En galax som hyser en AGN, en värdgalax, kallas <b>aktiv galax</b>. </p><p>Den kraftiga strålningen från AGN antas vara resultat av att kärnan drar till sig stora mängder material från omgivningen, så kallad <a href="/wiki/Ackretionsskiva" title="Ackretionsskiva">ackretion</a>, till ett <a href="/wiki/Supermassiva_svarta_h%C3%A5l" class="mw-redirect" title="Supermassiva svarta hål">supermassivt svart hål</a> i centrum av värdgalaxen. Det supermassiva objektet drar till sig enorma mängder material, en process som rubbar den omgivande galaxens uppbyggnad och kan slita sönder <a href="/wiki/Stj%C3%A4rna" title="Stjärna">stjärnor</a> i dess närhet. En typisk aktiv galax är <a href="/w/index.php?title=NGC_7052&action=edit&redlink=1" class="new" title="NGC 7052 [inte skriven än]">NGC 7052</a>. Dess <a href="/wiki/Ackretionsskiva" title="Ackretionsskiva">insamlingsskiva</a> har en diameter av 1 100 <a href="/wiki/Ljus%C3%A5r" title="Ljusår">ljusår</a> och själva kärnans massa har uppskattats till 300 miljoner <a href="/wiki/Solmassa" title="Solmassa">solmassor</a>. </p><p>AGN är de allra ljusstarkaste stadigvarande källorna till elektromagnetisk strålning i <a href="/wiki/Universum" title="Universum">universum</a>. De kan därför användas för att upptäcka mycket avlägsna objekt. Galaxkärnors aktivitet påverkas av tillgången på galaxmaterial inom räckhåll och aktiviteten kan såväl initieras som avta genom olika processer. Fördelningen av olika typer av aktiva galaxer varierar i rummet och därmed i tiden. Man har därför även sökt nyttja deras skenbara utveckling i tiden till att förse <a href="/wiki/Kosmologi" title="Kosmologi">kosmologiska</a> <a href="/wiki/Vetenskaplig_modell" title="Vetenskaplig modell">modeller</a> med begränsningar. </p><p>En mindre del av det ansamlade materialet (ca 10 %) avsöndras ofta som gas och strålning vinkelrätt mot ackretionsskivan i en så kallad <a href="/wiki/Relativistisk_jetstr%C3%A5le" title="Relativistisk jetstråle">jet</a>. En sådan jet kan bli flera gånger större än själva galaxen. En annan typ av recirkulation har noterats i form av hittills oförklarad <a href="/wiki/Stj%C3%A4rnbildning" title="Stjärnbildning">stjärnbildning</a> mycket nära <a href="/wiki/Vintergatan" title="Vintergatan">Vintergatans</a> och <a href="/wiki/Andromedagalaxen" title="Andromedagalaxen">Andromedagalaxens</a><sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-reference-link-bracket">[</span>1<span class="cite-reference-link-bracket">]</span></a></sup> centra, där unga blå stjärnor observerats. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Karakteristika_från_observationer_och_dataanalyser"><span id="Karakteristika_fr.C3.A5n_observationer_och_dataanalyser"></span>Karakteristika från observationer och dataanalyser</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&veaction=edit&section=1" title="Redigera avsnitt: Karakteristika från observationer och dataanalyser" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&action=edit&section=1" title="Redigera avsnitts källkod: Karakteristika från observationer och dataanalyser"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>AGN saknar en entydig observationell signatur. Men det går att lista ett antal drag som täcker en del av vad som historiskt tolkats vara viktiga kännetecken för AGN-system: </p> <ul><li>Optisk kontinuum-emission från kärnan. Denna syns närhelst vi har direkt insyn till insamlingsskivan. Jets kan även bidra till denna komponent av AGN-emission. Den optiska emissionen följer en ungefärlig potens-lag beroende på <a href="/wiki/V%C3%A5gl%C3%A4ngd" title="Våglängd">våglängden</a>.</li> <li>Infraröd emission från kärnan. Denna syns när ackretionsskivan och dess omgivning är skymd av gas och damm nära kärnan som återemitterar ljuset. Eftersom emissionen är <a href="/wiki/Termisk" class="mw-redirect" title="Termisk">termisk</a>, så kan den skiljas ut från jet- eller skiv-relaterade komponenter.</li> <li>Breda optiska emissionslinjer. Dessa bildas i joniserad gas nära det centrala supermassiva objektet. Linjerna är breda och snabbt föränderliga, eftersom det emitterande materialet är tätt packat och rör sig med höga hastigheter. Hastighetsvariationerna innehåller intressant information och analyseras med en ny statistisk metod som kallas <a href="/wiki/Reflexionsavbildning" title="Reflexionsavbildning">reflexionsavbildning</a>.</li> <li>Smala optiska emissionslinjer. Dessa kommer från ett större område med svalare joniserad gas och är därför smalare än de breda linjerna.</li> <li>Kontinuumemission i radio-området. Denna hänger alltid ihop med en enkel eller dubbel jet. Den uppvisar ett karakteristiskt spektrum från <a href="/wiki/Synkrotronstr%C3%A5lning" title="Synkrotronstrålning">synkrotronstrålning</a>.</li> <li>Röntgen kontinuumemission. Denna kan härröra både från en jet och från ackretionsskivans heta <a href="/wiki/Korona" title="Korona">korona</a> via spridningsprocesser: i båda fallen är det ett potens-lagsspektrum.</li> <li>Linjeemission i röntgen. Denna är ett resultat av att kalla tyngre grundämnen exiterats av röntgenkontinuumet. <a href="/wiki/Fluorescens" title="Fluorescens">Fluorescens</a> ger upphov till ett flertal emissionslinjer, av vilka linjerna av flerjoniserat järn omkring 6,4 <a href="/wiki/Elektronvolt" title="Elektronvolt">keV</a> är mest framträdande. Dessa linjer kan vara smala eller breda: <a href="/w/index.php?title=Bred_j%C3%A4rn-K-linje&action=edit&redlink=1" class="new" title="Bred järn-K-linje [inte skriven än]">relativistiskt breddade järnlinjer</a> kan också användas för att studera dynamiken hos insamlingsskivan i kärnans närhet och på så vis även det centrala mörka objektets natur.</li></ul> <div class="mw-heading mw-heading2"><h2 id="Se_även"><span id="Se_.C3.A4ven"></span>Se även</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&veaction=edit&section=2" title="Redigera avsnitt: Se även" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&action=edit&section=2" title="Redigera avsnitts källkod: Se även"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>Olika namn på aktiva galaxer beroende på hur de ser ut från <a href="/wiki/Jorden" title="Jorden">jorden</a>: </p> <ul><li><a href="/wiki/Seyfertgalax" title="Seyfertgalax">Seyfertgalax</a></li> <li><a href="/w/index.php?title=N-galax&action=edit&redlink=1" class="new" title="N-galax [inte skriven än]">N-galax</a></li> <li><a href="/wiki/Radiogalax" title="Radiogalax">Radiogalax</a></li> <li><a href="/w/index.php?title=Dubbel_radiok%C3%A4lla&action=edit&redlink=1" class="new" title="Dubbel radiokälla [inte skriven än]">Dubbel radiokälla</a></li> <li><a href="/wiki/Kvasar" title="Kvasar">Kvasar</a></li> <li><a href="/wiki/Blazar" title="Blazar">Blazar</a> t.ex. <a href="/wiki/BL_Lacertae-objekt" title="BL Lacertae-objekt">BL Lacertae-objekt</a> (BL Lacs) och <a href="/wiki/OVV-kvasar" title="OVV-kvasar">OVV-kvasarer</a></li></ul> <ul><li><a href="/wiki/Relativistisk_jet" class="mw-redirect" title="Relativistisk jet">Relativistisk jet</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="Noter">Noter</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&veaction=edit&section=3" title="Redigera avsnitt: Noter" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&action=edit&section=3" title="Redigera avsnitts källkod: Noter"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><a href="#cite_ref-1">^</a> <span class="reference-text"><a rel="nofollow" class="external text" href="https://fof.se/tidning/2005/8/artikel/unga-bla-stjarnor-forbryllar">Unga blå stjärnor F&F (nr8/2005)</a></span> </li> </ol></div> <div class="mw-heading mw-heading2"><h2 id="Litteraturreferenser">Litteraturreferenser</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&veaction=edit&section=4" title="Redigera avsnitt: Litteraturreferenser" class="mw-editsection-visualeditor"><span>redigera</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Aktiv_galaxk%C3%A4rna&action=edit&section=4" title="Redigera avsnitts källkod: Litteraturreferenser"><span>redigera wikitext</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li>Sparke, L.
