ALMA Observations of Warm Dense Gas in NGC 1614 --- Breaking of Star Formation Law in the Central kpc
C. K. Xu, C. Cao, N. Lu +20
We present ALMA Cycle-0 observations of the CO (6-5) line emission and of the 435um dust continuum emission in the central kpc of NGC 1614, a local luminous infrared galaxy (LIRG)…
Early Science with the Large Millimeter Telescope: Exploring the Effect of AGN Activity on the Relationships Between Molecular Gas, Dust, and Star Formation
Allison Kirkpatrick, Alex Pope, Itziar Aretxaga +9
The molecular gas, H, that fuels star formation in galaxies is difficult to observe directly. As such, the ratio of to is an observational esti…
High-Resolution Radio Continuum Measurements of the Nuclear Disks of Arp 220
Loreto Barcos-Muñoz, Adam K. Leroy, Aaron S. Evans +16
We present new Karl G. Jansky Very Large Array radio continuum images of the nuclei of Arp 220, the nearest ultra-luminous infrared galaxy. These images have both the angular resol…
Accretion-Inhibited Star Formation in the Warm Molecular Disk of the Green-valley Elliptical Galaxy NGC 3226
P. N. Appleton, C. Mundell, T. Bitsakis +7
We present archival Spitzer photometry and spectroscopy, and Herschel photometry, of the peculiar "Green Valley" elliptical galaxy NGC~3226. The galaxy, which contains a low-lumino…
Inefficient Star Formation In Extremely Metal Poor Galaxies
Yong Shi, Lee Armus, George Helou +5
The first galaxies contain stars born out of gas with little or no metals. The lack of metals is expected to inhibit efficient gas cooling and star formation but this effect has ye…
Providing stringent star formation rate limits of z2 QSO host galaxies at high angular resolution
Andrey Vayner, Shelley A. Wright, Tuan Do +3
We present integral field spectrograph (IFS) with laser guide star adaptive optics (LGS-AO) observations of z=2 quasi-stellar objects (QSOs) designed to resolve extended nebular li…
[CII] 158 m Emission as a Star Formation Tracer
R. Herrera-Camus, A. D. Bolatto, M. G. Wolfire +23
The [CII] 157.74 m transition is the dominant coolant of the neutral interstellar gas, and has great potential as a star formation rate (SFR) tracer. Using the Herschel KINGFISH…
Star formation relations and CO SLEDs across the J-ladder and redshift
T. R. Greve, I. Leonidaki, E. M. Xilouris +19
We present FIR-CO luminosity relations () for the full CO rotational ladder from J=1-0 to J=13-12 for 62 local (z < 0.1) (Ultra) Luminous…
The InfraRed Imaging Spectrograph (IRIS) for TMT: Overview of innovative science programs
Shelley A. Wright, James E. Larkin, Anna M. Moore +22
IRIS (InfraRed Imaging Spectrograph) is a first light near-infrared diffraction limited imager and integral field spectrograph being designed for the future Thirty Meter Telescope…
Mid-Infrared Properties of Luminous Infrared Galaxies II: Probing the Dust and Gas Physics of the GOALS Sample
Sabrina Stierwalt, Lee Armus, Vassilis Charmandaris +13
The Great Observatories All-Sky LIRG Survey (GOALS) is a comprehensive, multiwavelength study of luminous infrared galaxies (LIRGs) in the local universe. Here we present the resul…
Extended [CII] Emission in Local Luminous Infrared Galaxies
T. Diaz-Santos, L. Armus, V. Charmandaris +20
We present Herschel/PACS observations of extended [CII]157.7μm line emission detected on ~ 1 - 10 kpc scales in 60 local luminous infrared galaxies (LIRGs) from the Great Observato…
Warm Molecular Gas in Luminous Infrared Galaxies
N. Lu, Y. Zhao, C. K. Xu +18
We present our initial results on the CO rotational spectral line energy distribution (SLED) of the to 1 transitions from up to from Herschel SPIRE spectroscop…
Polycyclic aromatic hydrocarbon feature deficit of starburst galaxies in the AKARI North Ecliptic Pole Deep Field
K. Murata, H. Matsuhara, H. Inami +6
We study the behaviour of polycyclic aromatic hydrocarbon emission in galaxies at z=0.3-1.4 using 1868 samples from the revised catalogue of AKARI North Ecliptic Pole Deep survey.…
ALMA Observations of Warm Molecular Gas and Cold Dust in NGC 34
C. K. Xu, C. Cao, N. Lu +17
We present ALMA Cycle-0 observations of the CO (6-5) line emission (rest-frame frequency = 691.473 GHz) and of the 435 dust continuum emission in the nuclear region of NGC 34,…
