The Most Luminous Galaxies [PDF]

, 2002
Ultraluminous galaxies in the local universe (z$\leq$0.2) emit the bulk of their energy in the mid and far-infrared. The multiwavelength approach to these objects has shown that they are advanced mergers of gas-rich spiral galaxies.

Resolved CO(1–0) Emission and Gas Properties in Luminous Dusty Star-forming Galaxies at z = 2–4

The Astrophysical Journal, 2023
We present the results of a survey of CO(1−0) emission in 14 infrared luminous dusty star-forming galaxies (DSFGs) at 2 < z < 4 with the NSF’s Karl G. Jansky Very Large Array.

Optical Properties of 4248 IRAS Galaxies

, 2005
We have investigated optical properties of 4248 infrared galaxies (IRGs) by positionally matching data from the IRAS and the SDSS DR3. Our sample includes 3 hyper luminous infrared galaxies (L >10^13Lsun) and 178 ultra luminous infrared galaxies (10 ...

Asca Observations of Luminous Infrared Starburst Galaxies [PDF]

Symposium - International Astronomical Union, 1999
We present recent results of X-ray observations of two luminous infrared galaxies, NGC3690+IC694 (Arp299) and NGC1614 obtained by the Japanese X-ray astronomical satellite ASCA. Both galaxies have quite high infrared luminosity (> 1011L⊙) and strong evidence of merger.

A relation of the PAH 3.3 um feature with star-forming activity for galaxies with a wide range of infrared luminosity

, 2013
For star-forming galaxies, we investigate a global relation between polycyclic aromatic hydrocarbon (PAH) emission luminosity at 3.3 um, L_PAH3.3, and infrared (8-1000 um) luminosity, L_IR, to understand how the PAH 3.3 um feature relates to the star ...

The stellar, molecular gas and dust content of the host galaxies of two z~2.8 dust obscured quasars [PDF]

, 2011
We present optical through radio observations of the host galaxies of two dust obscured, luminous quasars selected in the mid-infrared, at z=2.62 and z=2.99, including a search for CO emission.

ALMA 0.5 kpc Resolution Spatially Resolved Investigations of Nuclear Dense Molecular Gas Properties in Nearby Ultraluminous Infrared Galaxies Based on HCN and HCO+ Three Transition Line Data

The Astrophysical Journal, 2023
We present the results of our ALMA ≲0.5 kpc resolution dense molecular line (HCN and HCO ^+ J = 2–1, J = 3–2, and J = 4–3) observations of 12 nearby (ultra)luminous infrared galaxies ([U]LIRGs). After matching beam sizes of all molecular line data to the

The Aromatic Features in Very Faint Dwarf Galaxies

, 2009
We present optical and mid-infrared photometry of a statistically complete sample of 29 very faint dwarf galaxies (M_r > -15 mag) selected from the SDSS spectroscopic sample and observed in the mid-infrared with Spitzer IRAC. This sample contains nearby (
