PEARLS: Discovery of Point-source Features within Galaxies in the North Ecliptic Pole Time Domain Field

The Astrophysical Journal
The first public 0.9–4.4 μ m NIRCam images of the North Ecliptic Pole Time Domain Field uncovered galaxies displaying point-source features in their cores as seen in the longer-wavelength filters. We visually identified a sample of 66 galaxies (∼1 galaxy

Calibrating Mid-infrared Emission Features as Diagnostics of Star Formation in Infrared-luminous Galaxies via Radiative Transfer Modeling

The Astrophysical Journal
Luminous infrared (IR) galaxies are key sites of obscured stellar mass assembly at z > 0.5. Their star formation rates (SFRs) are often estimated using the luminosities of the 6.2 and 11.2 μ m polycyclic aromatic hydrocarbon (PAH) features or those of ...

Spitzer IRAC infrared colours of submillimetre-bright galaxies [PDF]

, 2008
High-redshift submillimetre-bright galaxies identified by blank field surveys at millimetre and submillimetre wavelengths appear in the region of the Infra Red Array Camera (IRAC) colour–colour diagrams previously identified as the domain of luminous ...

Ultr-Luminous Infrared Galaxies: QSOs in Formation?

, 2002
We present new near-infrared Keck and VLT spectroscopic data on the stellar dynamics in late stage, ultra-luminous infrared galaxy (ULIRG) mergers . We now have information on the structural and kinematic properties of 18 ULIRGs, 8 of which contain QSO ...

Formation of Substructure in Luminous Submillimeter Galaxies (FOSSILS): Evidence of Multiple Pathways to Trigger Starbursts in Luminous Submillimeter Galaxies

The Astrophysical Journal
We present an analysis of rest-frame optical and far-infrared continuum emission in three luminous submillimeter galaxies (SMGs) at 3.0 ≲  z  ≲ 4.5.

NICMOS observations of luminous & ultraluminous infrared galaxies [PDF]

, 1999
HST NICMOS observations of a sample of 24 luminous (LIGs: L_(IR)[8-1000 μm] = 10^(11.0-11.99) L_⊙) and ultraluminous (ULIGs:L_(IR) ≳ 10^(12.0) L_⊙) infrared galaxies are presented.The observations provide, for the first time, high resolution HST imaging ...

Radio Agns Among Luminous Infrared Galaxies

, 2007
. An analysis of radio and FIR emission in over 1500 IRAS selected galaxies produces a good linear correlation between radio and FIR luminosity, indicating that star formation in normal field galaxies dominates the infrared luminosity in the local volume.
