OTO</s1></fN82></pA></standard><server><NO>PASCAL 11-0086154 INIST</NO><ET>Herschel-ATLAS: Blazars in the science demonstration phase field</ET><AU>GONZALEZ-NUEVO (J.); DE ZOTTI (G.); ANDREANI (P.); BARTON (E.
