Abstract
The question of how much gas cools in the cores of clusters of galaxies has been the focus of many, multiwavelength studies in the past 30 years. In this letter we present the first detections of the strongest atomic cooling lines, [CII], [OI] and [NII] in two strong cooling flow clusters, A1068 and A2597, using HersrcheL-PACS. These spectra indicate that the substantial mass of cold molecular gas (> 109 M◦.) known to be present in these systems is being irradiated by intense UV radiation, most probably from young stars. The line widths of these FIR lines indicate that they share dynamics similar but not identical to other ionised and molecular gas traced by optical, near-infrared and CO lines. The relative brightness of the FIR lines compared to CO and FIR luminosity is consistent with other star-forming galaxies indicating that the properties of the molecular gas clouds in cluster cores and the stars they form are not unusual. These results provide additional evidence for a reservoir of cold gas that is fed by the cooling of gas in the cores of the most compact clusters and provide important diagnostics of the temperature and density of the dense clouds this gas resides in.

In this letter we present the first detections of the strongest atomic cooling lines, [CII], [OI] and [NII] in two strong cooling flow clusters, A1068 and A2597, using HersrcheL-PACS. These spectra indicate that the substantial mass of cold molecular gas (> 10<sup>9</sup> M<sub>◦.</sub>) known to be present in these systems is being irradiated by intense UV radiation, most probably from young stars. The line widths of these FIR lines indicate that they share dynamics similar but not identical to other ionised and molecular gas traced by optical, near-infrared and CO lines. The relative brightness of the FIR lines compared to CO and FIR luminosity is consistent with other star-forming galaxies indicating that the properties of the molecular gas clouds in cluster cores and the stars they form are not unusual. These results provide additional evidence for a reservoir of cold gas that is fed by the cooling of gas in the cores of the most compact clusters and provide important diagnostics of the temperature and density of the dense clouds this gas resides in.</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 observations of FIR emission lines in brightest cluster galaxies</s1></fA08><fA11 i1="01" i2="1"><s1>EDGE (A.

The line widths of these FIR lines indicate that they share dynamics similar but not identical to other ionised and molecular gas traced by optical, near-infrared and CO lines. The relative brightness of the FIR lines compared to CO and FIR luminosity is consistent with other star-forming galaxies indicating that the properties of the molecular gas clouds in cluster cores and the stars they form are not unusual. These results provide additional evidence for a reservoir of cold gas that is fed by the cooling of gas in the cores of the most compact clusters and provide important diagnostics of the temperature and density of the dense clouds this gas resides in.</EA><CC>001E03</CC><FD>Raie émission; Amas galaxies; Ecoulement refroidissement; Gaz froid; Gaz moléculaire; Rayonnement UV; Etoile jeune; Largeur raie; Dynamique; Luminosité; Galaxies elliptiques; Nuage moléculaire; Nuage dense; Gaz dense; Matière intraamas</FD><ED>Emission line; Galaxy clusters; Cooling flow; Cold gas; Molecular gas; Ultraviolet radiation; Young stars; Line widths; Dynamics; Luminosity; Elliptical galaxies; Molecular clouds; Dense cloud; Dense gas; Intracluster matter</ED><SD>Raya emisión; Flujo enfriamiento; Gas frío; Gas molecular; Nube densa; Gas denso; Materia intracúmulo</SD><LO>INIST-14176.354000192501260460</LO><ID>11-0086167</ID></server></inist></record>Pour manipuler ce document sous Unix (Dilib)
