ASTRO-F - The next generation of mid-infrared surveys

open access: yes, 2001
We present basic observational strategies for ASTRO-F (also known as the Imaging Infra Red Surveyor (IRIS)) to be launched in 2004 by the Japanese Institute of Space and Astronautical Science (ISAS). We examine 2 survey scenarios, a deep ~1sq.deg. survey

Spitzer Quasar and ULIRG evolution study (QUEST): I. The origin of the far infrared continuum of QSOs [PDF]

open access: yes, 2006
This paper addresses the origin of the far-infrared (FIR) continuum of QSOs, based on the Quasar and ULIRG Evolution Study (QUEST) of nearby QSOs and ULIRGs using observations with the Spitzer Space Telescope. For 27 Palomar-Green QSOs at z

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

open access: yesThe 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.

Sensitive Radio Observations of High Redshift Dusty QSOs [PDF]

open access: yes, 1999
We present sensitive radio continuum imaging at 1.4 GHz and 4.9 GHz of seven high redshift QSOs selected for having a 240 GHz continuum detection, which is thought to be thermal dust emission.

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

open access: yesThe 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.

Compact starbursts in ultraluminous infrared galaxies

open access: yesThe 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.

Large-scale Overdensity of Lyman Break Galaxies around the z = 6.3 Ultraluminous Quasar J0100 + 2802 [PDF]

open access: yesAstrophysical Journal
We study the environment of the z = 6.33 ultraluminous quasar SDSS J010013.02+280225.8 (J0100) to understand its association with large-scale structure.

A General Theory of Turbulence-regulated Star Formation, from Spirals to Ultraluminous Infrared Galaxies [PDF]

open access: yes, 2005
We derive an analytic prediction for the star formation rate in environments ranging from normal galactic disks to starbursts and ULIRGs in terms of the observables of those systems.

Star-Forming AGN Host Galaxies

open access: yes, 2001
The symbiosis of nuclear activity and star-formation in galaxies, as manifested in their spectral energy distributions (SEDs) is reviewed. Attention is drawn to an Hertzsprung-Russell diagram-equivalent for such objects, as well as to the importance of ...
