“…This means that the density increases by at least a factor of 5 in the ring compared to the inner region and the region where the dust lane and the ring meet. These values are similar to the central region of M82, in which a mean ratio value of 4.2 +1.6 −1.2 was measured, corresponding to a mean electron density of 180 +209 −120 cm −3 across the central 50 (Petuchowski et al 1994). This is also consistent with the value of ∼220 cm −3 from the mid-infrared [SIII]18 μm/33 μm ratio over the same region (Dale et al 2006).…”

NGC 1097 is a nearby SBb galaxy with a Seyfert nucleus and a bright starburst ring. We study the physical properties of the interstellar medium (ISM) in the ring using spatially resolved far-infrared spectral maps of the circumnuclear starburst ring of NGC 1097, obtained with the PACS spectrometer on board the Herschel Space Observatory. In particular, we map the important ISM cooling and diagnostic emission lines of [

During our Herschel Lensing Survey (HLS) of massive galaxy clusters, we have discovered an exceptionally bright source behind the z = 0.22 cluster Abell 773, which appears to be a strongly lensed submillimeter galaxy (SMG) at z = 5.2429. This source is unusual compared to most other lensed sources discovered by Herschel so far, because of its higher submm flux (∼200 mJy at 500 μm) and its high redshift. The dominant lens is a foreground z = 0.63 galaxy, not the cluster itself. The source has a far-infrared (FIR) luminosity of L FIR = 1.1 × 10 14 /μ L , where μ is the magnification factor, likely ∼11. We report here the redshift identification through CO lines with the IRAM-30 m, and the analysis of the gas excitation, based on CO(7-6), CO(6-5), CO(5-4) detected at IRAM and the CO(2-1) at the EVLA. All lines decompose into a wide and strong red component, and a narrower and weaker blue component, 540 km s −1 apart. Assuming the ultraluminous galaxy (ULIRG) CO-to-H 2 conversion ratio, the H 2 mass is 5.8 × 10 11 /μ M , of which one third is in a cool component. From the C I( 3 P 2 − 3 P 1 ) line we derive a C I/H 2 number abundance of 6 × 10 −5 similar to that in other ULIRGs. The H 2 O p (2, 0, 2−1, 1, 1) line is strong only in the red velocity component, with an intensity ratio I(H 2 O)/I(CO) ∼ 0.5, suggesting a strong local FIR radiation field, possibly from an active nucleus (AGN) component. We detect the [NII]205 μm line for the first time at high-z. It shows comparable blue and red components, with a strikingly broad blue one, suggesting strong ionized gas flows.

“…In the local universe (z 0.1), [N ii]/[C ii] is reported for only six galaxies (mean ∼ 0.05, ranging from 0.01 to 0.07), with Herschel spectroscopy providing many recent observations: M82, Mrk 231, NGC 1097, Arp 220, NGC 1068, and NGC 4559 (Petuchowski et al 1994;Fischer et al 2010;Beirao et al 2010;Rangwala et al 2011;Spinoglio et al 2012;Croxall et al 2012). ALMA will facilitate a similar increase in data at high redshift in the near future, but thus far, only one high-redshift…”

ABSTRACT We present Submillimeter Array [C ii] 158 μm and Karl G. Jansky Very Large Array 12 CO(1-0) line emission maps for the bright, lensed, submillimeter source at z = 5.2430 behind A 773: HLSJ091828.6+514223 (HLS0918). We combine these measurements with previously reported line profiles, including multiple 12 CO rotational transitions, [C i], water, and [N ii], providing some of the best constraints on the properties of the interstellar medium in a galaxy at z > 5. HLS0918 has a total far-infrared (FIR) luminosity L FIR(8-1000 μm) = (1.6 ± 0.1) × 10 14 L μ −1 , where the total magnification μ total = 8.9 ± 1.9, via a new lens model from the [C ii] and continuum maps. Despite a HyLIRG luminosity, the FIR continuum shape resembles that of a local LIRG. We simultaneously fit all of the observed spectral line profiles, finding four components that correspond cleanly to discrete spatial structures identified in the maps. The two most redshifted spectral components occupy the nucleus of a massive galaxy, with a source-plane separation <1 kpc. The reddest dominates the continuum map (demagnified L FIR,component = (1.1 ± 0.2) × 10 13 L ) and excites strong water emission in both nuclear components via a powerful FIR radiation field from the intense star formation. A third star-forming component is most likely a region of a merging companion (ΔV ∼ 500 km s −1 ) exhibiting generally similar gas properties. The bluest component originates from a spatially distinct region and photodissociation region analysis suggests that it is lower density, cooler, and forming stars less vigorously than the other components. Strikingly, it has very strong [N ii] emission, which may suggest an ionized, molecular outflow. This comprehensive view of gas properties and morphology in HLS0918 previews the science possible for a large sample of high-redshift galaxies once ALM...
