ALMA Spatially Resolved Dense Molecular Gas Survey of Nearby Ultraluminous Infrared Galaxies [PDF]
Astrophysical Journal Supplement Series, 2019 We present the results of our ALMA HCN J=3-2 and HCO+ J=3-2 line observations of a uniformly selected sample (>25) of nearby ultraluminous infrared galaxies (ULIRGs) at z 10^5 cm^-3) molecular gas, with an estimated mass of >10^9 Msun within the nuclear (

The near-infrared morphology of ultraluminous infrared galaxies [PDF]
The Astrophysical Journal, 1990 Near-infrared images at 1.25, 1.65, and 2.2 microns have been obtained of nine galaxies from the IRAS Bright Galaxy Sample with infrared luminosities greater than 10 to the 12th solar luminosities. Two of the 2.2-micron images reveal previously undetected double nuclei, increasing the number of close double nuclei known for this samples from two to ...

Herschel views on ultra-luminous X-ray sources [PDF]
, 2012 The nature of ultra-luminous X-ray sources (ULXs), which are off-nuclear extragalactic X-ray sources that exceed the Eddington luminosity for a stellar-mass black hole, is still largely unknown.

The Astrophysical Journal, 2023 We use archival ALMA observations of the HCN and CO J = 1–0 transitions, in addition to the radio continuum at 93 GHz, to assess the relation between dense gas, star formation, and gas dynamics in 10 nearby (ultra)luminous IR galaxies (U)LIRGs and late ...

The Cosmic History of Black Hole Growth from Deep Multiwavelength Surveys
Advances in Astronomy, Volume 2012, Issue 1, 2012., 2012 Significant progress has been made in the last few years on understanding how supermassive black holes form and grow. In this paper, we begin by reviewing the spectral signatures of active galactic nuclei (AGN) ranging from radio to hard X‐ray wavelengths.

Ultraluminous Infrared Galaxies: Mergers of Sub‐L* Galaxies? [PDF]
The Astrophysical Journal, 2001 A sample of 27 low-redshift, mostly cool, ultraluminous infrared galaxies (ULIRGs) has been imaged at 1.6 μm with the Hubble Space Telescope (HST) Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). The majority (67%) of the sample's galaxies are multiple-nucleus galaxies with projected separations of up to 17 kpc, and the rest of the sample ...

Gravitational Waves from Supermassive Black Hole Binaries in Ultraluminous Infrared Galaxies [PDF]
Astrophysical Journal, 2018 Gravitational waves (GWs) in the nanohertz band are great tools for understanding the cosmological evolution of supermassive black holes (SMBHs) in galactic nuclei.

Structural and Morphological Properties of Ultraluminous Infrared Galaxies at 1 < z < 3
Open Astronomy, 2015 Using the Hubble Space Telescope (HST)/Wide Field Camera 3 (WFC3) near-infrared high-resolution imaging from the 3D-HST survey, we analyze the morphology and structure of 502 ultraluminous infrared galaxies (ULIRGs; LIR > 1012L⊙) at 1 < z < 3. Their rest-
