Dynamics of Molecular Gas in the Central Region of the Quasar I Zwicky 1

The Astrophysical Journal, 2023
We present a study of the molecular gas distribution and kinematics in the cicumnuclear region (radii ≲2 kpc) of the z ≈ 0.061 quasar I Zwicky 1 using a collection of available Atacama Large Millimeter/submillimeter Array observations of the carbon ...

Characterizing the Molecular Gas in Infrared Bright Galaxies with CARMA

The Astrophysical Journal
We present the CO(1–0) maps of 28 infrared-bright galaxies from the Great Observatories All-Sky Luminous Infrared Galaxy Survey (GOALS) taken with the Combined Array for Research in Millimeter Astronomy (CARMA).

Extended Star Formation in Luminous Infrared Galaxies at z ∼ 1 in the SMILES Field

The Astrophysical Journal
Luminous infrared galaxies (LIRGs) and ultraluminous infrared galaxies (ULIRGs) in the local Universe are highly centrally concentrated in the mid-infrared (MIR) and substantially more likely than non-(U)LIRGs to be involved in mergers.

The Nature of Ultraluminous Infrared Galaxies [PDF]

Symposium - International Astronomical Union, 2001
The Infrared Space Observatory (ISO) has for the first time made possible mid- and far-infrared spectroscopic studies of nearby and moderate redshift, dusty ultraluminous infrared galaxies (ULIRGs). We discuss recent SWS, LWS, ISOPHOT-S and ISOCAM (CVF) results on ULIRGs, addressing the following topics: What powers ULIRGs?

Compact starbursts in ultraluminous infrared galaxies

The Astrophysical Journal, 1991
The 40 ultraluminous galaxies in the IRAS Bright Galaxy Sample of sources stronger than S = 5.24 Jy at lambda = 60 microns were mapped with approximately 0.25 arcsec resolution at 8.44 GHz. Twenty-five contain diffuse radio sources obeying the FIR-radio correlation; these are almost certainly starburst galaxies.

Direct Evidence for Active Galactic Nuclei Feedback from Fast Molecular Outflows in Reionization-era Quasars

The Astrophysical Journal
Galactic outflows driven by rapidly accreting quasars at high redshift are widely expected to play a key role in the short- and long-term future evolution of their host galaxies.

Building on the Archives: Connecting the CN/CO Intensity Ratio with Global Galaxy Properties in Nearby U/LIRGs

The Astrophysical Journal
We use the CN/CO intensity ratio to obtain the dense gas fraction, f _dense , for a sample of 16 ultraluminous and luminous infrared (IR) galaxies and compare f _dense with a suite of global galaxy properties.

A Complete 16 μm Selected Galaxy Sample at z ∼ 1. II. Morphological Analysis

The Astrophysical Journal
We present a morphological analysis of the 16 μ m flux-density-limited galaxy sample at 0.8 < z < 1.3 from Huang et al. (2021). At the targeted redshift, the 16 μ m emission corresponds to the polycyclic aromatic hydrocarbon feature from intense star ...
