Rise of the Titans: Gas Excitation and Feedback in a Binary Hyper-Luminous Dusty Starburst Galaxy at z~6
Dominik A. Riechers, Hooshang Nayyeri, Denis Burgarella +8
We report new observations toward the hyper-luminous dusty starbursting major merger ADFS-27 (z=5.655), using ATCA and ALMA. We detect CO 2-1, 8-7, 9-8, 10-9 and H2O(321-221) emiss…
Polycyclic Aromatic Hydrocarbons in Seyfert and star-forming galaxies
I. García-Bernete, D. Rigopoulou, A. Alonso-Herrero +3
Polycyclic Aromatic Hydrocarbons (PAHs) are carbon-based molecules resulting from the union of aromatic rings and related species, which are likely responsible for strong infrared…
Multi-phase feedback processes in the Sy2 galaxy NGC 5643
I. García-Bernete, A. Alonso-Herrero, S. García-Burillo +11
We study the multi-phase feedback processes in the central ~3 kpc of the barred Sy 2 galaxy NGC 5643. We use observations of the cold molecular gas (ALMA CO(2-1)) and ionized gas (…
Excitation and acceleration of molecular outflows in LIRGs: The extended ESO 320-G030 outflow on 200-pc scales
M. Pereira-Santaella, L. Colina, S. García-Burillo +7
We used high-spatial resolution (70 pc; 0.3") CO multi-transition (1-0, 2-1, 4-3, and 6-5) ALMA data to study the physical conditions and kinematics of the cold molecular outflow i…
Simulating gas kinematic studies of high-redshift galaxies with the HARMONI Integral Field Spectrograph
Mark L. A. Richardson, Laurence Routledge, Niranjan Thatte +4
We present simulated observations of gas kinematics in galaxies formed in 10 pc resolution cosmological simulations with the hydrodynamical + N-body code RAMSES, using the new RAMS…
Extinction in the 11.2 micron PAH band and the low L_11.2/L_IR in ULIRGs
Antonio Hernan-Caballero, Henrik W. W. Spoon, Almudena Alonso-Herrero +9
We present a method for recovering the intrinsic (extinction-corrected) luminosity of the 11.2 micron PAH band in galaxy spectra. Using 105 high S/N Spitzer/IRS spectra of star-for…
ALMA [N ıı] 205 μm Imaging Spectroscopy of the Lensed Submillimeter galaxy ID 141 at redshift 4.24
Cheng Cheng, Xiaoyue Cao, Nanyao Lu +17
We present the Atacama Large Millimeter/submillimeter Array (ALMA) observation of the Sub-millimeter galaxy (SMG) ID 141 at z=4.24 in the [N II] 205 m line (hereafter [N II]) an…
Cold molecular gas and PAH emission in Seyfert galaxies
A. Alonso-Herrero, M. Pereira-Santaella, D. Rigopoulou +15
We investigate the relation between the detection of the m PAH feature in the nuclear (pc) regions of 22 nearby Seyfert galaxies and the properties of the c…
Dust and gas content of high-redshift galaxies hosting obscured AGN in the CDF-S
Q. D'Amato, R. Gilli, C. Vignali +14
Obscured AGN represent a significant fraction of the entire AGN population, especially at high redshift (~70% at z=3--5). They are often characterized by the presence of large gas…
Searching for molecular gas in/outflows in the nuclear regions of five Seyfert galaxies
A. J. Domínguez-Fernández, A. Alonso-Herrero, S. García-Burillo +8
AGN-driven outflows are believed to play an important role in regulating the growth of galaxies mostly via negative feedback. However, their effects on their hosts are far from cle…
ALMA Imaging of the CO(7-6) Line Emission in the Submillimeter Galaxy LESS 073 at redshift 4.755
Yinghe Zhao, Nanyao Lu, Tanio Díaz-Santos +8
In this paper we present our imaging observations on the CO(7-6) line and its underlying continuum emission of the young submillimeter galaxy LESS 073 at redshift 4.755, using the…
Deceptively cold dust in the massive starburst galaxy GN20 at
Isabella Cortzen, Georgios E. Magdis, Francesco Valentino +13
We present new observations, carried out with IRAM NOEMA, of the atomic neutral carbon transitions [CI](1-0) at 492 GHz and [CI](2-1) at 809 GHz of GN20, a well-studied star-bursti…
[CI](1-0) and [CI](2-1) in resolved local galaxies
Alison F. Crocker, Eric Pellegrini, J. -D. T. Smith +16
We present resolved [CI] line intensities of 18 nearby galaxies observed with the SPIRE FTS spectrometer on the Herschel Space Observatory. We use these data along with resolved CO…
